Service Area

We were in the process of selling our house when the buyer's inspector thought our entire front porch concrete area and a supporting post needed to be replaced due to some minor settling of the concrete. I asked TerraFirma if they would send someone to come and inspect the area and get their opinion. Within a few days of my request, Walt Bateman, a System Design Specialist, came and did an inspection. After spending a lot of time measuring and inspecting the front porch area, Walt spend considerable time explaining to me that the buyer's inspector's recommendation was not warranted and he offered a reasonable and easier solution. I was very impressed with Walt's knowledge and his very simple and reasonable explanation of what he found. Walt was very easy to talk to and extremely personable. My experience with Walt and TerraFirma was extremely positive and I would highly recommend them for the services that they offer.

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.

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

The foreman was very detailed oriented, gave good consideration to the job, and was very easy to work with. The work done was excellent and the crew left the work site in better condition than what they started with.

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.

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!

Robert and Jacob came out on a cold, breezy December day and injected the company's foam-brew under our one-hundred-year-old staircase, raising it nearly 1 inch and thereby reconnecting it to our home! No small feat! As a realtor who has recommended TerraFirma to several of my clients, I've come to expect this kind of service, but I wanted to call out the guys for their professionalism and resolve when rain threatened. They also had great info (pics, measurements, etc.) from the estimator, making the project well-organized and timely. Well done!! Highly recommend.

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.

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.

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

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.

I was pleased with the work of the technician, Schylar. He arrived on time, explained the process, answered my questions, completed the work and conducted a final review with me. He was able to level out a slab floor on an outbuilding with excellent results. Schylar also did a thorough job cleaning up at the end. He also saved me a considerable sum of money by not performing work that was unnecessary. Thank you!

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.

Just had our annual inspection/maintenance check on our sump system, and the tech Steve-o did a great job. Unlike the tech the previous year, who barely even glanced at the system before charging $180 bucks for the service, Steve-o inspected every part of the system, removing and doing a full inspection/cleaning of each pump. He gave us thorough explanations of what he was doing and any issues he found, and gave us several options for continued maintenance going forward. Huge improvement over the previous year. Update (12/17/2025): During this morning's crazy wind storm we lost power at 2am, and unfortunately our battery backup sump pump was at the end of its life and the motor died. We scrambled to get our generator running in time to avoid disaster, but in the meantime we were without a battery backup with more storms on the way this week and holiday travel where we were planning to be away. I left an urgent message at probably 3am for TerraFirma, and got a call back from Lucinda at maybe 7:30. She managed to find a tech to come out this afternoon, who apparently came up from Roseburg to help with today's issues. The tech Jason was able to get a new backup, a new battery, and new controller box. Huge peace of mind for the coming weeks. No one loves an unexpected bill before the holidays, but I'm grateful to Lucinda for making it happen and Jason for getting the work done quickly for us. TerraFirma continues to do us solid. Thanks!

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.

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.

Great service from all involved; from the appraiser, the office and crew. Thanks especially to Dennis and Travis.

The guys were real efficient and professional. We’ve used Terra Firma for close to 10 years and it’s always a positive experience.

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

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!

Terra Firma is professional and operates with integrity

They make it all easy. Not just good work, they have great process. I do recommend this group of people highly.

Professional service, courteous install crew, clean install, problem solved so far.

Contracted for sidewalk and patio leveling and Crack repair. Schylar being the person in charge. Very professional and provided excellent results with final product.

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!

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!

Exceeded expectations in quality and time frame

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 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.

Extremely professional, and above and beyond in their work.

We had a concrete driveway that was sinking on one side, large chunks of the pavement were completely detached. TerraFirma was quick to schedule an estimate. The estimate was thorough and a fair price. They were flexible with scheduling for the job itself. They arrived at the scheduled time, did an awesome job of cleaning the cracks, leveling everything, and sealing the cracks. The material to seal the cracks needed to be avoided by our dog for half a day to be safe just to prevent her nails from digging into it while it finished curing, but otherwise we were able to immediately walk on the driveway. It looks fantastic. If you're looking to give your exterior a visual improvement as well as prevent erosion of your driveway/foundation, this is such a great solution. The warranty is great too. Well worth the price. We feel comfortable moving on to additional projects that the driveway impacts, knowing it is sturdy.

Bailey Mercer came out on time, which is the number one indicator of professionalism in my experience. He kept the conversation short and to the point. He did not try to upsell me on things didn’t need, and to that point, neither did the sales staff over the phone. Bailey did the measurements, with precision and finished at a reasonable time. I have confidence that when we decide to secure our foundation we will be using Bailey Mercer as our go-to expert when we call TerraFirma.

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!

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.

Terra Firma was such a professional business to work with. Their technician did a comprehensive diagnosis of our foundation and the team that came to fix our foundation did an incredible job! So thankful to know our foundation was fixed and passed all inspections.

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.

I am very pleased with the completed work raising the back door porch entry, they were on time, very polite and professional, had all the tools and equipment to do the job.

Sam was amazing. He provided 4 different options and let me know the price ranges to work with my budget.

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 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. 🙂
