Heavy-gauge vapor barriers, sealed foundation vents, and a dedicated sump discharge line so your Somerville, NJ crawl space stops feeding moisture into the floor joists above it.
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.
Every crew member is trained specifically on liner installation, seam sealing, and vent encapsulation, not general basement work.
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.
We scope every Crawl Space Encapsulation job in person before quoting it, since two properties with the same symptom rarely need the same fix.
Before any liner goes down, we pump out existing standing water and remove debris left behind by prior drainage failures.
Liner thickness is selected based on foot traffic and how the space will be used going forward, not a flat default.
Open foundation vents pull in humid outside air, which is often the real driver of Somerville, NJ 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.
We take humidity and moisture readings to establish a baseline before recommending a system.
We explain trade-offs between liner thickness options so you can choose what fits your budget and goals.
Most residential encapsulations finish in one to two days depending on square footage and access.
"Found out our old vapor barrier had huge gaps at every seam. They redid it properly and sealed the vents too."
— Somerville 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."
— Somerville Customer
"They caught duct condensation we didn't even know was happening down there. Sealed everything up during the same visit."
— Somerville Homeowner
"Humidity reading before was over 80%. After encapsulation it's holding steady in the 50s."
— Somerville Customer
We can scope either option depending on your budget and how severe the existing moisture problem is.
We'll recommend a thickness based on how the space is actually used, not just a default.
In most Somerville, NJ climates, yes — open vents pull in humid air that undoes a lot of the benefit of the liner alone.
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.
Spaces with extensive prior water damage or debris may take longer — we'll give you a realistic estimate up front.
