Service Area

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.

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.

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!

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

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!

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.

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…

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.

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.

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.

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.

***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.

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.

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.

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!

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.

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!!!

Bailey came out and did a thorough walk through, listened to my project plans, was very helpful and polite!

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.

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

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 were very happy with the work performed by the Terra Firma crew assigned to our crawlspace drainage problem. There was a project foreman assigned to the product (Luis,) and George and Christian were the other two workers. They were prompt, extremely hard-working, very clean and careful with the materials they used. We are very happy with the work of the Terra Firma crew and highly recommend them.

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

Terra Firma was the most professional contractor I have ever dealt with. They kept me informed through text and email of where we were at in the process. They showed up on time, they performed the work flawlessly. They gave me a quote the same day, actually immediately after they looked over my job which I have never heard of. I was very impressed with TerraFirma and highly recommend them.

Great expedience, very knowledgeable and helpful .

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!

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.

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.

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.

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”.

Terra Firma is professional and operates with integrity

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.

Bailey came out to do an inspection of our foundation to let us know what shape it was in and what kind of work might need to be done. He was thorough and honest about the condition of our foundation so we could make informed decisions about next steps with our property.

Jayden inspected my house and gave a thorough report of the findings. I’m very happy with the service, and would call again if needed.

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.

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.

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.

It took awhile to schedule due to them not having enough employees to cover Oregon and Washington. We had this done 10 yrs ago by them to the part that needed it and back then they didn’t tell us that the rest of the house could shift. I wish back then they could’ve put the piers all around the house so all they would have to do is just adjusted it because this time around the expense to do the whole house was something we didn’t expect and opted to do the part that really needed it the most. When we do sell our home, this will be something that we will have to disclose.

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
