Patio, entry and storm doors: repair, reglaze or replace
Most door trouble in a Markham home starts with one worn part: the rollers under a grinding slider, the glass unit in a fogged garden door. Find your symptom below. We connect you with an independent local pro who handles that kind of door; they inspect, measure and quote.

Sliding patio doors
Sliding patio doors: rollers, tracks, locks and glass
Hard to slide or won't lock
Grinding, hopping the track or a latch that misses its keeper. Rollers, track caps and locks are replaced while the panel stays put.
Fog between the panes
A milky film between the panes means the edge seal has let go; it isn't dirt. The glass unit is remade to size and set into the same panel, grilles matched.
Condo balcony doors: talk to the board first
Balcony doors are usually common elements, so start with management. Replacing or altering one needs board approval and a section 98 agreement.
When the door is done
Replacing a patio door, and when the opening changes
A new door, same opening
Sliding, garden, French or tilt-and-turn. Keeping the old opening size keeps it simple; a wider opening, or a window cut down to a door, alters the wall.
Houses in the heritage districts
Exterior changes need a heritage permit, and the district plans place new doors on the rear or other inconspicuous walls of the house.
Windows at the same time
Replacing a slider beside kitchen casements? Doing both together keeps frame colour, grille pattern and sightlines consistent across the back of the house.
Front of the house
Front doors, sidelights and transoms
Entry doors
A draft at the threshold or a door that sticks. Weatherstrip and hardware come first; a full door system is the last question.
Inserts and sidelights
A cracked sidelight, fogged insert or broken patio door pane is replaced on its own, in safety glass where required.
Transoms and half-rounds
The arched or elliptical glass over a front door is made to a template. A photo of its grille pattern starts the quote.
Storms and screens
Storm and screen doors
Storm doors
Full-view or ventilating, with a closer that doesn't slam. In the heritage districts, a simple wood storm door is the style the plans encourage.
Screen doors
Sliding patio screens that jump their track, retractable screens for French doors, and hinged wood screen doors, repaired or made to fit.
Window screens
Torn mesh or a missing casement screen, rescreened in its own frame or rebuilt to size before the windows open for summer.
