We did a full house remodel and, unfortunately, had to redo several areas due to the poor-quality subcontractors hired by our general contractor. For the insulation work, we decided to go directly with Insulation Co. and had them remove the old insulation from our attic. Since we were also doing extensive HVAC work, this made the entire process much smoother. The owner was fantastic to work with, accommodating our schedule when we were ready to install the new insulation. The work was impeccable, and we will definitely hire them again in the future. Highly recommend—Thank you, A+ service!

Great Service, had crawlspace insulation done last year. I did not want to rush with a review and wanted to give some time before I rate the service. The work they done was great and on time. Also Jo was great and flexible to adjust the schedule to fit my re-ducting work in the crawlspace. Highly recommend !

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!

Jo and his team did a fantastic job had a lot of bird nesting debri in the attic. They did a wonderful job cleaning it up sealing the attic space so the birds won't be a future problem and get new insulation taken care for my house. Right on time, quick, great clean up when done!
