All that rain soaks into the ground, putting pressure on your foundation walls and leading to cracks and leaks. Our geologic conditions here double down on the problem with expanding and shrinking soils, causing concrete to crack, lift, and sink.

    Don’t take our word for it – see what our clients have to say.
    From Bellevue to Kirkland, Tacoma to Kent, and throughout King County our work speaks for itself.

    Quinten was awesome. We weren't home when he showed up. I though we would have to reschedule but Quinten waited and was very pleasant about our delay. He made sure everything was working and explained the system to us. Thank you Quinten for coming out today and sorry again that we were late. Will recommend always to friends and Family.
    The project was completed as described and the crew very professional. The cost I think, was reasonable. The only thing that was not clear after the initial assessment and explanation of the project was that not only would the drywall would be removed, but also the framing studs and floor plate. This added to the cost because those needed to be replaced by another contractor.
    Best customer service in the northwest !
    So thankful and appreciative for the help while I was out of state .
    We have had thoroughly excellent service from TerraFirma since October, 2017, for a variety of issues involving flooding and foundations. TerraFirma seems to us completely competent and reliable. We would recommend this company to one and all.
    Seth. Was great. Very. Professiinal. Thank you Terrafirma Vince
    While I did not choose TerraFirma for my project, it was still a very positive experience. I would definitely call them again if something came up in the future. From scheduling through the bidding process, they were responsive and organized - seemed to have all their ducks in a row. Bailey came out to inspect and put together a bid - he was on time, incredibly organized, thorough, knowledgeable, friendly, and communicative.
    Seth, Bree and Angel were fantastic to work with! Thank you Terra Firma for helping stabilize our cabin. Professional, on-time and kept us informed of all the steps that they were taking and why. Up front pricing, no hidden costs and a job well done! Very Satisfied customers! Highly Recommended.
    I could not be more impressed with how informative, respectful, and honest Bailey was with my parents. He took a very stressful and emotional time, and eased their fears and took the time to really explain and educate them on the best option for their property. I am so grateful!
    Great job Thank all you guys TerraFirma👏 keep going
