From Roseburg to Eugene, Portland to Seattle, our Foundation Repair work speaks for itself

Thanks to Jorge, Juan and Scott for job well done!
Seth C. was really helpful this morning. It has been raining so much lately and he was able to walk me through all the issues my daylight basement and garage can have and how TerraFirma fixes them. Really appreciate you--/thanks so much Seth
Jason came out and worked on my sump underneath my house. He did a great job and everything was OK. Thank you Jason.
Everything was done well and efficiently, The team communicated well with me, and cleaned up after themselves. It was expensive, but I feel confident that the job was done well.
They make it all easy. Not just good work, they have great process. I do recommend this group of people highly.
excellent customer services, excellent communication and services, the Best in the northwest
Fourth project completed by Terrafirma for our property and while not everything always goes according to plan, they make good and stand behind quality customer service. Today we had three amazing employees- Jorge, Juan, Alencio solve some tricky problems with a smile and positive attitude! So appreciate another solution!
The whole process was seamless - from our initial proposal where Hannah answered all of our questions and did a thorough assessment of what was needed to Antonio, Kameron and Jesse who did a great job on our encapsulation project. They showed up on time, were professional, very informative, cleaned up when completed, and were a pleasure to work with. Would recommend their services!
The process of stabilizing my foundation was done quickly and professionally. Permits and reports were provided upon completion. They were a pleasure to work with. The site visits were scheduled in advance and they were always there when scheduled. The final work was completed when scheduled and the site was cleaned up with minimal disturbance. If I had a question, they were always quick to explain the process. A pleasure to work with.
Five Star to the Aris's team who worked on site! My project was stuck and the boys drive all the way from Vancouver up to Seattle to rescue. When I met them for the first time, I was deeply worried because those boys look so young! However, I was quickly impressed because the young boys really rock! They are super friendly and polite, they are energized and work so hard, I can tell they are proud of their craftsmanship and really care about your property. Kudos to Brad, Aris, Jose and Rudy! For the overall experience, there was a huge gap between sales team and production team, be prepared that you may not get any material/product like what the sales person showed to you, I did a lot of research on their product and that was the main reason I selected them, however, I did not get any of the product with specification that were promised, so this is quite disappointing - but I understand this is not really sales or field technician's fault...
***Please note -- I updated my review from 1 to 5 stars. Terra Firma took the initiative to reach out and assess any next steps needed to correct the problem. Trust is 100% restored knowing that if problems come up they will take any action needed to follow up. I will also say that the work they originally did was actually to code, and we agreed that the moisture problems arose due to the nonstandard setup of my dehumidifier, NOT because of errors in Terra Firma's work. Thank you Terra Firma.*** Unfortunately, I have to drop a negative review in the interest of warning other folks that their work has gone downhill. I previously had an excellent experience with Terra Firma for management of a water problem in my crawlspace. I hired them without question again for my current property for management of moisture issues, and I didn't check their work upon completion as thoroughly as I should have. Unfortunately, about 1 - 2 months after completion of work, I discovered a large mushroom growing out of one of the structural posts in my crawl/basement. On closer inspection, I noticed that the dehumidifier water discharge line they installed was dumping less than a foot away from my foundation, corresponding to the exact spot the mushroom was growing. Moisture was the exact problem they were supposed to fix, but now they have created a severe structural problem secondary to moisture with the dehumidifier line dumping large quantities of water right next to my foundation. In other words, they created the exact issue they were purporting to fix by collecting the moisture and depositing it into my foundation. Once fruiting bodies are growing out of wood, this is an indicator that the wood is severely compromised and the fungus network has grown extensively. I now have a very expensive and serious problem to fix. I called to let them know about the problem, not sure if I will hear back from the coordinator/ the team who did the work. I am not sure if I would trust them to fix the issue after the damage they have caused, but I would accept financial remediation. If they take steps to make things right, I would update my review. I would not hire Terra Firma again for any crawlspace work, be it structural or moisture related because of the big problem they have caused. Again, just would like to warn others.
Last year our house flooded due to rising ground water in a daylight basement that we had assumed was sealed and waterproof. Well it wasn't! We hired Terra Firma to do a waterproofing job that included drain lines below ground, drain track around the inside corners, and a sump pump. Our install team (Andrew, Zach, Joey, and Kayden) were amazing. They arrived on time every morning, worked hard all through the day, and were done ahead of schedule. They answered all of our questions and even helped us plan the best way to resurface our finished basement floor so any future water damage would not create long term damage. We could not be happier with Terra Firma and our amazing install crew. Five stars for sure.
