What We Do

What Our Crawl Space Encapsulation Service Actually Covers

Every Kent, WA Crawl Space Encapsulation job starts with an inspection, not a generic package — here's what that typically includes.

Crawl Space

Standing Water Extraction

Extraction equipment includes submersible pumps sized for tight crawl space access points.

Crawl Space

12–20 Mil Vapor Barrier Liner

Liner thickness is selected based on foot traffic and how the space will be used going forward, not a flat default.

Crawl Space

Foundation Vent Sealing

Sealed vents are paired with mechanical dehumidification so the space doesn't just trap humidity instead of venting it.

Crawl Space

Dedicated Sump Discharge

We route discharge lines well away from the foundation so pumped water doesn't just cycle back in.

Crawl Space

Insulation & Duct Sealing

Exposed ductwork inside an unencapsulated crawl space collects condensation, which we address by insulating and sealing ducts while the space is open.

FAQ

Frequently Asked Questions About Crawl Space Encapsulation

What's the difference between a vapor barrier and full encapsulation?

We can scope either option depending on your budget and how severe the existing moisture problem is.

How thick should my crawl space liner be?

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.

Do I need to seal my foundation vents?

Some jurisdictions have code requirements around vent sealing, which we'll flag during the inspection if relevant.

Will encapsulation fix a musty smell in my house?

Often yes, if the crawl space is the source — sealing and dehumidifying typically resolves musty odors within a few days of installation.

Can you encapsulate a crawl space with standing water?

Yes — we extract existing water first, then proceed with liner and vent sealing once the space is dry enough to work safely.

How long does crawl space encapsulation take?

Most residential jobs finish in one to two days depending on square footage and how much prep work is needed.
