HOMES RETROFITTED & HOMEOWNERS PROTECTED

Don’t take our word for it – see what our clients have to say.
From Roseburg to Eugene, Portland to Seattle, our earthquake retrofitting work speaks for itself

TerraFirma did a great job with the earthquake update on our home. They were friendly and performed the work in the time expected and at the agreed cost.
I have used TF for several projects, their teams are very good to work with. Jacks were installed on a sinking garage wall, foam leveling of garage and patio slabs, seismic upgrade, and additional footing piers. It was large undertaking. When we redid our driveway, we discovered roof drain issues the required additional foam for the void under the garage. They are very pleasant to work with.
This company is the gold standard for those interested in maintaining the health of their home. I tell you, ‘My home will never be the same’: The garage is level; We are earthquake proof; And, the will no longer be mold or mildew in my crawl space. The best part was, not just the satisfying outcome of the work done, but meeting & working with Walter. He talked to me so that I understood why parts of my home were on a downhill slope to disrepair. He drew illustrations so I could visualize each point he made: He was upfront & honest in his assessment of my 1972 home built in clay. If Terra Firma is the gold standard- Walter sure is the diamond. Get your free evaluation today & don’t forget to ask for Walt.
I called TerraFirma to inspect my foundation with idea I may have them retro fit it with bracing for earthquakes. Not an easy inspection either, tight crawl space in 105 year old house. While the company rep could have told me they would be happy to do it, he was very honest and told me that because my foundation was so old and not in the best of shape it probably wouldn't do any good if an earthquake were to happen. As the bracing would more than likely just pull out of the foundation. I was very impressed with the honesty of the company to tell me this rather than just shine me on and take my money for a job that wouldn't really do any good. So I can highly recommend this company for an honest review of your property. Rich Wolles. Eugene Oregon
I did a ton of research on TerraFirma when I decided to pursue getting a seismic retrofit in my basement, and then to clinch it, my Engineer neighbor spoke highly of them as well, stating they are top tier in their field. Jake's Crew came out today to review, and instead of selling me on a $10,000+ price tag, educated me on why they were unable to do the retrofit - my foundation is hollow concrete, their drilling would shatter it, and their alternative wouldn't meet my required needs. Honestly, I'm BLOWN AWAY how awesome Jake's Crew was - honest, direct, helpful, and educated me on my foundation. They even cleaned up under the porch for me, graciously turned my outside water off under the crawl space (thank you!!!). I'm so sad my foundation isn't able to be seismically retrofitted but I'm ridiculously grateful to Jake's crew for being so honest. I highly recommend TerraFirma - I read a ton of reviews on multiple platforms, and when they do make a mistake they fix it and make it right. They are full of integrity, and I'll forever remain impressed and won't stop recommending them to anyone/everyone!
Seth visited our home to give us a quote on seismic retrofitting. He was on time (and made sure to call when he was heading our way), did a thorough assessment of our home, and was an absolute pleasure to work with. During the assessment, Seth patiently answered all of my questions. It was clear that he was extremely knowledgeable about the available retrofitting options and what best suited our home. The final proposal was easy to understand; it clearly outlined the work to be done, why it needed to be done, and how much various options would cost. Overall, it was an excellent experience.
I can't praise Terra Firma enough for their superb service throughout the process of having an earthquake retrofit done on my house!! Design specialist James Kershaw did a thorough assessment and explanation of the recommended work. Scheduler Jonah promptly contacted me with the work dates and coordinated with the plumber for related work. My OUTSTANDING team of workers with Jonathan (foreman), Nathan, Rom, Matt and Daniel worked tirelessly and efficiently and with cheerful and respectful attitudes. They exercised great care in protecting my home and in cleaning up at the end of the job. I HIGHLY RECOMMEND this company for their superb, specialized services!!
Seth came out today to check under my house to give an assessment on ways I can improve my foundation for earthquake protection. He was awesome. He was on time and very personable. He explained things (with pictures) very clearly and answered all my questions. I was very impressed. 🙂
No clue if the job ws done technically perfect or not. Hopefully, I will never know (no earthquacks). they kept me well informed, were prompt, polite and left no mess.
Excellent from start to finish. I am very impressed! The team who did the earthquake proofing were hard working, friendly, and professional. They did a great job of cleaning up after completing the project.
TerraFirma installed EverBrace on our hundred year old foundation. It was a cost-effective way to proactively prevent foundation failure while also adding waterproofing and earthquake resilience. TerraFirma was a joy to work with, especially considering the size and complexity of the job. Our sales person and project manager made it feel easy from the very beginning. The installation crew was particularly great, always arriving exactly on time, explaining what they were doing each day, and answering any questions. They went above and beyond to not only complete the project as planned (and right on schedule) but also took care to leave the site in better condition than they found it. It's clear that Rocky and Harley take pride in their work. Earthquakes now don't seem as scary, and we love our new clean and dry basement!
Everyone, from the job estimator and office staff to that guys that repaired my foundation/driveway and installed the earthquake mitigation system, were very professional and courteous. Very happy with the final result!
