Knoxville Crawl Space Remediation

Crawl Spaces in Knoxville  have been always around, but they became increasingly popular when homeowners started to recognize the improved convenience they have. Compared to the conventional floor setups and concrete floors, crawlspaces granted easy access to the plumbing setup and air ducts, and repairing them became effortless. Moreover, crawlspaces were also used as a storage facility. However, like any good thing in the world, crawlspaces also have its fair share of problems: trapped moisture, vermin, termites, and carpenter ants; invasion of wildlife and accumulation of foul gases to name a few.

I’ve been doing  crawl space encapsulation in Knoxville for more than two decades now. A good number of correspondences I have addressed were always concerning the foul smell and bad odors that are generated from crawlspaces. It’s imperative to recognize the root causes behind such foul odors and we need to work on strategies that will eliminate the root causes. Crawlspace encapsulation is relatively a new technique which will help you to protect your crawl space, and the health of your family. However, you need to know how to choose the right encapsulation system for your home.

By encapsulating your crawl space, you no longer have to worry about rodents or other wild animals invading your crawl space, moisture accumulation, termites and foul smell that was haunting you for long. A Do-It-Yourself encapsulation kit will undisputedly help you to protect your home from unwanted disasters.

A basement is prone to all types of foundation issues like, cracks in the interior and exterior walls, leaks, soil pressure, excessive moisture, seepage and dampness. These problems get worse over time and cause long term damage to your home, if left untreated. In order to enhance the structural integrity of your home, it is very important to take professional help for basement foundation repair. A professional will ensure that the problem is resolved efficiently.

Many properties experience foundation issues at some or the other time and it is important to know how severe the problem is to look for a treatment that offers a permanent solution. A basement foundation repair can be easily done if you have basic information about the ways to handle such repairs. There are various methods of repairing the foundation of a home. If there is some serious damage, it is advisable to take professional help. For general maintenance, you can either go for mortar application or patching repairs.

Some indications which suggest that you should go for basement foundation repair includes:

- Uneven Floors
- Water collection
- Cracks at entry or exit doors
- Doors not closing or opening properly

Cracks are the most common type of foundation maintenance issues. They are usually found in older basements and are caused due to the changes in the soil below the basement. Shallow foundations are more prone to cracks.

How To Clean Cracks

Once you have identified cracks in the foundation, you need to first clean them comprehensively. Cleaning is important as it not only helps in knowing the type of repair required, but also helps in proper application of the adhesive material. You can use a chisel to remove loose fragments from the cracks and then inspect it to find the right repair method.

If the cracks have just begun to show, you can use either hydraulic cement or Portland mortar to seal the cracks. These materials come with easy to follow instructions and can also be used to resolve any visible unevenness along the basement floor.

If your basement foundation is facing standing water problem, the moisture seepage can cause cracks in the drywall. To patch the leaky spots is the most effective solution for dealing with this problem.

To ensure that repeated basement foundation repairs are not needed, the groundwater should be directed away from the foundation.

A professional basement foundation repair company can be hired to repair foundation cracks, basement walls, stabilize the foundation, install foundation guard, repair eroded, bowed or unstable walls and remove mold problems. A strong basement foundation increases the value of your home.

Crawl Space Vapor Barrier Basics

cost to encapsulate crawl space

Crawl spaces are known for their aesthetic presence-- NOT! When you talk about a crawl space you probably touch upon the dirt floor, the mold buildup, the puddles, the stench, oh and you can't forget about the insulation falling from the ceiling or the dusty old vents.

Unfortunately, this environment can cause a whole lot more damage to the rest of your home than you may think.

The Moisture

Crawl spaces and basements have huge problems with moisture. The stack effect is the proper name for the well-known process of warm air rising, which absolutely has a lot to do with moisture.

When the hot and humid air from the outside enters into the crawl space, the air begins to cool and the warm air pushes and exits through the upper levels. When the hot air cools by even one degree, the relative humidity rises by 2.2 percent.

This is why you find condensation and water buildup on other surfaces! Once this moisture begins to build and the humidity rises in the space mold begins to grow. Mold will continue growing and prospering if it has moisture, organic material to eat and a comfortable temperature. You cannot remove mold by wiping it away, but you remove mold by eliminating the source of moisture.

In other words-- close the vents, seal the space and install a sump pump!

The Vents

As we just learned, air tends to rise within a home. So, when old-school thought encouraged people to install vents, it was unfortunately saying that air would come in through one vent and go out the other vent. This is not the case. Instead, the air comes in through both vents increasing moisture and humidity. In addition, as the crawl spaces conditions worsen due to the vents, the air quality in your home also lessens.

It's been estimated that a third to one half of the air on the first level actually comes from the crawl space, so whatever is growing and prospering beneath your home you can be sure to be breathing in throughout the rest of your home.

In addition, some spaces have fans as well. A fan will only blow the mess around and worsen the problem. Both of these "solutions" also heighten your energy bills and shorten the life of some of your homes heating and cooling appliances. Your air conditioning will be working a whole lot harder to cool and your heating system will be working very hard to keep your home warm. Unfortunately, the vents and fans in your crawl space are a big factor in your energy waste and increase in expenses.

The Solution

Since crawl spaces have problems with moisture control and mold growth the best solution will close-off air flow from the outside and prevent moisture from entering through the soil, cracks and vents. In addition, the solution must prevent mold growth and include a water drainage system for when leaks occur and water somehow makes its way into the space.

This solution is to install the CleanSpace Crawl Space Encapsulation System, which will enclose the entire crawl space with a vapor barrier that also separates the space from the soil foundation. In addition, you can close-off the vents and include a sump pump drainage system.

No more vents, no more fans equals better air quality and a cleaner environment.

The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Turkey Creek Knoxville  don’t think twice about their crawl space unless they have to make repairs to plumbing, heating ducts or house wiring. While often thought of as no more than a storage area, it also has a tremendous impact on the overall indoor air quality of the entire home.

The Best Crawl Space Moisture Control In Turkey Creek TN

By default, the air quality of a crawl space is typically poor. Mold, mildew, radon gas and poor energy efficiency all create several problems. The air that circulates within it eventually makes its way up through the living space. Scientific studies show that up to 50% of living space air originates from the lowest level of the home. With homeowners more concerned about their home’s indoor air quality, the encapsulating of crawl spaces has become a popular solution for such problems.

