Service Area

Exceeded expectations in quality and time frame

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.

Skylar was wonderful to work with. Was very professional and did a great job with raising our concrete pad.,

Thank you Andrew K for doing an excellent job smoothing out our sidewalk. There were extra challenges because of tree roots but Andrew thoughtfully came up with effective solutions and minimal grinding. He was on time, efficient, and very helpful. A job well done!

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.

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!

Arrived on time finished in one cleaned up everything

Absolutely fantastic

These guys are great! Skyler explained the process and did a great job on a complicated floor. I would recommend them anytime.

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”.

A fantastic company,staff and did excellent job on my house.

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.

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!

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.

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!

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

Prices in line with other estimates, amazing customer service!

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.

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!

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.

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!

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.

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.

Tyler came out and did a great job of thoroughly going through the house and taking measurements and pictures to document what need attention. He walked me through options and gave his recommendations. While I had other bids, he kept in contact and checked in to see if I needed anything else. He did a great job working with my unique situation, never pressuring me to go in any other direction then what I comfortable with.

Then Victoria was great is getting everything set-up and connecting me to the crew that would be out to work on the project. They were there promptly the day as scheduled, which I appreciated.
They did a great job of walking me through the process and explaining everything that needed to be done while I was working.

They were fast and communicated clearly throughout the process and made sure I was there when they finished up. They cleaned up better then I expected considering they had to dig up a lot of soil and replaced the fence without it even looking like it was moved. I was able to get back the 1/2 an inch or so back from the chimney moving away from the house, so I was very happy about that! I would highly recommend them again and if I need the house foundatio repaired, would definitely call them back.

Time will tell if everything stays where it is, but so far it's been a wonderful experience. They were competitively priced but seemed like they wanted my business more then the others and made me feel valued.

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!

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 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.

The crew that did the work were great and did a GREAT JOB.

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.

We had some basement flooding in our house and after learning the cause, we started the work of getting quotes and inspections from Foundation specialists. When we called TerraFirma, Bailey was able to make time for our inspection within the week. From the jump, Bailey was very communicative, and set expectations upfront. He asked what was going on, looked at some suspected intrusion points and then let me know he'd carry on with the inspection and would let me know when he was ready for me. No awkward standing around or wondering how long it would take. Bailey was very thorough with his inspection and had an impressive presentation once he'd made a diagnosis. He told me his ideas and then asked me mine and we both felt good about the plan walking away from it. Ultimately our timeline didn't work out and we personally had to go a different direction, but if it did I'm confident we'd be in good hands with Bailey and TerraFirma!

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.

Jaden came out and reassured us that our foundation was good but our garage floor is settling.
We look forward to working with Jaden and Terrafirma in early summer to fix the problem.(Too difficult to move everything off garage floor this time of year)
Thanks again Jaden for your professionalism.

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

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!

After I bought a 115 year old house built partially into a hill near the top of Council Crest in Portland and discovered that the walls bled water when it rained, two walls were built into a hill and had endured the pressure of water and mud for a century, causing cracks and turning the foundation to crumbles, I called Terra Firma when an neighbor with an old house told me about her experience. Terra Firma has a great reputation. During the first meeting, Hannah walked the property and made a detailed proposal, explaining how Terra Firma would ensure that the walls do not cave in by shoring them up and anchoring them, supplemented with a vapor lock system to keep the water out of the house. NO MORE MUSTY SMELL, THANK YOU! Hannah explained the plan thoroughly, using her iPad to ensure that I understood. It could not get any better than this...I signed the paperwork immediately and contracted for the foundation repair and upgrade. This week, Geovany and his team spent four days working very hard and very smart to finish the project on time, and without any hitches. And they were working hard, very thoughgoing and steadfast.

I am extraordinarily pleased with the work of the TerraFirma team, and how they did it. It is obvious by looking at the work that my basement walls are solid, secure, and dry.

THANK YOU TerraFirma!

TerraFirma Foundation Systems is excellent at basement waterproofing. Be sure to ask about all the available options so you can choose the one that’s right for you. The company is very capable, but it’s important to do your research before making a decision.

The crew—Antonio, Jessi, and Casey—worked extremely well together. Antonio is especially sharp; whenever I suggested an idea, he immediately understood what I meant and offered an even better solution on the spot.

We wanted the best and we got the best, we didn't even call around, we called terraFirma. We.live on the Oregon Coast, Beaver, Oregon. Casey came out and was here for two hours. He went under our 102 year old house and came out with pictures. He immediately had several options with prices, we were impressed already. We called him the next to say we wanted the biggest one. 21 smart jacks, a main beam replacement, total encapsulation with dehumidifier and sump pump. TerraFirma scheduled us for the next month which for us was extremely fast, we counted the days and as said, Aris, Brad and Jose were here right on time. To the owner of terraFirma, these young men should be commended for their professional, excellent work ethics. They were all very polite, very hard working young men. I would come out of the house and they would all wave and say good morning. Even in the afternoon they would wave to me. These three men spent 8 days under our house on their stomachs, sides and backs, hauling everything out in trash bags (about 50) and the then the rock that they hauled under for the trench, all while laying down because of the foot and a half clearance under their. I'll get where I'm going here, Casey, Aris, Jose and Brad were all excellent and I'm sure you're very proud as I am honored to have met and kinda know them. Thank you all, we are very impressed with our crawlspace. Jeff and Ana De Lanoy

Good job it looks great and I would definitely recommend your company

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!

Mike, Steve and their crew from Terra Firma were outstanding. They were professional, on time and did some amazing work. I was very impressed with how they answered my questions and their quality of work. I would highly recommend Terra Firma for any of your foundation needs.
