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.

Reviews

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.

My house in Roseburg had sunk in two directions. They did exactly what the contract called for: the warranty can't be beat. (75 years!) Gave me the original documents of all the engineering and county permits. Very professional and pleasant, explained everything as they worked, left the place immaculate, even cleaned things like the driveway and replaced rock on a path that had been walked on. If a homeowner needs foundation work, this is the company to call. (roseburg)
Bailey came out to do an inspection of our foundation to let us know what shape it was in and what kind of work might need to be done. He was thorough and honest about the condition of our foundation so we could make informed decisions about next steps with our property.
I met with Seth and he represented the company very well.
Seth from Terraferma came to my house on time gave me a fair estimate and recommendations. There was no pressure. He was courteous and I have no hesitation in recommending Seth and his company Terrafirma for any future work.
They were very thorough in their work and Tieran (?) was able to take the time to explain what they were doing. I was quite pleased.
Very helpful, and very very inexpensive, they actually did not charge me for the help they gave me, that is hard to find these days!
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.
Noah did an excellent job of inspecting the crawl space, then providing a very thorough explanation of what was found, along with the options for dealing with the repairs.
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.
Charlie was our technician. He did a fantastic job, great with communication, and was VERY professional! Took before and after pictures and explained exactly what he completed! A++
Great job!
From the initial call & explanation of their services, I knew this was the company we wanted for our foundation issues at our house. Their follow-up & timely estimation process just made things great. Everything was also explained in exact detail. They were very accommodating to our schedule. The work began just a few short days from deposit. Collin & his guy that came out to do the job were very clean, thorough, & knew exactly what to do. The center of our house was 1.5” lower than everywhere else. It actually caused an atrocious squeak from the framing whenever there was movement near. That quickly went away! This needed to be done to install several new doors & jambs in the hallway. Several weeks later, there is still no squeak, the floor feels far more solid, & we have new doors that function flawlessly because of the work they did. If you EVER have a any sort of foundation problem, do no hesitate to reach out to them. & this is coming from a contractor. Every point of contact I had with them was pleasant. You just can’t go wrong!!

They raised & leveled areas of my patio that had sunk due to poor soil prep by the builder (Shea Homes, which refused to accept responsibility for their poor construction). However, the salesman made all kinds of promises that were unrealistic and the patio looked worse than it did before the repair (small cracks became quite large and obvious, though filled with material). The crew worked hard and did their job well but it was impossible to fulfill the salesman's claims. To their credit, they tried hard to fix it but couldn't, and so refunded my down payment. Very honorable and professional (except the poorly trained salesman), so I have them 4 stars.
Terra Firma was great with scheduling, and the work completed. They had great communication and explained the work in detail. Great company to work with.
I reached out to TerraFirma Foundation Systems to have them come look at my foundation. They were able to get me on the schedule within the week. Seth showed up on time for the appointment and got right to business. He walked me through what he was going to do and what he was looking for. He was very professional and polite. He even took his shoes off outside everytime he had to come in the house. Which is a big deal to me. When he finished the inspection we sat down and went over all my options. The whole experience was easy and I didn't feel taken. I would highly recommend Seth and TerraFirma.
Seth gave me an estimate on my crawl space. He arrived on time and gave me a courtesy call before his arrival. Seth was very thorough in answering my questions. The pictures he took were very detailed. Seth was also courteous and professional. Thanks again for your patience and coming out for the inspection.
Our experience with TerraFirma was great from beginning to end. They were very fast, efficient, clean and courteous. We had the crawlspace encapsulated and our whole house smells and feel better. No more mold and bowed floorboards. And they were cheaper than the competitors. Thanks, guys.
Excellent company to work with; we were out of state during our project and the company reps were excellent in communicating with us. Would highly recommend them!
Noah did an excellent job of inspecting the crawl space, then providing a very thorough explanation of what was found, along with the options for dealing with the repairs.
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.
Thank you Seth for your help in obtaining a fair and complete estimate on the project to stabilize our cracked driveway ! I appreciate your approach and your awesome personality!! A+++ job😁
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!
Appreciate our service tech Jon S. We had scheduled an annual service check up on our sump pump system. Jon was friendly, communicated well, arrived when he said he would, spent time asking and answering all my questions. Made recommendations for service and pump and took his time to do the job right. Once our old system was replaced he showed us the updates and let us watch him stress test the new system. While we have had multiple contacts/engagements with TerraFirma since we bought our house in 2018, we have been most impressed with Jon and his overall level of service and knowledge and look forward to another year of a water free basement....even in the worst storm conditions! Thank you!
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.
