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.
No more allergy symptoms since they cleaned the mold from our HVAC and bedroom walls.

Local knowledge
Crawl Space Encapsulation for Florissant, MO homes
Crawl Space Encapsulation in Florissant tends to start the same way mold does across Saint Louis 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 Calverton Park, Berkeley, Hazelwood and the rest of Florissant call us.
We handle crawl space encapsulation for Florissant 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 Valley Park, about 30 minutes from our Valley Park base, so we can usually reach a Florissant home the same day. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.
Florissant specifics
What Crawl Space Encapsulation in Florissant really involves
What sets Crawl Space Encapsulation apart is where it hides: the crawl space floor and walls, exactly where homeowners rarely look. Older and newer homes alike need Crawl Space Encapsulation, from the newer builds near Ferguson to the oldest ones in town. Around here, crawl space encapsulation tends to settle into the crawl space floor and walls before anyone in the house notices it. When people here search for Crawl Space Encapsulation, the growth they can see is usually the last symptom, not the cause.
Our crew has done Crawl Space Encapsulation across Saint Louis County enough to know how plumbing leaks and poor ventilation moves through these homes. Crawl Space Encapsulation is one of the more common calls we get from homeowners around Florissant. Most Crawl Space Encapsulation jobs in the area trace back to crawl spaces and sump pumps around Florissant, a pattern we see week after week. For a home in this area, crawl space encapsulation starts with finding the moisture, because the water is what feeds the mold.
A Crawl Space Encapsulation visit tends to run like this:
- Stop the water source so the problem does not come back
- Remove moldy material to the IICRC S520 standard
- Inspect the affected area and find the moisture feeding the mold
- Recheck the space and document the work for your records
- Dry the structure with commercial equipment until readings normalize

Good to know
Crawl Space Encapsulation in Florissant, MO: 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 Florissant 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.
How soon can you start crawl space encapsulation in Florissant?
We answer our line 24/7 and can usually reach a Florissant home the same day you call, sooner for an active leak.
Do you serve Florissant?
Yes. We cover all of Florissant, including Calverton Park, Berkeley, Hazelwood, and the rest of the Florissant area. We are based in Valley Park, about 30 minutes from our Valley Park base, and answer our own phone around the clock.
