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

"P4 construction came out to work on some drainage work I had on my property. They did a fabulous job. Highly recommend."

"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."

"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."

"We got a bid from Andy Construction for water-issues in our crawlspace. Of the companies that I talked to about this issue - I thought Andy provided the most objective recommendation (though it costed lesser). Other companies were recommending a sump pump. Andy recommended addressing the source of the water (downspout drainage issue). We haven't yet gotten the work completed, but would recommend Andy Construction based on the bidding process."

"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."

"Iron Earth is the complete deal. They took down an 70 yr old garage that had seen much better days and replaced it with an exciting new garage and RV Port with a storage loft. Dan Faris and his crew did a marvelous job of tackling every step of the process; from planning, permitting, design, teardown, removal of old garage and every facet of the build. Unlike some contractors I've experienced in the past, he listened to our wants and needs. Discussing what could and couldn't be done while providing the details. I knew they were offering us to be partners in the process, not telling us what the project would be like others had. The team was professional and reliable i knew I could trust them in every facet. Iron Earth Construction and Dan Faris will be my go to for future projects, as I know I can rely on them."

"This is the second time we've used Rain Pros, and they delivered outstanding results. Our first experience with them was to replace our underground downspout system, and they exceeded every expectation. Naturally, we called them again when we needed additional drainage work, and they didn’t disappoint. Water accumulates in one area near our carport. Based on our great first experience, we didn’t hesitate to contact Rain Pros again. Like before, their quote beat everyone else — offering high-quality solutions at competitive prices, which is almost unheard of in this field. Joel and his team kept the worksite clean and organized, carefully protecting our landscaping and leaving the area spotless once the job was done. This is attention to detail and professionalism. Rain Pros has proven to us twice now that they are reliable, skilled, and affordable. They should be your first call if you’re in the Northwest and need drainage solutions."
