If you are like most homeowners, you do not give much thought to your crawl space. In homes without a basement, a crawl space allows easy access to plumbing, heating cooling systems, and electrical wiring.

But this out-of-sight, out-of-mind area can be a haven for high humidity and moisture. Your crawl space can play host to a number of problems that affect the value of your home and your quality of life, from pests, mold, and odor to wood rot and poor air quality.

At TerraFirma, we have encountered every home problem you can imagine, and your crawl space is no exception. Since 2005, our local experts have partnered with homeowners across the Pacific Northwest to deliver peace of mind and protect the investment they have made in their homes.

TerraFirma offers comprehensive encapsulation solutions to keep your crawl space clean, dry, and secure from outside threats. Our unique products and services keep out destructive moisture while greatly improving your indoor air quality. In most homes, TerraFirma can even turn your crawl space into a clean, watertight area suitable for storage.

Fix it with TerraFirma, your partner in bringing your home back to life.
