    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.

    Five stars aren't enough. We had a sizable project on an old house in tight quarters with neighbors who were concerned. We knew going into our project that there was going to be a lot of guesswork in the planning, and that whomever we hired for the project would have to make changes on the fly. The planning team was very clear about what they knew, and what they were inferring based on their experience and what they might discover when they started excavating.

    They presented us with us a few different proposals with breakdowns of the cost and a list of the pros and cons of every plan, answering all of our questions before we finalized our choice.

    The whole team at Terra Firma was incredible throughout; clear, consistent communication about the progress on the project and how it evolved as the plans encountered reality. It was a job well done with consistent care and extra effort. Whether it was the on-site team or the office staff supporting the project, everyone was a genuine pleasure to work with.
    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.
    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!
    100% will recommend this company. Friendly, respectful, professional employees. Rare in these days and times.
    Quenton came to service crawl space sump. He did a thorough inspection of the whole space. Cleaned and serviced sump that was full of clay. Found issues and gave recommendations with pros and cons. He didn't push any unneccessary things. Took pictures of all issues and work and thoroughly explained everything. Installed a new dehumifier and removed old one and hauled away. Would recomnend this guy to anyone. I hope this guy is an example of how the business is run. Excellent job, very happy.
    Estimator Seth patiently answered all my questions allowing me to make an informed decision with no pressure. Foreman James was respectful as he let me know exactly what they were about to do and why. His team including Oscar and Brian were hard consistent workers. They lifted the back on my home 1 and 1/2 inches and all my doors shut for the first time in years. My home was now level, the cracks in the walls came together and the squeaking in the floor stopped. It was amazing. Highly recommended. No buyers regret. Thank you all at TerraFirma. Nick
    Seth. Was great. Very. Professiinal. Thank you Terrafirma Vince
    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.
    My wife and I have an old house that needs work done in the foundation. So I called Terra Firma, and they sent Seth to look things over and help us come up with a plan. We enjoyed his visit and were very comfortable having him in our house. He gave us some great options, and he followed through on his word with a prompt quote and follow-up call. Although the time isn’t right for us, we definitely feel that we can trust them to do good work. Thank you Terra Firma!
    Fastest turnaround time and most thorough bid I have ever seen! Sam goes way beyond the normal review and discusses the options with clients in a way that is clear and concise. Confident that the work will be beyond expected as well.

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