We used terrafirma to both waterproof the entire basement AND lift the foundation. 10/10 would recommend. extremely communicative, very knowledgeable, and even brought a crew in from Oregon to help us stay on schedule. Oscar and jorge got the job done extremely quickly and Seth was fantastic as my project manager."

"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."

"Iconiq Construction Service did an amazing job finishing our basement. The team was professional, efficient, and detail-oriented. The results were outstanding, creating a functional and beautiful space. Highly recommend their services!"

"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."

"URM Constructions did an excellent job repairing my roof. They responded quickly, explained the repairs clearly, and completed the work professionally. The crew was punctual, courteous, and paid attention to every detail. They fixed the leak, replaced the damaged shingles, and made sure everything was sealed properly. The quality of workmanship was outstanding, and they cleaned up thoroughly when the job was finished. The roof looks great, and I have peace of mind knowing the repairs were done correctly. I highly recommend URM Constructions for any roof repair needs. Reliable, honest, and professional service from start to finish."

"They quickly assessed the situation, gave a reasonable quote, and were very proficient and professional. My condo unit was under contract and a water leak caused by another unit needed to be repaired asap and they did it. Also kept me well informed."
