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

"Excellent work, all around! The crew was hardworking, and the work performed has stood the test of time. Three years ago, Wu Construction expertly installed a full crawl space perimeter footing drain, brought in drainage gravel, and installed a 1/3 hp sump pump. Also installed a 6 mil black vapor barrier, checked and sealed alle entry points to prevent rodent entry, re-installed all loose inulation and replaced heat duct insulation. The crawl space has remained bone dry, and we've had no further issues with moisture or rodents."

"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."

"Everything went as planned. The came on time, cleaned up afterward, and even patched a crack that wasn’t part of the original contract. Didn’t even ask them; they offered. Super happy with the result. I’d hire them again."

"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."

"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."
