Why even install drywall when the spray foam looks this good? 😉

We spayed the basement with 2” closed cell spray foam on the foundation walls to seal it up. Closed cell provides a high-density, waterproof barrier that stops air leaks, blocks moisture, and delivers superior thermal performance in a compact space.

No Rats Allowed.

Spray foam sealed this crawlspace so mice, rats, squirrels and raccoons stay out—not just to keep the house warmer.

The homeowner was having trouble with mice accessing their home through the crawlspace. Although spray foam is generally used for its thermal capabilities, it is very versatile and can be used for many more things besides insulation. Sealing the walls with closed cell can guarantee that no mice enter through this area as it is a very rigid material.
