foundation repair SOLUTIONS

Cracked foundations, nasty crawl spaces, and musty basements can be a nuisance for homeowners. The foundation repair specialists at TerraFirma can repair the structural integrity of homes. Our expertise focuses on identifying and resolving various issues caused by shifting soil, water intrusion, or age-related wear. We’ll come to your property, diagnose the problem, and start a repair plan to get your house back in shape.

There are several tactics that our foundation repair specialists will implement based on the assessment and analysis of the foundation. These may include the following:

  • Foundation anchors for extra support
  • Wall stabilization to prevent bowing or leaning walls
  • Vapor barriers to manage humidity levels and impede water damage

We offer free, on-site estimates to assess the damage and offer reliable solutions to stabilize homes in Portland, Seattle, Tacoma, Roseburg, and across the Pacific Northwest.

Our foundation pier solutions are tailored to meet the unique challenges of the Pacific Northwest’s soil conditions, providing peace of mind for homeowners.

PUSH piers

If your home is settling into unstable soil conditions, push piers are the least risky solution because they are driven all the way to bedrock or a stable soil layer. TerraFirma’s push piers are tested and proven.

  • Fast, seamless installation
  • Permanent stabilization
  • Extends to greater depths than alternative options
  • When soil conditions are unknown, push piers are the preferred solution because they are driven all the way to bedrock or a stable soil layer
  • Year-round installation
  • Installed in interior or exterior locations
  • Minimal excavation required

Pre-Construction PIERS

If you’re building to stand the test of time, TerraFirma installs piers pre-construction, or when the existing foundation has failed and needs to be replaced. Ask us about your pre-construction permanent foundation solutions for challenging builds. Excellent in both residential and commercial installations.

Grouted Micropile Tiebacks

TerraFima’s grouted MicroPile piers are typically used when challenging conditions-such as steep slopes, deep sand, rocky or wet soil, or complex geology-impede the function of other foundation piers. Capable of penetrating soil obstructions, we can increase the stability and load-bearing capacity of the surrounding soils.

Foundation Wall Stabilization

Cracks in your basement or foundation walls are a sign of foundation stress. Stabilization of foundation walls helps repair or prevent cracking or bowing walls. Ignoring these signs can lead to worsening structural issues, including water intrusion, loss of property value, and even safety hazards, which is why you should look into our foundation repair services. Proactively addressing these problems with our foundation stabilization methods ensures the long-term stability of your home and prevents costly repairs down the line. Each foundation wall repair solution is tailored to meet the specific needs of your home, providing peace of mind for you and your family.

Crawl Space Support Posts

When floors in the home start to sag, this may not be a foundation issue but a possible problem in the crawl space underneath. Homeowners in Oregon and Washington are very familiar with the damage our wet, damp, and expanding soils do to our homes. If left unchecked, these conditions can lead to wood rot, mold growth, and pest infestations, further weakening the structural integrity of the crawl space. Poor ventilation and trapped moisture exacerbate these issues, creating an unhealthy environment that can impact indoor air quality. Proactively addressing these problems with crawl space support posts not only protects your home but also ensures a safer, more comfortable living space.

Don’t take our word for it – see what our clients have to say.
From Roseburg to Eugene, Portland to Seattle, our Foundation Repair work speaks for itself

TerraFirma installed EverBrace on our hundred year old foundation. It was a cost-effective way to proactively prevent foundation failure while also adding waterproofing and earthquake resilience. TerraFirma was a joy to work with, especially considering the size and complexity of the job. Our sales person and project manager made it feel easy from the very beginning. The installation crew was particularly great, always arriving exactly on time, explaining what they were doing each day, and answering any questions. They went above and beyond to not only complete the project as planned (and right on schedule) but also took care to leave the site in better condition than they found it. It's clear that Rocky and Harley take pride in their work. Earthquakes now don't seem as scary, and we love our new clean and dry basement!
Bailey demonstrated exceptional attention to detail and expertise when inspecting the house foundation, ensuring everything was up to code and structurally sound. He addressed the issues I was concerned about and was very honest on his findings.
The crew that came out from Terra Firma Foundations was amazing. Explained everything so clearly that a dummy like me understood what they were they were doing. Answered all my questions. Cleaned up the work-site so it was cleaner than when they started and did an all-around bang-up job. In case you're interested in requesting the crew I had, the team was: (Timothy Cranley II, Jonathan Heredia, Jairo Torres, Rodolfo Ruiz, and Zack Etters.)
I hired TerraFirma to encapsulate my basement and crawlspace because my house is on a. slight slope and the rainy PNW winter was causing all sorts of humidity issues. Don was dispatched to my residence and was very professional in explaining all the options available and helped me select the best option for my situation. Scheduling was a breeze and the crew that did the installation was very competent. I worked with Timothy, Chris, Train, and Jairo and they were magnificent. There were some hiccups along the way, but the team took care of every minor bump and made me feel valued as a customer. There was very minor interruption to my life and the basement/crawlspace is even cleaner than it was before! On top of everything else, I believe the price was very fair for the work that was done. If I ever have any foundation/basement work to me done again, I will definitely reach out to TerraFirma!
I can't recommend TerraFirma enough. They took away all of the stress of having a cracked foundation We bought a 1901 house in Carlton. We didn't know that the vinyl in the kitchen was hiding foundation issues. From the initial walk-through, scheduling, and price, it was exactly as they said it would be. Jonah, John A and Matt we're extremely professional and personable, it was a pleasure working with the team.
Terrafirma repaired my sunken foundation, lifting the foundation back to where it should be. It is something that I thought couldn't be done but they did it. They are experts at what they do. I could not be happier.

Had TerraFirma come to our home for estimate to level our drive way, which had been "leveled" 2x prior and failed, Turns out, in less than 1.5 yrs, our home fell forward 1.78 inches and cracked our foundation in 3 places... YIKES! The work got underway once permits came in, the 2 crews did an install of 4 piers indide our garage and leveled a driveway, walkway and entry steps. Hands Down, we are beyond words Beyond expectations happy with our now Safe home!! If you need any of the services TerraFirma provides, hit me up... I will fill you in on how professional, respectful and knowledgeable their crews and staff are! In all 5 Star ratings, we wish we could give a 10+
TerraFirma was at my house quoting services and I was so impressed with the highly detailed quote that I started a random conversation about my work. I shared that I needed isolated foundations for CNC equipement. We ended up using their services for the CNC foundations and i couldn't be more impressed.
Installers were very professional. I asked for a few areas to be filled farther They made adjustments in areas that I asked gladly. I would recommend TerraFirm Foundation Systems to others. My back was out, the guys removed items from side of the house. Please give the installation team our thanks Everette
Walt listened to my concerns and did a thorough job of evaluating the foundation. When he finished, he took the time to explain what was normal settling, and what was concerning. He pointed out that I had a drainage problem around the foundation that needed attention, and might prevent the settling from becoming critical. I loved that he was not just out to sell me a service!!! I feel like I can trust his recommendations when I have him back to see if the new drainage solved the problem. Thanks Walt!!!
Workers completed foundation piling work in one day and did a great job.
I hired TerraFirma to do a seismic retrofit on my house. The entire experience was outstanding! They showed up exactly when they said they would. The job was completed in the expected time and they cleaned up after themselves. I feel like the cost of the project was more than reasonable for the peace of mind l now have, knowing l have done what l can to protect my home in the event of an earthquake. I would recommend them to anyone who is looking for a professional company to work on their foundation.