A damp crawl space creates a safe harbor for harmful molds, in addition to dust mites, termites and other bugs that can infest the home. The presence of excessive moisture will also create a serious problem with the probability for the wooden structure of a home to deteriorate. Crawl space vents pose a further problem. While believed to be a solution to moisture problems, they, unfortunately, make the problem worse. As it turns out, the vents allow cold air and moisture in, which rises into the living area and therefore decreases the heating efficiency of the entire home.

Another all-too-common problem associated with crawl spaces is radon gas. Though it cannot be seen, smelled or tasted, radon is a radioactive gas that can contribute to poor health, including cancer. Radon gas makes its way through the earth, into the crawl space and the home’s living space. According to the U.S.E.P.A., radon gas is the number one leading cause of lung cancer in non-smokers.

Ignoring these various conditions is not recommended for both long-term health and energy usage. Fully encapsulating a crawl space – by both sealing and insulating – is a fully efficient measure in addressing such problems. It makes sense to maintain and improve the lower level area in order to maximize healthy living conditions and home resale value.

While there are several systems for encapsulating, a zero perm liner system that also insulates and reflects heat provides the most benefits. With a proper floor and wall liner, the area will not only be well insulated but will seal out moisture, bug infestation, and radon gas. Other components to look for in a system include a radon gas-dispersing drain fabric, a radon gas ventilation pipe, and a ceiling heat shield.

A complete system with all of the above components will allow any soil gasses – including radon gas – that naturally occur under the liner system, to wick through the drain fabric and escape out through the ventilation pipe. While improved indoor air quality is the primary benefit of a sealed and insulated crawl space, the homeowner will also appreciate a bright, clean, and dry storage area; the ridding of musty smells; less energy usage; and tax credits. Contractors encapsulating crawl spaces will have more to offer to their clients when they can assure the peace of mind with improved indoor air quality.

A Closed, Sealed Crawlspace - What a Really Bad Idea

Owning a home with a basement can give us additional living space that is not typically available in a home with a crawl space. Many people put recreational rooms in the basement as well as using them for storage and often as a personal workshop. It may be difficult, however, whenever water in the basement becomes a problem. There are really two different ways in which water can invade this area of our home, both of which will take some form of waterproofing to correct. They can either come in slowly, almost undetected by us or it can quickly invade our basement and cause it to be flooded.

Since the basement is below ground level, moisture is often a problem, even if it is not visible. It may show up as mold or mildew that begins to appear on the walls and although you cannot actually see the moisture that is present, there are plenty of telltale signs that will help to identify the fact that you have a problem.

Doing a little bit of basement waterproofing for this usually means putting a specific type of paint on the walls or perhaps even spraying them down with chemicals so that they are impervious to mold growth. It may also help if you run a basement dehumidifier on a regular basis, even after you have completed the basement waterproofing project.

The other way that water can invade our basement is all at one time which can cause it to be flooded. I have personally had a difficulty with this for many years and it can be destructive, especially if you use the basement for living space or storage. If the water is coming in at one specific location, sealing that location in some way or another may help to cure the problem a little bit.

There may be times, however, whenever more drastic measures need to be taken. If you're basement floods on a regular basis, you may need to dig down to the bottom of your foundation on the outside of the walls and install a French drain. This will divert any water away from the house so that it does not end up in your basement.

Having a problem with water in your basement is simply keeping you from enjoying part of your house. Although waterproofing your basement is going to take a little bit of work, it will all be well worth the effort whenever you can take this part of your home back again.

What to Do About Basement Waterproofing Before It's Too Late

In recent years, the idea of indoor air quality control has become a bigger concern to the basement waterproofing industry. When I began working with the industry over 20 years ago, the idea of basement waterproofing was exclusive to the controlling of and prevention of water seepage and flooding. With homeowners becoming more aware of radon gas infiltration, moisture and mildew, and other soil gases, waterproofers have the perfect opportunity to better serve their customers by addressing such needs.

Musty smells, moisture and radon gas - all common problems in a basement and/or crawl space, are solvable by enacting some of the most basic waterproofing techniques. Improving indoor air quality, beginning from the basement and/or crawl space will impact the air quality of the entire home. Over 50 percent of the air that circulates through the home's living space originates from the basement and or crawl space. When the air quality of the basement or crawl space is poor, chances are, the entire home's air quality is poor or soon will be.

One of the first measures a contractor can do to address such concerns is by applying a sodium based silicate spray onto the basement's walls and floors. Such a spray typically reacts with the concrete's free lime, resulting in the formation of an expanded crystalline structure beneath the surface. The application of a deep-penetrating concrete sealer stops water vapor and radon gas from permeating the porous surfaces. This allows the concrete to become dense, increasing its resistance to various vapors and gases. Such sealants usually can be applied with a low-pressure hand sprayer.

When applying the right sodium based silicate spray, some of the additional advantages may include the reduction of spalling from freeze and thaw cycles; improving a concrete structure's resistance to most soils, acids, oils and salts; and protecting against efflorescence and leaching - specific results will vary pending the type of spray that is applied.

It is recommended to clean the concrete surface prior to application. Any dirt, oil or foreign substances may hinder the effectiveness of the spray. After such a spray is applied, the surface should be flushed with water before drying.

The prevention of moisture and soil gases permeating through concrete surfaces goes a long way in reducing the growth of mold and eliminating the musty smell that often plagues a basement and/or crawl space. Waterproofing contractors have always been called to address immediate water problems for the short-term; with indoor air quality control, contractors can now offer a viable long-term service that provides their customers with the ultimate peace of mind.

DIY Basement Foundation Repair

Crawl spaces are proven to be one of the most convenient floor setups because they can provide sufficient space for air conditioning, ventilation and heating systems, but vapor can really destroy your crawl space, and this is where a crawl space vapor barrier can help you.

Too much moisture under your home can be a real headache as this can affect the structure of your home. Mold and mildew not only destroy your crawl space but they can spread to your wooden flooring and carpet too. By installing a crawl space vapor barrier, you are leaving no room for mold and mildew to survive under your home. This way, you can maintain the strength and aesthetics of your home for several years.

