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.

Without proper protection, homes in Yakima may be at risk of cracked foundations, uneven settling, water intrusion, and structural damage.

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.

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.
2/16/26 update: My sump pump broke in December due to the high level of iron in the soil under my house. Terra Firma responded quickly and replaced the pump with no issue. Great customer service and a great team / experience! Thank you Terra Firma!

Seth has been amazing to work with! I have been working with Seth on designing my crawlspace drainage system. Seth has been extremely helpful, patient, and professional. I've pestered him every day, multiple times a day with questions, asked for revisions to my quote, clarifications, and have been an all-around pest. Through it all, Seth has been responsive, communicative, and thorough. The work is scheduled for Mid-May 2024. I will update my review after the work is done with how it went with the crew and the job they did.
Excellent experience with TerraFirma. Noah Bryant arrived on time, sent a helpful reminder, and spent nearly 3 hours thoroughly inspecting inside and outside. He took photos, clearly explained crawl space issues, and offered honest recommendations with options—no pressure. Very professional and sincere. Highly recommend!
Very thorough and informative.
TerraFirma made a major error when fixing the foundation for the overhang of our Enumclaw Plateau Historical Society museum. The posts were not properly spaced, giving the front of the building an uneven appearance. When the error was pointed out to them, they admitted it, and apologized. They paid the repair costs without argument. According to a businessman on our board, this is an unusual occurrence. I want to give them kudos for their management acting with integrity.
I purchased two waterproofing systems from them a few years back. After the rain the past couple days its time to leave a glowing review. They did an interior drain in my basement and a separate drain tile system in my crawlspace. Both systems have been working flawlessly for 3 or 4 years now with zero water intrusion into my basement that I totally renovated after their install. They've also come out every year as promised for servicing. Thankful for connecting with them. After hearing the river of water enter into the pump and it go off every minute or so for nearly 12 hours yesterday, they deserve 5 stars. I would recommend them to anyone.
Update:
Robert and Jacob showed up and fixed my sagging kitchen floor. Punctual, professional, thorough, fast! Highly recommend TerraFirma to anyone needing foundation services. Overall total experience was top notch!! Thank you TF!!

Noah arrived punctually and impressed from the get-go! He was here for an estimate visit and began with the explanation of how the appointment would be performed He was very thorough in explaining every detail and options available to me. Although I have not committed, Noah’s professionalism and knowledge were on point and I am definitely going to consider using Terra Firma for my sagging kitchen floor. Stay tuned…
Very knowledgeable and professional
Good customer service, good quality work and timely.
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.

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 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!
Seth C. was really helpful this morning. It has been raining so much lately and he was able to walk me through all the issues my daylight basement and garage can have and how TerraFirma fixes them. Really appreciate you--/thanks so much Seth
Seth came out to evaluate my foundation and gave me one of the most thorough and honest assessments I've experienced from a contractor. Professional, communicative, and zero pressure — he clearly takes pride in his work. I didn't move forward with the project through Terra Firma, but that has nothing to do with Seth or the quality of his visit. Highly recommend requesting him specifically. 5 stars.
Great expedience, very knowledgeable and helpful .
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.
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. 🙂
Robert and Jacob came out on a cold, breezy December day and injected the company's foam-brew under our one-hundred-year-old staircase, raising it nearly 1 inch and thereby reconnecting it to our home! No small feat! As a realtor who has recommended TerraFirma to several of my clients, I've come to expect this kind of service, but I wanted to call out the guys for their professionalism and resolve when rain threatened. They also had great info (pics, measurements, etc.) from the estimator, making the project well-organized and timely. Well done!! Highly recommend.
Arrived on time finished in one cleaned up everything
Update: they sent someone back out to inspect the tree and work. Wouldn’t pay for someone to make the tree look nicer and mentioned they could give us a gift card or something for the trouble but never followed up with that. Ended up hiring an arborist on our own.

Estimator Derek was very friendly and helpful. Had a much better experience with him than I did with Groundworks. Quote was better too and took about a week to get on the calendar. Was able to get on the schedule fairly quick and they even called with a same day cancellation the Friday before we were scheduled.
Work that was done was okay, they were able to lift what we wanted on the main driveway and did their best in front of the steps. Unfortunately they used a jack, which I wasn't expecting, and ended up cracking the slab in front of the steps. It's in the contract that they're not responsible for this so nothing was done to mitigate it. Also a slab next to the large one lifted developed a large crack after they applied the stabilizing foam to the lifted slab.
Other issue is that they said it wouldn't be an issue to have the truck down our driveway as they have more than enough hose to work with. Unfortunately they backed the truck right into our magnolia tree and when they were pulling away it ripped a large chunk of branches out.
