Don’t take our word for it – see what our clients have to say.
From Roseburg to Eugene, Portland to Seattle, our Foundation Repair work speaks for itself

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.
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.
I used Terrafirma for foundation support repair. I found the staff and work crew very honest and extremely thorough! Was a little outside my budget, but I was so happy that I chose them! Satisfaction in every area is so worth it!!
Will choose them over and over and refer!

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.
Exceeded expectations in quality and time frame
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!
TerraFirma has been wonderful to work with. Quinten was our tech today for our yearly maintenance. He was on time, even a bit early. Very personable and professional. He even took a minute to play ball for our dog. He found a problem with our wood support posts, gave us several options to address the issue.
Thank you TF and Quinten.
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.
We were able to get an appointment two days after calling and they were even able to come earlier after checking in to make sure we were available. Even though we were given some hard news about the repairs needed Jason did so in such a friendly and courteous manner. He was very patient with me and explained all of the proposal in detail. I really appreciate all of the time Jason took to help me today. It really made me feel like our house wasn’t just a job.
Walt listened to my concerns and did a thorough job of evaluating the foundation. When he finished, he took the time to explain what was normal settling, and what was concerning. He pointed out that I had a drainage problem around the foundation that needed attention, and might prevent the settling from becoming critical.
I loved that he was not just out to sell me a service!!! I feel like I can trust his recommendations when I have him back to see if the new drainage solved the problem.

Thanks Walt!!!
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.
Quenton came to service crawl space sump. He did a thorough inspection of the whole space. Cleaned and serviced sump that was full of clay. Found issues and gave recommendations with pros and cons. He didn't push any unneccessary things. Took pictures of all issues and work and thoroughly explained everything. Installed a new dehumifier and removed old one and hauled away. Would recomnend this guy to anyone. I hope this guy is an example of how the business is run. Excellent job, very happy.
Bailey came out and did a thorough walk through, listened to my project plans, was very helpful and polite!
Skyler's performance on our driveway project was exceptional. He provided a clear explanation of the planned work and accommodated our needs by working around the 5th wheel's relocation. The outcome exceeded our initial expectations. We are very pleased with the results.
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.
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.
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!
We worked with Seth Cunningham from Terra Firma in Tacoma and he was a consummate professional throughout the entire process.
We recently decided to sell the home and Seth offered to speak with the buyers about the work they did and the transferable warranty. This gave the buyers the confidence to move forward with the purchase. Many thanks Seth!
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.
Last year our house flooded due to rising ground water in a daylight basement that we had assumed was sealed and waterproof. Well it wasn't! We hired Terra Firma to do a waterproofing job that included drain lines below ground, drain track around the inside corners, and a sump pump. Our install team (Andrew, Zach, Joey, and Kayden) were amazing. They arrived on time every morning, worked hard all through the day, and were done ahead of schedule. They answered all of our questions and even helped us plan the best way to resurface our finished basement floor so any future water damage would not create long term damage. We could not be happier with Terra Firma and our amazing install crew. Five stars for sure.
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.
I purchased two waterproofing systems from them a few years back. After the rain the past couple days its time to leave a glowing review. They did an interior drain in my basement and a separate drain tile system in my crawlspace. Both systems have been working flawlessly for 3 or 4 years now with zero water intrusion into my basement that I totally renovated after their install. They've also come out every year as promised for servicing. Thankful for connecting with them. After hearing the river of water enter into the pump and it go off every minute or so for nearly 12 hours yesterday, they deserve 5 stars. I would recommend them to anyone.
Both crew's were on time. The crawlspace crew put down plastic from the front door to the crawlspace entrance in a bedroom. Work was completed on time, our closet doors reattached and the areas they worked in or went through left clean and tidy. The sidewalk crew completed their work in a day and even patched a crack we had forgotten to mention to the estimator. If TerraFirma also did crawlspace insulation, that would have been great, but I had to find another company for the insulation.
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 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.
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!
The crew that did the work were great and did a GREAT JOB.
Elijah did a fantastic job breaking down everything going on in my crawlspace and providing the estimates to get the repairs.
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.
A fantastic company,staff and did excellent job on my house.
We had Jason back this year for another service. He is the best guy super informative can’t wait to have him back next year.
We have had our pump system for a little over a year now, the winter before we had up to over 1 ft of water under our house, this last winter nothing it was bone dry.
I can’t say enough good about your company.
We just had Jason out to do the first service on it and what a guy, he showed me how to check a couple things on the up coming season.
We will definitely have Jason back next year to do our service again that guy is an asset to your company!
Thank you
Satisfied Customer
Brian was great, super friendly and professional. He gave us a very thorough bid after completing an extensive inspection.
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!
Friendly, professional and efficient. Very satisfactory experience. Would definitely recommend to everyone.
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.
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!
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!
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.
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.
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.
