"Great job, fair estimate. Workers were very professional. Did a great job protecting the flooring, and workmanship was fantastic. Had extra blown in insulation added to my attic. Work included repairing/replacing any missing attic insulation baffles and pest exclusion as necessary."

"This company is fantastic! 1. Out of the 5 companies I was considering for insulation replacement (yes 5), their quote was the only one that was itemized and understandable. You knew each task you were paying for as well as what the workers were promising to deliver, which is extremely important when dealing with contractors. I found this out having met with 20+ over the last month. 2. They had the most reasonable price, and Rory in particular worked to volunteer his expertise on what our situation needed/did not need with an honesty that is hard to come by because it did not come off as self-serving or trying to take advantage of our lack of expertise. 3. They were reliable, on time, and very communicative every step of the way. They touched base frequently about our complicated situation, they were available for price discussions, and they were direct in communicating arrival and finishing times. I was extremely impressed. 4. The individuals at this company went above and beyond the call of duty. Rory was a pleasure to deal with; he reminds me of the neighbor you want to have because he has great advice, good contacts if you need work outside his company, and reasonable suggestions for what you can do to fix things, and to boot he was extremely available. He even answered our many calls with random questions off-work hours AND he volunteered to come out himself again outside of work hours just to help figure out the steps to fixing our problem. Debbie was affable and an organized presence on the phone. The other staff we worked with- Santiago, Rafael, Luis, and Felix- were all extremely courteous and hardworking during the projects. 5. They worked to coordinate with other contractors without me having to micromanage anyone. I had a roofing company, arborist/tree service, and vent cleaners on site. They were able to navigate their own working space and work in tandem on the roof with the roofers to replace the insulation on the cathedral portion of the house when the underdeck was ripped off, as well as add baffles appropriately. 6. They brainstormed to fix problems we were having at extremely reasonable prices. Example: The attic portion of my home was missing half the ceiling (had to be removed because of extensive mold damage) and they helped me place drywall so we could replace the insulation on the timeline we initially agreed to. It saved my husband and me a lot of money and heartache. What more could you want from a company? The biggest impression I walked away with is that this company actually cares about your situation. My husband and I were purchasing a new home in need of a lot of repairs. We have a toddler and I am third-trimester pregnant. With the move, the unpleasant relationship we had with the previous owners of our home, the strain on our finances, and the overwhelming stress of finding new problems everywhere we looked, I can only say I am extremely grateful we went with Madrona Home Services. Thank you!"

"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"

"Lake Atitlan Insulation did an excellent job in my attic. They removed the old insulation, installed a solar attic vent, replaced the bathroom vent duct, and added new blown-in fiberglass insulation. They also installed radiant barrier on all the attic roof rafters. The work was completed professionally and thoroughly. I highly recommend them."

"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."

"I’m very satisfied with the insulation work performed under my house. My home is now toasty warm on my feet. Phillip and his worker showed up on time, went about their work and cleaned up the mess created in the process. I am greatful that I found such a competent company."

"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"