A disappointing fact that I have observed is that many homeowners often underestimate the importance of installing moisture controllers and by the time they realize the importance, it will be too late. Termites and molds would have eaten up a good part of their crawl space. Second scenario is even worse: homeowners who find out that their home structure is under serious threat will install a vapor barrier, without ever considering its quality. Apart from wasting a significant amount of money, you will be left with no results because such insulations won't work well more than a few years and in some cases, only a couple of months.

If you do not miss the nitty-gritty of a professional installation, you can lead a healthy life in your home for several decades.

· Measurement: Before buying the barrier, you need to measure the length, width and height of your crawl space. This will give you an estimate on how much barrier sheet you need. It's always a good idea to buy some extra so that you won't run short on materials even if you wasted some sheet.

· Energy Efficiency: There are two benefits in buying energy efficient liner sheet. They will help you to save a good amount on energy bills, which will provide you excellent comfort in your home and the second advantage is the tax benefits. I have noticed that some store owners stress on the cheaper price and mislead their buyers on the long-term benefits of energy efficient sheets. You will be using them for several years and an energy efficient insulation will cut down your energy bills significantly all these years.

· Product Quality: Ideally, sheets with 60mil thickness provide you the best protection. Your sheet should provide you a minimum warranty of 20 years and it should be antimicrobial, rodent proof and termite proof. If you can't see these certifications on the sheets, you most likely are going to face a huge loss.

These are some of the important things to be considered when you are on the lookout for a crawl space vapor barrier. Needless to say, maintaining your home is the best idea compared to buying a new one because you can significantly improve the living quality of your home for a much lower cost. By installing energy efficient barriers with tax benefits, you are also fulfilling your social responsibility of conserving energy.

Addressing Moisture, Mold and Radon Gas in Basements and Crawl Spaces With Application of a Deep-Pen

Many homeowners try to cut costs and increase their home's comfort level by installing a crawl space vapor barrier. This will instantly make your home healthier for you and your family, and prevent moisture damage, mold, mildew, foul smells and odors.

Most homeowners tend to look at their crawl space as separate space from their home, but in reality, the two are one. Water vapors that surface from the ground are continuously entering, creating undesirable conditions for you, your family, and your home.

Purpose

The purpose of a crawl space vapor barrier is to stop moisture and wetness from entering and affecting the floor and walls of your basement. Moisture tends to flow from warmer to colder spaces.

Many homeowners don't realize the importance of the proper installation, in order to keep moisture and water vapors from getting in the walls and floor of your basement-- condensation can lead to expensive structural damage. Also, if you can help control the moisture and dampness, you can greatly reduce the amount of energy required to cool and heat your home.

Preparation

When considering the installation of a vapor barrier, take into consideration two spaces in your home; the crawl space and the attic. Humidity tends to build in the walls of both these areas causing mold, mildew and dry rot. This can cause severe health issues for adults and children, especially for those with asthma, breathing difficulties, and allergies. In addition, it can cause severe structural damage to your home.

Some homeowners think that because they insulate the floor joists there is no need to do any additional work, but these items do not serve the same purpose!

Tips for Installation

One of the most popular do-it-yourself vapor barrier products is polyethylene, or plastic sheeting. This plastic sheeting comes in various thicknesses; 4mm, 6mm and 10mm.

With today's technology, this product is made from a high quality material, resistant to rips and punctures. Always check the soil so there aren't any objects or materials that may damage the lining. The slightest puncture, rip or tear could compromise the entire system.

Always, make sure the space is dry before you begin any repairs. To remove the moisture, you may need a dehumidifier.

Overlap the barrier a minimum of 12 inches on the side walls. Be sure it is tight. Use furring strips and masonry nails to firmly secure the lining then caulk along the joints.

Seal all the seams with a heavy duty tape. However, it is recommended not to use tapes that are not specially designed for sealing vapor barriers. When working in the basement you will be forced to contend with pipes, make the proper cuts and seal securely with tape.

The completion of your crawl space vapor barrier will be the best investment you can make in your home.

Proper Crawl Space Ventilation Can Improve Living Space Air Quality Inside Your Home

There are advantages and disadvantages in having a crawl space under your home. Advantages, perhaps, a slightly elevated home may be more attractive than a home on a slab. Plus, you can make repairs and modifications to plumbing, heating, and electrical services.

Disadvantages, a crawl space is an area that is never cleaned. Under the vapor barrier the humidity is always 100% so mold and bacteria are always present. Termiticides, other chemicals, even rodent droppings may be present, and odors and gases that emanate will migrate into the home's living space unless proper ventilation is installed. Whether on a slab or elevated, if radon is present, good ventilation is required.

There are several technologies on the market in regard to moisture control. One is encapsulation, sealing the crawlspace. Though this might lower humidity, it's costly and there is no dilution or replacement of stagnant, poor quality air. Again, if radon is present, ventilation is required.

Another technology is to install a dehumidifier in the crawl space. This can lower humidity, but again will not dilute or replace the stagnant air. Another point to think about is that the dehumidifier will be costly to operate. More importantly, using a dehumidifier requires you to close tightly the crawl space. Thus, the home's living space air quality is going to be lowered because the crawl space air is not diluted and replaced with fresh outdoor air.

Some systems use a dehumidifier control (dehumidistat) to operate a crawl space vent fan. This sounds like it's going in the right direction. However, the technology isn't quite right. Here's why. Suppose the outdoor air is getting worse (wetter). Though the dehumidistat control is in the crawl space, it will quickly recognize this wetter air condition and begin ventilation, even though ventilating is going to make crawl space wetter. Another problem with a dehumidistat control is that most of them are not made for the difficult environment of a crawl space, so their warranties are short, 30 days to 1 year maximum for the dehumidistat.

There is another system that uses special technology different from all the others mentioned above. This special technology makes a comparison of the actual moisture content of both the air inside the crawlspace and the outdoor air. The result is that it pauses and does not ventilate when bringing in outdoor air is going to make the space wetter. Then, as the outdoor air is getting drier and is able to improve the moisture and air quality in the crawlspace, then this ventilator moves a lot of air which dilutes and replaces stagnant air, ultimately improving your home's living space air quality.

