According to the EPA, the air in your home can be two to five times more polluted than the air outside! The build-up of vapors from everyday household products such as aerosols, pesticides, and cleaning solvents leave behind contaminants that affect indoor air quality. Tightly built and energy efficient homes lack proper ventilation, plus excess moisture in the air created by everything from doing laundry to the weather outside can cause mold and mildew inside.

Ventilation and dehumidification in your basement or crawl space gets rid of the excess moisture and humidity that causes mold, dampness, musty odors – as well as chemical contaminants and allergens. The result is a fresher, cleaner, and healthier living environment.

For the crawl space, our Concrete for Crawlspaces will minimize moisture, dampness, and odor associated with mold and mildew, and helps improve the air quality of your whole home from the bottom up.

We had had our basement flood twice in a couple of years. Perma Dry found a poorly sealed crack in a foundation wall and repaired it beautifully. Even with huge rainstorms, we haven't had a drop of water. Highly recommended. Macall Gordon

We've had several very wet storm seasons since the installation three years ago, and the basement has remained bone dry, even while water covers large parts of our yard. We've doubled the usable space in our house. Scott Jarol

These folks were EXCELLENT. I mean "first class". Perma Dry delivered on their promises. I've had perfect and wonderful dryness. Nope, they didn't pay me to write this. I'm just a genuinely satisfied customer. John Austin
