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.

Local knowledge
Crawl Space Encapsulation for Great River, NY homes
Crawl Space Encapsulation in Great River tends to start the same way mold does across Suffolk County: heavy rain and seasonal flooding pushing water toward foundations and crawl spaces. When that moisture sits for even a day or two, mold takes hold, and that is when homeowners from East Islip, North Great River, Islip Terrace and the rest of Great River call us.
We handle crawl space encapsulation for Great River 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 Bohemia, about 5 minutes from our Bohemia base, so we can usually reach a Great River 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 Great River, 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.
Is the crawl space encapsulation you do in Great River to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across Suffolk 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.
Do I need to leave my Great River home during the work?
Usually no. We seal the work area under negative air, so most of the Great River home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Do you serve Great River?
Yes. We cover all of Great River, including East Islip, North Great River, Islip Terrace, and the rest of the Great River area. We are based in Bohemia, about 5 minutes from our Bohemia base, and answer our own phone around the clock.
