New to the state, not sure who to use for the attack and crawl space clean up, sealing, and institution replacement. Joe was very helpful, his team was awesome and they did a great job. Highly recommended using Insulation CO if you are looking for attic and crawl spaces work needing to be done.

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

Jo and the team at Insulation Co. were recommended to me by a neighbor who had to have their crawl space cleaned out due to rodents. After inspection, turned out I also needed to have mine cleaned out and I was extremely happy with the work done by his team. Quality work, competitively priced, and prompt clear communication. Will certainly use them again, and confidently recommend Insulation Co.

We had Insulation Co remove and replace our blow-in attic insulation as a part of a larger electrical project. Both phases of the insulation work went quickly and smoothly. Better yet, Jo from the company was incredibly responsive and kind in his communications with us which is a big bonus for first-time homeowners still learning how a lot of this stuff works. Our family recommends Insulation Co should you need similar services.

These guys were great, and the owner, Jo Estrada, a pleasure to work with. A crew of 5 spent 5 hours cleaning, inspecting, and replacing insulation and vapor shield in our crawl space. They took pictures of everything, before and after. THe crew was pleasant, and worked really hard.... couldn't believe how much stuff they removed from under there. The crawl space is tight, but they didn't complain (at least to us!). They gave us good recommendations for some repairs needed for the foundation. All for a most reasonable price, compared to other estimates. They deserve every star they can get!

Insulation Co. showed up on time and removed and replaced the insulation in my client's attic and crawl space. They were hard working and professional and were very careful protecting the carpet and flooring and cleaning up after the job. I would highly recommend them!

Insulation Co replaced my worn crawlspace insulation in late 2024. They communicated well, came when they said they would, and cleaned up after themselves. I used to work with a municipality monitoring weatherization work so I know a bit about it. I was very impressed with their final result (yes, I crawled around down there).

Jo Estrada and his workers were easy to work with and Jo always got back to me right away when I needed to talk with him. His price was fair, and his workers went the extra mile to get the job done right and they were always courteous and respectful. Insulation Co. LLC is a company you can hire with confidence, knowing you are dealing with someone who will treat you well, like they care about having a good, positive relationship with you and getting your business again if you need it. I'm very glad that I found Insulation Co. and would happily recommend them to anyone who might need their services. Richard in Seattle

Water had always been a problem for my crawlspace, especially during raining and snowing season. Asking around, installing a French drain and a sump pump appeared to be the solution. I searched around and picked Insulation Co. Estimation without inspection seemed weird at first, but it made totally sense since the foundation layout is all there in the files. Jo had always been responsive, detailed and nice whenever I had questions. Scheduling was easy and Rafael and the team did a great and efficient job onsite. 2 months after the installation, we noticed that there was still standing water and they came back to install more pipes and gravels. We really appreciate the effort.

Insulation Co stood out far above the other two bids we received. 1. RESPONSIVE – They answered calls immediately or returned them within 30 minutes and always followed through on commitments. 2. EXPERTISE – Guided us through attic and crawl-space insulation options, clearly explaining tradeoffs and demonstrating deep knowledge of building codes. 3. REBATES – Proactively estimated the rebates we’d qualify for and connected us with their utility company contact for verification. 4. EFFICIENT – Used public records to pull floor plans, delivering a highly accurate, itemized bid without needing a site visit. 5. TOP-NOTCH CREW – Their six-person team arrived on time, did outstanding work, and even sent us photos of the completed job. Highly recommended!

I would recommend Insulation Company with hesitation. We had an issue with mold in our attic and rodent damage in our crawl space. Insulation Company did exactly what they proposed to remedy the problem and did it on-time and on-budget. The 12-man crew were very profession and polite. The level of care they took to protect our home was over the top. They treated it as if it was their own. This was a job no home owner every wants to encounter and they made it very painless.

I went out to three separate vendors for quotes on new attic insulation and mold remediation, Insulation Co was by far the cheapest of the three. In discussion with Jo (the Owner) it was clear he knew what he was talking about and cared about us his customer. The day of installation couldn't have gone smoother, the crew was punctual and very friendly. The work itself was done professionally and throughout the whole experience communication was clear. Couldn't recommend these guys enough.

Jo and his team at Insulation Co. did a great job! From the start, I could tell I was in good hands: - I called and left a message with my address and issue (mold in the attic due to a detached stove vent). - Less than an hour later Jo called back. He'd looked up my property on the publicly available city records, so was able to put together an accurate estimate based on my home's sqr ft. - Then Jo walked me through the steps, the equipment, and the timeline. He followed up soon after via email with all the info we'd discussed, plus links to YouTube videos with additional information about the process. He included a line-itemed estimate/contract with clear terms. - On the agreed date, his team showed up on time. They were courteous and efficient, and finished the project later that afternoon. The project lead had taken photos throughout the process and walked me through the work they had completed. They did a great job cleaning up too. Cannot recommend enough!

Insulation Co was quick and thorough. We needed a job done quicker than most. They remiediated our entire crawlspace and replaced our ducts. They made sure to get us on their schedule immediately. Jo even went out of his way to be available to me while he was out of town. They finished everything in less than a day for each job with excellent precision and kind workers. They were also reasonably priced! I would highly recommend them to everyone.
