What is Crawl Space Encapsulation?

Most people don’t think about their crawl space until it starts causing problems. Damp air, musty smells, mold, and pests often start down below without much warning. With encapsulation, you seal the space to help stop those issues from spreading into your home.

This isn’t just about covering dirt floors. We install heavy-duty vapor barriers and seal up vents and entry points. The goal is simple: keep the outside out and help your home breathe easier.

Keep Pests and Moisture Out

Rodents, insects, and mold love a damp, dark crawl space.


By sealing gaps and laying down a proper moisture barrier, we make it a lot less welcoming.
