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

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

"I did not end up using Andy for reasons outside of him but he would be the first person that I would use and call in the future."

"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 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."

"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."
