Leaking basement threat in Tacoma and Kent

Situated at the southern end of Puget Sound, Tacoma is surrounded by stunning natural beauty, including lush forests and rugged coastlines. Rainy climates in cities such as Kent and Tacoma can lead to moisture infiltration, which can cause leaking basements, mold growth, and rotting of wood structures in your home.

Foundation challenges NEAR Olympia and Auburn

Tacoma’s hilly terrain poses challenges for homes built on slopes. Soil movement, erosion, and landslides can threaten the stability of foundations, particularly in areas prone to steep slopes or unstable soils that can also be found in Olympia and Auburn.

Uneven floors are also a common issue found in houses throughout Tacoma and Federal Way. Keep in mind that this may not be a foundation issue but a possible problem associated with moisture in the crawl space underneath.

Don’t take our word for it – see what our clients have to say.
Throughout the Tacoma area, from Kent to Puyallup, Federal Way to Olympia, and beyond, our work speaks for itself.

We have had thoroughly excellent service from TerraFirma since October, 2017, for a variety of issues involving flooding and foundations. TerraFirma seems to us completely competent and reliable. We would recommend this company to one and all.
They follow through and are very helpful. We also used them 5 years ago and do very happy. I respect them and what they do. Joanie Chambers
I'd been putting off fixing our sunken garage for a few years. With the flooding seasons getting more and more distinct, it was time. i called a few places, and TerraFirma not only had the best resources to provide an accurate quote, they were also the best value. Both Sam during quotation and Zach during install did a great job balancing the needs of the solution with the status of the house, and in the end I couldn't be happier.I can't say I'm looking forward to having more foundation repair projects in the future. But in the event I do, I know where to go to.
We lost power for 7 days & our battery backup for the sump pump didn't miss a beat!
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.
I had a positive experience with vapor barrier application to my basement walls, a draining system install that wraps around the basement walls, installation of a sump pump, foundation crack repair, sealing/ vapor barrier install in a crawlspace.
Seth was great explaining the whole process!!!
I got a bid done by TerraFirma today. After speaking with Seth today. He answered my hundreds of questions and cured and worries I had about foundation issue. He broke it down and explained the whole process from start to finish how to remedy my foundation problems. I like the fact that they were punctual. They were right on time at the scheduled appointment and wasted no time trying to figure out a solution for my problem. The prices He gave to me were really fair and the depth of knowledge was very useful. I feel very confident that TerraFirma should be able to fix my settling / cracked foundation problems.
Seth from Terra firma is great I highly definitely recommend him. Thank you
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.
