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.

The Best Wet Crawl Space In East Nashville 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.

The Three Basic Types of Home Foundations

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.

A Closed, Sealed Crawlspace - What a Really Bad Idea

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.

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

For many homeowners, the first thought in their mind when they consider installing a crawl space waterproofing system is, "But I don't go down there! Why on earth would I do that?"

Good question! And there's a great answer. While you probably don't think about your crawl space, and you may have never even seen your crawl space, it's part of your home. What happens to it has surprising effects the rest of your house.

Water can enter into your crawl space in three different ways: through the earth (or concrete) around your home, from a plumbing leak, or through the air entering your crawl space vents. Whether this moisture enters as humidity or as an all-out leak, a wet crawl space means a headache for you. Moisture collects in anything organic - including wood floorboards, support beams, and some types of crawl space insulation. As the wood swells and warps with moisture, there are nasty results: mold, rot, mildew, bacteria, and dust mites.

What you have beneath your house is no longer a crawl space. It's a habitat. The area is filled with humidity, mold spores, and dust mites. All too soon, mice, rats, snakes, and vermin will take up residence- living and dying in the dark, wet area beneath your home. And there's nothing more attractive to a termite colony looking for a new place to live than all that damp, rotting wood!

Ignore the monster lurking below while you can, but remember that even before your rotting floor and support beams are significantly damaged, you're already being affected. Warm air in your home exits the home through your upper levels, and crawl space air is sucked up into your home. As it's pulled up, nothing is stopping the humidity, mold spores, dust mite waste, and odors coming up with it. In the summer, your air conditioners will be working overtime to remove this humidity. During the winter months, cold air vented into the home hammer away at anything it can reach- including the water heater, hot water pipes, and heating ducts.

In a vented crawl space, insulation is a Catch-22. If you don't have crawl space insulation, then there's no line of defense keeping humid summer air and cold winter air away from your floorboards. If you do have crawl space insulation, then moisture and mold can saturate the material, weighing it down and causing it to collapse on to the floor. If it's wet or lying on the ground, what can it do for your home?

The first step to solving a crawl space moisture problem is to remove any standing water issues. Left in your home, it will add humidity to the home, encourage mold and mildew, and bring pests into the room while it stagnates. It simply has to go.

If your crawl space has pooling water at any time, a reliable cast-iron crawl space sump pump is the best option. Water can be directed to the sump pump via a drainage swale, or in some cases, a modern French drain system.

Humidity pours into your house through the crawl space vents, and the damp earth and cement around your home will soak up water like a sponge, releasing water vapor into the area. Cut this problem off at the source by sealing off all crawl space vents and installing a crawl space vapor barrier. Avoid cheap solutions- the kind of product you're looking for should be strong and durable- at least 20 mil thick. A quality crawl space vapor barrier will allow access for you and service workers without tearing your line of defense. Crawl space vapor barriers should also be flexible and resistant to punctures and tears, and a bed of gravel should be laid underneath to allow water to pass underneath.
