Foundation Repair Contractors in Yakima, Washington

Expert Foundation and Basement Repair Near You

Yakima, Washington, experiences a mix of hot, dry summers and cold winters, which can take a toll on your home’s foundation. While the region doesn’t see the same rainfall as western Washington, soil movement caused by irrigation, seasonal moisture changes, and freeze-thaw cycles can still create serious foundation issues over time. Without proper protection, homes in Yakima may be at risk of cracked foundations, uneven settling, water intrusion, and structural damage.

Our team understands the unique soil and climate conditions in Central Washington and delivers long-lasting solutions to keep your home stable and protected year-round.

The Risks of Unprotected Homes in Yakima, WA

Cracked Foundations

In Yakima, shifting soil conditions are often caused by cycles of dryness followed by sudden moisture from irrigation or seasonal weather changes. When soil expands and contracts, it places stress on foundation walls, leading to cracks. These cracks may appear vertical, horizontal, or diagonal, each signaling different structural concerns. While some cracks may seem minor, others can indicate serious issues that require immediate attention.

If left untreated, foundation cracks can worsen over time, allowing water intrusion, pest entry, and further structural damage. Professional foundation repair in Yakima helps restore stability and prevent long-term deterioration.

Water Intrusion & Basement Issues

Even in a drier climate like Yakima, basements and crawl spaces remain vulnerable to moisture problems. Poor drainage, overwatering, or snowmelt can allow water to seep into lower levels of your home.

Excess moisture can lead to mold growth, poor indoor air quality, and damage to stored belongings. Preventative solutions like waterproofing and drainage systems help keep your basement dry and your home protected year-round.

Seasonal soil movement in Yakima, caused by expansion during wet conditions and contraction during dry periods, can place ongoing stress on your foundation, leading to cracks and uneven settling over time.

Don’t take our word for it, see what our clients have to say. From Yakima and surrounding Central Washington communities, our work speaks for itself.

I’ve had a great experience with TerraFirma so far. Seth Cunningham is the tech that we have been working with, he has thoroughly explained the issues we are facing with our foundation and the steps we need to take to salvage our home. Although this is a blow to any homeowner, I trust that Terra Firma is going to get us back to where we need to be step by step. Communication has been top notch, and I feel confident we are in good hands…… update!!! The work was completed by the crew, they were so professional and nice. Got the job done and were even able to eliminate one of the jobs because they were able to make it work and they made me aware of a leaking pipe under the house I didn’t even know was there. Invaluable!!! This is a very good company to work with, I really am satisfied.
So pleased with the total experience. We were provided with expert analysis of how to achieve stabilization of a concrete slab. Coordination between sales, planning and production was excellent. Technician was very proficient and friendly.
I've had multiple interactions and services (including sump pump installation) done by TerraFirma, all good experiences. However our last service which was an inspection of our foundation was exceptional and warranted me to write a review. Our systems design specialist Tanner Heinz who came out was courteous, knowledgeable, friendly, and respectful to our home. We felt like he wasn't trying to oversell, just telling us straight facts and honest opinion. We trust our home is in good hands and came up with a game plan. If I owned a business we'd be lucky to have Tanner as an employee. Highly recommend this company.
Seth came out today to check under my house to give an assessment on ways I can improve my foundation for earthquake protection. He was awesome. He was on time and very personable. He explained things (with pictures) very clearly and answered all my questions. I was very impressed. 🙂
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.
Seth visited our home to give us a quote on seismic retrofitting. He was on time (and made sure to call when he was heading our way), did a thorough assessment of our home, and was an absolute pleasure to work with. During the assessment, Seth patiently answered all of my questions. It was clear that he was extremely knowledgeable about the available retrofitting options and what best suited our home. The final proposal was easy to understand; it clearly outlined the work to be done, why it needed to be done, and how much various options would cost. Overall, it was an excellent experience.
Seth was amazing and really put in the work to figure out exactly what I needed done on my home. He was super knowledgeable and seemed to really care about my needs. I tried 4 company’s before terrafirma and will stop looking as I am sold on their ability and willingness to take care of my family and my home.
Great job Thank all you guys TerraFirma👏 keep going
Noah was extremely thorough and explained his findings clearly with optional choices of services that we needed with the pricing. He was friendly, courteous and easy to talk to. We would highly recommend Terra Firma. Noah is a very valuable representative of the company.
Quenton came to service crawl space sump. He did a thorough inspection of the whole space. Cleaned and serviced sump that was full of clay. Found issues and gave recommendations with pros and cons. He didn't push any unneccessary things. Took pictures of all issues and work and thoroughly explained everything. Installed a new dehumifier and removed old one and hauled away. Would recomnend this guy to anyone. I hope this guy is an example of how the business is run. Excellent job, very happy.

They did what they said they would do...(level my 24x22 patio) at the price they quoted. Nice
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.

Their salesman Sam came out to my property and did a great job answering any and all questions I had. He was very detailed and knowledgeable. He showed us a very cool informational video that gave me a lot more understanding of his scope of work. He was professional and polite. Would highly recommend!
Very knowledgeable and friendly employees Hard workers got it done in one day
Terra Firrma did a great job lifting a sunken step back to a normal step level. It is level and solid.
Five stars on all categories.
Charlie was out to service our sump systems part of our ten year warrantee. He was professional and worked quickly! He answered all the questions I had.
TerraFirma did some concrete work for us right up against our foundation and the end result looks amazing. They were very professional and knowledgeable, and I would definitely hire them again the future. Highly recommend them!
We called TerraFirma with a pretty significant problem. We had just purchased a home and were a bit misled on a couple of items. The basement and crawlspace were mold infested (which we did know). What we did not know was that at times of the year, there would be some standing water in the crawlspace. We also didn't know that the drain from the sump pump was actually underwater (adjacent lake), nor did we know the pool backflushed into that same line and actually would enter the crawlspace whenever that process occured. The crawlspace was unvented and unconditioned....the perfect storm of BAD! Our goal was to first remediate the mold and then resolve the issues that allowed the mold to grow in the first place. Enter Terra Firma. Tulane and Terra Firma stood head and shoulders above every other company I spoke with. It wasn't jus that they were going to fix it- we literally walked through every step and every product-I knew what I was buying before we started. The crew was professional, on time and did exactly what they said they would do and in the time frame promised. With Terra Firma, we waterproofed and encapsulated our crawlspace, we insulated the crawlspace, we installed new sub floor drainage with new sump pumps with battery backup to lower the water table under the house (that now drains above the high water line), we installed new structural floor posts where others had rotted, we installed a bypass for the pool overflow and we installed dehumidification and we are in the process of now conditioning the space. Terra Firma led the way and did an excellent job both on the communication and on the installation (at the price originally quoted!). I would highly recommend this firm for anyone with complex and challenging crawlspace issues. Great work and fantastic team from start to finish! Bruce McKee
Seth was knowledgeable, very experienced and the price was extremely reasonable. I had plenty of options to choose from. I also met with the competition and it felt like they were recruiting high schoolers to do their estimates.
