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

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 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
This company was very professional, clean, and careful doing our earthquake retrofit in our crawlspace. They even worked out a schedule with another company that took down and then replaced the air ducts that were in the way, minimizing the time we were without heat. I suppose the real test will be after an earthquake... but from what we can tell, I would recommend them for your project.
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!
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.
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.
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!
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!
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.
I hired TerraFirma to do a seismic retrofit on my house. The entire experience was outstanding! They showed up exactly when they said they would. The job was completed in the expected time and they cleaned up after themselves. I feel like the cost of the project was more than reasonable for the peace of mind l now have, knowing l have done what l can to protect my home in the event of an earthquake. I would recommend them to anyone who is looking for a professional company to work on their foundation.
When we first bought our 1900s fixer upper, we had no idea what lurked behind the walls of the illegal basement apartment. Once we opened up the space we were in for quite the surprise. All the wooden post holding up the main beam of the house were rotted through at the base. You could stick a pencil through the old, soft wood. Working with TerraFirma to fix the issue was an easy choice. Eric came out to assess our problem. He was friendly and professional as he walked me through the process that was needed to fix our foundation. It wasn't going to be cheap. Don't expect this kind of work to be inexpensive (especially on older homes). We needed concrete to be cut, 2ft cubic footers poured, and six shiny new steel posts. (And while they were coming out anyway, we had them do seismic retrofitting too). There's all kinds of math and engineering that goes into determining what's needed to structurally support a home. TerraFirma handles it all. And they are experienced enough to know what it's going to cost. One of the best parts of working with them (besides the friendly employees and professional workers) is that the price they quote you is going to be the price. Full stop. There are no unexpected add ons at the end. I can sleep well at night knowing TerraFirma's work is holding up our home. A few months later when the rains started in earnest and our basement flooded (an issue we guessed had been going on for a while, hidden by those illegal apartment walls and leading to the rotting of the old wood posts) we knew who to call. Eric came out again to look at options for a sump pump system and even worked on adjusting those plans (while he was on winter vacation with his family!!) when we discovered that a third wall was seeping water and we needed a much larger amount of fixing than originally thought. We no longer have to worry during downpours. While our old fixer upper still needs a lot of work and love, we know that we are (literally) starting from a strong, solid foundation thanks to TerraFirma.
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!
