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.

    These folks are WORTH the call and having them out! Seth, specifically, was amazing at scope, plan and presentation. He was so knowledge and really took into account all of the needs of the house structurally and visually. He was extremely professional in house and on the phone. Nothing was over sold or up sold, and every concern I had was listened to and taken into account. Every detail was in the bid neatly and nothing was out of place. If you've got a basement or crawlspace project, this is as professional as it gets. I will DEFINITELY be keeping this company in mind for future projects and for friends and family. Call. Ask for Seth. He's got you.
    Initial inspection and determination person was a very good listener and made good suggestions. The work was performed by an excellent technician with good experience. He explained the process and gave helpful advice. Great value for the money.
    We had Terra Firma lift an RV barn that had settled over 3” in one corner causing a large crack in the concrete floor. The first crew consisting of Mike, Steve, Jeremy, and Preston installed helical piers and righted the building back to level. Schylar then came and installed the poly foam to stabilize the floor system and insert Nexus to fill the cracks. All workers have been very competent and professional and are hard workers. They are responsive to questions and concerns and have treated us very well. Co-ordination of the work was done by Mechele from her office in Roseburg. She has also been a joy to work with in ironing out any problems or concerns we’ve had with the job. Salesman Morgan is a good ambassador for the company and all the work was completed as promised by him! All in all, we are very pleased with the outcome! Mark R
    TerraFirma responded quickly to our call. Came out for a free evaluation of our foundation . Seth was very friendly, professional, and obviously well knowledgeable about his trade. Within 2 hours we had a very thorough assessment of our foundation. Thank you TerraFirma, and Seth.
    I did a ton of research on TerraFirma when I decided to pursue getting a seismic retrofit in my basement, and then to clinch it, my Engineer neighbor spoke highly of them as well, stating they are top tier in their field. Jake's Crew came out today to review, and instead of selling me on a $10,000+ price tag, educated me on why they were unable to do the retrofit - my foundation is hollow concrete, their drilling would shatter it, and their alternative wouldn't meet my required needs. Honestly, I'm BLOWN AWAY how awesome Jake's Crew was - honest, direct, helpful, and educated me on my foundation. They even cleaned up under the porch for me, graciously turned my outside water off under the crawl space (thank you!!!). I'm so sad my foundation isn't able to be seismically retrofitted but I'm ridiculously grateful to Jake's crew for being so honest. I highly recommend TerraFirma - I read a ton of reviews on multiple platforms, and when they do make a mistake they fix it and make it right. They are full of integrity, and I'll forever remain impressed and won't stop recommending them to anyone/everyone!
    These guys replaced the foundation along one whole side of my house. Then they installed a drainage system and sump system beneath my home. I couldn't be happier and it was worth every dime I paid! Great work, great crews, great subs, everybody from the switchboard to the project managers are the utmost in professionalism. If needed I'll hire them again.
    Seth gave me all the information on how the process works and my quote on the spot!
    Robert and Elijah were wonderful - set expectations great communication professional and friendly
    Shout out to Shane A!! Shane came out to inspect and bid our office crawl space/foundation/sub floor. (A repurposed residential home). Shane was awesome. He gave me straightforward honest info. He came during business hours and clearly did all he could to avoid interrupting our work flow. Shane was kind, pleasant and above all, honest. Shane sent our bid the same day. He just for the problem we call about, but checked the entire space. I called the next day to schedule an appointment for the work Terra Firma's crew came out within few days. The work crew was on time!! They even assisted one of our older employees across our icy parking lot. The whole crew was polite, pleasant, quiet, and fast. The crew was also here during business hours and we barely noticed they were here. I was very impressed with the ENTIRE process and highly recommend giving them a chance to earn your business. I have worked directly with clients and customers for over 30 years, in both small and medium sized businesses. I am extremely customer service oriented personally and professionally. I provide great customer service and in turn expect it. I am not easily impressed. Terra Firma impressed me. I don't write many reviews. The experience must REALLY good, or REALLY bad, for me to take the time to write a review! Terra Firma was REALLY GREAT. Thanks Shane and crew! Ron B We The People Law Office
    Bailey demonstrated exceptional attention to detail and expertise when inspecting the house foundation, ensuring everything was up to code and structurally sound. He addressed the issues I was concerned about and was very honest on his findings.
    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.
    The team that came out was hard working, considerate and very professional
