Heavy-gauge vapor barriers, sealed foundation vents, and a dedicated sump discharge line so your Westport, WA crawl space stops feeding moisture into the floor joists above it.

Westport, WA 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.
Every crew member is trained specifically on liner installation, seam sealing, and vent encapsulation, not general basement work.
Westport, WA crawl space calls get scheduled fast, especially when there's standing water or an active mold smell involved.
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 Westport, WA 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.
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.
We also check subfloor insulation for water damage and replace anything compromised before closing the liner.

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.
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.

"Found out our old vapor barrier had huge gaps at every seam. They redid it properly and sealed the vents too."
— Westport 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."
— Westport Customer
"Access to our crawl space is tight and awkward, but the crew didn't seem bothered by it at all."
— Westport Homeowner
"Musty smell in our upstairs hallway is completely gone now that the crawl space is sealed."
— Westport 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 Westport, WA 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.
Most residential jobs finish in one to two days depending on square footage and how much prep work is needed.
