Crawl Space & Foundation Issues in Pasco, WA

Seth Cunningham was super. Arrived on time, called prior to arrival to confirm, was friendly and informative. Listened to my concerns and provided helpful suggestions. Thank you so much, Seth!

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!

Terra Firma did an excellent job on our porch beam & supports repair. Their estimator was especially helpful. The workers were very nice & worked hard. We appreciate Terra Firma’s diligence to safely do our repair. We would highly recommend Terra Firma. Thank you.

Elijah did a fantastic job breaking down everything going on in my crawlspace and providing the estimates to get the repairs.

Great; competitive price, installation went great, friendly and responsive staff in person and office. They made a drainage system for our crawl space with a sump pump.

We are impressed with the knowledge and thorough and professional assessment of our home’s issue. Seth Cunningham was great at communicating information and providing answers to our concerns.

Would highly recommend these fellas. Had two separate guys out to our place (Sam, and Tulane), and they both killed it. They gave us total peace of mind in moving into our new home. They assured us that there was a solution to our foundation problems and gave us an excellent quote on the project. Definitely planning to go with these guys for this project.

***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.

This review is based on the customer service. We had a water intrusion problem in our finished basement after excessive rain just before Christmas. We called around and TerraFirma was one of the few places that could send someone within a week. Travis came by and gave us his honest opinion and suggestions without cost. Options included digging up the basement and adding a sump, or doing some simple exterior projects to keep water from draining toward the foundation. I appreciate Travis providing us options that did not require TerraFirma. While we ended doing the exterior work to keep water away from the foundation, we would recommend them for their great customer service. If we ever have need for foundation repair, we would not hesitate to call them in the future.

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.

Seth has been really awesome. He is professional and very patient. We had many questions. He took time to answer them all and come over twice to make sure the detail were accurate. I'm happy to have met him and look forward to our basement being fixed!

These guys replaced the foundation along one whole side of my house. Then they installed a drainage system and sump system beneath my home. I couldn't be happier and it was worth every dime I paid! Great work, great crews, great subs, everybody from the switchboard to the project managers are the utmost in professionalism. If needed I'll hire them again.

During my search on-line for a source of repair for cracks in our cement driveway, I found the TerraFirma Foundations Systems website most appealing. I invited Seth, Systems Design Specialist, to provide an estimate. He provided a thorough explanation of TerraFirma's method for repairing cracks. He examined the driveway, made the necessary measurements, and provided a reasonable estimate--considering the extent of the current damage. The project was scheduled to be accomplished in two phases. Phase 1 scheduled Nov 2024: foam injection to stabilize the cement pads thereby preventing further damage. Phase 2 scheduled May 2025 or sooner depending on the weather. This delay was a consequence of my procrastination to tackle the project earlier and TerraFirma's determination to ensure the repair would suffice to fulfill their 5-year warranty. Employees Robert and Elijah arrived on the scene as scheduled. While I observed their work, they impressed me with their professionalism and efficiency as an experienced team. They put forth an obvious desire to do an exceptional job thereby giving me confidence in the performance of the task and TerraFirma overall. Standby for my review this summer regarding Phase 2.

Called TerraFirma to take a look at the concrete steps that have been settling for years. Bailey Mercer is very professional, knowledgeable, and easy to work with. He answered all our questions, and addressed our concerns. At the end, he presented us with 3 different solutions. There was no pressure to pick one, or pick the most expensive one, or pick one within the hour or the deal is gone. We had the weekend to think about it. Bailey did a follow up call as promised, and answered even more questions - all to our satisfaction. I will update when work begins and at its conclusion. Bailey should get a surf and turf dinner, not just a lunch!

Seth arrived promptly, as scheduled. He efficiently measured the elevation difference of a wall section what was sinking. His proposal to repair the foundation was significantly lower than I expected. The investors chose to not purchase this building due to other issues along with the foundation repair costs. Seth is friendly and well informed of his product. I likely would have welcomed TerraFirma to perform the necessary foundation stabilization repairs had we purchased this building.

Eric was incredibly knowledgeable about home structure and foundation support. You can tell he genuinely cares about his line of work, and helping people find peace in stressful situations.

Seth Cunningham has been extremely helpful for my business. He is always honest even when it means they don't get a deal. Just today I had a home inspection that called out a foundation cut under a home. After Seth inspected it turns out that is how the home foundation was built. Such an honest guy. This helped the deal proceed. He also has fixed multiple jobs for me including an entire foundation on a home for me that cracked, as well as jobs like full basement water systems and water intrusion systems. They can even repair driveways and walk ways. These guys are legit!

Very professional !! They know what they're doing!! They also made sure that the place they were working was cleaned up and left nice. 😊

been just over a month of hard rain and no leaks, guess it works

Scheduling was a breeze and they got out to my house within days. Bruce was very thorough and thoughtful in every aspect of the inspection and estimate. He let me know all the steps and information involved. He is kind and "real" with you every step of the way! Thanks Bruce & Terrafirma!

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

Very professional and efficient from start to finish. My front porch had settled around 6 inches on one side, and TF was able to bring it up to level, and was very careful to maintain a slight grade from back to front for water to run off. I was very impressed by their knowledge, friendliness - and the result was very impressive. It was a very good decision to to go with Terra Firma.

I had a sidewalk and patio leveled. The team was professional and their work was exceptional.
