Our garage door is just over 6 years old (builder's special - heavy wooden double car door) that has never been serviced.
The cable on the left side became frayed, and was no longer level. It wasn't until two broken rollers broke recently that made the door sound terrible that I finally decided to call for service. I chose Markham Garage Doors because it is a local company and had great reviews here on Homestars.
Kevin answered the phone and was here in less than an hour. He worked quickly and efficiently, and didn't mind my curiosity as I chatted with him. Although only 3 rollers were broken, I asked to replace 6 instead in case one of the remaining others might break soon.
We will definitely be calling Markham Garage Doors again in future when it comes time to replace our garage door. Thank you again Kevin for the great service and answering all my questions.
