Markham Garage Doors is a very professional contractor. Brandon (now managing Whitby Garage Doors) gave me a tour of their Markham immaculate showroom which was well stocked with samples of the products that they install. He asked me about my plans, showed me a range of options and then gave me some brochures (with notations) so that I could take my time making my final selection. When I made my selection I phoned Kevin Chappel (the owner), who came to my home, gave me a written estimate and explain how the installation could proceed. Before I signed the contract, he gave me a probable installation date. One day prior to the proposed date, he phoned me to tell me that the components had arrived and checked that the following day was still convenient to the installation. As scheduled, John did the installation the following day and made certain that I was familiar with the operation of the garage door. He removed the old door and its components and left the area spotless. The following week, Robert arrived, as scheduled, to do the aluminium capping around the door and again left the area spotless. Great service, great product, great people!
