"Insulation NW did an excellent job of removing old inadequate insulation from an attic and crawlspace and replacing it with new insulation and wrapping the ductwork. They had two crews, one for the attic and one for the crawlspace, working for many hours to complete the job. A vapor barrier was also installed in the crawlspace. We paid a very reasonable price after the large PSE Rebate was applied."

"Insulation Co., LLC did an excellent job in cleaning and repairing our crawlspace. All old, torn and worn-out insulation was replaced, holes and gaps were sealed, and a new vapor barrier was installed. The repaired crawlspace looked like new."

"The lake atitlan, insulation team just finished replacing our old blown in insulation in our attics with white R-38 rolled batt insulation. Overall, we were very happy with their work and attention to detail. Everything was spotless when they left. They were also a few thousand dollars less expensive than a bid we got from a larger local chain. The old insulation was blocking the soffit vents (under the gutters) allowing moisture and black mold to develop on the underside of the roof sheeting. First, they built a plastic tunnel from the front door up to the upper attic access door in the top of a closet near the bedrooms. This prevented any debris from the job filtering into the house as well as protecting the carpet. Next, they removed all the old insulation with the assistance of a giant vacuum. The black mold on the underside of our roof sheeting was treated and the new insulation installed. It now looks like a field of freshly fallen snow up there and no blocked vents."

"It went very well from the estimate process. Rory took the time to explain the process. As I had questions, he took the time to talk to me and explain in detail. Deb coordinated the scheduling extremely well. Among the estimates I got they were the most reasonably priced. I started out only doing the attic. They did such a good job, I decided to go ahead and have the crawlspace insulated as well by Madrona Insulation. BTW, shout out to a terrific installation crew!"

"Erick with AG construction came to my rental a week ago. He had the proper equipment to crawl under the house and determine what I needed to fix broken heat pipe, replace vapor barrier and replace insulation from a plumbing leak. I also had signs of rodents. He gave me a bid that was reasonable and was able to have his team on the job within a week. I stopped by as the work was being done and saw old insulation in bags headed for the dump. The area was left clean and his photos of the job look great. This is a very professional company and I would use them again for any crawl space work. "

"Acorns Attic was hired for a rodent removal job and I had some insulation replaced since it was dirtied with rodent droppings. Phil and team did a great job. They took plenty of pictures of before and after. I haven’t had rodents since they patched up the openings and the insulation looks great!"
