Get matched with top insulation pros in Vashon, WA

"Insulation Northwest did a fantastic job insulating my 1944 house recently, with Drill & Fill in ground-floor walls never before insulated, plus a complete insulation of the second floor attics and interior walls. They were super-careful cutting and drilling my old cedar shakes, replacing them perfectly and caulking them afterwards. They worked around plants without damaging a thing while doing the walls outside. I have old lath and plaster walls but blowing in the fill left not even a hairline crack or any trace on the inside. Much appreciated! They spent two long days at my house and they were clean, friendly, professional, and helpful . This is my second time hiring Insulation Northwest and I give them my highest recommendation."

"PNW Insulation completed many insulation tasks on a house for me including wall insulation, crawl space and attic. They were very accommodating with scheduling the work at various times as each area was ready. I highly recommend them."

"Lake Atitlan Insulation did an excellent job in my attic. They removed the old insulation, installed a solar attic vent, replaced the bathroom vent duct, and added new blown-in fiberglass insulation. They also installed radiant barrier on all the attic roof rafters. The work was completed professionally and thoroughly. I highly recommend them."

"I hired insulation pro inc to replace my old insulation in crawl space Eric came and give me a reasonable price And they over delivered. Highly recommend them"

"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!"

"We contacted them to do blow-in and crawl space insulation, but they were very thoughtful and thorough in looking at all the factors with our house and recommending against blowing in the walls and ceilings. In the end we only did the crawl space. I was impressed with their honesty and high ethical standards. They could have easily taken our money and blown in the walls and ceilings, but they seem to truly care about getting good results and giving customers top value. The work they did on the crawl space was excellent. It feels strange to call insulating a crawl space beautiful, but they truly did a beautiful job and we are thrilled to have cold air no longer seeping into our house from below."

"Unbelievable company such great work. John is one of the best business man I have ever dealt with he deserves 20 stars. And his crew does to if you ever need insulation go here. No place else. Best in the state 👍👍👍👍👍"

"Sprayed insulation on roof and installed fiberglass insulation + rockwool in walls, and sealed penetrations. Very clean install and left the site tidy, and reasonable pricing. Would easily recommend."

"The job was done timely. They went out of their way to make sure everything from replacing the insulation to a thorough rat abatement was done right and explained everything to me. They even installed some bird spikes for me."

"I’m very satisfied with the insulation work performed under my house. My home is now toasty warm on my feet. Phillip and his worker showed up on time, went about their work and cleaned up the mess created in the process. I am greatful that I found such a competent company."
