Crawl Space Insulation

Crawl Space Insulation Services in Greater Richmond, Henrico, Williamsburg, Richmond

Insulation in your crawl space makes the floors above it warmer

Crawl space insulation and air sealing are more important than most homeowners think. Without it, the result is discomfort and energy bills that are higher than they should be. Sound familiar?

The Drying Co./ThermalTec seals and insulates crawl spaces using spray foam or rigid foam insulation, along with a vapor barrier. This proven method can give you greater comfort while lower heating and cooling bills and prevent mold, moisture and pest issues.

    Montpelier, VA - Crawl Space Mold

    Mold needs warm temperatures, high relative humidity and organic material to grow. In our area, crawl spaces create the perfect environment for this. We did a physical wipe down of the joists with an antimicrobial to kill and remove the mold growing on the wood.

    Fiberglass Batts between the joists absorb moisture like a sponge. They hold moisture against the wood joists and fall and sag over time. Their paper backing and the wood floor joists are organic material that often has mold growing on them. We removed the old insulation and installed new, foam board insulation on the crawl space walls.

    Previously, this crawl space had a 6-mil lightweight vapor barrier that was torn and even missing in places. We installed the CleanSpace Encapsulation System. The CleanSpace vapor barrier is a heavy-duty 20-mil liner that is perfect for crawl spaces that have service persons working on equipment, plumbing, or electrical, or for storage. It resists rips and tears, and is fastened to the walls and wrapped around piers sealing the earth off from the home. 

Why fiberglass insulation in the crawl space is bad

A common way to improve comfort and save energy in a home built above a crawl space is to insulate the crawl space with fiberglass batts installed between the joists and vent the crawl space to allow outside air to circulate beneath the home.

The problem is that moisture from your crawl space moves upward into the living area of your home. As this happens, the fiberglass between your floor joists absorbs moisture and becomes soggy and heavy. This will cause the insulation to lose its R-value. Not only that, but the wet fiberglass batts can fall and cause mold growth and rot.

A damp crawl space won’t just cause damage below the home. As much as 40% of the air you breathe in your upstairs living area comes from the basement or crawl space. This means there's a high risk for poor air quality from airborne mold spores. These are serious problems.

How we can insulate and improve your crawl space

If you have cold floors, high heating and cooling bills, or uneven temperatures throughout your home, we have the solutions to help solve your problems.

Insulate crawl space walls and floor

To get the most comfort and energy savings benefits possible, you need insulation that performs well in the damp environment. That's why we insulate crawl space walls and the rim joist with SilverGlo rigid foam insulation and not fiberglass.

Unlike fiberglass insulation, rigid foam won't absorb moisture, lose R-value or encourage mold growth. It also won't compress or fall out of place. SilverGlo also had a radiant barrier, which reflects heat back into your crawl space for ultimate energy savings. Although fiberglass is one of the cheapest insulation materials, having to rip it out and replace it will cost you more in the end. Insulating the crawl space floor is also an option and can help reduce heat loss. We insulate dirt crawl space floors with TerraBlock foam insulation.

Seal the crawl space

Sealed crawl space

Crawl space sealed with the CleanSpace System.

To reduce moisture and relative humidity in the crawl space, we install the CleanSpace liner over the crawl space walls and floors, isolating your home from the earth. The rim joist is sealed with either spray foam insulation or foam boards to keep out unconditioned air and prevent condensation. Any remaining moisture can be removed with a crawl space dehumidifier. When combined with air sealing and dehumidification, the CleanSpace vapor barrier will eliminate mold growth and rot from your crawl space and make the whole house healthier. If you have a wet crawl space, we offer products to solve water leakage and can recommend the right drainage system for your situation.