Excellent work - perfectly even walk now!
TerraFirma Foundation Systems is excellent at basement waterproofing. Be sure to ask about all the available options so you can choose the one that’s right for you. The company is very capable, but it’s important to do your research before making a decision. The crew—Antonio, Jessi, and Casey—worked extremely well together. Antonio is especially sharp; whenever I suggested an idea, he immediately understood what I meant and offered an even better solution on the spot.
Terra Firma is a wonderful company to work with. The scheduling and prompt arrival of the team to my house was exemplary. They were careful and knowledgeable and thorough with all of their work.
Andrew, Zach, and Brent arrived and completed the job on time. They worked with our old house’s existing flooring.
Fantastic job leveling out settled patio concrete slabs. Very efficient work done in about 4 hours. One area had a 2” trip hazard between slabs, now nothing! 5 year guarantee but should last 80 years
We had a complete encapsulation of our crawl space and sump pump and humidifier system installed. The young men who did the work were very professional. Antonio was the project manager and he was fantastic. Answered questions, explained the process, and made sure we were ok with what they were doing. They showed up at the time designated and called if they would be late. Communication was very good. Shout out to his helpers, Daniel, Jesse, and Kameron. At the end of the project they cleaned up the workspace and made sure things were left like it was before project. Thanks guys.
Very pleased with job done. The young man that did the work deserves all the credit. Prompt & professional.
From bid to project completion, this team has been fantastic. Derek took the time during th ebid process to explain what I needed and why I needed it. He treated me like a compentent human and gave me the info necessary to make a good decision. The crew of guys who did the work were fantastic. It's never easy to have people in your home, but Aris, Fernando, and Tyler were hard-working, gracious, and willing to keep me informed about each stage of the process. This was a significant improvement over our former crawlspace techs and we couldn't be happier. Thanks, guys!
Fast response. Courteous, professional employees in all areas of the company. Clear explanations of what needs to be done to fix the problem.
The crew showed up right as scheduled. The foundation work itself was completed in two days. Inspection and clean up occurred on the morning of the third day. I highly recommend Terra Firma.
My home is situated on a hillside that slopes south to north and east to west. My foundation stem walls along with my concrete floor were sinking and my floor was out of level. Terra Firma came and sunk several tubes down fifty-seven feet to stabalize my stem wall footings and they injected foam in several areas of my concrete floor to make it level again. They did a fantastic job and they were thourough and left my home in the same condition before they began the work. The only complaint I have is that the estimator indicated that many of the cracks in the concrete floor would close up with the foam and they did not.
We had Jason back this year for another service. He is the best guy super informative can’t wait to have him back next year. We have had our pump system for a little over a year now, the winter before we had up to over 1 ft of water under our house, this last winter nothing it was bone dry. I can’t say enough good about your company. We just had Jason out to do the first service on it and what a guy, he showed me how to check a couple things on the up coming season. We will definitely have Jason back next year to do our service again that guy is an asset to your company! Thank you Satisfied Customer
So we had Jorge, Juan, and Brad do an encapsulation of our basement crawl space and they did an amazing job. The area they had to literally crawl around in to complete the work was incredibly tight yet they completed their work without complaint and with style. It looks great! The work these guys had to do was tough, give these men a raise! They earned it!
Overall, they did a great job. Very easy to work with very professional. The guys who came to my house were great. They were very friendly and very kind. The foreman was exceptional. The individuals I talked to on the phone were very professional, very nice. They worked with me and got things done when I could get them done. I would recommend them to anybody.
The crew were on time, introduced themselves and made sure that we were all on the same page as far as what they were doing. Lifted the back patio up and leveled the sidewalk to martch. Looks great! Did a good job of cleaning up. I would reccomend them for any type of concrete lifting. Thanks guys!
I purchased two waterproofing systems from them a few years back. After the rain the past couple days its time to leave a glowing review. They did an interior drain in my basement and a separate drain tile system in my crawlspace. Both systems have been working flawlessly for 3 or 4 years now with zero water intrusion into my basement that I totally renovated after their install. They've also come out every year as promised for servicing. Thankful for connecting with them. After hearing the river of water enter into the pump and it go off every minute or so for nearly 12 hours yesterday, they deserve 5 stars. I would recommend them to anyone.