This system, called the Smartvent, is made in the USA, is used from Florida to Alaska... San Diego to Nova Scotia.

This system is a proven system, and it is the only system to have undergone a year long test where crawl space humidity averaged 46%. Besides the unique technology this system employs, it also has the longest warranty of all ventilators, five years.

Crawl Space Dig Out: How to Turn Your Crawl Space Into a Basement

Outlined below are the most common 4 methods I have seen used in installing a vapor barrier. If you talk to different builders, you usually will end up with many different methods of installing a vapor barrier in a crawlspace. Here are the most common:

1. Pea Gravel on top of plastic vapor barrier - This has to be the all time dumbest thing I have ever seen, and yet it is probably one of the most common. I have had builders tell me that the plastic on the ground KEEPS ground water and moisture from coming up from the ground. Now if there is no moisture or water in the soil, this might be possible; but if that was the case there would be no need for the barrier in the first place. So here is the basic idea - ground floor (bottom) - plastic (middle) - 4" pea gravel fill (top). Once the crawl foundation is built, builders install a 4 - 6 mil plastic on the ground and dump about 4" - 6" of pea gravel on top of the plastic. Eventually, what always happens is that water comes in from the walls and the ground floor and ends up on top of the plastic. So what you end up with is a swimming pool liner that holds water in the gravel for prolonged periods of time. Nearly all the water and moisture in the gravel back fill has to evaporate into the structure. Another example of building practices and science turning a blind eye to crawlspaces for decades.

2. Vapor barrier on top of ground floor - By far the most common practice for installing a vapor barrier. A 6 mil polyethylene vapor barrier is placed over any ground floor. Here is the idea - ground floor (bottom) - plastic (top). The ground floor could be river rock, pea gravel, dirt floor, sand, etc. The seams are typically overlapped 6" - 12" and almost never taped. While this will temporarily stop some moisture evaporation, it does not seal out moisture from the internal perimeter wall where most water penetration occurs. Also moisture can come up from the seams, and the plastic is not durable enough to crawl on. It nearly always ends up with many punctures and holes in it.

3. Vapor barrier on bottom of floor joists - This is rarely seen, and usually only home owners attempt this. This is probably the method that accounts for more wood rot than any other method. If you are even thinking of doing this, quit thinking and call a professional to fix your crawlspace. Most crawlspaces are vented and the cooler surfaces such as duct work, pipes, and the floor will condensate in the summer. The plastic will trap the condensation up against the floor structure and mold and wood rot will occur. Good intentions do not always produce good results.

4. Vapor barrier fastened to sill plate - There is a new industry in crawlspace repair that encapsulates crawl spaces. The process of encapsulation is to install a heavy think plastic liner on the floor and up the foundation walls. The plastic liner is fastened and sealed to the foundation wall and all the overlapped seams are taped. Every potential gap or seam in the liner is meticulously sealed to prevent any moisture from evaporating. Then the vents are sealed in the encapsulation system to prevent hot humid air from entering in the summer. There is another system being sold and installed out there being represented as an encapsulation system, but is far from it.

This "other" system is a 6 mil plastic that is ran up the foundation walls and stapled to the sill plate. None of the overlapped seams are taped. It is basically a glorified vapor barrier on top of the ground floor being ran up the walls and stapled to the wood. They seal the vents without properly sealing the moisture from the ground floor or foundation walls. The problem with fastening plastic to the sill plate is that moisture will "wick" up the foundation wall, and moisture will absorb into the sill plate and floor joists. They are giving free access to all the moisture under the liner to rot the sill plates and floor joists. Not to mention that all the moisture will evaporate up through all of the seams that aren't taped and the plastic liner is only 6 mil and eventually will puncture and tear. Be very careful in the contractor you choose to properly encapsulate your crawlspace.

Radon gas makes its way through the earth, into the crawl space and the home’s living space. According to the U.S.E.P.A., radon gas is the number one leading cause of lung cancer in non-smokers.

Ignoring these various conditions is not recommended for both long-term health and energy usage. Fully encapsulating a crawl space – by both sealing and insulating – is a fully efficient measure in addressing such problems. It makes sense to maintain and improve the lower level area in order to maximize healthy living conditions and home resale value.

While there are several systems for encapsulating, a zero perm liner system that also insulates and reflects heat provides the most benefits. With a proper floor and wall liner, the area will not only be well insulated but will seal out moisture, bug infestation, and radon gas. Other components to look for in a system include a radon gas-dispersing drain fabric, a radon gas ventilation pipe, and a ceiling heat shield.

A complete system with all of the above components will allow any soil gasses – including radon gas – that naturally occur under the liner system, to wick through the drain fabric and escape out through the ventilation pipe. While improved indoor air quality is the primary benefit of a sealed and insulated crawl space, the homeowner will also appreciate a bright, clean, and dry storage area; the ridding of musty smells; less energy usage; and tax credits. Contractors encapsulating crawl spaces will have more to offer to their clients when they can assure the peace of mind with improved indoor air quality.

Crawl Space Encapsulation - Eliminate Musty Smells DIY - Mold Encapsulation

The single best thing you can do to eliminate moisture and odors coming from the crawlspace is to apply a heavy sheet of plastic. Plastic wrap comes in clear or black and in different thicknesses. Purchase either color and with a thickness of at least 6 mil or better yet 10 mil.

Roll out the plastic so that all of the crawlspace floor is completely covered with plastic. When you have to cut the plastic to go around something, be sure to cover the cut with additional plastic or lap the original layer over the cut out. It's OK to use duck tape on the plastic vapor barrier as well. Just be sure to not have any voids in the plastic where moisture and odors can still get through.

The walls of the crawlspace should be covered as well to better eliminate moisture concerns as they can harbor condensation, a major source of moisture issues. Just roll out extra length of plastic so that you can run it up the crawlspace wall and using the stapler, tack along the ledger board located just above the concrete block or poured wall.

If you eliminate odors, moisture from the crawlspace and other undesirable elements coming from the ground beneath your home, your family will be living in a much healthier environment.

Although this task can be accomplished by yourself, it will be much easier if you can get a buddy or helper to go into your crawlspace and aid in the rolling out of the plastic barrier.

