Service Area

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!

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!

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.

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.

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!

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!

The crew were on time, introduced themselves and made sure that we were all on the same page as far as what they were doing. Lifted the back patio up and leveled the sidewalk to martch. Looks great! Did a good job of cleaning up. I would reccomend them for any type of concrete lifting. Thanks guys!

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.

Brian was great, super friendly and professional. He gave us a very thorough bid after completing an extensive inspection.

They scheduled for a week but were done in 3 & half days. Worked around my gigantic existing sump pump cleaned out debris from the plumbers and sealed off my crawls space. Travis & is team were fantastic! Highly recommend the company & Travis's team to everyone.

Noah was extremely thorough and explained his findings clearly with optional choices of services that we needed with the pricing. He was friendly, courteous and easy to talk to. We would highly recommend Terra Firma. Noah is a very valuable representative of the company.

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

Andrew, Zach, and Brent arrived and completed the job on time. They worked with our old house’s existing flooring.

Antonio, Jesse and Kamron were fantastic today! They explained everything they were going to do and then made sure I knew next steps. I highly recommend working with Terra Firma.

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 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.

Inspector Elijah was on time when he said he was going to be there was very prompt and personable. I feel like did a very thorough inspection of my crawlspace.

Jason came out and worked on my sump underneath my house. He did a great job and everything was OK. Thank you Jason.

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.

The crew showed up right as scheduled. The foundation work itself was completed in two days. Inspection and clean up occurred on the morning of the third day. I highly recommend Terra Firma.

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

My home is situated on a hillside that slopes south to north and east to west. My foundation stem walls along with my concrete floor were sinking and my floor was out of level. Terra Firma came and sunk several tubes down fifty-seven feet to stabalize my stem wall footings and they injected foam in several areas of my concrete floor to make it level again. They did a fantastic job and they were thourough and left my home in the same condition before they began the work. The only complaint I have is that the estimator indicated that many of the cracks in the concrete floor would close up with the foam and they did not.

Everything was done well and efficiently, The team communicated well with me, and cleaned up after themselves. It was expensive, but I feel confident that the job was done well.

Pat was so good not only at his job, but is an extremely personable type of communicator, is polite and most of all knowledgeable. I’d say he is going places with this company! It is hard to find adequate people these days, let alone someone who is capable of carrying on an educated and informed conversation while listening to my questions and concerns , then actually (past 5 pm on over-time) taking the time to explain them. He was patient and kind to both me and my young daughter. I appreciated his honesty about working with connected buildings, even if it risked new business for his company. If he isn’t already a manager, he soon will be! If you call Terra Firma i’d suggest asking for Par and if Pat works for you, I’d suggest a raise next review!! lol

We had the pleasure of working with Samuel Bryant, System Design Specialist at TERRAFIRMA, who provided us with a complimentary foundation and crawlspace inspection along with detailed repair estimates. Samuel was highly professional, knowledgeable, and responsive throughout the entire process. He delivered a comprehensive inspection report and repair design that clearly outlined the property’s condition and potential issues. His thorough assessment gave us valuable insight during our home-buying decision and helped us better understand the risks and costs involved. We greatly appreciated the time, expertise, and attention to detail that Samuel and TERRAFIRMA provided. Their excellent service and professionalism left a strong impression on us, and we will not hesitate to reach out to them again for future foundation or crawlspace needs. Highly recommended!

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

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

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

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”.

***Please note -- I updated my review from 1 to 5 stars. Terra Firma took the initiative to reach out and assess any next steps needed to correct the problem. Trust is 100% restored knowing that if problems come up they will take any action needed to follow up. I will also say that the work they originally did was actually to code, and we agreed that the moisture problems arose due to the nonstandard setup of my dehumidifier, NOT because of errors in Terra Firma's work. Thank you Terra Firma.*** Unfortunately, I have to drop a negative review in the interest of warning other folks that their work has gone downhill. I previously had an excellent experience with Terra Firma for management of a water problem in my crawlspace. I hired them without question again for my current property for management of moisture issues, and I didn't check their work upon completion as thoroughly as I should have. Unfortunately, about 1 - 2 months after completion of work, I discovered a large mushroom growing out of one of the structural posts in my crawl/basement. On closer inspection, I noticed that the dehumidifier water discharge line they installed was dumping less than a foot away from my foundation, corresponding to the exact spot the mushroom was growing. Moisture was the exact problem they were supposed to fix, but now they have created a severe structural problem secondary to moisture with the dehumidifier line dumping large quantities of water right next to my foundation. In other words, they created the exact issue they were purporting to fix by collecting the moisture and depositing it into my foundation. Once fruiting bodies are growing out of wood, this is an indicator that the wood is severely compromised and the fungus network has grown extensively. I now have a very expensive and serious problem to fix. I called to let them know about the problem, not sure if I will hear back from the coordinator/ the team who did the work. I am not sure if I would trust them to fix the issue after the damage they have caused, but I would accept financial remediation. If they take steps to make things right, I would update my review. I would not hire Terra Firma again for any crawlspace work, be it structural or moisture related because of the big problem they have caused. Again, just would like to warn others.

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

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.

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

We worked with TerraFirma on a complex project involving installation of their EverBrace wall stabilization system. The project took a lot of planning and communication leading up to installation, plus a 3-week on-site job. Everyone I interacted with at TerraFirma was warm, communicative, respectful, helpful, and creative in solving any issues that arose. I could not have asked for a better customer service experience. Our project was expensive, and a stressful endeavor for a homeowner, but I felt I was in good hands from start to finish with TerraFirma. Not to mention that the EverBrace solution saved us tens of thousands of dollars. I highly recommend this company.

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.

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.

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.

We had an excellent installation on a fantastic crawl space waterproofing job. We are on the northern Oregon coast and a few feet from the sand so we get a lot of moisture under our 1940s home. We decided to invest in the TerraFirma product after a great meeting last summer with Don as we were taking on a major house renovation and decided we would do what is best all at once. We are very happy we did as the product is a game changer for the health of our home and our next generation. We pick up some great additional waterproofed storage space too in the end. The install process was efficient, and we had three outstanding guys working our job. Antonio, Jesse and Cameron deserve a big shout out. They spent time each day we dropped by to educate us on what they did that day, show us every aspect of the job and took great care to be hospital-like clean. Sometimes not-so -ice people do very good work, and sometimes really nice people do shabby work but in our case with TerraFirma, we received an excellent service from very nice guys. So glad we found Terra Firma!

Professional, considerate and competent. The crew all the way to the office was a pleasure to work with. A major project was done. They made it look easy! Thanks again Conner Brad and James.

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.
