Serving The Denver Area & The Front Range Since 1974
We are the only front range garage door company that is IDEA accredited.
Colorado Garage Door Service was founded in 1974 by Russell Dunn Sr. as Denver's first "garage door service" company.
Russ's vision was for a company that helped people solve their garage door repair needs with timely and affordable solutions.
That vision is still alive today and continues to be carried out by his son John Dunn.
As the years passed Colorado Garage Door Service has evolved, today we not only repair doors we also are retrofit experts.
We solve the issues that most companies are unwilling or unable to handle. Our sales team is comprised of former technicians and installation experts that have over 90 years of combined experience in the door industry. We employ highly trained and certified technicians and installers that know how to get the job done perfectly every time.
Colorado Garage Door Service is proud to carry our founders vision into the 21st century.
