Seth, awesome job on lifting my garage floor… it’s been a few months now and everything is looking great. Would recommend Seth on any job site, his professionalism and expertise can’t be ignored… Thanks James

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.

Quoted me $80k for proprietary solutions to some problems I do have, and some I don’t actually have. Took a bunch of pictures, showed them to me, but conveniently never sent them to me and thought it was weird I asked for the proposals to be emailed to me.

I decided to get a few other opinions and boy am I glad I did. Lying to me is one thing, but doubling down on the phone when you call me to ask if I’ve had time to consider scheduling the work is another.

I vote with my wallet and I have zero respect for a company that uses scare tactics or attempts to fudge the truth when they think the consumer isn’t educated enough on the subject to put two and two together.

Being a homeowner is hard and expensive enough… but then you have to navigate whether or not someone is trying to help you or empty your wallet for commission. This was arguably a worse experience than being a woman at the car dealership. No, I am not interested in purchasing blinker fluid…

Edit: With a continuous improvement mindset, I do appreciate someone at Terra Firma reaching out to me directly to understand the details of my experience so they could work to resolve internally.

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…

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!

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!

We were impressed with the crew that worked on our crawl space. They kept us informed about what was happening each day. They were respectful of our property and privacy. We would highly recommend TerraFirma.

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.

Seth C. was really helpful this morning. It has been raining so much lately and he was able to walk me through all the issues my daylight basement and garage can have and how TerraFirma fixes them. Really appreciate you--/thanks so much Seth

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!

Estimator, installer, and office communications staff were all great. Each person kept me well informed and up to date on progress. I have recommended Terra Firma to neighbors who may need help.

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!

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!

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

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.

Appeared on time and finished early. Everything done to satisfaction

So we had Jorge, Juan, and Brad do an encapsulation of our basement crawl space and they did an amazing job. The area they had to literally crawl around in to complete the work was incredibly tight yet they completed their work without complaint and with style. It looks great! The work these guys had to do was tough, give these men a raise! They earned it!

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!

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.

TerraFirma made a major error when fixing the foundation for the overhang of our Enumclaw Plateau Historical Society museum. The posts were not properly spaced, giving the front of the building an uneven appearance. When the error was pointed out to them, they admitted it, and apologized. They paid the repair costs without argument. According to a businessman on our board, this is an unusual occurrence. I want to give them kudos for their management acting with integrity.

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!

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!

This is our 2nd time to use Terra Firma and we can't recommend them highly enough. They had lifted our sunken front porch and driveway a few years ago. So when we were having bad odors and mice infestation in our crawl space we didn't hesitate to call Terra Firma. They sent the best design specialist Derek Ryan and the best crew ever to encapsulate it! Such hard-working, professional, respectful young men. Foreman Luis kept us informed and answered all questions. Actually all of them could knowledgeably answer our questions. It took them all week and Brad, Jorge and Jose. They worked their tails off!
We couldn't be more pleased.

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

Update: they sent someone back out to inspect the tree and work. Wouldn’t pay for someone to make the tree look nicer and mentioned they could give us a gift card or something for the trouble but never followed up with that. Ended up hiring an arborist on our own.

Estimator Derek was very friendly and helpful. Had a much better experience with him than I did with Groundworks. Quote was better too and took about a week to get on the calendar. Was able to get on the schedule fairly quick and they even called with a same day cancellation the Friday before we were scheduled.
Work that was done was okay, they were able to lift what we wanted on the main driveway and did their best in front of the steps. Unfortunately they used a jack, which I wasn't expecting, and ended up cracking the slab in front of the steps. It's in the contract that they're not responsible for this so nothing was done to mitigate it. Also a slab next to the large one lifted developed a large crack after they applied the stabilizing foam to the lifted slab.
Other issue is that they said it wouldn't be an issue to have the truck down our driveway as they have more than enough hose to work with. Unfortunately they backed the truck right into our magnolia tree and when they were pulling away it ripped a large chunk of branches out.

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.

Thanks to Jorge, Juan and Scott for job well done!

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.

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.

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.

The crew did a great job fixing our sinking foundation! Two days and they came in and dug everything up then set the anchors and then backfilled! Great Job!

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.

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.

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.

Terra Firma is a wonderful company to work with. The scheduling and prompt arrival of the team to my house was exemplary. They were careful and knowledgeable and thorough with all of their work.

I don’t usually do reviews but in this case people should know this is a first class company. Great communications and no selling you on something you don’t need. John was very professional, he spent time with us expanding what issues he did find, measured the level of the floors, inspected under the house and checked wall and foundation cracks. He also placed a blanket down to collect any dirt from entering and exiting the crawl space inside the house. I highly recommend John from the Eugene office and 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.

Absolutely fantastic

Terra Firma is an excellent company to work with. Everything from the assessment with Matt, the permitting process, and the actual job and clean up with Sam and his team went seamlessly. The foundation is now solid and feels much better. Exceptional service and quality workmanship. Highly recommended.

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!!!
