Markham Glass & Door Repair and Installation

Markham’s mix of offices, plazas, and townhomes calls for careful sequencing. In Downtown Markham, along Highway 7, and across Unionville Main Street, DoorWin Services combines rapid protection (board-ups, cleanup) with measured final installs — storefront glazing, door-lite replacements, sealed units, and exit device upgrades that keep entries looking sharp and operating safely.

We coordinate off-hours access around Warden, Kennedy, Woodbine, and Markham Road so retailers stay open while we service entrances: hinges and pivots set, closers balanced, locks aligned, access control and automatic doors tuned to code. When security is a priority, we provide laminated safety glazing and professionally installed security film.

For homes in Cornell, Berczy, Cachet, and Greensborough, we replace fogged IGUs and complete window systems, rebuild patio sliders with new rollers and track work, and apply clean exterior sealing that stops drafts without messy lines. Frameless partitions, mirrors, and shower glass bring clarity indoors. Expect tidy protection of finishes, dust control, proper disposal, and a documented handoff with photos and warranty details.
