Service Area

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.

Travis and his crew were absolutely outstanding. They were very friendly, clean and neat during the process. They informed us of a leak that we had no idea about. Saving us costly damage, we truly appreciate it. I had to go in the crawlspace since they completed the job. Absolutely amazing! Prior to them completing the job, whenever I had to go under, I was 50% sure something was going to jump out and kill me. Now, I feel I can easily camp out there with confidence. Thanks guys, Amazing!! Money well spent. Wish you all the best, for all your hard work.

The crew that stabilized the back corner of my house was experienced, professional, efficient and communicative. Luke, Tyson and Kyle kept me informed on their progress, discussed recommended changes to the original work order, reviewed the results of their work and left the site clean.

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.

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.

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!

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 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!

Arrived on time finished in one cleaned up everything

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!

Matthew was very professional my wife and I felt comfortable with his professional approach to our needs . I would recommend this company to those in need. Thanks

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.

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!!!

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

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

Jaden was prompt, professional and courteous. I would recommend him to anyone who requires his services.

Very knowledgeable and professional

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!

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.

We had a really great experience with TerraFirma Foundation Systems from start to finish. Danny was our first point of contact and handled our bid, and he set the tone right away - knowledgeable, straightforward, and easy to talk to. From there, everything stayed consistent. Jorge Valencia led the crew with professionalism and clear communication along with Juan B. and Alencio who all did excellent work on site. You could tell this was a team that knew what they were doing and took pride in it. It was incredibly muddy under our house, and not an easy job by any stretch, but the crew didn’t complain once. They just got in there and got it done. What really impressed me was that when they finished, there wasn’t a single speck of mud left behind. That level of care and respect for someone’s home says a lot. The work itself was done efficiently and with attention to detail, and they kept us informed throughout the process. No surprises, no confusion, just solid, reliable work. What stood out the most, though, was something more personal. I have a young son with Down syndrome who is very curious. I was honestly worried he might be in the way, but the crew handled it in such a thoughtful, human way. They took the time to acknowledge him, talk with him, and make him feel included. It was incredibly heartwarming. He felt seen and heard, and that meant a lot to us. It’s rare to find a company that delivers both high-quality work and genuine kindness, but this team did both. I would absolutely recommend TerraFirma.

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!

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.

After I bought a 115 year old house built partially into a hill near the top of Council Crest in Portland and discovered that the walls bled water when it rained, two walls were built into a hill and had endured the pressure of water and mud for a century, causing cracks and turning the foundation to crumbles, I called Terra Firma when an neighbor with an old house told me about her experience. Terra Firma has a great reputation. During the first meeting, Hannah walked the property and made a detailed proposal, explaining how Terra Firma would ensure that the walls do not cave in by shoring them up and anchoring them, supplemented with a vapor lock system to keep the water out of the house. NO MORE MUSTY SMELL, THANK YOU! Hannah explained the plan thoroughly, using her iPad to ensure that I understood. It could not get any better than this...I signed the paperwork immediately and contracted for the foundation repair and upgrade. This week, Geovany and his team spent four days working very hard and very smart to finish the project on time, and without any hitches. And they were working hard, very thoughgoing and steadfast. I am extraordinarily pleased with the work of the TerraFirma team, and how they did it. It is obvious by looking at the work that my basement walls are solid, secure, and dry. THANK YOU TerraFirma!

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.

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

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!

Antonio, Jesse and Kamron did a very thorough job on leveling my manufactured home. They were very professional in the process and now my doors and windows operate like they should. Gentlemen, I want to congratulate you on a job well done. Thank you, Cameron Gibson

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

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!

Exceeded expectations in quality and time frame

I was very happy with every step that Terra Firma took and all of the team members involved. I was able to get a very fast response and a quick booking for the work to be performed. I'd like to thank RJ for the thorough walk through and clear explanation of the issues and possible solutions. I'd also like to thank Antonio and his crew for the awesome job they did and the ability to get it all done in one day! I wouldn't hesitate to use them again and would recommend them to anybody needing the services they offer.

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.

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.

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!

Fast response. Courteous, professional employees in all areas of the company. Clear explanations of what needs to be done to fix the problem.

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!

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.

Absolutely fantastic

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

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.
