Clean Crawl Space East Nashville TN

The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in East Nashville Nashville  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.

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.

Basement Finishing Ideas For The Do-It-Yourselfer

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.

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

Crawl spaces are inherently dirty smelly places that can contain all types of unwanted odors from mold & mildew to urine & feces. Some areas of the country can even have soil underneath the home with odorless, harmful gases like radon gas. I'm a big believer that the best long-term solution to solve these problems is to encapsulate the air underneath the home with a liner system. It is a inherently impossible to keep rodents, bugs and mold out of the area underneath the home since the soil is exposed - but it is relatively simple to create a barrier between the home and crawl space the keep out all these unwanted nuisances.

I had a very nice lady write me the other day telling me about this house she had just purchased that formerly had many cats living in the crawl space and they left behind the smell of a giant litter box underneath her home. The odors were coming up through the wooden floor and creating a very fowl smell in the house. She told me she tried all different solutions: spreading baking soda, spraying an enzyme treatment originally intended for carpets & laying down new top soil - needless to say none worked. I wrote her back, apologized for her wasted time and suggested that she treat her crawl space like a wild beast that you can't defeat, only contain. She took my advise, installed a crawl space encapsulation system and the smells immediately went away.

Permeability Rating

Encapsulation systems are rated by permeability - 0.000 is the best, normal plastic is 0.01 and wood is 0.2. To stop all smells, moisture and gases look for an encapsulation liner system with a 0.000 permeability rating. A zero perm liner will also completely weatherize the crawl space and save on energy bills since the outside air won't be able to leak into the home.

Thin Liners Don't Encapsulate the Crawl Space

I can't tell you how many times I've received a call or been sent an email from a homeowner telling me how they went to Home Depot, bought a liner system as thin as a trash bag, spent an entire weekend installing it then didn't solve their problem. Cheap store bought liners are typically 6-12 mil, 0.01 permeability and even new they don't stop gases like Radon - they are also easily chewed through by bugs and rodents leaving the crawl space a year later leaking air like a sieve.

What to Look for

40 - 60 mil thickness, 0.000 permeability and antimicrobial so mildew can't grow on the liner. Encapsulation systems don't need a contractor to install (although trust me they won't tell you that). Look for the Energy Star Rated logo.

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

I've been in the crawl space business for 15 years and I've seen almost every system you could imagine - from spray foams to concrete to thin plastic sheets. Some are better than others, but the only real way to encapsulate the area beneath your home is to install a liner with zero permeability.

What is Zero Perm?

Zero Perm means just that absolutely no water, moisture, radon gas or odors will penetrate through it. Tests have to show 0.000 penetration of Hydrogen gas (the smallest gas molecule) through the membrane. The whole idea of spending the money to encapsulate the crawl space or basement is to STOP water, moisture, radon gas and any unpleasant odors. Liners that are 6, 12 and 20mil thick are NOT Zero Perm and will still let in harmful gasses as well as letting in moisture that will only continue to feed the mold and bugs that try to get in your home.

What Else Should I Look for in a Liner?

If you are going to spend the time & money to install a crawl space liner look for more benefits as well as zero permeability. Look for liners that are

- Energy Star Rated to get a 30% Tax Credit back on your purchase
- R Value of 5 to add insulation & increase your heating/ cooling efficiency
- Reflectivity value of 97% to prevent radiant heat loss
- Class A / Class 1 fire rating

Homeowners all over are finding that improving the homes they have is more cost effective than buying new. Some homeowners like the fact that they can save money by doing the work themselves and some still prefer to have someone else do the installation. Either way, using a Zero Perm, Energy Star Rated encapsulation system is a great way to pre-finish a basement or any area underneath your home.

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

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.
