Markham window, door and glass services, from a fogged transom to a shop door
Home and business glass only, not windshields or phone screens. Start from the problem you can see. We aren't a glass company: we match you with an independent local pro who takes on that type of work. Can't name the problem? Send us a photo.
Start here
Start with the problem: fogged, cracked, stuck or drafty
Haze trapped between the panes
Haze that stays put when you wipe both sides is a failed edge seal. Usually the glass unit alone is replaced, not the frame.
Cracked or broken glass
A branch, a stray ball or a sash that slammed shut. Cover it for now; a new pane or sealed unit is made to measure after.
Stuck, stiff or letting in a draft
A crank that spins, a sagging hinge or a latch that won't pull the sash tight. Usually a part, not a window.
Not sure what's wrong? Send a photo
No trade words needed. A photo of the whole window and one frame corner is enough to route it to the right pro.
Windows
Window glass and window repair
Replacement windows
For frames that are rotting, warped or leaking. No City building permit is needed when the opening size stays the same, but heritage districts need a heritage permit.
Casement windows
The crank-out window. Its operator, hinges, weatherstripping and sealed unit are separate parts, and each can usually be replaced on its own.
Bay and bow windows
One fogged unit in a bay can usually be replaced on its own. A sagging seat or roof is a bigger job.
Doors & screens
Patio, entry, storm and screen doors
Sliding door that drags or won't lock
Flattened rollers, a packed track or a tired lock. Rollers and hardware can be replaced with the frame left in the wall.
Entry doors, storm doors and door glass
Fogged sidelights, a cracked insert, a failed storm door closer or a new front door. Often the glass or part changes, not the door.
Window and door screens
Torn mesh, bent frames and missing casement screens, made to size. A small job, and worth sending before mosquito season.
Glass & mirrors
Shower glass, mirrors and cut-to-size glass
Mirrors, made to measure
Custom wall mirrors, bathroom mirrors cut around outlets, LED mirrors and gym walls, with polished or bevelled edges. Measurements and a photo start it.
Shower glass doors
Swapping a dated framed or neo-angle shower for frameless glass, or replacing a sweep, hinge or seal on the one you have.
Custom glass
Tabletop protectors, cabinet panes and glass shelves cut to size. Send measurements or a photo of the broken piece to start.
Commercial
Offices, plazas and storefronts
Storefront glass
Shop windows that are cracked or clouded, boarded or taped first and reglazed later. In a condo-owned mall, the corporation may need to approve the work.
Commercial glass doors
Lobby and plaza doors that drag, slam or won't lock: closers, pivots, hinges and the glass itself, repaired or replaced.
Office glass partitions
Glass walls and interior glass doors for Markham's head offices and tech firms, from one meeting room to a floor.
Specialist work
Heritage homes and shaped glass need a specialist: here's where to start
Heritage permit and grant
In Unionville, Markham Village, Thornhill and Buttonville, window changes need a heritage permit first. The guide covers the rules and the 2026 grant.
Original wood sash
The district plans ask that original frames and sash be repaired rather than replaced, and Markham Village's plan asks for original glass to be reused.
Arched, transom and foyer glass
Half-rounds, eyebrows, transoms and two-storey foyer units need a custom sealed unit, matched grilles and sometimes a lift. The frame often stays.
Part or whole
Is it the part, or the whole window?
A part or a new unit is usually enough when
- Only the half-round or one casement has fogged
- The operator strips, but the sash closes tight by hand
- A slider drags on worn rollers, not a bent frame
A whole window or door earns its place when
- Water has stained the drywall below the sill
- Units are clouding along a whole side of the house
- You want a builder-grade slider changed to a casement

Finding the right service
Service areas
Markham and nearby York Region
Requests go to pros who cover that address. At the edges of the area, we check before promising anyone.
Can't tell which one it is?
A photo of the whole window and one frame corner often says more than a service name. Send it and we'll work out who should see it.
