"After looking for a couple of years and not being able to find a siding company that would smaller jobs, I finally found Colorado Siding Repair. They came out and reviewed the job to replace one wall of siding on my garage that was badly warped. I chose to use a different type than the original, remove a damaged vent, etc. and it came out perfect. They were prompt, kept the work area clean, did some additional finish details to make the front of my house look great. I had one small issue and they promptly came back out and fixed it immediately. I highly recommend this company (and have to several people). They are doing a great service by offering repair/replacement on smaller jobs."
