How do I know if my Olympia home needs earthquake retrofitting?

What does earthquake retrofitting usually include?

Earthquake retrofitting may include foundation bolting, cripple wall bracing, crawl space structural reinforcement, added connectors, and a detailed seismic foundation inspection. The exact solution depends on your home’s age, construction, and existing foundation condition.

How long does earthquake retrofitting take?

The timeline depends on the size of your home and the type of structural reinforcement needed. After the inspection, TerraFirma will explain the scope of work, expected timeline, and recommended steps before any work begins.

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

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!!
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.
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 worked in the real estate industry for 5+ years and would recommend TF to clients but never had the chance to use them personally until recently. They are simply the best around as measured by the people on their team, the proposal they made (I had 3 different contractors bid our basement work), the execution, the willingness to get it right, and the fact that in my instance I was able to complete Radon, Earthquake Retrofitting, and Basement Waterpoofing with the same outfit with great long term financing and a warranty in place. I highly recommend Terra Firma. Thanks guys!
I had two estimates. TerraFirma was much cheaper but more than that they moved fast, were clean, professional. The inspector gave them high marks and I have a house that is earthquake secure to magnitude 8 give ir take.
Terra Firma seismically reinforced my home to resist earthquake forces that could cause its wood frame to slide off its concrete foundation. Within about 5 hours, a Terra Firma crew of three bolted steel plates to the perimeter of my home, connected the perimeter stud walls to the concrete foundation walls. The installation was performed professionally, primarily on the exterior, with only only 6 of the 37 plates installed in an interior space where the of the foundation wall was several feet below grade, making exterior installation difficult, if not impossible. Terra Firma's plumber also installed a vibration activated gas supply shut off valve to my gas meter. I'm very pleased with the work and am hopeful that my home will remain habitable after an earthquake.
I needed to have 20 posts in my crawl space replaced and seismically upgraded. Bridget came out, was extremely helpful and knowledgeable and set up the project. Tony, harley, sebastian, came and did the work. They could not have been more friendly and professional. The work was done quickly and skillfully. Very excited to have this project completed and done so well!
It’s always been a joke in our house: “If you don’t want to be a responsible adult, you’re welcome to live in your mom’s basement.” It was funny because all I had was a dark creepy crawlspace with sharp rocks and whatever the last construction crew left behind. Unlit now. The Terra Firma team did exactly what they promised to do: in a matter of days, they terraformed the entire space under my house into an encapsulated sparkling-clean climate-controlled beauty. With the heat waves coming later this summer, I may be setting up guided tours for curious minds. The tour will include admiring a sump pump and earthquake braces, enjoying the cool clean air, and sliding like penguins on the white encapsulation layer. I haven’t decided on the fees yet, but it will definitely be a no-shoes, white socks-only service and I am NOT kidding about it. Thanks to Terra Firma, “living in yo-momma basement” turned from a threat into a perk.
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.
We purchased a home in 2020 that had undisclosed water infiltration in the basement that resulted in all basement finishes needing to be demolished to clean up the water and remove mold. TerrFirma was the only company who was able to diagnose and address both water infiltration caused by poor exterior yard grading and drainage and also the interior water proofing needed. They also repaired and stabilized a very large structural crack in our basement foundation wall. In addition to doing all this work they were also able to fit earthquake retrofitting into the project while here when asked (after they showed up to start the project). The estimator, Bridget was very meticulous in her bid and made comparing estimates easy. Her experitse, flexibility, follow through and communication were superb. Working with Spencer Hunt, the project foreman, was so stress free. He was able to accommodate our request for earthquake retrofitting even though TerraFirma was extremely busy. He was excellent at explaining everything the crew was doing. He checked in with us through every step of the process to make sure we were educated about and happy with the work. We are so happy we used TerraFirma and would recommend them to anyone who needs drainage, foundation, concrete, earthquake and waterproofing work done in the future!
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. 🙂
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.
