Crawl Spaces in Nashville 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.
Crawl Space Remediation Nashville
I’ve been doing crawl space encapsulation in Nashville 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.
Improving a Home's Indoor Air Quality by Crawl Space Encapsulation
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.
Crawl Space Supports
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.
