    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.

    Absolutely Great Crew-Jorge,Juan and Manuel! Very Professional. Answer all my questions as they worked my Project. Very well organized. Used all the proper safety gear to remain healthy and virtually encapsulated with plastic the interior of my home to contain the dirt/debris tracked in from outside/under the house. They helped set up the electronic gizmos to my WiFi so I can monitor the system they installed. Very happy with the results.
    Didn't end up choosing TerraFirma for the work we are doing but they were very professional and helpful through the whole process, especially our rep, Bailey. Recommend including them in the bids you get if you need foundation work.
    Elijah did a fantastic job breaking down everything going on in my crawlspace and providing the estimates to get the repairs.
    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
    Very knowledgeable and professional
    Good customer service, good quality work and timely.
    2/16/26 update: My sump pump broke in December due to the high level of iron in the soil under my house. Terra Firma responded quickly and replaced the pump with no issue. Great customer service and a great team / experience! Thank you Terra Firma!

    Seth has been amazing to work with! I have been working with Seth on designing my crawlspace drainage system. Seth has been extremely helpful, patient, and professional. I've pestered him every day, multiple times a day with questions, asked for revisions to my quote, clarifications, and have been an all-around pest. Through it all, Seth has been responsive, communicative, and thorough. The work is scheduled for Mid-May 2024. I will update my review after the work is done with how it went with the crew and the job they did.
    Although TerraFirma wasn’t able to assist with my specific concern, Bailey was extremely professional and thorough. I would definitely recommend having them evaluate your next project.
    I had a very positive and honest conversation with Bailey regarding leveling my front walkway. He performed a thorough inspection and explained the outcome of the inspection and the method of treatment. Ask for Bailey!
    Bailey came out and did a thorough walk through, listened to my project plans, was very helpful and polite!

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