Keep Water Out of Your Basement with TerraFirma

Basement Waterproofing Customer Testimonial from Ken O. in Corvallis, OR

I was ready to transform our basement into the livable space that we had envisioned when I purchased the house 8 years ago. I met with 4 different companies about the best way to take a comprehensive look at regulating humidity, waterproofing and finishing. There were two companies that were able to do all three services I was looking for and Casey separated himself by his integrity, honesty, and professionalism. I never felt like I was being up sold or pressured into getting products installed that I didn't need or were not necessary. This went a long way with me and it was an easy decision to work with Casey and TerraFirma.