6 mil plastic is fine, however, if you can find thicker plastic (greater than 6 mil) then it will be much harder to rip or tear as you move along the crawlspace.

Basement Finishing Ideas For The Do-It-Yourselfer

A basement is prone to all types of foundation issues like, cracks in the interior and exterior walls, leaks, soil pressure, excessive moisture, seepage and dampness. These problems get worse over time and cause long term damage to your home, if left untreated. In order to enhance the structural integrity of your home, it is very important to take professional help for basement foundation repair. A professional will ensure that the problem is resolved efficiently.

Many properties experience foundation issues at some or the other time and it is important to know how severe the problem is to look for a treatment that offers a permanent solution. A basement foundation repair can be easily done if you have basic information about the ways to handle such repairs. There are various methods of repairing the foundation of a home. If there is some serious damage, it is advisable to take professional help. For general maintenance, you can either go for mortar application or patching repairs.

Some indications which suggest that you should go for basement foundation repair includes:

- Uneven Floors
- Water collection
- Cracks at entry or exit doors
- Doors not closing or opening properly

Cracks are the most common type of foundation maintenance issues. They are usually found in older basements and are caused due to the changes in the soil below the basement. Shallow foundations are more prone to cracks.

How To Clean Cracks

Once you have identified cracks in the foundation, you need to first clean them comprehensively. Cleaning is important as it not only helps in knowing the type of repair required, but also helps in proper application of the adhesive material. You can use a chisel to remove loose fragments from the cracks and then inspect it to find the right repair method.

If the cracks have just begun to show, you can use either hydraulic cement or Portland mortar to seal the cracks. These materials come with easy to follow instructions and can also be used to resolve any visible unevenness along the basement floor.

If your basement foundation is facing standing water problem, the moisture seepage can cause cracks in the drywall. To patch the leaky spots is the most effective solution for dealing with this problem.

To ensure that repeated basement foundation repairs are not needed, the groundwater should be directed away from the foundation.

A professional basement foundation repair company can be hired to repair foundation cracks, basement walls, stabilize the foundation, install foundation guard, repair eroded, bowed or unstable walls and remove mold problems. A strong basement foundation increases the value of your home.

The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in East Knoxville Knoxville  don’t think twice about their crawl space unless they have to make repairs to plumbing, heating ducts or house wiring. While often thought of as no more than a storage area, it also has a tremendous impact on the overall indoor air quality of the entire home.

The Best Clean Crawl Space In East Knoxville TN

By default, the air quality of a crawl space is typically poor. Mold, mildew, radon gas and poor energy efficiency all create several problems.

With homeowners more concerned about their home’s indoor air quality, the encapsulating of crawl spaces has become a popular solution for such problems.

A damp crawl space creates a safe harbor for harmful molds, in addition to dust mites, termites and other bugs that can infest the home.

Crawl Space Vapor Barriers

There are advantages and disadvantages in having a crawl space under your home. Advantages, perhaps, a slightly elevated home may be more attractive than a home on a slab. Plus, you can make repairs and modifications to plumbing, heating, and electrical services.

Disadvantages, a crawl space is an area that is never cleaned. Under the vapor barrier the humidity is always 100% so mold and bacteria are always present. Termiticides, other chemicals, even rodent droppings may be present, and odors and gases that emanate will migrate into the home's living space unless proper ventilation is installed. Whether on a slab or elevated, if radon is present, good ventilation is required.

There are several technologies on the market in regard to moisture control. One is encapsulation, sealing the crawlspace. Though this might lower humidity, it's costly and there is no dilution or replacement of stagnant, poor quality air. Again, if radon is present, ventilation is required.

Another technology is to install a dehumidifier in the crawl space. This can lower humidity, but again will not dilute or replace the stagnant air. Another point to think about is that the dehumidifier will be costly to operate. More importantly, using a dehumidifier requires you to close tightly the crawl space. Thus, the home's living space air quality is going to be lowered because the crawl space air is not diluted and replaced with fresh outdoor air.

Some systems use a dehumidifier control (dehumidistat) to operate a crawl space vent fan. This sounds like it's going in the right direction. However, the technology isn't quite right. Here's why. Suppose the outdoor air is getting worse (wetter). Though the dehumidistat control is in the crawl space, it will quickly recognize this wetter air condition and begin ventilation, even though ventilating is going to make crawl space wetter. Another problem with a dehumidistat control is that most of them are not made for the difficult environment of a crawl space, so their warranties are short, 30 days to 1 year maximum for the dehumidistat.

There is another system that uses special technology different from all the others mentioned above. This special technology makes a comparison of the actual moisture content of both the air inside the crawlspace and the outdoor air. The result is that it pauses and does not ventilate when bringing in outdoor air is going to make the space wetter. Then, as the outdoor air is getting drier and is able to improve the moisture and air quality in the crawlspace, then this ventilator moves a lot of air which dilutes and replaces stagnant air, ultimately improving your home's living space air quality.

This system, called the Smartvent, is made in the USA, is used from Florida to Alaska... San Diego to Nova Scotia.

This system is a proven system, and it is the only system to have undergone a year long test where crawl space humidity averaged 46%. Besides the unique technology this system employs, it also has the longest warranty of all ventilators, five years.

5 Helpful Tips For When it is Time to Encapsulate Your Crawl Space

Many homeowners try to cut costs and increase their home's comfort level by installing a crawl space vapor barrier. This will instantly make your home healthier for you and your family, and prevent moisture damage, mold, mildew, foul smells and odors.

Most homeowners tend to look at their crawl space as separate space from their home, but in reality, the two are one. Water vapors that surface from the ground are continuously entering, creating undesirable conditions for you, your family, and your home.

Purpose

The purpose of a crawl space vapor barrier is to stop moisture and wetness from entering and affecting the floor and walls of your basement. Moisture tends to flow from warmer to colder spaces.

Many homeowners don't realize the importance of the proper installation, in order to keep moisture and water vapors from getting in the walls and floor of your basement-- condensation can lead to expensive structural damage. Also, if you can help control the moisture and dampness, you can greatly reduce the amount of energy required to cool and heat your home.

