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."

"Urban Drainage & Masonry replace the chimney on my house. They did an excellent job. They arrived on time. Finished in one day and cleaned up when the job was completed. They were also very professional and respectful. I would highly recommend them."

"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."

"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."

"You wonâ t find a better operator in the area. Experienced, knowledgeable, trustworthy, and professional."

"We had a damp crawlspace. John's installed drainage with sump pumps (lead and backup with battery backup power) and encapsulated the dirt with 20 mil plastic. They also installed PU foam around the perimeter foundation walls to complete the insulation envelope of the house and a dehumidifier top keep the crawlspace area dry. In short, this work solved the problem we had and provided the added benefits of a more energy efficient and comfortable house due to the insulation as well as better indoor air quality. The work was done in four days and at considerably less cost than a competing contractor bid to do it. Another person that we had inspecting house later looked at the crawlspace and commented, "Wow! You could do brain surgery down here." We actually wouldn't recommend that though ;)"

"Extremely processional and responsive. Tru Terras was on top of all my landscaping needs. Highly recommended."

"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."
