We are returning customers who purchased 2 Garaga insulated doors a couple of years ago. When we recently decided to change our loud noisy chain driven openers we didn’t hesitate contacting Cliff’s. the installation was done professionally and I’m amazed how quiet these openers are. Wish we would have bought them when we had doors installed.
Thanks for the great service.

Cliff's Overhead doors attended to my needs in a timely and professional manner coming through with exactly what was needed. Additionally staff took the extra steps to make sure the existing automatic door opener was adjusted to the optimal settings. Field staff made sure I was satisfied with everything as part of their service protocol.
Truly appreciate this level of professional service.
