Very good experience from day 1. They ended up not needing one of the permits or a window brace like originally planned, of which both items were credited back to me. The installation crew was professional, efficient, and more than tolerant explaining all the little details of what they were doing while I watched the process. I really like that they live streamed their engineers the entire time for QC, and even had a third party review inspection. I chose TerraFirma over 3 other companies for the warranty terms and for them being a long established Oregon local business, and I am very happy with their work and crew. I hope to not have any future structural repairs done but if I do, I will 1000% hire them again. Thanks!
