Thank you so much for the beautiful siding repair and the gutter work. Our siding matches perfectly with the old siding. The workers were efficient and clean. We would highly recommend Colorado Siding Repair!

Customer Testimonials
They went above my expectations and had to move a lot of my junk to do their job. Took care not to damage my roses which I had planted across the front of my house. When I called or texted with a concern, they would always respond quickly. I’m a stressed person and worried about everything, they helped by addressing all my concerns. So far this is by far the best experience I’ve ever had with hiring someone to work on my home. They treated my property as if it was their own!
Colorado Siding Repair is a rare company to find. Their willingness to get the job done right and continue to strive for complete customer satisfaction is unlike anything I have encountered in the construction industry. Cash and Paul are terrific human beings guided by their integrity and honesty. Despite several set-backs, they showed every day and always made sure we knew they were going to do everything they could to make us satisfied.
