"The estimator was great, he listened to my concerns and offered options that suited my needs. The workers were respectful and got to work right away. I had insulation installed under my floor in the crawl space, a ground cover installed, ducts sealed, and the garage ducts wrapped. I was very happy with the insulation results, I no longer feel a difference in air temperature between rooms. I was not thrilled with the ground cover nor the garage ducts wrap, these jobs seemed rushed. The ground cover had multiple holes and was not put down with a function or pleasing aesthetic in mind. The garage ducts wrap is definitely helping with the loss of heat, but it looks clumsy with white tape all over the place. Overall I'm satisfied. I just think parts of the job were rushed."

"Insulation Co recently performed a crawlspace cleanout. Jo Estrada performed a bid for my home based upon on-line square footage and floor plans very quickly. His staff of 3 men arrived at about 7:30 AM and completed the crawlspace cleanout in about 7 hours. Several things that I learned during this process my 1998 built home: Had insulation with formaldehyde Had R-19 insulation - New installed insulation was R-30 The old insulation was no longer efficient after 20 years The new (R-30) insulation will be efficient for 30 years Insulation Co also does attic insulation replacement When they completed the crawlspace cleanout, the crawlspace looked better than it did when the home was new."

"We were considering upgrading our insulation but weren't sure if it was worth the investment. After consulting with Lake Atitlan Insulation, they convinced me it was the right choice. The insulation they installed not only made our home more comfortable but has already saved us money on energy costs."

"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 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."

"I requested an inspection of our attic to assess what needed to be done to improve its condition. I thought it may need an upgrade. Other venders earlier had told me that they would recommend new and/or added insulation, air sealing, mold treatment, etc. to the tune of multiple thousands of dollars. Brennen from Attic Doctor was the one who did our inspection. He explained why our attic really did not need much work to make it good. Contrary to others, he said we didn't need to upgrade our insulation, but just rearrange the already-adequate batting to free up the soffit vents and cover gaps, along with doing my own air leaks sealing or hiring a handyman at a much lower cost. He said we had no mold, as was asserted by another vendor. Washington State does not oversee the insulation vendors well so many can throw out their shingle with minimum expertise (effective lobbyists in Olympia?). Brennen has a college degree in construction science and knows his stuff. He was also honest with me"

"I hired Acorn Attics to insulate my house and I couldn’t be more happy with their work. Phil and his crew were on time, friendly and incredibly hard workers. He worked with me on scheduling and made sure to keep our project moving even when we had a setback with another repair. I highly recommend them. They will get the job done. Thank you Acorn Attics and Crawl Spaces!!"
