I had Markham Garage Doors install my new garage door opener. I booked my appointment on a Monday and was given a quote 30 minutes after I had spoken to someone at their office. Once I approved the quote they called me promptly to book the install. That Wednesday Avery installed my door opener in a few hours and showed me how to use it. They didn't try to upsell or change the quoted price after the installation was done. Highly recommend Markham Garage Doors.

New garage door was fitted well, and it's working good. Dwight was very helpful and was able to supply a key pad for the existing opener. All the staff we interacted with were very friendly and everything proceeded efficiently. Costs were reasonable.
