    Roseburg & Medford’s Preferred Foundation & Concrete Repair Experts

    Southern Oregon’s diverse climate and soil conditions present unique challenges for homeowners in Roseburg, Medford, Grants Pass, Klamath Falls, and Coos Bay. Unlike the consistently wet conditions of Portland, these areas experience a wider range of temperatures and moisture levels, leading to varied soil behaviors.

    Inland areas including Medford, Grants Pass, and Roseburg often experience hot, dry summers followed by wet winters. This fluctuation in moisture content causes significant soil expansion and contraction, particularly in areas with clay-rich soils. This can result in foundation settling, cracking, and uneven floors. Call us today at (866) 486-7196

    From Roseburg to Medford, Klamath Falls to Coos Bay, and throughout Southern Oregon, our work speaks for itself.

    Technicians answered my questions and explained the process of expanding foam to my satisfaction. They were courteous and on time. The process was less invasive than I expected it to be. This is not a cheap fix, but wanted to have it done only once and not worry about it down the road.
    In response to TerraFirma: I met with another Lead worker and the Director of Production. Both very kind and professional The job will be completed. I am sure the new workers will do an awesome job. Thank you!

    TerraFirma, Luis and Crew were extremely hard working, professional, efficient and friendly! They got the job done! Thanks!
    I had a sump pump installed and these guys were fantastic from start of project to finish. Mychelle answered all my questions, Andrew and team were punctual, professional and got the job done fast, plus no mess. Thanks guys.
    Just had clean out of old duct work and old insulation, etc. plus encapsulation of my crawl space. The crew worked really hard and professionally throughout the 5 day process and the foreman kept me informed along the wife. Have worked with Terra Firma on several occasions: pier placement and jacks for house, french drain in crawl space, and replacement of sump pump, etc - alll involved from the estimators, the office personnel, and work crews have been excellent throughout.
    Looks good super fast job.
    Every person I dealt with showed a high level of professionalism and took the time to explain the process and answer all questions. The on-site crew all wore masks and were courteous and cleaned up all dust and debris. I would definitely use this service again.
    Astonishing. Clearly knowledgeable, didn't try to sell me anything I didn't need -- to the point of selling nothing but nevertheless spending many minutes walking around, inspecting thoroughly, and teaching me a ton. What a gracious way to do business. If I did need foundation work I'd want this outfit for sure. Thank you very much, Walt and your team.

    Friendly and got the job done fast and great results! Would greatly recommend them!
    TerraFirma installed Vuba stone on my patio. It was level for a few weeks after raising the concrete a few inches but started sinking a little. I’ll call them tomorrow 8/27/2026. Update: 8/31/2026 TerraFirma response time and follow through were excellent. Issue is resolved. Jeramie did a great job on getting my patio level again. I would use them in the future. Thank you.