Preparation

When considering the installation of a vapor barrier, take into consideration two spaces in your home; the crawl space and the attic. Humidity tends to build in the walls of both these areas causing mold, mildew and dry rot. This can cause severe health issues for adults and children, especially for those with asthma, breathing difficulties, and allergies. In addition, it can cause severe structural damage to your home.

Some homeowners think that because they insulate the floor joists there is no need to do any additional work, but these items do not serve the same purpose!

Tips for Installation

One of the most popular do-it-yourself vapor barrier products is polyethylene, or plastic sheeting. This plastic sheeting comes in various thicknesses; 4mm, 6mm and 10mm.

With today's technology, this product is made from a high quality material, resistant to rips and punctures. Always check the soil so there aren't any objects or materials that may damage the lining. The slightest puncture, rip or tear could compromise the entire system.

Always, make sure the space is dry before you begin any repairs. To remove the moisture, you may need a dehumidifier.

Overlap the barrier a minimum of 12 inches on the side walls. Be sure it is tight. Use furring strips and masonry nails to firmly secure the lining then caulk along the joints.

Seal all the seams with a heavy duty tape. However, it is recommended not to use tapes that are not specially designed for sealing vapor barriers. When working in the basement you will be forced to contend with pipes, make the proper cuts and seal securely with tape.

The completion of your crawl space vapor barrier will be the best investment you can make in your home.

The Three Basic Types of Home Foundations

Before you sign that independent contractor agreement, consider this:

You're hungry, and you and your special someone decide to eat out. You drive down the road and find two restaurants standing next to other. From the outside, they seem about the same with one significant difference: the parking lot in front of one restaurant is nearly empty. The other restaurant? Packed! The lot is nearly full, and there's a crowd at the door. Through the restaurant windows you see smiling faces and filled tables. You pull in, and when you're greeted at the door, you're told there will be a 45 minute wait for your table. Will you leave the restaurant and go next door to the one that can serve you immediately? Isn't there a reason the other one is empty?

If you're looking for a basement waterproofing contractor to work on your home, you've got more than a bad taste in your mouth to worry about. Symptoms of a wet basement include headaches, moldy basement carpeting, wet drywall, ruined personal possessions, spreading mold, smelly basement syndrome, fatigue after hours of cleaning, and an exhausted bank account. Don't take chances on the empty business- if you reach a basement waterproofing company with a long line, there must be an awful lot of people who think they're worth the wait.

If you're not sure if the basement waterproofing contractor you've decided to work with is the best in the business, there are many ways to check out their reputation. Visit the local Better Business Bureau web site and check out their reputation- any complaints registered with them will be public for three years. Compare them with other local dealers, taking into account the size of the businesses and how many jobs has been completed for each.

It's also a good idea to check the contractor consumer web site such as Yelp! Or Angie's List. If the local contractor is registered, then reviews, company information, and ratings for quality and service will be clearly laid out as well as anecdotal accounts created by customers of this contractor will be available. There's a lot of ways online to have a customer's feelings be heard nowadays.

As a final way to check on your basement waterproofing contractor, contact them and ask for references. Many contractors will collect references from previous jobs and will be able to connect you with testimonials and contacts that will be able to give you a personal account of the quality of their service. However, whether you check with the Better Business Bureau, Angie's List, or you're checking up on references, you'll be gathering information directly from former customers about what these basement waterproofing contractors are all about.

Crawl Space Vapor Barriers

There are three basic types of foundations in use today in the construction of a home.

Slab Foundations

A slab foundation is a foundation built directly on the soil with no basement or crawl space. Slab foundations are common in areas where soil conditions are not suitable for a basement, and are the most common foundation found in warmer areas such as Florida, Arizona, California and Texas, or anywhere where the depth between the soil and stable underlying rock is very shallow. Slabs are the quickest and cheapest foundation because they require less labor, skill and materials cost. They consist of a concrete slab that is typically 6 to 8 inches thick. Embedded within the slab is a grid of supporting ribbed metal rods known as "rebar." Even in locations where basements are prevalent, slab foundations are typically laid to serve as the base for structures like garages, pole barns, and sheds. Slabs are the least expensive of the three main foundation types but provide no storage or utility space, as the home actually sits directly on a large platform of solid concrete. Slabs have the disadvantage of being difficult and expensive to repair when they settle and crack, and plumbing lines that protrude from the soil upward through the concrete can also be expensive to repair. In areas where the underlying soil is thick or prone to excessive expansion and contraction, cables are embedded which can be tightened to provide better horizontal support and minimize the width of cracks.

Crawl Space (Pier and Beam) Foundations

A pier and beam foundation consists of either vertical wood or concrete columns (piers) that support beams or floor joists above the ground. The areas between the soil and the bottom of the house floor is known as the crawl space. These foundations are built either at ground level or over a shallow excavation that varies in depth, but is commonly about 36 to 40 inches deep. The best crawl space foundations have a load-bearing concrete perimeter wall and concrete or steel piers, both having footings below the freeze line of the soil, along with a good barrier over the soil to keep moisture under control. Less expensive versions have no load-bearing perimeter walls, piers with shallow footings, and no moisture barrier at all over the soil. Crawl spaces that enclosed by a wall or by skirting must have vents on every side to allow air to circulate and help keep the soil dry under the home. These vents must be configured to prevent the entry of rodents and snakes. Crawl space foundations are most often used in areas where there is heavy clay content in the soil that can severely damage (crack) slab foundations, or in waterfront or flood prone building sites where the necessary floor height to prevent water penetration of the living space must be higher than a slab can normally provide. The primary advantages of crawl space foundations are that plumbing lines are readily accessible for repairs, and foundation settlement problems are easier and less expensive to correct than with slab foundations. A primary disadvantage occurs when these foundations are not properly maintained or are constructed without adequate ventilation, allowing water or pests to cause damage. Crawl space foundations without adequate insulation applied to the bottom of the house floor can be very energy inefficient in a cold climate.

