Outstanding service! Prompt response time and quality work. I've worked with Cornerstone for over 10 years and they're the only garage door company I will use!

Great company! I recommend to everyone. Always they responded very professional with high quality! I gonna use again!

I cannot in good conscience recommend this company. I built two houses, and used Cornerstone Overhead Garage Doors for both houses. Each house had its problems within a few months after installation.
