"Zero complaints. I have worked with Insulation Northwest twice now and have been very satisfied both times. The sales agent worked with me to find the best and most cost-effective solution, the customer service team is responsive, and the installers were professional, curtious, and pleasant. I recommend Insulation Northwest for all your insulation needs!"
"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 did a great job. Sprayed insulation in our walls and rolled insulation in the attic space. They were fast and professional, skilled and easy to communicate with. Would recommend them 100%"
"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."
"I hired insulation pro inc to replace my old insulation in crawl space

"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."
"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"
"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 👍👍👍👍👍"
"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."
In Kirkland, check for less than 12 inches of attic insulation, visible gaps, or damp insulation material. Watch for uneven room temperatures, condensation on windows, or icicles forming on gutters. If an energy audit reveals heat loss or your HVAC runs constantly, it’s time to schedule insulation service—ideally before fall to prepare for the region’s wet, cold season.

In Kirkland, unexpected costs during insulation service often arise from the need for air sealing, vapor barriers, or moisture control upgrades. Discovering mold, pest infestations, or outdated wiring can also add to project scope. Homes built before the 1980s may require asbestos testing.
