We start by pumping out any standing water, then move straight into liner installation and humidity control.
A rushed encapsulation job with unsealed seams or unwrapped piers looks fine on day one and fails within a season. We treat seam sealing and pier wrapping as core parts of the install, not optional add-ons that get skipped to save time.
We follow manufacturer specs on liner overlap and seam tape so the barrier actually holds up over time.
Our technicians carry encapsulation materials on the truck for most standard-size crawl spaces, cutting down on return visits.
Pricing is based on your crawl space's actual square footage and condition, quoted in writing before liner installation begins.
We measure relative humidity before and after installation to confirm the space is actually staying below the threshold where mold and wood rot take hold.
Every Old Westbury, NY Crawl Space Encapsulation job starts with an inspection, not a generic package — here's what that typically includes.
Before any liner goes down, we pump out existing standing water and remove debris left behind by prior drainage failures.
We install heavy-duty liner rated for crawl space conditions, sealed at every seam and pier to stop ground moisture from reaching the floor joists.
Sealed vents are paired with mechanical dehumidification so the space doesn't just trap humidity instead of venting it.
We route discharge lines well away from the foundation so pumped water doesn't just cycle back in.
Exposed ductwork inside an unencapsulated crawl space collects condensation, which we address by insulating and sealing ducts while the space is open.
We ask about standing water, musty odor, and vent condition to gauge scope before scheduling the inspection.
We take humidity and moisture readings to establish a baseline before recommending a system.
You'll see square footage, liner grade, vent sealing, and dehumidifier specs broken out in the written estimate.
We re-test humidity after installation to confirm the space is holding at a healthy level before we consider the job done.
"Our crawl space had standing water and a mold smell we couldn't get rid of no matter what we tried. Full encapsulation with a dehumidifier fixed it in one visit."
— Old Westbury Homeowner
"Sump discharge from the old system was dumping water right back next to the foundation. They rerouted it and the crawl space finally dried out."
— Old Westbury Customer
"Access to our crawl space is tight and awkward, but the crew didn't seem bothered by it at all."
— Old Westbury Homeowner
"Musty smell in our upstairs hallway is completely gone now that the crawl space is sealed."
— Old Westbury Customer
We can scope either option depending on your budget and how severe the existing moisture problem is.
Most residential spaces do well with a 12-15 mil liner; spaces used for storage or with foot traffic often need 20 mil for durability.
Some jurisdictions have code requirements around vent sealing, which we'll flag during the inspection if relevant.
Often yes, if the crawl space is the source — sealing and dehumidifying typically resolves musty odors within a few days of installation.
Standing water doesn't disqualify a space from encapsulation; it's just the first step in the process.
Most residential jobs finish in one to two days depending on square footage and how much prep work is needed.
