Get matched with top foundation drainage installers and replacers in Mercer Island, 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."

"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."

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

"Chris and Amanda are absolutely amazing.Amanda described in detail layer by layer step-by-step. And they kept me in the loop every step after the project started Making sure everything was to our liking. I couldn't upload the picture before but it was dug up dirt and lawn per our dogs. And now it looks absolutely beautiful ...reasonable prices and honedtly I was just completely blown away With the whole thing.. definitely going to hire them again for future projects. And this isn't the only thing they do ..They do hvac house building any and all landscape outside of the house, and I'm sure there's more. If you need them, they are your people, don't pass them by you'll be missing out if you do"

"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."

"We hired Curry Landscaping to install some French drains. When doing the estimate, we were given a very clear explanation as to what would be done and the cost. He was able to identify what was leading to a lot of the ponding in our backyard and create the drainage solution. Very pleased with the work and the price."
