Get matched with top foundation drainage installers and replacers in Bellevue, WA

"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."

"We had pest and ant problems in a 1930’s home we recently purchased. It had been vacant for some time. Part of the solution was to redo the crawl space. Andy Construction gave us a very reasonable quote for removing what was there and installing the vapor barriers, replacing spotty floor insulation, sealing cracks and new access doors. The crew was courteous, on time, and left no mess. We haven’t seen a mouse since and the ants are getting under control. Our floors and home are so much warmer! We heartily recommend Andy’s Construction."

"Wyatt, Zane, Tucker and Oliver were fantastic. Customer service was fantastic and they finished their work quickly and professionally. I'll definitely be recommending and contacting for any drainage needs down the road."

"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."

"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."