Great experience from start to finish. Communication was clear, service was prompt, and the work was done right the first time. Everything was explained in a way that made sense, and the space was left clean and tidy afterward. You can tell they take pride in their work and care about their customers. I would absolutely recommend them and would use them again without hesitation.
We worked with TerraFirma on a complex project involving installation of their EverBrace wall stabilization system. The project took a lot of planning and communication leading up to installation, plus a 3-week on-site job. Everyone I interacted with at TerraFirma was warm, communicative, respectful, helpful, and creative in solving any issues that arose. I could not have asked for a better customer service experience. Our project was expensive, and a stressful endeavor for a homeowner, but I felt I was in good hands from start to finish with TerraFirma. Not to mention that the EverBrace solution saved us tens of thousands of dollars. I highly recommend this company.
If you hire this company to put sump pumps in your basement, make sure you know exactly where they are going to put them and where the pipes that will pump the water outside will be coming out of your house. Even though one guy gives you a diagram ahead of time, that doesn’t mean the guy actually doing the work follows it. One sump pump was put in our basement just as we expected. The second one was not. We provided new electrical outlets dedicated for use to the sump pumps. The second pump now has cords hanging in mid air barely reaching the new plugs because that pump was not put where they told us it would be. Also, the pipes that take the water away from the house, we expected those to go through the foundation, not through the expensive cedar siding and be exposed on the front of our house! I was horrified to see those holes and said so. My husband redirected them to drill through the foundation so the pipes could not be seen once the work was done. They did that, but now we are left with holes to repair. They did not offer to repair them. The young men who did the work were kind and respectful and did what they thought were expected of them, but if you hire this company, make sure you know exactly where they are going to put everything and not assume anything even if you have a diagram!
Bailey did a fantastic job inspecting my crawl space and designing a solution that fit my needs. I really appreciated his thorough evaluation, detailed explanations, and professionalism. I will keep TerraFirma in mind for future projects.
We had a really great experience with TerraFirma Foundation Systems from start to finish. Danny was our first point of contact and handled our bid, and he set the tone right away - knowledgeable, straightforward, and easy to talk to. From there, everything stayed consistent. Jorge Valencia led the crew with professionalism and clear communication along with Juan B. and Alencio who all did excellent work on site. You could tell this was a team that knew what they were doing and took pride in it. It was incredibly muddy under our house, and not an easy job by any stretch, but the crew didn’t complain once. They just got in there and got it done. What really impressed me was that when they finished, there wasn’t a single speck of mud left behind. That level of care and respect for someone’s home says a lot. The work itself was done efficiently and with attention to detail, and they kept us informed throughout the process. No surprises, no confusion, just solid, reliable work. What stood out the most, though, was something more personal. I have a young son with Down syndrome who is very curious. I was honestly worried he might be in the way, but the crew handled it in such a thoughtful, human way. They took the time to acknowledge him, talk with him, and make him feel included. It was incredibly heartwarming. He felt seen and heard, and that meant a lot to us. It’s rare to find a company that delivers both high-quality work and genuine kindness, but this team did both. I would absolutely recommend TerraFirma.
Travis and the crew did an excellent job with our crawlspace project. They were always on time even though they were coming from Roseburg to Bend, and great with giving updates as they went. We love our new crawlspace now and grateful for cleaner air, better temperature regulation in the home as well as the added benefit of extra storage. Thanks TerraFirma!
Jayden inspected my house and gave a thorough report of the findings. I’m very happy with the service, and would call again if needed.
Noah with TerraFirma is very knowledgeable and walked us through all options. Answered our questions and I greatly appreciate all the visuals for options presented. I would recommend Noah to work with!
My mother-in-law’s house was built in 1962 and has had basement water issues for more than 40 years. We’ve spent so much money trying to fix it over the years, but TerraFirma Foundation Systems completely transformed the situation—it feels like magic. Thank you to the team: Casey from sales and the crew members Antonio, Jessi, and Casey. The three musketeers worked efficiently and truly operated as a team. Thank you for bringing such an incredible change to my mother-in-law’s home! One suggestion for management: please focus on bringing happiness to your customers rather than worrying too much about potential lawsuits.
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. 🙂
Bailey came out and did a thorough walk through, listened to my project plans, was very helpful and polite!
Sam was able to provide an excellent inspection and honest report of my crawlspace waterproofing needs. Didn’t feel rushed or pressured. Was able to educate me to better understand the issues and risks. Thank you so much Sam
