"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 ."

"Foundation Repairs - We had dry rotted wooden posts due to concrete pads being buried below the dirt. Wu Construction replaced the posts/ piers and placed new concrete pads on top of the existing to raise them above the dirt. I had some questions and Victor Wu followed up with me. Victor is very professional, honest and fairly priced. I would recommend them to anyone who needed these services as well."

"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."

"From my very first phone call, I felt I had found the perfect company to do the job that needed to be done, and I was right. Nikita, the company owner, communicated with me all along the way, so I knew what to expect. Everything was done so professionally from the detailed work contract, the promptness and reliability of the workers, and their special skills in the work that was done. I had the utmost confidence from beginning to end which was very valuable to me because of the urgency and type of work that needed to be done. I live in a manufactured home and my roof/ceilings in two rooms were sagging, and on the verge of possible collapse. Complete truss repair had to be done, and it needed skilled workers to do the job, and do it right. Vytali and Sergey are extraordinary at what they do, and now I have a piece of mind knowing I will never have to worry about those rooms again. I most definitely would use them again, no doubt, and am going to recommend them to friends, family, and neighbors that are looking to have work done. UPHOUSE, LLC is outstanding, and for such a dire situation that I had, they made it as easy as possible, and by far, the best experience I have had with a contractor, ever."

"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."

"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!"

"I hired Urban Drainage and Masonry to fix two issues with my paver driveway and sidewalk: troughs in front of the garage caused by years of vehicle traffic, and a large hump in the sidewalk that made approaching the front door difficult. The contractor identified excess water from roof runoff as the main cause and recommended installing a driveway drain, along with addressing moss buildup on the pavers. The crew worked quickly and efficiently installing the drain. The process freed up pavers that were reused to replace older, deteriorated ones, and they were able to square off parts of the original installation, improving the overall appearance of the sidewalk. They also provided helpful, no‑pressure suggestions for future projects. Overall, their work was professional, thoughtful, and effective, and I would gladly recommend them."

"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."
