Constraction reviews in Seattle, Washington

Professionals…all of them. Great communication, on time, efficient…everything you want in a contractor/installers. The took before and after pix.

Insulation Co did a attic clean up/insulation replacement project at my home on Camano Island. Jo was great to work with for the estimate, scheduling and pre and post work follow-up and the crew of three guys who did the work were on-time, professional, fast and very knowledgeable! I was very happy with their work and I'm glad such a great company exists! Definitely recommend them and I might have them redo my crawl space as well!

We had water under the house. Ugh. Jo gave us a fair quote in a timely manner. They finished the job under our crawl space when they promised. The job was neat and clean when completed. Jo sent us rebate forms from the gas company and answered a few questions I had. Would highly recommend Insulation Co

They were fast and efficient. They arrived on time and cleaned up when they were finished. I recommend Insulation Co to anyone who needs their crawl space cleaned out and insulation replaced.

Jo Estrada and his workers at Insulation Co. LLC were great to work with. They removed the old insulation and vapor block in my crawl space and put in new material. Jo was always responsive when I wanted to talk with him and his workers were top-notch. His pricing was fair. I never had the feeling that I was being taken advantage of or treated unfairly. The workers did a thorough job and cleaned up like they'd never been here. I would definitely hire Jo and his colleagues again. Richard in Seattle

Insulation Co did a great job with my attic mold remediation and insulation replacement. The team was professional, on time, and transparent throughout. Pricing was fair, and they explained everything clearly—no pressure or upselling. Highly recommend if you want honest, quality work.

Jo and Insulation Co. were perfect. I chose them based on reviews. They walked me through getting my 1925 vermiculite insulation tested for asbestos (it was ok, no asbestos) and explained the timing with the electrician. Extremely helpful. Then the 3-person team led by Julio came out and did the job this morning. Incredible. They cleaned up on their way out. I recommend 100%.

As we were selling our house, we learned that the attic had a big mold and rodent problem. We got several quotes, but Insulation Co gave us by far the best one, in terms of price but also in terms of giving us confidence that they would do a good and complete job. Jo is very knowledgeable and efficient. We were not disappointed. The crew was professional and fast, and they went over and beyond to find the root causes of the issues, and addressed them. Thank you Jo and Rafael for a job well done!

Highly recommend Insulation Company. The crew did a great job and left the work site completely cleaned up. Project was difficult to access crawl space in San Juan County. Great documentation via pictures of work done. Office support outstanding as well. Scheduling was easy and there was flexibility when our contractor schedule required changes for the insulation work.

We were in a rush and Jo came to the rescue. Replaced about 1600sf of insulation, treated all wood for organic growth prevention and did it cleanly and effectively WITH a warrantee for a free return visit. Highly recommend!

It was great working with Jo and Insulation Co. They gave me a quote over the phone for cleaning out my crawl space, sealing it, and replacing the insulation. Jo patiently answered all my questions. The crew showed up on time, got the job done in half a day, and did a great job. I'll happily turn to Insulation Co for my next job like this and reccomend them to others.

Jo Estrada, owner of Insulation Co, was very knowledgeable of different types of insulation, and what would be best for our home. His crews are on-time, smart and careful. This company is great!!

Jo communicated so clearly and in detail about their attic mold abatement process and what we are getting for the money. Their crew was efficient, on time and cleaned up perfectly. I'll definitely work with this company again at our rentals.

Great service all around. Coordinating a quote and explaining the situation about our crawlspace was handled with Jo. His quick replies were thoughtful and gave me further confidence throughout.

Cost was right in line with expectations. The team was courteous, clean, and efficient, taking a few hours to complete. Would definitely recommend Insulation Co and Jo's extensive knowledge and communication.

The insulation company is really good. They arrived on time, they were fast, made sure they kept everything clean and when completed it was really good. They made sure everything was clean. Great job.

I’m a realtor and called Insulation Co to help with a crawl space insulation replacement on a home I was selling for a client. They finished the job quickly, and efficiently with the best customer service and minimal fuss. Thank you to Joe and his team!! Here’s before and after photos

Jo and his team worked on our crawl space under the house. They replaced the plastic, checked for water, replaced screens, removed the insulation and replaced all of it. It was tied up and fresh. They did an excellent job and I highly recommend them. The price was reasonable and it looked fantastic when they were done.

Showed up on time. Did a great job. Would have him do work for me again

Jo and his team were very nice, informative, honest and easy to work with. The cost was half of other estimates received and they were super fast and did really thorough work. We are very happy!

We had a rat infestation that did significant damage under our house. Jo's team came out and took out all the insulation, vapor barrier and then cleaned out everything. They were on time and went to work straight away. I was very impressed with the job! I highly recommend them to anyone in need of their services!

Best contracting experience I’ve had in a long time. The bid for the job was excellent with a considerable rebate. Jo the owner kept me informed about the job from start to finish. I’ve already recommended them to all my friends. Will use them in the future.
