    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, Bree and Angel were fantastic to work with! Thank you Terra Firma for helping stabilize our cabin. Professional, on-time and kept us informed of all the steps that they were taking and why. Up front pricing, no hidden costs and a job well done! Very Satisfied customers! Highly Recommended.
    Seth came over and had a look at my foundation to give me a quote on some work. I was incredibly impressed by how thorough he was with his inspection of my property and the knowledge he had to help me assess the condition of my foundation. Would highly recommend
    I used Terrafirma for foundation support repair. I found the staff and work crew very honest and extremely thorough! Was a little outside my budget, but I was so happy that I chose them! Satisfaction in every area is so worth it!!
    Will choose them over and over and refer!

    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.
    While I did not choose TerraFirma for my project, it was still a very positive experience. I would definitely call them again if something came up in the future. From scheduling through the bidding process, they were responsive and organized - seemed to have all their ducks in a row. Bailey came out to inspect and put together a bid - he was on time, incredibly organized, thorough, knowledgeable, friendly, and communicative.
    We worked with Seth Cunningham from Terra Firma in Tacoma and he was a consummate professional throughout the entire process.
    We recently decided to sell the home and Seth offered to speak with the buyers about the work they did and the transferable warranty. This gave the buyers the confidence to move forward with the purchase. Many thanks Seth!
    I could not be more impressed with how informative, respectful, and honest Bailey was with my parents. He took a very stressful and emotional time, and eased their fears and took the time to really explain and educate them on the best option for their property. I am so grateful!
    Bailey was the best! So knowledgeable and helpful! Also, very understanding & caring! So good at what he does!
    Hey Folks, So just over a year ago we were having some issues at the house, I wrote to all of you on how wonderful TerraFirma was to us and I am here to tell you... THEY DID IT AGAIN! I starting noticing some movement in the driveway and inside the garage again. Called up Bree in the office and asked to have someone come take a peek. Edwin came out, what an awesome dude! Edwin spent a short time at the house remeasuring a couple things to compare back at the office with measurements from a few months ago, We heard from Bree that the measurements were still within reason. I let Bree know, something is not sitting well with me and I really would like to chat with the Mgr. So I received a call from Tulane, Again SUPER DUDE! Tulane assured me with my husband present that I am not being in any sorts a pain, I have concerns and he and Sam, who came out in 2024 will come to the house.

    Well they came, they saw, Oh Boy! I was not wrong, they were here 2.5 hrs and again, the house has had some movement and we need some more work to stabilize. We have some additional C.Y.A's to add to this round, as our neighborhood and home has lots of sand in the soil so we are going to be looking into getting a GEO Engineer out to see what is causing the movement.

    I give all the back info, because I want you all to know, if you feel something is not right CALL and have your home looked at. TerraFirma is NOT redoing what they already did, this is all new issues, not their fault at all... Tulane and Sam are amazing, they took the time to explain and give us all options. The info they share through experience and knowledge is beyond me and it is so appreciated.

    If you have any foundation, sinking driveways, walkways, stairs, cracking in your walls, around windows, doors.... Call these guys!
    I hands down don't always do reviews but I do for these guys because they deserve to have their names out there so you know they are TAKING CARE of their customers the whole way through! 10/10 and then some.... THANK YOU!
    Had a great experience with Derek Ryan…very knowledgeable, professional and explained everything to our satisfaction. He also provided follow up support, which was much appreciated!
