Get matched with top spray foam insulation pros in Seattle, WA

"They did a great job on our drill-n-fill project. Will use them again once our home improvement fund can handle the hit for spray foam in the garage."

"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."

"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."

"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 👍👍👍👍👍"

"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."

"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."

"Wry communicative and friendly! They did great work on the insulation that was needed under our home."

"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."

"They were all very courageous Card, did a great job and very clean."

"Incredible experience. Would definitely recommend to anyone looking for insulation work, especially in an older home."
