Sealing Concrete Block Walls

If your crawl space has block walls, special care will need to be taken when sealing the space. The block will need to be sealed completely, but visibility is needed to allow for termite inspection.

Our clear WallCap System is the ideal solution! It will seal the top of the wall, but its clear design will help keep you protected from unwanted pests.

Sealing Your Crawl Space

Encapsulating your crawl space with a durable liner, vent covers, and an airtight door is one of the most cost-effective ways you can upgrade your home's energy efficiency, while also avoiding expensive repairs later on.

Installing a crawl space vapor barrier keeps cold winter air out of your crawl space -- and away from your furnace, air ducts, water heater, and pipes.

Keeping hot, humid summer air out of your crawl space will prevent condensation from forming on all surfaces in your crawl space as it cools.

The bottom line? Your crawl space is protected from cold winter air and the moisture and humidity that would lead to rotting wood, ruined fiberglass, and an unhealthy home environment.

Keep Pests Out Of Your Crawl Space

If your crawl space is moist, dark, and filled with rotting wood, it's prime real estate for termites, carpenter ants, beetles, and other wood-destroying insects. They love that stuff!

It's also a great winter home for rodents, snakes, and other small animals. They will happily live, breed, and die inside your crawl space.
