    Jami E. of Oakland, OR

    Customer Testimonial

              We are currently doing our own independent research to make sure this is the best option for our house. I'm feel great about how Casey explained things to me, I just like to do a little of my own research on the side for piece of mind. Casey gave us more than enough information during his visit so we now have a great understanding of where the project rooted from and the next steps would be. Casey was extremely professional and clearly knowledgeable in the field. The long term guarantee is the most comforting thing for me and my family as we now know homes are constantly shifting and changing. Thank you TerraFirma for everything.

    Ian G. of Bend, OR

    Customer Testimonial

              We were looking to sell the home. While we were getting initial inspection on the value of the home, we were constantly told to get our crawl space finished. In our mind, crawl space finishing, especially in Bend, OR seemed silly. This is why we were so happy to have Chris as our representative. After he went through his presentation and talked about the benefits of having a finished crawl space, we now saw what the inspectors were talking about. We were able to sell our home for about 10% more than what we initially though and a lot faster than we would have otherwise. Chris is a great representation of your company and we are so glad we called TerraFirma.

    Customer Testimonial

              I don't think many people understand the importance of below the home health to a house. We sure didn't. I had always focused on making things look better and more visually appealing but never got the root of the problems. Patrick Dunn gave us great information through and wonderful computer presentation about the science of encapsulating your crawl space and the benefits of doing so. We were so impressed. Patrick is a pro in the industry. I have nothing negative to say about everyone I came into contact with at TerraFirma. We are so happy to have worked with your company and are more than happy with the outcome of our crawl space.

  • "Casey and TerraFirma is the best option." Read More

    Cameron H. of Talent, OR

    Customer Testimonial

              In my book, there is no such thing as a 10/10 but Casey came pretty close to it. I had received other bids for my project and some were 4x the amount that Casey has proposed and I still felt Casey and TerraFirma was the best option. His presentation was very thorough, explained to me exactly why I should not only go with their company but their PRODUCTS. Casey really believed in the products, that they were on the cutting edge of the industry's technology and that along with a nice warranty, this was THE BEST option for my crawl space to date. I couldn't help to agree. The only thing that would have made things better is if they made hot chocolate while we were discussing the project details.-kidding. Thanks guys.
