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. 🙂

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.

Professional, considerate and competent. The crew all the way to the office was a pleasure to work with. A major project was done. They made it look easy! Thanks again Conner Brad and James.

We hired TerraFirma to fix our foundation. They inspected thoroughly, explained the plan, and completed the repairs professionally. The process was smooth, and we’re thrilled with the results. Highly recommend TerraFirma!

Noah was on time, professional, knowledgeable, thorough, efficient, friendly, respectful, well-spoken, and thoroughly knew his products. He assembled a comprehensive, detailed, and extensive quote, estimate, and full project workup, complete with photographs from around, under, and through our home! Confidence in TerraFirma and their cabinet of staff is high. Would give six stars if I could.

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.

Very good experience from day 1. They ended up not needing one of the permits or a window brace like originally planned, of which both items were credited back to me. The installation crew was professional, efficient, and more than tolerant explaining all the little details of what they were doing while I watched the process. I really like that they live streamed their engineers the entire time for QC, and even had a third party review inspection. I chose TerraFirma over 3 other companies for the warranty terms and for them being a long established Oregon local business, and I am very happy with their work and crew. I hope to not have any future structural repairs done but if I do, I will 1000% hire them again. Thanks!

Giovanni and his crew were very professional. They showed up on time both days and got the job done on schedule. Giovanni carefully reviewed with us the work to be done before starting. At the completion on the job he reviewed what they had done. Giovanni was great to work with. He was very personable and had excellent communication skills.

***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.

I had a sump pump installed and these guys were fantastic from start of project to finish. Mychelle answered all my questions, Andrew and team were punctual, professional and got the job done fast, plus no mess. Thanks guys.

My sump pump service by Quinten was fantastic! He was very thorough, went above and beyond and took all my concerns seriously. Thank you so much!

Bailey was timely and thorough in his assessment, estimate, and reporting on my inquiry about a foundation crack. Although I decided not to have any work done at this time I was pleased with their service.

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!

Skyler's performance on our driveway project was exceptional. He provided a clear explanation of the planned work and accommodated our needs by working around the 5th wheel's relocation. The outcome exceeded our initial expectations. We are very pleased with the results.

I had Bailey come out to do an estimate for crawlspace encapsulation and some drainage work in the basement. Bailey spent 2 hours at the house and on the phone with me in total (not counting the work he did on his own), doing a very thorough work up of the house and patiently explaining what my options were, and what might be better for my renovation contractor to do. I really appreciated Bailey's willingness to think through different options - some that didn't include work for his company - and teach me about crawlspaces!

Zack, Andrew and Joey showed up every day by 8:30, worked their butts off & always left a clean work site... totally 5 stars for these guys. There was a 4th workerbee, but I never got his name & he was great too!

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!

Skylar did an outstanding job. Very knowledgeable. Very pleased with the results. Joe Henslee

Jorge and Juan came out to fix the discharge line. Both were very professional and sweet. Two of the best guys I have ever come across! Cherry on top was that my dogs really liked them, the guys did not mind that the dogs were being nosy, matter of fact they took the time to interact with them, not many people do. If ever anything needs to be fixed I highly recommend asking for them to do the job. Thank you so much for employing such kind and capable, respectful people.

This may not have been Terrafirma's biggest project but it was big to us. From the very beginning of diagnosis, estimates/proposals, the project management and communications, hand digging and cleanup, the entire crew made this stressful and expensive project very easy and seamless. Thank you Patrick, Brent, Mechelle and on site laborers(sorry I didn't get their names) for all of your amazing help.

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!

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.

Inspector Elijah was on time when he said he was going to be there was very prompt and personable. I feel like did a very thorough inspection of my crawlspace.

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!

Excellent team! Great attention to detail. Courteous, eager to please!

Seth came out to evaluate my foundation and gave me one of the most thorough and honest assessments I've experienced from a contractor. Professional, communicative, and zero pressure — he clearly takes pride in his work. I didn't move forward with the project through Terra Firma, but that has nothing to do with Seth or the quality of his visit. Highly recommend requesting him specifically. 5 stars.

Just a real pleasure to do business with. The System Design Specialist is very professional. And very thorough. Hailey Newman Is AAA+++ amazing! Everything explained in easy to understand terms. I really could not feel more confident about my issues and my options.

Thanks to Jorge, Juan and Scott for job well done!

I was referred to John from Terra Firma when I was looking to have our foundation inspected. John was very friendly and knowledgable and came out to our house to measure and inspect everything. In the end he was able to put our mind at ease and did a great job of explaining different scenarios and what he was looking for. John even inspected the crawlspace while he was out and provided great feedback there as well. Overall we got a lot of good information and never felt as though we were being pushed into unnecessary services. I will certainly be reaching out to Terra Firma for any future needs!

We worked with Seth Cunningham from Terra Firma in Tacoma and he was a consummate professional throughout the entire process. We recently decided to sell the home and Seth offered to speak with the buyers about the work they did and the transferable warranty. This gave the buyers the confidence to move forward with the purchase. Many thanks Seth!

Excellent experience with TerraFirma. Noah Bryant arrived on time, sent a helpful reminder, and spent nearly 3 hours thoroughly inspecting inside and outside. He took photos, clearly explained crawl space issues, and offered honest recommendations with options—no pressure. Very professional and sincere. Highly recommend!

Excellent work - perfectly even walk now!

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!

Quoted me $80k for proprietary solutions to some problems I do have, and some I don’t actually have. Took a bunch of pictures, showed them to me, but conveniently never sent them to me and thought it was weird I asked for the proposals to be emailed to me. I decided to get a few other opinions and boy am I glad I did. Lying to me is one thing, but doubling down on the phone when you call me to ask if I’ve had time to consider scheduling the work is another. I vote with my wallet and I have zero respect for a company that uses scare tactics or attempts to fudge the truth when they think the consumer isn’t educated enough on the subject to put two and two together. Being a homeowner is hard and expensive enough… but then you have to navigate whether or not someone is trying to help you or empty your wallet for commission. This was arguably a worse experience than being a woman at the car dealership. No, I am not interested in purchasing blinker fluid… Edit: With a continuous improvement mindset, I do appreciate someone at Terra Firma reaching out to me directly to understand the details of my experience so they could work to resolve internally.

Edit: Jan ‘26 Unfortunately this sump pump did not solve the problem after all, as water again came in after several days of hard rain. To be fair, TF did not guarantee a solution. I still think it is a good company but sadly my problem persists. Previous review from Nov 25 - Terra Firma installed a sump pump in my home that has solved my water incursion issues. This had been a problem for months. I had several different companies and professionals out to evaluate and try to solve the problem, from plumbers to leak detection companies and a few more. Most scratched their heads and said "this is a mystery." Terra Firma came up with this solution and it is working. I wanted to wait until we had significant rain to write this review - and after the past few days of pretty good rain, and no water coming in - I feel confident that the problem was solved. They were helpful, considerate and creative. They didn't try to sell me more than was needed. I recommend Terra Firma.

TerraFirma was there when they said they would be there. Their staff are always very professional, knowledgeable and enjoyable to talk to.

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

Good job it looks great and I would definitely recommend your company

Good customer service, good quality work and timely.

My wife and I recently bought a house and after removing carpet in the addition, we found fairly large cracks in the slab. Not sure of the severity we called terrafirma. They sent Dan out. Super cool dude and very informative. He was able to give us a solution to our problem. They were also able to fit us into their schedule quickly which was nice considering we had bare floors that needed to be finished. I would highly recommend terrafirma and co!
