Good to know
Crawl Space Encapsulation in West Sayville, 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.
How soon can you start crawl space encapsulation in West Sayville?
We answer our line 24/7 and can usually reach a West Sayville home the same day you call, sooner for an active leak.
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.
Will my insurance cover crawl space encapsulation in West Sayville?
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 West Sayville claim moves.

Yes. We cover all of West Sayville, including Sayville, Bayport, Great River, and the rest of the West Sayville area. We are based in Bohemia, about 5 minutes from our Bohemia base, and answer our own phone around the clock.
