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.

After looking for a escapee cat, I discovered the insulation in the crawl space was, like, awful. I phoned Joe, who answered instead of the dread voicemail and we were able to work out an estimate over the phone with the magic of tech. When the day came, the two installers were as good as anyone could be, no mess, no fuss, competent, friendly as well as leaving the outside of the house looking like nobody had been there. They shared pictures of the work which looked over the top, saving me the trouble of crawling under and having a look. I'm really glad it worked out and will highly recommend anyone looking for attic or crawl space insulation to Joe at Insulation Co.
