    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.

    Fabulous company to work with.
    Excellent Choice
    Bailey Mercer-system design specialist made a visit to my home to provide an estimate for foundation work. He was professional, well-mannered and easy to talk to. Assessment was thorough with all my questions being clearly answered. Great experience overall!
    Because of settling, the concrete porch was pulling away from my house. The TerraFirma sales rep who came out did a great job of explaining the Polylevel procedure. The crew was extremely polite and respectful, completed the job exactly as expected and the area was completely clean when they left. I would have no hesitation using TerraFirma again.
    I met with Noah today, with TerraFirma. He was personable, a good communicator, an excellent listener, patient and knowledgeable.
    We all know home improvement is stressful. Seth from TerraFirma really helped out. He communicated along the way, called to let me know he would be arriving shortly, and just had the super calming energy to himself. That was helpful cuz dang, I'm intense, I admit it. Will definitely be calling him for any future foundation needs! Thanks Seth!
    For Seth Cunningham: "You never get a second chance to make a first impression." Terrafirma should be very proud to have Seth Cunnigham as their first impression. Punctual, professional, personable, and very knowledgeable. Seth assessed our crawl space and provided us with a thorough explanation (photos) of the situation, options (videos) and itemization (documentation) of each potential solution. He is a delightful young man who I would recommend without hesitation.
    During my search on-line for a source of repair for cracks in our cement driveway, I found the TerraFirma Foundations Systems website most appealing. I invited Seth, Systems Design Specialist, to provide an estimate. He provided a thorough explanation of TerraFirma's method for repairing cracks. He examined the driveway, made the necessary measurements, and provided a reasonable estimate--considering the extent of the current damage. The project was scheduled to be accomplished in two phases. Phase 1 scheduled Nov 2024: foam injection to stabilize the cement pads thereby preventing further damage. Phase 2 scheduled May 2025 or sooner depending on the weather. This delay was a consequence of my procrastination to tackle the project earlier and TerraFirma's determination to ensure the repair would suffice to fulfill their 5-year warranty. Employees Robert and Elijah arrived on the scene as scheduled. While I observed their work, they impressed me with their professionalism and efficiency as an experienced team. They put forth an obvious desire to do an exceptional job thereby giving me confidence in the performance of the task and TerraFirma overall. Standby for my review this summer regarding Phase 2.

    They did a great job! They kept in touch throughout the entire work.
    Great worker Seth Cunningham, gets down to the nitty gritty, takes a full inspection on the problem, does not do just the minimum, he goes above and beyond to figure out the problem.
    Bailey came out and did a thorough walk through, listened to my project plans, was very helpful and polite!
