"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."

"We are happy with their work and service to repair a room with a sinking foundation. They installed push piers and smart jacks to stabilize our foundation. They were patient in explaining the process, their work was of good quality, and they finished within the stated time period."

"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."

"Very efficient. Finished job ahead of my expectations."

"Did great job of installing toilet. will be calling again for future work! thanks alot cory & david ."

"I called them last minute and they were very responsive. They sent Aleks out to go over the job with me and then I got a quote later that day. They came out within a couple of days and did a wonderful job. We have a large area and they trimmed all of the bushes in the trees, cleaned up all the beds and mowed the lawn for both backyard and front yard."

"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."
