Service Area

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.

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.

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

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.

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.

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!

James and his crew were efficient, kind, and exceeded my expectations. My foundation was needed piers both outside and in the basement, yet they were quick and cleaned up. I even noticed a change in my home’s interior when it was fixed! Cracks closed up. They took care of the whole process, including permits and inspections. And, James communicated, including walking me through, clearly listening to my responses. I recommend TerraFirma, especially James who was the foreman on my job, especially to those who want to be respected, want to understand what is happening, and want good communication throughout the job.

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.

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

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.

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 a pleasure to work with and demonstrated a high level of professionalism. He was patient in answering all of my questions and displayed extensive knowledge and expertise. He provided three separate proposals for foundation repairs.

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.

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

The Terra Firma team of Luis Juarez, Jose V., and Jorge D. were very dedicated and thorough in the crawl space encapsulation project at our home. They worked long hours to get the project done well and on time- as promised.

Extremely professional, and above and beyond in their work.

They make it all easy. Not just good work, they have great process. I do recommend this group of people highly.

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.

Very professional hardworking crew that put my sub pump in. Told me what they were going to do, kept the work area clean and had the job completed in a timely manner. Would highly recommend them.

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.

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.

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!

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

The guys were real efficient and professional. We’ve used Terra Firma for close to 10 years and it’s always a positive experience.

The whole process was seamless - from our initial proposal where Hannah answered all of our questions and did a thorough assessment of what was needed to Antonio, Kameron and Jesse who did a great job on our encapsulation project. They showed up on time, were professional, very informative, cleaned up when completed, and were a pleasure to work with. Would recommend their services!

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!

Terra Firma was such a professional business to work with. Their technician did a comprehensive diagnosis of our foundation and the team that came to fix our foundation did an incredible job! So thankful to know our foundation was fixed and passed all inspections.

Excellent team! Great attention to detail. Courteous, eager to please!

Prompt, thorough, asked great questions…with great attitude and smile! TerraFirma has an awesome employee! Noah is a keeper! He deserves a raise! Keep up the great work!

This may not have been Terrafirma's biggest project but it was big to us. From the very beginning of diagnosis, estimates/proposals, the project management and communications, hand digging and cleanup, the entire crew made this stressful and expensive project very easy and seamless. Thank you Patrick, Brent, Mechelle and on site laborers(sorry I didn't get their names) for all of your amazing help.

We had Tyler from TerraFirma come out to bid fixing a standing water issue in our crawlspace. He was thorough (crawled the entire crawlspace), knowledgeable and responsive to questions. As a real estate agent having access to good contractors is vital, and his professionalism has placed TerraFirma solidly on our short list.

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

Fourth project completed by Terrafirma for our property and while not everything always goes according to plan, they make good and stand behind quality customer service. Today we had three amazing employees- Jorge, Juan, Alencio solve some tricky problems with a smile and positive attitude! So appreciate another solution!

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.

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 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!

This was our 2nd time using Terrafirma & we were satisfied with the work of Antonio, Jesse & Kamron. Antonio called us when they would arrive & apologized for being little late. They were done with our project…just as they promised. They also took time to walk through the project & answer our questions beforehand. And, they walked us through afterwards. They did a great job. Also, they tidied up after the project t was done. I would definitely recommend them to others because I trust their work.

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.

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.
