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

"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."

"Eric was completely responsive to the problems we needed to address and was very attentive to the concerns we expressed. He showed up when expected (and needed) and worked straight through to completion. Our sump and drainage issue is resolved. I appreciated the explanations he gave of what was happening and what needed to be done. I also appreciated his clear explanations of why the â right wayâ to fix something was better than the â jury riggedâ methods that had been done in the past."

"Our house is almost 130 years old, so we needed to have some foundation stabilization done. The company was a pleasure to do business with. From our initial consultation and beyond, every contact was courteous and knowledgeable. On the first day of the project, after removing the dirt to see the foundation, it was discovered that the existing foundation was not sufficient to support using the helical piers according to the building inspector. The dirt was all replaced and it was arranged to come back out and give me a quote for a different process using smart jacks. Due to circumstances at my local building department, the new job had to be postponed until a new permit could be obtained. Once that was done I was rescheduled and the job was completed in a day and a half. When the building inspector came to sign off on the permit, he raved at what a great job they had done. I would definitely recommend them to anyone who asked."

"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."

"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 ;)"

"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."

"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."
