Glass for Markham storefronts, offices and plazas
A cracked pane is a different job in a condo-owned mall unit, a Highway 7 plaza, a heritage shopfront on Main Street or an office lobby off the 404, because someone different signs off each time. Tell us the building and what happened; we connect you with an independent commercial glazier, who takes it from measuring through to a written quote and the work itself. Describe your site.
Street level
Storefronts in malls, plazas and Main Streets
Storefront glass
Cracked or smashed display glass in a mall unit, plaza row or heritage shopfront. The opening is secured first; new glass follows once made.
Windows above and behind the shop
The office window over the store or a pane in the back room. Usually only the glass needs replacing, and the frame stays.
Service and side doors
A cracked light in a rear door or the sidelight beside it. This has to be safety glass, so it's ordered to measure.
Front doors
Office entrances, closers and automatic doors
Commercial glass doors
Entrances that slam, drag, won't latch or have a cracked light. A worn closer, pivot or lock is often the cause; the door can stay.
Automatic entrances
Sliding and swing operators need someone who services that equipment. Say the door is automatic so the right pro sees it.
Offices in Markham Centre
Towers in the planned downtown, where lobby doors and suite glass are usually arranged through property management, not each tenant.
Inside the office
Interior glass for offices and tech spaces
Glass partitions
Meeting rooms, office fronts and lab walls, framed or frameless, with frosted film or switchable glass where privacy matters.
Made-to-measure pieces
Glass writing walls for meeting rooms, reception desk tops, display shelving and odd panels, each made from your measurements.
Washroom and fitness mirrors
Mirrors for staff washrooms, reception walls and fitness rooms, cut to the wall and mounted to carry their weight.
Who signs off
Strata and condo-owned units: who approves the work
In a condo-owned mall
The mall at Steeles and Kennedy is a condo corporation, so each shop has an owner. Storefront glass may be common elements needing board approval.
In a landlord-run plaza
A plaza usually has one landlord. The lease says whether the tenant or the landlord arranges glass, so read it before booking.
In an office building
Property management normally books entrance and lobby work. Tenants can still send a request; the pro works with whoever approves it.
Heritage main streets
Heritage storefronts on Main Street Markham and Unionville
Main Street Markham
Shopfronts defined by large plate-glass windows. The district plan protects that character, and a heritage permit comes before exterior changes.
Main Street Unionville
Heritage shops and restaurants in a conservation district. Shop windows, doors and lettering on the glass fall under heritage and sign rules.
The heritage grant
The City's 2026 grant can help restore authentic historic storefronts in the districts. It asks for two professional quotes, same scope.
