Service Area

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.

Job was on time, on budget, explained completely at each step and the crew (Jose H, Matt A, Ivan, Steven and Manuel) were meticulously clean through each day and cleaning up at the end of the week. Great experience overall, highly recommend. Phillipe oversaw the crew- he was tremendous! Thanks all!

Communication prior to work was great. Project manager explained how the work would go. The day the crew showed up the foreman went over the work plan and asked if I had any concerns, which I did and he was able to explain and accommodate without any problems. The crew put down plastic to minimize any mess or marks on my concrete and cleaned up post project work. I’m very satisfied with the work and complement the crew.

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

Noah was a pleasure to work with and demonstrated a high level of professionalism. He was patient in answering all of my questions and displayed extensive knowledge and expertise. He provided three separate proposals for foundation repairs.

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!

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!

Prompt, thorough, asked great questions…with great attitude and smile! TerraFirma has an awesome employee! Noah is a keeper! He deserves a raise! Keep up the great work!

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.

They did a very professional job.when there was a small problem a month later they returned and set it right at no additional charge. Punctual, Professional and Prompt.

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!

Bailey came out and did a thorough walk through, listened to my project plans, was very helpful and polite!

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!

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.

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.

2/16/26 update: My sump pump broke in December due to the high level of iron in the soil under my house. Terra Firma responded quickly and replaced the pump with no issue. Great customer service and a great team / experience! Thank you Terra Firma! Seth has been amazing to work with! I have been working with Seth on designing my crawlspace drainage system. Seth has been extremely helpful, patient, and professional. I've pestered him every day, multiple times a day with questions, asked for revisions to my quote, clarifications, and have been an all-around pest. Through it all, Seth has been responsive, communicative, and thorough. The work is scheduled for Mid-May 2024. I will update my review after the work is done with how it went with the crew and the job they did.

I had an excellent experience with Seth from TerraFirma during the field review of my home. He was punctual, professional, and extremely knowledgeable about every aspect of the house. Seth took the time to explain what he was seeing, answered all of my questions clearly, and made sure I fully understood the condition and next steps. It’s rare to find someone who combines expertise with genuine care and attention to detail, but Seth absolutely delivered. His professionalism and confidence gave me real peace of mind. I highly recommend Seth and TerraFirma to anyone needing a thorough and trustworthy home field review.

Very pleased with job done. The young man that did the work deserves all the credit. Prompt & professional.

Start to finish, great company to work with. Pat was thorough and polite when doing our estimate. Michelle was so nice in handling the scheduling. And, Brooks and Louis were incredibly hard workers who completed the work efficiently and just as expected. Excellent communication through the entire process.

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!

Absolutely fantastic

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.

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.

Excellent work - perfectly even walk now!

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.

Appeared on time and finished early. Everything done to satisfaction

Terra firma Oregon City Completed my basement waterproofing project. I want to give a shout out to Antonio , Kameron, Jesse For doing a very fast and efficient job Completing my waterproofing system.

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!

Arrived on time finished in one cleaned up everything

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

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!

We got an estimate on a leveling project from Noah last week. He was very competent, thorough, and knowledgeable. We enjoyed meeting and working with this personable young man.

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.

Very knowledgeable and professional

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!

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!

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.

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.

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.

Mr. Stanford did a thorough inspection of our crawlspace and gave us the honest opinion that very little needed to be addressed. He was very professional and clearly very experienced. This was after a competitor came out and tried to convince us we needed an $18,000 encapsulation.
