Cleaner, drier crawl spaces in Issaquah
Tucked between Cougar, Squak and Tiger mountains, Issaquah gets more rain than Seattle, and hillside homes often deal with runoff. 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 Issaquah, including the Issaquah Highlands, Olde Town, Squak Mountain and Talus: debris and rodent waste removal, sanitizing, vapor barriers, drainage and new under-floor insulation.

“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…”
“Ahmad and his crew did a great job to complete the work. They were very efficient. They removed old insulation, sanitized and put new insulation in the attic and cleaned out the crawl space. Also mended some torn nets. It was also easy to get an estimation and schedule the work.”