Basement Foundations

A basement is a type of foundation which includes an accessible space between the soil and the bottom of the first floor of a home. This foundation provides living space below the home, below the ground elevation. It is basically a slab foundation with walls and a floor. Basements are most often built in cold weather climates such as the Northeast, Midwest and Rocky Mountains, and in places where the cost of excavation is not prohibitive. Basements start with a hole approximately 8 feet deep, however, some homeowners will opt for a 9 or 10 foot deep basement wall to increase height and volume of useable space. The floor and walls are built, then the house itself is built over that. Basement foundations have the advantage of providing useful space for utilities, mechanicals systems, and storage not available in the previous two types of foundations. The primary disadvantage of basements is that because they are mostly below ground level, they are vulnerable to leakage, mold formation, and flooding. Basements in wet climates must always have a working drain and pump in the floor to combat flooding.

How To Protect Your Health And Get Rid Of Awful Smells With Crawl Space Encapsulation

There are advantages and disadvantages in having a crawl space under your home. Advantages, perhaps, a slightly elevated home may be more attractive than a home on a slab. Plus, you can make repairs and modifications to plumbing, heating, and electrical services.

Disadvantages, a crawl space is an area that is never cleaned. Under the vapor barrier the humidity is always 100% so mold and bacteria are always present. Termiticides, other chemicals, even rodent droppings may be present, and odors and gases that emanate will migrate into the home's living space unless proper ventilation is installed.

Radon gas makes its way through the earth, into the crawl space and the home’s living space. According to the U.S.E.P.A., radon gas is the number one leading cause of lung cancer in non-smokers.

Ignoring these various conditions is not recommended for both long-term health and energy usage. Fully encapsulating a crawl space – by both sealing and insulating – is a fully efficient measure in addressing such problems. It makes sense to maintain and improve the lower level area in order to maximize healthy living conditions and home resale value.

While there are several systems for encapsulating, a zero perm liner system that also insulates and reflects heat provides the most benefits. With a proper floor and wall liner, the area will not only be well insulated but will seal out moisture, bug infestation, and radon gas. Other components to look for in a system include a radon gas-dispersing drain fabric, a radon gas ventilation pipe, and a ceiling heat shield.

A complete system with all of the above components will allow any soil gasses – including radon gas – that naturally occur under the liner system, to wick through the drain fabric and escape out through the ventilation pipe. While improved indoor air quality is the primary benefit of a sealed and insulated crawl space, the homeowner will also appreciate a bright, clean, and dry storage area; the ridding of musty smells; less energy usage; and tax credits. Contractors encapsulating crawl spaces will have more to offer to their clients when they can assure the peace of mind with improved indoor air quality.

A Vapor Barrier in Your Crawlspace is a Healthy Addition For Your Family

In recent years, the idea of indoor air quality control has become a bigger concern to the basement waterproofing industry. When I began working with the industry over 20 years ago, the idea of basement waterproofing was exclusive to the controlling of and prevention of water seepage and flooding. With homeowners becoming more aware of radon gas infiltration, moisture and mildew, and other soil gases, waterproofers have the perfect opportunity to better serve their customers by addressing such needs.

Musty smells, moisture and radon gas - all common problems in a basement and/or crawl space, are solvable by enacting some of the most basic waterproofing techniques. Improving indoor air quality, beginning from the basement and/or crawl space will impact the air quality of the entire home. Over 50 percent of the air that circulates through the home's living space originates from the basement and or crawl space. When the air quality of the basement or crawl space is poor, chances are, the entire home's air quality is poor or soon will be.

One of the first measures a contractor can do to address such concerns is by applying a sodium based silicate spray onto the basement's walls and floors. Such a spray typically reacts with the concrete's free lime, resulting in the formation of an expanded crystalline structure beneath the surface. The application of a deep-penetrating concrete sealer stops water vapor and radon gas from permeating the porous surfaces. This allows the concrete to become dense, increasing its resistance to various vapors and gases. Such sealants usually can be applied with a low-pressure hand sprayer.

When applying the right sodium based silicate spray, some of the additional advantages may include the reduction of spalling from freeze and thaw cycles; improving a concrete structure's resistance to most soils, acids, oils and salts; and protecting against efflorescence and leaching - specific results will vary pending the type of spray that is applied.

It is recommended to clean the concrete surface prior to application. Any dirt, oil or foreign substances may hinder the effectiveness of the spray. After such a spray is applied, the surface should be flushed with water before drying.

The prevention of moisture and soil gases permeating through concrete surfaces goes a long way in reducing the growth of mold and eliminating the musty smell that often plagues a basement and/or crawl space. Waterproofing contractors have always been called to address immediate water problems for the short-term; with indoor air quality control, contractors can now offer a viable long-term service that provides their customers with the ultimate peace of mind.

Nobody loves to pay more! Are you stuck with paying prohibitive energy bills during the colder seasons? If your answer to the above question is yes, then you need to really consider giving your house a dose of crawl space insulation. This will definitely save you some amount in energy bills and give you a load of other varied benefits. For the optimal heat maintenance, consider insulating more than just the walls of your house. The attic, crawl space and basement of your house will benefit you more if they were insulated and checked.

It's known that the such spaces especially contain foundational vents and gaps that let the wiring and the pipes and ducts in. If these are not sealed accordingly, they could lead to air leaks and insulation problems. These spaces can let in unconditioned air from the outside leading to health problems and problematic house heating. You need your rooms to stay cooler and have lesser of health problems, don't you?

So what are the benefits of the insulation?

· More Comfort

This is the major reason that you should be thinking of insulating your house's crawl space, if you have not yet done so. Insulating your house ensures comfortable internal temperatures both in the summer and winter seasons. If you are preserving things in your crawl space, having a space vapor barrier installed and enforcing it with the space encapsulation might make the temperature standard.

· It Also Saves Energy

A house with correctly installed space insulation, space vapor barrier and similar encapsulation keeps the inside air separate from the outside air. This can save you from costly energy bills at the end of the month. Un-insulated crawl spaces can become increasingly drafty and let large amounts of outside air inside the house. Un-insulated spaces also allow the air inside the house to escape out. This can lead to high costs of constantly trying to standardize the air in your house.

· Moisture Control

When coupled with space vapor barrier, crawl space insulation controls the moisture level in your crawl space. This improves the effectiveness of air sealing and leads to general energy efficiency. Uncontrolled moisture levels in the crawl space leads to the growth of mold and the peeling of paint from the inside walls of your house. This can make you waste money on unforeseeable repair and maintenance costs.

