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.

    Noah was extremely thorough and explained his findings clearly with optional choices of services that we needed with the pricing. He was friendly, courteous and easy to talk to. We would highly recommend Terra Firma. Noah is a very valuable representative of the company.
    So pleased with the total experience. We were provided with expert analysis of how to achieve stabilization of a concrete slab. Coordination between sales, planning and production was excellent. Technician was very proficient and friendly.
    Seth came out today to check under my house to give an assessment on ways I can improve my foundation for earthquake protection. He was awesome. He was on time and very personable. He explained things (with pictures) very clearly and answered all my questions. I was very impressed. 🙂
    We are impressed with the knowledge and thorough and professional assessment of our home’s issue. Seth Cunningham was great at communicating information and providing answers to our concerns.
    Seth visited our home to give us a quote on seismic retrofitting. He was on time (and made sure to call when he was heading our way), did a thorough assessment of our home, and was an absolute pleasure to work with. During the assessment, Seth patiently answered all of my questions. It was clear that he was extremely knowledgeable about the available retrofitting options and what best suited our home. The final proposal was easy to understand; it clearly outlined the work to be done, why it needed to be done, and how much various options would cost. Overall, it was an excellent experience.
    Quenton came to service crawl space sump. He did a thorough inspection of the whole space. Cleaned and serviced sump that was full of clay. Found issues and gave recommendations with pros and cons. He didn't push any unneccessary things. Took pictures of all issues and work and thoroughly explained everything. Installed a new dehumifier and removed old one and hauled away. Would recomnend this guy to anyone. I hope this guy is an example of how the business is run. Excellent job, very happy.
    I’ve had a great experience with TerraFirma so far. Seth Cunningham is the tech that we have been working with, he has thoroughly explained the issues we are facing with our foundation and the steps we need to take to salvage our home. Although this is a blow to any homeowner, I trust that Terra Firma is going to get us back to where we need to be step by step. Communication has been top notch, and I feel confident we are in good hands…… update!!! The work was completed by the crew, they were so professional and nice. Got the job done and were even able to eliminate one of the jobs because they were able to make it work and they made me aware of a leaking pipe under the house I didn’t even know was there. Invaluable!!! This is a very good company to work with, I really am satisfied.
    I've had multiple interactions and services (including sump pump installation) done by TerraFirma, all good experiences. However our last service which was an inspection of our foundation was exceptional and warranted me to write a review. Our systems design specialist Tanner Heinz who came out was courteous, knowledgeable, friendly, and respectful to our home. We felt like he wasn't trying to oversell, just telling us straight facts and honest opinion. We trust our home is in good hands and came up with a game plan. If I owned a business we'd be lucky to have Tanner as an employee. Highly recommend this company.
    Seth was amazing and really put in the work to figure out exactly what I needed done on my home. He was super knowledgeable and seemed to really care about my needs. I tried 4 company’s before terrafirma and will stop looking as I am sold on their ability and willingness to take care of my family and my home.
    Bailey was timely and thorough in his assessment, estimate, and reporting on my inquiry about a foundation crack. Although I decided not to have any work done at this time I was pleased with their service.
