"Insulation NW was amazing, they came out to give an estimate quickly, had the most reasonable rate of all the bids I saw and were able to schedule me that same week! And the actual insulation process was very speedy. Would recommend working with them!"

"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."

"Friendly service. Was on time and blew insulation in attic over garage. Perfect transaction!"

"The entire process from estimating (Kenny) to project management (Walter) to team members (four), was efficient, respectful of our property and extremely communicative. The team went multiple extra steps to make sure our crawl space free of entry points for critters while installing all new insulation"

"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."

"JTS did an insulation job at nearly half the price. While others made up reasons to charge me more money JTS did an honest assessment and did a fantastic job. His work although I'm no expert looks fantastic and marketably better than what my crawlspace looked prior to him. I am very pleased and would hire him again if such a need occurred. Thanks again!"

"OK, letâ s get this out-of-the-way. The job was a daunting one which was completed to perfection. His work is clean and thorough. But letâ s talk about Arlin. Heâ s kind of dry, with a no problem, can-do attitude. I was kind of worried if he knew what he was getting into because the job was quite challenging (huge expanse at 25 feet in the air, insulating around 40â exposed glulams). No worries - this is an impressive young man. His work is excellent. Highly recommend."

"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 👍👍👍👍👍"
