Crawl Space Encapsulation Benefits

So why crawl space encapsulation? Recent research has shown over and over that closing and insulating the crawl space while controlling water and humidity may reduce the likelihood of critters, pests, mold, poor air quality and more. That is of course if it is encapsulated properly by crawl space professionals.

Crawl Space Waterproofing

Crawl space waterproofing is the best way to address standing water. Wet crawl spaces develop mold and foundation problems. Getting your crawl space fixed is crucial for a healthy home. Water entering the crawl space can be corrected with our Hybrid Crawl Space Encapsulation System™.

Crawl Space Humidity

Crawl Space Humidity is often overlooked or not properly addressed. Crawl space humidity is the #1 cause of falling crawl space insulation, crawl space mold and many structural problems. Addressing mold and sagging floors without controlling humidity is a mistake and not recommended.

Crawl Space Mold Removal

Why should the chemicals used to remove mold be more harmful than the mold itself? Did you know the State of Tennessee Department of Agriculture requires mold remediation professionals that use EPA registered products to have a pest control license? Ask your contractor what they use.

Crawl Space Insulation

The Harvard School of Public Health says if your home is as little as 5 to 10 years old, you likely have one of the 46 million under-insulated homes in the United States. Crawl space insulation and air sealing is vital to ensure your home is energy efficient and comfortable.

The team was very courteous, professional and did a fantastic job!

Crawl Space Vapor Barrier

Crawl space vapor barriers are required by building code but many crawl spaces don't have vapor barriers or even worse, they have one that smells like cat urine!!! Most crawl space encapsulation companies are installing the wrong type of crawl space vapor barrier plastic.

Crawl Space Dehumidifier

No one wants to install a crawl space dehumidifier but let's face it, it is the most reliable way to make sure crawl space humidity is kept at an acceptable level. Many crawl space companies are telling you to install fans only, which can increase humidity in the crawl space and to problems for your home.

Crawl Space Foundation Repair

Crawl Space foundation repair is very common in wet crawl spaces. Standing water and high humidity can lead to wood rot fungus. Plus, termites enjoy the same environment as mold. Be careful how you address foundation issues. Hiring the wrong crawl space contractor may cost more money later on.

Everyone was wonderful from office to the hard working individuals in the crawl space.
