Our crawl space had a musty smell for as long as we've owned the house. The team removed the mold that was there and encapsulated the whole space, and they were careful to work around our radon vent pipe the whole time.

Local knowledge
Crawl Space Encapsulation for Glendale Heights, IL homes
Crawl Space Encapsulation in Glendale Heights tends to start the same way mold does across DuPage County: plumbing leaks and poor ventilation that let damp air linger and mold spread. When that moisture sits for even a day or two, mold takes hold, and that is when homeowners from Glen Ellyn, Bloomingdale, Carol Stream and the rest of Glendale Heights call us.
We handle crawl space encapsulation for Glendale Heights the right way. We find and fix the moisture source first, because mold always returns if the water problem is left behind, then we contain the area and remove the mold safely.
Our team is based in Winfield, about 10 minutes from our Winfield base, so we can usually reach a Glendale Heights home the same day. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.

Good to know
Crawl Space Encapsulation in Glendale Heights, IL: common questions
Do you remove existing mold before encapsulating?
Yes, encapsulating over active mold growth doesn't solve the problem. We remove and treat existing mold first, then install the vapor barrier.
How long does crawl space encapsulation take?
It depends on the size of the crawl space and how much remediation is needed first, but most projects are completed within a few days.
Is my crawl space a good candidate for encapsulation?
Dirt crawl spaces with recurring moisture, musty odors, or visible mold on framing are typically good candidates. We can assess yours during an inspection.
Do I need to leave my Glendale Heights home during the work?
Usually no. We seal the work area under negative air, so most of the Glendale Heights home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Will encapsulation affect my radon mitigation system?
No, we coordinate the vapor barrier installation carefully around existing radon vent piping so the system continues working as intended.
Does encapsulation stop mold from coming back?
It significantly reduces the ground moisture that feeds mold growth, which is the main reason crawl spaces develop recurring problems.
How do you keep the mold from coming back after crawl space encapsulation?
We fix the moisture source first, not just the mold, then dry the structure and recheck it. That is what keeps mold from returning to a Glendale Heights home.
Do you serve Glendale Heights?
Yes. We cover all of Glendale Heights, including Glen Ellyn, Bloomingdale, Carol Stream, and the rest of the Glendale Heights area. We are based in Winfield, about 10 minutes from our Winfield base, and answer our own phone around the clock.
