"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."

"ATI did an amazing job insulating my home. Their team was professional, efficient, and used top-quality materials. I noticed immediate improvements in comfort and energy savings. Highly recommend them for any insulation needs!"

"Shon is the nicest person. He really knows his product and his installs are perfect every time. He listen to exactly what your needing and followed thorough"

"Daniel was pleasant to talk to on the phone and got my job scheduled almost immediately because I was in a hurry. His workers that did my job showed up on time and were very courteous and clean. They did a fantastic job of vacuuming out all of our rat soiled blown in insulation in the attic. I asked them to make sure and remove all the droppings because I need to go up there and seal. The 1500 sqft job took 2 men about 3.5 hours and they cleaned up after themselves. I would hire them again happily."

"Fast clean very nice job done very impressed"

"Enrique and Alex performed the task. They were punctual, polite and very quiet, which I was very happy with. I expected the hose and insulation to have been noisy. Great job, thanks so much."

"The job went excellent. Shay repaired about 100 lineal feet of fencing that had blown down. He placed new posts in new concrete. Did all new framing and even got me a great deal on the fence boards from a local supplier rather than paying over double at the big box stores. He really cares about doing a great job and is meticulous and makes sure everything is done right instead of trying to rush through it. I woukd absolutely recommend him to anyone looking for work done around their home or property. I'll be hiring him to rebuild my deck this spring as well!"

"They showed up on time. Very professional service. Excellent price for an excellent service. They upgraded the insulation in my crawlspace and attic. Very satisfied with this company."
