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.

Seth came out to my house and was awesome! He was on time, polite and professional. The information was presented in a clear manner and helped us understand what our options were to achieve our house objectives. Definitely glad we had TerraFirma come out to give us a bid.
had leveling and damp under home issues. They completed work and are always quick to answers all concerns or questions. Thank you Terra Firma staff
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.
Seth Cunningham came for a site visit today at my rental home and was extremely professional and courteous. He explained the foundation water intrusion issues we were facing in depth and created a clear remediation plan at a fair price. I’d recommend Seth and TerraFirma to anyone needing building foundation services

Seth from TerraFirma did a great job in measuring and providing the estimate for our house. He was very patient in walking us through different scenarios and introducing the tech specs of the proposed solution options. Super helpful for us.
For Seth Cunningham: "You never get a second chance to make a first impression." Terrafirma should be very proud to have Seth Cunnigham as their first impression. Punctual, professional, personable, and very knowledgeable. Seth assessed our crawl space and provided us with a thorough explanation (photos) of the situation, options (videos) and itemization (documentation) of each potential solution. He is a delightful young man who I would recommend without hesitation.
