Better insulation for Seattle homes
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. Insulation settles, gets compressed and is often damaged by rodents or moisture over the years, and heat escapes through the top of the house.
We remove old, compressed or contaminated insulation and install Knauf EcoBatt®, blown-in or spray foam insulation in homes across Seattle, from Ballard, Queen Anne, Capitol Hill and Wallingford. The result is a warmer home through the long heating season, a cooler one during summer heat waves and lower energy bills.

“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.”

“I was super impressed with the team that came a took care of what appeared to be a nightmare attic. The team lined our floors and walls from the entrance of the house to the attic trap door, removed all the old insulation and debris, then cleaned and sanitized the whole attic, covered any openings to prevent rodents in the future and closed off any ceiling openings with foam around each of our recessed lights.…”

How do I know if my insulation needs replacing?
High energy bills, rooms that are hard to heat, insulation that's thin, compressed or below the top of the joists, and any sign of rodents or moisture in the insulation all point to replacement. We measure what you have during the free inspection.
What insulation do you install?
Knauf EcoBatt® batts made with ECOSE® Technology, blown-in fiberglass and cellulose, and spray foam. We recommend what fits your attic, crawl space, budget and goals.
When is spray foam the right choice?
Spray foam seals air leaks as it insulates, so it works well on attic roof decks, rim joists, crawl space walls and other spots where air sealing matters as much as R-value. For an open attic floor, blown-in insulation is usually the better value. We'll recommend the right material for each area.
