Service Area

Update: Robert and Jacob showed up and fixed my sagging kitchen floor. Punctual, professional, thorough, fast! Highly recommend TerraFirma to anyone needing foundation services. Overall total experience was top notch!! Thank you TF!! Noah arrived punctually and impressed from the get-go! He was here for an estimate visit and began with the explanation of how the appointment would be performed He was very thorough in explaining every detail and options available to me. Although I have not committed, Noah’s professionalism and knowledge were on point and I am definitely going to consider using Terra Firma for my sagging kitchen floor. Stay tuned…

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!

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.

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

Terra Firma is professional and operates with integrity

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.

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.

Good customer service, good quality work and timely.

We had concerns about the foundation and flooring of the home due to water and moisture in the crawl space. Walt, out of the Roseburg office was very responsive and timely with accurate information for our situation. Ultimately, we decided on crawl space encapsulation. The bid was easy to read and laid out a comprehensive work plan for our home. They were also able to meet our scheduling needs for the timeline of our project.

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!

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

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.

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

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...

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.

Wonderful people from start to finish. Morgan, who surveyed the job, Tammi in the office and the guys who did the work were ALL TOP SHELF!!!

Very impressed with the person who came and did a thorough inspection. He provided multiple options and estimates. I had a few jacks placed under the house after noticing structural changes in my home. The team that came to do the repairs worked so well together, didn’t make a mess and were very professional. I was happy with everyone I worked with.

Tyler came out and did a great job of thoroughly going through the house and taking measurements and pictures to document what need attention. He walked me through options and gave his recommendations. While I had other bids, he kept in contact and checked in to see if I needed anything else. He did a great job working with my unique situation, never pressuring me to go in any other direction then what I comfortable with. Then Victoria was great is getting everything set-up and connecting me to the crew that would be out to work on the project. They were there promptly the day as scheduled, which I appreciated. They did a great job of walking me through the process and explaining everything that needed to be done while I was working. They were fast and communicated clearly throughout the process and made sure I was there when they finished up. They cleaned up better then I expected considering they had to dig up a lot of soil and replaced the fence without it even looking like it was moved. I was able to get back the 1/2 an inch or so back from the chimney moving away from the house, so I was very happy about that! I would highly recommend them again and if I need the house foundatio repaired, would definitely call them back. Time will tell if everything stays where it is, but so far it's been a wonderful experience. They were competitively priced but seemed like they wanted my business more then the others and made me feel valued.

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

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

Excellent work on transforming crawl space. The experience with Terra Firma was outstanding from our first meeting with the technical specialist Andrew Fry through the completion of the project. The work crew was courteous and professional and did a fine job. Thank you Terra Firma!

We had Tyler from TerraFirma come out to bid fixing a standing water issue in our crawlspace. He was thorough (crawled the entire crawlspace), knowledgeable and responsive to questions. As a real estate agent having access to good contractors is vital, and his professionalism has placed TerraFirma solidly on our short list.

Had Walt come out to Corvallis to assess our concrete slab foundation and he was very knowledgeable of everything he observed surrounding the home's foundation. He took time to understand our concerns and provided us with his solution to our problem. We ended up having a structural engineer come out to asses our home and get his recommendation on if the work was needed. Although we ended up not needing to have the work done, the structural engineer said that Walt's estimate on the work needed to fix the problem was correct and if our house truly needed it, then he would have recommended the exact same work be done. In the future, if we have any other concrete/foundation projects around the property, we will definitely be calling Walt again.

The crew that did the work were great and did a GREAT JOB.

Skylar did a great job saving our concrete deck that was cracking. It feels much more stable. He explained the process and got it done. Left the area spotless

Crew was very professional. Arrived right on time. Cleaned up daily on job. Raised outer edge of our sunroom after installing 4 piers and new support posts.

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!

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

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.

Seth has made this process so streamlined and time efficient. I was concerned about my foundation issue, however he was able to assess the issue and present a viable solution with ease. He explained what had occurred and how to fix/ prevent such issues in the future in a way that left me informed and empowered to make informed decisions about going forward. He and his team has been prompt with communications and even sent photo updates of the work being complete, as I was out of town at the time. I really appreciated Seth going out of his way to make this the best experience possible, taking pride in his work and putting in the extra effort.

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!

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!

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!

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

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!

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!

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.

I met with Walt Bateman this week to discuss an issue I have that sounded like TerraFirma was a good place to look for a professional opinion. Walt shared his expertise and extensive knowledge of about 30 years of experience in the Eugene / Springfield area regarding geotechnical and residential construction issues and solutions to foundation and concrete structural issues in our wet environment. We discussed a variety of potential alternatives and he left me a relatively easy and cost effective solution for my project. I was very pleased to meet Walt and happy with his response just one day after contacting TerraFirma. I highly recommend Walt as an honest straight shooting guy and happy to get his opinion for my project. Thanks to Walt and TerraFirma, Steve Z, Springfield, OR.

I just want to share that they showed up on time, did the work they promised to do and they applied unforeseen discounts to the final bill that were unexpected. Shaving thousands off my bill at the very end. In a word “Trustworthy”.

The estimator, Tyler, and the applicator, Skyler, were very knowledgeable, efficient and friendly. Both explained what they were doing and how the process would help our deterioration under our garage floor. The process leveled out our garage floor. I believe it will also help stop the cracks that have increased in size over the years. I believe this process works!
