Testimonials

Terra Firma was really great to work with from our first meeting to the completion of the project. Hannah was our project designer, Kevin G. was our foreman, and Zach F. and Dorian assisted and all did a great job! Due to the cost of the project, we had to make a number of modifications along the way. And once they completed the demolition, they had to make another modification. However, their communication was great and they finished the project right on time and they did great, high quality work. I would definitely recommend Terra Firma for your basement issues.
I’ve always heard Terra Firma could repair sagging concrete on porches and they do. I couldn’t be happier with the results. Jonah our project manager was informative and although I might not like today’s prices it was less expensive than building a new deck. Ken and Dorian showed up on time, very professional, did a great job. After talking with Ken you could tell he had a lot of experience and it showed. I would Highly recommend using Terra Firma.
Everything was awesome. From the day they came promptly for the bid, they measured outside & under the house, answered our many questions to the day they came and did the job in less than one day - just as promised!Everything was awesome!
The crew showed up on time as stated in their bid. Did the work correctly and timely and then cleaned up before explaining what they did and installed. Much better experience than with the first contractor. More expensive, but you get what you pay for.
Fantastic work, great crew of people. They showed up on time, kept me informed of the progress throughout the job, went overboard to keep everything clean. I wish all companies were this professional about their work
Seth was knowledgeable, very experienced and the price was extremely reasonable. I had plenty of options to choose from. I also met with the competition and it felt like they were recruiting high schoolers to do their estimates.
TerraFirma is a fantastic company with great people! Seth was absolutely perfect! He did everything he could to help me! He answered all my questions and explained everything I asked in great detail. He was even able to get someone to come up all the way to Bremerton from the TerraFirma team in Oregon for my new radon mitigation system (the reason they don't usually do it here is because there is generally less need for radon systems here). Seth and TerraFirma are both a delight to work with!
I cannot express enough how grateful I am for the exceptional service provided by Seth and the team at TerraFirma Foundation Systems. We were facing a daunting challenge with standing water underneath our house, and Seth guided us through the entire process with professionalism, expertise, and genuine kindness.From the moment Seth arrived, it was evident that he was not only knowledgeable but also deeply passionate about resolving our issue. His expertise in dealing with water problems beneath homes was evident, and he took the time to thoroughly assess our situation (and got plenty dirty doing it) before presenting us with a comprehensive solution. He patiently answered all of our questions, alleviating any concerns we had along the way. It was clear that he genuinely cared about finding the best possible outcome for us.Consider this company, it'll be worth your time!
1. Foundation pier support - appears to be good work. 2. Earthquake retrofit - less than perfect on cutting into living spaces to attach hardware -...
Very professional, prompt, friendly and good work. TerraFirma was a great company to work with as they made every appointment, completed the job well, and explained everything.
