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.

We had mold after a slow leak under the sink. They inspected it, explained the plan, and left the space dry and clean.
Honest company. They told us the mold patch was small enough to clean ourselves and even explained how.

Local knowledge
Crawl Space Encapsulation for Somerville, MA homes
Crawl Space Encapsulation in Somerville tends to start the same way mold does across Middlesex 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 Winter Hill, East Somerville, Cambridge and the rest of Somerville call us.
We handle crawl space encapsulation for Somerville 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 35 minutes from our Boxford base, so we can usually reach a Somerville 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 Somerville, 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.
Is the crawl space encapsulation you do in Somerville to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across Middlesex County.
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 Somerville home.
Do you serve Somerville?
Yes. We cover all of Somerville, including Winter Hill, East Somerville, Cambridge, and the rest of the Somerville area. We are based in Boxford, about 35 minutes from our Boxford base, and answer our own phone around the clock.
