The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Old Hickory 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 Crawl Space Insulation In Old Hickory 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.
DIY Basement Foundation Repair
When a home has sagging floors, the signs many be obvious, or they may be quite subtle. Here are some questions a home owner can ask himself to glean whether or not sagging floors is a real problem for his home.
- Does it seem that the home's floors sag towards the middle of the room?
- Does furniture slide away from walls and creep towards the middle of the room?
- Are there gaps in between the home's floor and baseboards?
- Do the home's cabinets rattle when someone walks through a room?
Many homeowners ask what causes sagging floors. Sagging floors can be caused by several factors:
- A shifting foundation beneath the home
- Floor joists in the home that have been weakened by excessive moisture
- Excessively large of spans between floor joists without enough support
- Excessive or heavy loads (furniture, gym equipment, granite) in the room(s) above a home's crawl space
- The use of temporary shims to fill flooring gaps; shims settle and shift out of place over time
The solution is more simple than it might seem! Adjustable steel crawl space supports are an economical and quick solution that can withstand the test of time. These adjustable posts are a permanent solution that work by transferring the weight of the home's flooring structure to more competent soils beneath the home. Many homeowners will attempt a do-it-yourself solution for sagging floors by inserting wooden shims to prop the floor back up. This is only a temporary band-aid and does not address the fundamental issues with the flooring structure. Shims made from wood, which are often a homeowner's first solution for the repair, can slip, shift and rot over time.
By contrast, the adjustable steel supports can be installed quickly (in less than one day), with little to no disturbance done to the property. Also, they are able to provide adequate support exactly where it is needed most. As the name implies, the supports can be adjusted in order to provide the exact amount of support needed, and they are fully compatible with a crawl space encapsulation system, should a home need that as well.
Crawl space repair is a common procedure done in many homes all over America. Unfortunately, many homeowners are unknowingly choosing temporary and insufficient means to support their homes, thinking that the professional and permanent solution will be too costly, disruptive, and time consuming. Adjustable steel crawl space supports can fix a home's sagging floors permanently without disrupting the family, the yard, or the wallet too much!
Improving a Home's Indoor Air Quality by Crawl Space Encapsulation
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.