Choosing the Right Insulation Service Providers

By having the right space insulation installed in your house you stand to reap a lot of benefits. It is however recommended that you use space insulation experts to get the best services.

The best space insulation companies will do a thorough inspection of your house to identify all the spaces that need insulation. They may also recommend that you add space encapsulation and space vapor barrier for the most optimal results. After all, you do need a home where you can live in comfort.

Give yourself the home that you will love always!

Though process may sound expensive and unattainable, it is important to keep the benefits that you stand to reap from the crawl space insulation in mind. You should also let the contractor know of your budget allocations well ahead of time. And don't forget to appreciate the great house that you will have after all is done!

The Best Crawl Space Repair In Hardin Valley TN

By default, the air quality of a crawl space is typically poor. Mold, mildew, radon gas and poor energy efficiency all create several problems. The air that circulates within it eventually makes its way up through the living space. Scientific studies show that up to 50% of living space air originates from the lowest level of the home. With homeowners more concerned about their home’s indoor air quality, the encapsulating of crawl spaces has become a popular solution for such problems.

A damp crawl space creates a safe harbor for harmful molds, in addition to dust mites, termites and other bugs that can infest the home. The presence of excessive moisture will also create a serious problem with the probability for the wooden structure of a home to deteriorate. Crawl space vents pose a further problem. While believed to be a solution to moisture problems, they, unfortunately, make the problem worse. As it turns out, the vents allow cold air and moisture in, which rises into the living area and therefore decreases the heating efficiency of the entire home.

Another all-too-common problem associated with crawl spaces is radon gas. Though it cannot be seen, smelled or tasted, radon is a radioactive gas that can contribute to poor health, including cancer. Radon gas makes its way through the earth, into the crawl space and the home’s living space. According to the U.S.E.P.A., radon gas is the number one leading cause of lung cancer in non-smokers.

Crawl Space Repair Without a Fan or Vent

1) Lower your energy costs: A crawl space encapsulation insulates the walls of your crawl space and conditions the air under your home. This results in a 10% to 20% annual savings on your power bill. Encapsulation is one of the few home repairs that pay for itself!

2) Increased home comfort: By conditioning the air in your crawl space your floors will not be cold in the wintertime. This is especially nice for hardwood floors and tile bathrooms. It also keeps your home from feeling humid and stuffy in the summertime.

3) No more musty odors: A crawl space encapsulation eliminates moisture under your home. This means no musty odors being pumped into your home through the air conditioning unit.

4) Increase the air quality of your home: By eliminating moisture under the house, you are no longer getting humid unconditioned air into your home. Encapsulation promotes air circulation throughout the home.. If your air conditioner is located under the house, it is no longer pumping mold spores throughout the home.

5) Air Conditioner lasts longer: Another way encapsulation saves you money is by improving the longevity of your heating and cooling equipment. Humidity increases the load on your air conditioner and causes trunk lines and air ducts to rust.

6) Minimize Repairs: Crawl space encapsulation eliminates moisture under your home. This moisture is the source of many problems from insulation damage, mold and mildew outbreaks, structural damage, and equipment damage from rust.

7) Eliminate insect infestations: By reducing moisture you eliminate a key ingredient that insects such as termites need to survive. No longer will your crawl space be a conducive condition to harbor ugly creepy crawlies in your home.

8) Extra storage space: Most people do not store much in the crawl space because it gets damp, rusts and damages about everything. An encapsulated crawl space becomes a moisture free environment that is perfect for storing anything and everything. Adding 1000 sq ft to 2000 sq ft of storage space always helps.

9) Increase the value of your home: An encapsulation system greatly increases the value of your home. It also makes your home easier to sell. Your home has no moisture issues for the home inspector to find and you have proof of energy efficiency and the lower energy bills your home produces.

10) Tax incentives and rebates: The federal government offers tax rebates for insulation products that improve the energy consumption of you home. Local power companies sometimes offer rebates on your power bill to improve the energy efficiency of your home.

Crawl Space Encapsulation Systems DIY

Many homeowners try to cut costs and increase their home's comfort level by installing a crawl space vapor barrier. This will instantly make your home healthier for you and your family, and prevent moisture damage, mold, mildew, foul smells and odors.

Most homeowners tend to look at their crawl space as separate space from their home, but in reality, the two are one. Water vapors that surface from the ground are continuously entering, creating undesirable conditions for you, your family, and your home.

Purpose

The purpose of a crawl space vapor barrier is to stop moisture and wetness from entering and affecting the floor and walls of your basement. Moisture tends to flow from warmer to colder spaces.

Many homeowners don't realize the importance of the proper installation, in order to keep moisture and water vapors from getting in the walls and floor of your basement-- condensation can lead to expensive structural damage. Also, if you can help control the moisture and dampness, you can greatly reduce the amount of energy required to cool and heat your home.

Preparation

When considering the installation of a vapor barrier, take into consideration two spaces in your home; the crawl space and the attic. Humidity tends to build in the walls of both these areas causing mold, mildew and dry rot. This can cause severe health issues for adults and children, especially for those with asthma, breathing difficulties, and allergies. In addition, it can cause severe structural damage to your home.

Some homeowners think that because they insulate the floor joists there is no need to do any additional work, but these items do not serve the same purpose!

Tips for Installation

One of the most popular do-it-yourself vapor barrier products is polyethylene, or plastic sheeting. This plastic sheeting comes in various thicknesses; 4mm, 6mm and 10mm.

With today's technology, this product is made from a high quality material, resistant to rips and punctures. Always check the soil so there aren't any objects or materials that may damage the lining. The slightest puncture, rip or tear could compromise the entire system.

Always, make sure the space is dry before you begin any repairs. To remove the moisture, you may need a dehumidifier.

Overlap the barrier a minimum of 12 inches on the side walls. Be sure it is tight. Use furring strips and masonry nails to firmly secure the lining then caulk along the joints.

Seal all the seams with a heavy duty tape. However, it is recommended not to use tapes that are not specially designed for sealing vapor barriers. When working in the basement you will be forced to contend with pipes, make the proper cuts and seal securely with tape.

The completion of your crawl space vapor barrier will be the best investment you can make in your home.
