"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!"

"4.5 stars overall for removal of concrete slab/stairs and pouring of new 10' long, 4 foot deep foundation wall. Result was excellent. Crew was considerate and trustworthy. It was expensive for me, but cheaper than the other bids I got. Communication was not great over email. There were a number of times I wasn’t replied to at all or got a partial response. I let them know and they said they’ll work on that. I recommend communicating via text instead which worked much better."

"Outstanding work and value. Andy was quick to respond and came out the next day to assess what we needed to do to improve the drainage in our crawlspace. The home is built on a sloped lot. Andy suggested a full perimeter drain install around the foundation. The work also included complete replacement of the vapor barrier. All work was performed efficiently and Andy backed it up with a lifetime warranty. I couldn't be happier with the end result and would highly recommend Andy and his crew."

"This company is built internally the right way. Extremely professional and everything is in house. I repeat...IN HOUSE. If you have ever dealt with a remodeling company that employs outsourced labor, it can be a mis-quote nightmare. Other companies pointed me to handy men for this job not realizing I might need or want more than that in the future. Thank you "

"We had a foot of water in our crawl space after the snow and 6 in. of rain from the December 2021 storms. I had called several companies to come out to take a look and give quotes. Ethan from diversified was the 3rd quote we received. Ethan explained the issue, explained what they would do to remedy it, and answered all my questions. He sent me the quote which was very resonable. BE SURE TO GET SEVERAL QUOTES. ONE COMPANY QUOTED US DOUBLE OF WHAT WE PAID DIVERSIFIED. They were able to get a team out two days later. The team was on time, professional, and did really good work. We ended up needing a sump pump due to ground water coming up. They applied a mold application and completed the work in a day. I highly recommend these guys and did my research prior to having them do the work. I am very impressed and happy we chose them."
