Why mold is a problem in Seattle homes

Seattle gets measurable rain on roughly 150 days a year, and the damp season runs from October well into spring, which keeps attics, basements and crawl spaces humid for months. Building materials that stay wet for more than 48 hours are all mold needs, and it often starts where you can't see it: attic sheathing, crawl spaces and behind walls.

Our mold remediation team works throughout Seattle, including Ballard, Queen Anne, Capitol Hill and Wallingford. We handle testing, containment, removal and repair, and fix the leak, ventilation problem or crawl space moisture behind it.

Local know-how

What we see in Seattle homes

  • The houses

    Seattle has some of the region's oldest housing: early-1900s Craftsman bungalows and foursquares in neighborhoods like Ballard, Wallingford and Capitol Hill, and post-war ramblers further north and south.

  • The wildlife

    Seattle's mix of older homes, dense neighborhoods and wooded greenbelts gives Norway rats and roof rats plenty of food and cover.

  • Under the floor

    Seattle's older homes often have shallow, dirt-floored crawl spaces or partial basements, many still with whatever plastic sheeting went down when the house was built, if any.

Rated 4.9 on Google, with 5-star reviews on Yelp, so you can breathe easy knowing you're in good hands.

★★★★★
“I had a fantastic experience working with the Attic Crew. The fact that they are a one stop shop for clean up, rodent control and insulation made everything so simple and seamless. Their bid was competitive and their quality is excellent. This is definitely the company you want to work with.”
Matt W.Google review
★★★★★
“The Attic Crew delivered just what they said they'd deliver. The attic was sealed off to protect against rodents, vapor barrier was installed in the crawl space, the crew arrived on time and finished by the end of the day and the price came in as promised. It does not get any better than this.”
Shiloh J.Google review
★★★★★
“We moved into a new home that had rodents in the attics. Attic Crew was respectful, polite, and well-priced. Zabi was the Project Manager for our project and he takes such great joy in his work. He spent hours making sure all entry points were sealed and provided before and after photos. He used top tier insulation and cleaned our attic spaces to perfection.”
