Terra Firma has done a very nice job! The work was professionally completed. They were thorough and communicative. They walked me through all the details as they went and cleaned up well when they were completed. Very nice work!

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.

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.

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

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.

Brian came out and gave such an honest report. He was stellar to work with, and if we have any further problems,Terra Firma has my business.

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.

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.

We recently had two wall systems installed for two homes in our HOA. While there were some scheduling challenges along the way, Rocky was incredibly supportive and accommodating, ensuring the entire experience was handled with care and professionalism. He truly went above and beyond to make sure the work was completed with exceptional craftsmanship and attention to detail. I highly recommend TerraFirma, and especially want to recognize Rocky and his partner Harley for the outstanding job they did.

Excellent work - perfectly even walk now!

The Terra Firma team of Luis Juarez, Jose V., and Jorge D. were very dedicated and thorough in the crawl space encapsulation project at our home. They worked long hours to get the project done well and on time- as promised.

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.

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!

We had some basement flooding in our house and after learning the cause, we started the work of getting quotes and inspections from Foundation specialists. When we called TerraFirma, Bailey was able to make time for our inspection within the week. From the jump, Bailey was very communicative, and set expectations upfront. He asked what was going on, looked at some suspected intrusion points and then let me know he'd carry on with the inspection and would let me know when he was ready for me. No awkward standing around or wondering how long it would take. Bailey was very thorough with his inspection and had an impressive presentation once he'd made a diagnosis. He told me his ideas and then asked me mine and we both felt good about the plan walking away from it. Ultimately our timeline didn't work out and we personally had to go a different direction, but if it did I'm confident we'd be in good hands with Bailey and TerraFirma!

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.

Had TF raise the cement front porch of our house. The entire process, first contact, through the bid, through the job, through the billing, went smoothly. Their price was very competitive.

I am handicapped and use a wheelchair. Part of my sidewalk had sunk 3 1/2 inches. Schylur came in and had it completely level and sealed in just an hour or so. Couldn’t be happier.

We wanted the best and we got the best, we didn't even call around, we called terraFirma. We.live on the Oregon Coast, Beaver, Oregon. Casey came out and was here for two hours. He went under our 102 year old house and came out with pictures. He immediately had several options with prices, we were impressed already. We called him the next to say we wanted the biggest one. 21 smart jacks, a main beam replacement, total encapsulation with dehumidifier and sump pump. TerraFirma scheduled us for the next month which for us was extremely fast, we counted the days and as said, Aris, Brad and Jose were here right on time. To the owner of terraFirma, these young men should be commended for their professional, excellent work ethics. They were all very polite, very hard working young men. I would come out of the house and they would all wave and say good morning. Even in the afternoon they would wave to me. These three men spent 8 days under our house on their stomachs, sides and backs, hauling everything out in trash bags (about 50) and the then the rock that they hauled under for the trench, all while laying down because of the foot and a half clearance under their. I'll get where I'm going here, Casey, Aris, Jose and Brad were all excellent and I'm sure you're very proud as I am honored to have met and kinda know them. Thank you all, we are very impressed with our crawlspace. Jeff and Ana De Lanoy

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.

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.

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

excellent customer services, excellent communication and services, the Best in the northwest

Andrew and his crew were wonderful. They worked, without complaint during an intense rainstorm. They were polite, quick, and clean! I highly recommend them and their services! Thank you!

We had a great experience with TerraFirma. The crew that waterproofed our basement were Aris, Manuel, and Cristian, and they were super pro and cleaned up everyday after work. This crew was just great, they were friendly and worked hard every day. Give these guys a raise!

Walt listened to my concerns and did a thorough job of evaluating the foundation. When he finished, he took the time to explain what was normal settling, and what was concerning. He pointed out that I had a drainage problem around the foundation that needed attention, and might prevent the settling from becoming critical. I loved that he was not just out to sell me a service!!! I feel like I can trust his recommendations when I have him back to see if the new drainage solved the problem. Thanks Walt!!!

The crew were friendly and professional. The entire job only lasted two days and looks fabulous. The foreman kept us informed every step of the process We are very pleased with the results.

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!

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!

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.

Skylar was wonderful to work with. Was very professional and did a great job with raising our concrete pad.,

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.

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!

Great company. They have done several projects over the years. Always good work ethic! Hard work! Cleaned up, put things back, all good

Terra Firma was the most professional contractor I have ever dealt with. They kept me informed through text and email of where we were at in the process. They showed up on time, they performed the work flawlessly. They gave me a quote the same day, actually immediately after they looked over my job which I have never heard of. I was very impressed with TerraFirma and highly recommend them.

Thank you Andrew K for doing an excellent job smoothing out our sidewalk. There were extra challenges because of tree roots but Andrew thoughtfully came up with effective solutions and minimal grinding. He was on time, efficient, and very helpful. A job well done!

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.

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!

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!

Terra Firma is professional and operates with integrity

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.
