Crawl Space & Foundation Issues in Kennewick, WA

Kennewick is known for its dry climate, warm summers, and seasonal temperature swings. While the area doesn’t experience heavy rainfall like western Washington, soil movement from irrigation, fluctuating moisture levels, and freeze-thaw cycles can still create serious issues for homeowners.

These conditions often lead to uneven floors, moisture buildup, and structural concerns, all common signs of crawl space and foundation problems in Kennewick homes.

Foundation Repair and Soil Conditions in Kennewick, WA

Kennewick’s soil conditions can shift significantly throughout the year due to cycles of expansion and contraction. When dry soil absorbs moisture from irrigation or seasonal changes, it expands. As it dries out again, it contracts, placing stress on your home’s foundation.

The Risks of Unprotected Homes in Kennewick, WA

Cracked Foundations

In Kennewick, 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.

If left untreated, these issues can worsen over time, leading to structural damage, water intrusion, and costly repairs.

Water Intrusion & Crawl Space Issues

Even in a drier climate like Kennewick, crawl spaces and basements can still experience moisture issues due to poor drainage or overwatering.

Excess moisture can lead to mold growth, poor indoor air quality, and damage to your home’s structure and belongings.

Don’t take our word for it, see what our clients have to say. From Kennewick and surrounding Tri-Cities communities, our work speaks for itself.

Great expedience, very knowledgeable and helpful .
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!
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. 🙂
Very thorough and informative.
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.
Good customer service, good quality work and timely.
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…
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.
Quoted me $80k for proprietary solutions to some problems I do have, and some I don’t actually have. Took a bunch of pictures, showed them to me, but conveniently never sent them to me and thought it was weird I asked for the proposals to be emailed to me.

I decided to get a few other opinions and boy am I glad I did. Lying to me is one thing, but doubling down on the phone when you call me to ask if I’ve had time to consider scheduling the work is another.

I vote with my wallet and I have zero respect for a company that uses scare tactics or attempts to fudge the truth when they think the consumer isn’t educated enough on the subject to put two and two together.

Being a homeowner is hard and expensive enough… but then you have to navigate whether or not someone is trying to help you or empty your wallet for commission. This was arguably a worse experience than being a woman at the car dealership. No, I am not interested in purchasing blinker fluid…

Edit: With a continuous improvement mindset, I do appreciate someone at Terra Firma reaching out to me directly to understand the details of my experience so they could work to resolve internally.
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.

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.
Very thorough and informative.
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!

We worked with TerraFirma on a complex project involving installation of their EverBrace wall stabilization system. The project took a lot of planning and communication leading up to installation, plus a 3-week on-site job. Everyone I interacted with at TerraFirma was warm, communicative, respectful, helpful, and creative in solving any issues that arose. I could not have asked for a better customer service experience. Our project was expensive, and a stressful endeavor for a homeowner, but I felt I was in good hands from start to finish with TerraFirma. Not to mention that the EverBrace solution saved us tens of thousands of dollars. I highly recommend this company.
