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.

Reviews

Called about a musty smell and they walked me through every step before starting. The area was contained properly and the odor was gone when they finished.
Professional containment, HEPA vacuuming, the whole process was textbook. Worth hiring certified pros.

Local knowledge
Crawl Space Encapsulation for Centreville, IL homes
Crawl Space Encapsulation in Centreville tends to start the same way mold does across Saint Clair County: air conditioning condensation feeding mold on cool basement and closet walls. When that moisture sits for even a day or two, mold takes hold, and that is when homeowners from Alorton, East Saint Louis, Sauget and the rest of Centreville call us.
We handle crawl space encapsulation for Centreville 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 Columbia, about 20 minutes from our Columbia base, so we can usually reach a Centreville home the same day. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.

Crawl Space Encapsulation is one of the more common calls we get from homeowners around Centreville. For a home in this area, crawl space encapsulation starts with finding the moisture, because the water is what feeds the mold.

By the time a family calls us for Crawl Space Encapsulation, they have usually already seen a musty smell or a spreading stain.

Good to know
Crawl Space Encapsulation in Centreville, 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.
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 Centreville home.
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.
Is the crawl space encapsulation you do in Centreville to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across Saint Clair County.
Do you serve Centreville?
Yes. We cover all of Centreville, including Alorton, East Saint Louis, Sauget, and the rest of the Centreville area. We are based in Columbia, about 20 minutes from our Columbia base, and answer our own phone around the clock.
