    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.

    Seth was helpful and informative. He was able to come evaluate the project right away and provide solutions to the issues.
    Very helpful, and very very inexpensive, they actually did not charge me for the help they gave me, that is hard to find these days!
    Terra Firma did an excellent job on our porch beam & supports repair. Their estimator was especially helpful. The workers were very nice & worked hard. We appreciate Terra Firma’s diligence to safely do our repair. We would highly recommend Terra Firma. Thank you.
    Every person I had contact with was fabulous. Pretty fair price too
    Had the best experience with Terra Firma. From representative Kris, coming to give us a quote and setting everything up, to the crew (Foreman Albert and his crew) who came out to do the encapsulation of our home crawl space. The team members did nothing but the best to make sure the work was don’t correctly and with pride. Thank you!!!!
    Noah came out to look at some floor sagging and to check for other foundation issues. He was great to chat with, thorough in his inspection, and did a nice job walking through his findings and the options. While we did not chose to move forward with any of the plans at this time, the company was prompt and Noah was wonderful, so recommending them as a company to reach out to if you are collecting quotes.
    Bailey was the best! So knowledgeable and helpful! Also, very understanding & caring! So good at what he does!
    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
    Terra Firma is great to work with. They have an excellent crew. They were polite and very knowledgeable of what needed to be done on our foundation repair. I would gladly recommend Terra Firma.
    They were able to change up the project to what it needed to be and still got it done in a timely manner
    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.
    Seth had been very knowledgeable and exhibited wonderful customer service when helping us with the beginning process of our new home's crawl space
