I was referred by a local contractor. Customer service was great. Phone call resulted in quick proposal emailed. Once accepted, work scheduled timely. Crew showed up as stated in scheduling. 4 1/2 hrs later, job complete. Crew was friendly & cleaned up all debris. I am very happy w/results. They helped me with applying for gas utility rebate as well.

Removed old fiberglass insulation that at one time was rodent infested. Removed old plastic ground cover sheeting. Installed new ground cover black plastic sheeting and new fiberglass insulation.
This was in the basement crawl space in my 9-unit apartment building. Very satisfied with the work - they were very responsive to some follow up work - would definitely recommend .

Jo was a pleasure to work with. He was very knowledgeable and professional. Bid was very reasonable, I had 2 other bids and they were the best overall. The workers arrived a few minutes early which was great & did the work in a very timely manner. I had my crawl space done. Removed all of the old insulation and vapor barrier, sanitized, rodent proofing and reinstall insulation and barrier as well as the access door.
Would highly recommend, a pleasure to do business with

Blown In Insulation Install or Upgrade
Insulation Co (Jo Estrada) had insulation installers come to our century old house to remove old attic insulation, do a bit of mold remediation, insulate the bathroom fan exhaust, cover the two previously open gable spaces at either end of our roof, then blow in new cellulose insulation. All this took a day, and all was cleaned up like nothing happened. Polite, efficient, professional, and the price was competitive.

Jo was super responsive and professional. They understood the work that needed to be done - had completed for others in our neighborhood - provided a clear plan for the work and a quote. They performed the work as proposed on time. I would use them again and recommend them.

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.

Foundation, Basement or Crawlspace Waterproofing / Encapsulation
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

Foundation, Basement or Crawlspace Waterproofing / Encapsulation
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.

Blown In Insulation Install or Upgrade
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.

Foundation, Basement or Crawlspace Waterproofing / Encapsulation
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

Sump Pump or Interior Foundation Drains Installation
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.
