“Erica and her team found the actual source of my basement leak after two other companies gave up. Fixed it in one day and backed it with a lifetime warranty. Couldn't be happier.”

Crawl Space Waterproofing
Permanent crawl space encapsulation with a cement parge coat — built to last decades, not years.
(630) 474-5325What's included
Most contractors line crawl spaces with plastic sheeting that tears, sags, and fails within a few years. We do it right: a troweled cement parge coat over the floor and lower walls. It seals out moisture permanently, won't degrade, and stands up to foot traffic, pests, and time.
- Cement parge coat — not plastic sheeting that tears and fails
- Permanent moisture seal that lasts the life of the home
- Pairs with drainage + sump system for full protection
- Improves indoor air quality & structural longevity
