Heavy-gauge vapor barriers, sealed foundation vents, and a dedicated sump discharge line so your Farnham, NY crawl space stops feeding moisture into the floor joists above it.
Farnham, NY crawl spaces vary a lot in how they were originally built, and a liner that's correct for one home can be undersized for another depending on foot traffic and storage use. We size thickness to how the space is actually used.
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.
A dedicated crawl space dehumidifier is sized to your square footage, not a one-size-fits-all unit.
Every Farnham, NY Crawl Space Encapsulation job starts with an inspection, not a generic package — here's what that typically includes.
Extraction equipment includes submersible pumps sized for tight crawl space access points.
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.
Open foundation vents pull in humid outside air, which is often the real driver of Farnham, NY crawl space condensation — we seal them as part of encapsulation.
We route discharge lines well away from the foundation so pumped water doesn't just cycle back in.
We also check subfloor insulation for water damage and replace anything compromised before closing the liner.
This helps us bring the right liner thickness and dehumidifier size on the first visit.
A technician physically enters the space to check for standing water, existing liner condition, vent count, and duct exposure.
We explain trade-offs between liner thickness options so you can choose what fits your budget and goals.
We re-test humidity after installation to confirm the space is holding at a healthy level before we consider the job done.

A vapor barrier is just the liner on the ground; full encapsulation seals vents, walls, and often adds a dehumidifier for complete moisture control.
We'll recommend a thickness based on how the space is actually used, not just a default.
Some jurisdictions have code requirements around vent sealing, which we'll flag during the inspection if relevant.
If the smell persists after encapsulation, that usually points to a separate moisture source we'd need to investigate.
Yes — we extract existing water first, then proceed with liner and vent sealing once the space is dry enough to work safely.
Most residential jobs finish in one to two days depending on square footage and how much prep work is needed.
