Get matched with top insulation pros in Seattle, WA

"I had them come out to do a blower test to see where the leaks were for my house. They came out same week. The test was very cool. I got to feel where all the leaks were coming from in my house and see where we were missing insulation. I'd recommend having them come out and do this before having anyone do insulation. I plan on having them come out and fix my leaks"

"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 (Jo Estrada) had insulation installers come to our century old house to remove old attic insulation, do a bit of mold remediation, insulate the bathroom fan exhaust, cover the two previously open gable spaces at either end of our roof, then blow in new cellulose insulation. All this took a day, and all was cleaned up like nothing happened. Polite, efficient, professional, and the price was competitive."

"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."

"We had Lake Atitlan Insulation remove our old insulation and replace it with R-38. I enjoyed working with Nanni from the initial meeting to the final step of installing the insulation. Very knowledgeable lady and truly exceptional customer service. A highly recommended insulation contractor."

"We literally been roasted in our house especially on the second floor with that late heatwave going on . Eric from Insulation Pro took care of our attic. Full insulation replacement. Some mold problems and vents to reconnect . I was skeptic I even tested with the thermostat furnace but it literally did the job. Couldn't be happier."

"Fantastic. Of all the home improvement companies who have worked on many different jobs at this house in six years, Madrona takes the cake for providing the best quality work and amazing customer service. Madrona was the only company who gave us a thorough plan to not only put insulation in the attic but also to improve ventilation and ensure all roof penetrations were properly sealed. They added 1300 ft of R-44 blown fiberglass insulation over existing rock wool insulation that was fine but inadequate, to bring it to R-49. They fashioned a new wood access panel to the attic with a huge covered batt of fiberglass insulation fastened on the upper side and it feels like opening a secure air lock on the rare occasions where we've looked up into the attic. After they sealed all air penetrations in the attic they were very happy to show us what they did before adding the insulation. They installed insulation shield around the chimney, six roof jacks for proper venting, and vented kitchen and bath fans to dampered roof jacks, insulated with R-11 fiberglass batts. Four years later, the attic looks fantastic - there is no sign of any moisture and the blown in insulation looks as fluffy and lofty as when it was newly installed. I mistakenly thought one of the bath vents had been filled with insulation foam, causing the fan to not work very well, and Madrona sent someone out the next day even though the job was completed four years ago. Curt investigated and then politely and patiently explained that the side vent had been replaced with a better roof vent. And indeed, the fan was blowing air through the roof vent they installed and it is the old fan that is the problem, not Madrona's work. It would be wonderful if all companies stood behind their work this way."

"Great customer service! I am very pleased with the way they were so attentive and Iâ m happy the insulation inspection passed without any issues. Highly recommended."

"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 👍👍👍👍👍"

"We had a wonderful attic insulation experience with Madrona Home Services! They had the best pricing, including the Puget Sound Energy discount and they managed all the paperwork. We were able to schedule two weeks after the quote, and their team worked fast and efficiently on installation day. They removed old saw dust insulation and laid down batting, as well as going above and beyond by creating an 8x8 storage platform. Our house feels noticably cozier with consistent temperatures. 10/10"
