    If you’re a homeowner in Tacoma or anywhere in Seattle’s King County, you know our weather can be a real headache for foundations and concrete. 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.

    Sam was amazing. He provided 4 different options and let me know the price ranges to work with my budget.
    Seth C. was really helpful this morning. It has been raining so much lately and he was able to walk me through all the issues my daylight basement and garage can have and how TerraFirma fixes them. Really appreciate you--/thanks so much Seth
    Update: they sent someone back out to inspect the tree and work. Wouldn’t pay for someone to make the tree look nicer and mentioned they could give us a gift card or something for the trouble but never followed up with that. Ended up hiring an arborist on our own. Estimator Derek was very friendly and helpful. Had a much better experience with him than I did with Groundworks. Quote was better too and took about a week to get on the calendar. Was able to get on the schedule fairly quick and they even called with a same day cancellation the Friday before we were scheduled. Work that was done was okay, they were able to lift what we wanted on the main driveway and did their best in front of the steps. Unfortunately they used a jack, which I wasn't expecting, and ended up cracking the slab in front of the steps. It's in the contract that they're not responsible for this so nothing was done to mitigate it. Also a slab next to the large one lifted developed a large crack after they applied the stabilizing foam to the lifted slab. Other issue is that they said it wouldn't be an issue to have the truck down our driveway as they have more than enough hose to work with. Unfortunately they backed the truck right into our magnolia tree and when they were pulling away it ripped a large chunk of branches out.
    I had an excellent experience with Seth from TerraFirma during the field review of my home. He was punctual, professional, and extremely knowledgeable about every aspect of the house. Seth took the time to explain what he was seeing, answered all of my questions clearly, and made sure I fully understood the condition and next steps. It’s rare to find someone who combines expertise with genuine care and attention to detail, but Seth absolutely delivered. His professionalism and confidence gave me real peace of mind. I highly recommend Seth and TerraFirma to anyone needing a thorough and trustworthy home field review.
    Noah with TerraFirma is very knowledgeable and walked us through all options. Answered our questions and I greatly appreciate all the visuals for options presented. I would recommend Noah to work with!
    Seth came out to evaluate my foundation and gave me one of the most thorough and honest assessments I've experienced from a contractor. Professional, communicative, and zero pressure — he clearly takes pride in his work. I didn't move forward with the project through Terra Firma, but that has nothing to do with Seth or the quality of his visit. Highly recommend requesting him specifically. 5 stars.
    Schylar did an outstanding job. Very knowledgeable and helpful. Very happy with the results.. Thank you Joe Henslee
    Just a real pleasure to do business with. The System Design Specialist is very professional. And very thorough. Hailey Newman Is AAA+++ amazing! Everything explained in easy to understand terms. I really could not feel more confident about my issues and my options.
    I am very pleased with the completed work raising the back door porch entry, they were on time, very polite and professional, had all the tools and equipment to do the job.
    We worked with TerraFirma on a complex project involving installation of their EverBrace wall stabilization system. The project took a lot of planning and communication leading up to installation, plus a 3-week on-site job. Everyone I interacted with at TerraFirma was warm, communicative, respectful, helpful, and creative in solving any issues that arose. I could not have asked for a better customer service experience. Our project was expensive, and a stressful endeavor for a homeowner, but I felt I was in good hands from start to finish with TerraFirma. Not to mention that the EverBrace solution saved us tens of thousands of dollars. I highly recommend this company.

    Even though we’ve been crawling into musty crawlspaces and wet basements for over 20 years, we love the Pacific Northwest.
