Customer Testimonials
Such a amazing experience! I have not always been lucky with contractors, but Josh and the rest of the team from Colorado Siding Repair were always so prompt and helpful! I was not able to move forward at this time, but will ABSOLUTELY be calling them in the future for my siding project.
Great experience with CO Siding Repair. The person I talked to over the phone was very pleasant and helpful. Cash came to evaluate some issues with my siding and trim - he is very knowledgeable and truthful. I look forward to working with them when the time comes since he indicated I have a few years left before I need to consider replacing boards. Thank you CSR!
Great experience with CSR. Josh and the rest of the team were always available. The guys who performed the repairs were friendly and I have no complaints on workmanship. Our trim repair looks perfect and they did an A+ job caulking and painting. I would definitely recommend their services and would use them again myself.
Josh went the extra mile to help me very knowledgeable and professional
