Cleaner, drier crawl spaces in Seattle
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. High humidity and musty odors don't stay below the floor: some contractors estimate that up to 40% of the air on the first floor comes up from the crawl space.
Attic Crew cleans and protects crawl spaces throughout Seattle, including Ballard, Queen Anne, Capitol Hill and Wallingford: debris and rodent waste removal, sanitizing, vapor barriers, drainage and new under-floor insulation.
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.

“We needed some rodent proofing and all of the insulation in our raised house replaced. I was able to get them out for an estimate within days and schedule the work within a couple of weeks. The work was done in about 7 hours and looks fantastic. Everybody was very friendly and professional.”
“Joey and his crew arrived on time. They were very professional and considerate to our needs. We needed our old insulation swapped out and have our attic and crawl space rodent proofed. They did an amazing job at doing so. He was considerate enough to take pictures of all work completed and presented me everything.”
“After 19 years, my crawl space was a disgusting mess due to being inhabited by rodents. Jay came to my home to make an inspection and recommendations. He showed me photos of the problem and explained exactly what was needed to be done. Two weeks later as planned, Wais came out with the crew right on time. When the job was completed, I was again shown with photos exactly what was done and was beyond satisfied with…”

A heavy plastic sheet laid over the soil, and often up the walls and around piers, that keeps ground moisture out of the crawl space. In our wet climate it's one of the most effective ways to reduce humidity and musty odors.
