Crawl Spaces in Tennessee 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 Tennessee 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.
5 Reasons Why Basement Waterproofing is Essential
Installing a crawlspace vapor barrier is not rocket science. It is not physically difficult. Whether installing a quality vapor barrier in a vented crawlspace or doing a complete crawlspace encapsulation, it only takes a little time, a little patience and a willingness to crawl around on your hands and knees for a couple of days.
Where to Buy a Crawlspace Vapor Barrier
There are many places to purchase a crawlspace vapor barrier. An on-line search will provide contact information many retailers. And the products they offer vary from inexpensive clear plastic to woven and coated fabrics much like swimming pool liners. The inexpensive liners can also be purchased from many hardware stores and home centers.
What Vapor Barriers Are Available
The inexpensive vapor barriers will do the job but it's been our experience that they tear easily, don't stay in place, and become brittle and crack after four to five years. But they are inexpensive.
The alternative is to spend a couple times more initially and purchase a product with a twenty five year warranty. The reinforced or woven products require no more time to install than the inexpensive shorter-lived products.
The real question is whether an installer wants to spend a couple of days crawling around in a damp crawlspace every four or five years, or wants to spend a little more initially and have an installation that is maintenance-free and will last for decades. Personally, it makes more sense to me to do it right the first time and be done with it.
Installing the Vapor Barrier
Whether doing a full crawlspace encapsulation or simply installing a vapor barrier in a vented crawl space, the installation of all products have a lot in common.
First, the floor needs to be completely covered, with all seams overlapped 6" to 12" and sealed with tape. While duct tape is a wonderful product with countless uses, it does not do a good job sealing the seams of a vapor barrier. A quality, water-proof vinyl tape designed specifically for sealing the seams is recommended.
Wrapping the Crawlspace Piers
Second, the floor material needs to be sealed around all the foundation supports. Whether steel posts or concrete block piers, it is necessary to prevent the migration of water vapor from around the foundation supports. This is usually done by wrapping the piers - sealing the piers with the vapor barrier 6" to 12" up from the floor. This provides a sealed pier to which the floor material can be sealed to using seam tape.
Wrapping the piers can be a little problematic. No safe, nonflammable, nontoxic construction adhesive is effective with the available materials except for a newly developed, patented proprietary wall and pier liner. The vapor barrier is typically applied to the piers using a combination of tape, mastic, caulk, and mechanical fasteners. The mechanical fasteners require that holes be drilled into the piers using a masonry bit and hammer drill. This adds exponentially to the installation labor.
The patented wall and pier liner can be applied to most any surface using a low VOC and nontoxic construction adhesive. Being low VOC and nontoxic, it is nonflammable and safe to use in the confined area of a crawlspace. It can be safely installed in a fraction of the time. It is the only material of its kind and can be ordered from it manufacturer.
Sealing the Crawlspace Walls
Finally, regardless of whether you're installing a vapor barrier in a vented crawlspace or doing a full encapsulation, it is necessary to seal the floor material to the crawlspace walls. Most experts agree that this is a vital step for a well installed barrier or encapsulation.
If installing a vapor barrier, the floor material should be sealed to the wall 6" to 12" above the outside grade. Like wrapping the piers, most companies recommend the tape-caulk-mechanical fastener combination. The mechanical fasteners should be placed every two to three feet long the perimeter of the crawlspace. If taking this approach, be sure to use a respirator as concrete dust can cause severe respiratory problems.
If doing a full encapsulation, the entire wall, a minimum of three inches down from the sill plate to allow for a pest control inspection, should be sealed. Enough floor material can be purchased to extend up the walls or, the method we've found easiest, the wall is covered and sealed with a wall liner and the floor material is sealed to the wall liner using seam tape. Regardless of which method you use, the vapor barrier must be securely attached and sealed to the wall.
The manufacturer of the pier wrap also makes a patented wall liner that attaches to and seals the wall in one simple step. It reduces installation time by several hours. Like the pier wrap, it is available from the manufacturer.
Save Money By Using Crawl Space DIY Kits
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.
