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.

Great communication from the first call. They tested the air, handled the removal, and rechecked the space before signing off.
The mold cleanup itself was great. The only hiccup was a reschedule due to weather.

Local knowledge
Crawl Space Encapsulation for Andover, MA homes
Crawl Space Encapsulation in Andover tends to start the same way mold does across Essex County: crawl spaces and sump pumps around Andover that struggle to keep up during wet spells. When that moisture sits for even a day or two, mold takes hold, and that is when homeowners from North Andover, Lawrence, Methuen and the rest of Andover call us.
We handle crawl space encapsulation for Andover 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 Boxford, about 10 minutes from our Boxford base, so we can usually reach a Andover 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 Andover, MA: 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 Andover home during the work?
Usually no. We seal the work area under negative air, so most of the Andover 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 soon can you start crawl space encapsulation in Andover?
We answer our line 24/7 and can usually reach a Andover home the same day you call, sooner for an active leak.
Do you serve Andover?
Yes. We cover all of Andover, including North Andover, Lawrence, Methuen, and the rest of the Andover area. We are based in Boxford, about 10 minutes from our Boxford base, and answer our own phone around the clock.
