The PNW moisture story

Rain and ground moisture make vented crawl spaces damp. Damp leads to mold, wood rot, and rodents — which destroy insulation and air quality. The fix is to control moisture and insulate.

Floor-joist vs. wall insulation

We insulate between floor joists for warmer floors, or insulate the crawl space walls as part of a sealed, encapsulated system. We’ll recommend the right approach for your home.

Encapsulation & vapor barrier

Encapsulation adds a heavy vapor barrier across the ground and up the walls, sealing out moisture. Paired with closed-cell foam, it transforms a damp crawl space.

Removal of damaged material

We remove pest- or water-damaged insulation, sanitize, and re-insulate. Energy Trust floor-insulation incentives may apply (example: around $0.30/sq ft for some floor projects; amounts vary). Check rebates →

Crawl Space Insulation — FAQs

Should I insulate the floor or the walls?

It depends on moisture and ductwork. We assess your crawl space and recommend floor-joist insulation or full wall encapsulation.

Will encapsulation stop the musty smell?

Sealing out ground moisture usually resolves musty odors and discourages mold and rodents.

Do you handle rodent cleanup?

Yes — see removal & replacement for contaminated insulation.
