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.

Same-day response when our basement flooded. They dried it out and removed the damaged drywall before mold could spread.
The inspector used a moisture meter and thermal camera to find hidden mold. Impressive and worth every dollar.

Local knowledge
Crawl Space Encapsulation for Marlborough, MA homes
Crawl Space Encapsulation in Marlborough tends to start the same way mold does across Middlesex 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 Southborough, Hudson, Northborough and the rest of Marlborough call us.
We handle crawl space encapsulation for Marlborough 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 Maynard, about 15 minutes from our Maynard base, so we can usually reach a Marlborough home the same day. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.

If you have noticed a musty smell or a spreading stain in your home, crawl space encapsulation is worth a call before the damp reaches the framing. Crawl Space Encapsulation is one of the more common calls we get from homeowners around Marlborough. A Marlborough home that needs Crawl Space Encapsulation almost always has a moisture story behind it, and it usually starts with air conditioning condensation feeding mold on cool basement and closet walls.

- Recheck the space and document the work for your records

Good to know
Crawl Space Encapsulation in Marlborough, 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 Marlborough home during the work?
Usually no. We seal the work area under negative air, so most of the Marlborough 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.
Is the crawl space encapsulation you do in Marlborough 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.
Do you serve Marlborough?
Yes. We cover all of Marlborough, including Southborough, Hudson, Northborough, and the rest of the Marlborough area. We are based in Maynard, about 15 minutes from our Maynard base, and answer our own phone around the clock.
