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.

Rated 5 by Syosset-area neighbors
Same-day response when our basement flooded. They dried it out and removed the damaged drywall before mold could spread.
The mold cleanup itself was great. The only hiccup was a reschedule due to weather.

Good to know
Crawl Space Encapsulation in Syosset, NY: 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.
Will my insurance cover crawl space encapsulation in Syosset?
It depends on the cause. When the mold follows a sudden, covered event, there is often coverage. We bill your carrier directly and document the loss so your Syosset claim moves.
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 Syosset?
We answer our line 24/7 and can usually reach a Syosset home the same day you call, sooner for an active leak.
Do you serve Syosset?
Yes. We cover all of Syosset, including East Norwich, Muttontown, Laurel Hollow, and the rest of the Syosset area. We are based in Oyster Bay, about 5 minutes from our Oyster Bay base, and answer our own phone around the clock.
