Patio Door Screens in Montréal-Ouest

Patio doors in Montréal-Ouest

In Montreal West, the patio door is always a later addition. The brick and stone houses of 1910 to 1940 opened onto the garden through a solid wood door or a glazed one with small panes; the sliding door came afterwards, in the redone kitchen, the added family room or the closed-in porch at the back. It sits in an opening cut through a masonry wall after the fact, and that opening sets its size — never a catalogue format. Because the houses are so often semi-detached, this door is almost always at the rear, facing the garden, and it is the only large ground-level opening in the house. The screen panel rolling on it is as old as the renovation, not as old as the house.

The renovation’s date changes everything. A kitchen redone in the 1970s or 1980s got an aluminum door with a narrow frame, a slender screen panel and rollers of a pattern particular to a maker now gone or renamed. A family room added more recently carries a PVC door in a common size, sometimes wide, with a heavier panel and adjustable rollers. A closed-in porch may have either, and sometimes a full screen door rather than a simple panel. In a town this small, whose street façades are this uniform, the backs of the houses are surprisingly varied, and the patio door is the best example: two semi-detached twins on the street can have, on the garden side, two doors thirty years apart.

What gives out on these doors in Montréal-Ouest

On the aluminum door of a 1970s–1980s kitchen, the roller seizes before anything else: the panel scrapes, it gets forced, and the thin frame bows at a corner. The original mesh, hardened by decades of summers, tears at the first touch. On a more recent PVC door it is more often the mesh slackening across a large panel and the height adjustment drifting, so the panel rubs on one side. In a back garden planted with mature trees, the track fills with maple keys, leaves and soil, and that mix wears rollers like sand. It is all dealt with at once — rollers identified and replaced, track emptied and lubricated, frame squared, new mesh tensioned in the existing profile.

Access and constraints in Montréal-Ouest

The door opens onto the garden, at ground level or onto a small terrace: access is easy, and it is the house that lays down the rules. An opening cut through the masonry of a 1910–1940 house is not always square, and the panel has to follow the door frame as it is, not as it should be: we measure on site. On a semi-detached house the panel does not go out by the side; it is worked in the garden or in the kitchen. And the roller on a period aluminum door is identified before it is ordered — a near match rolls crooked in a narrow track and recreates the problem we came to fix.

Which mesh for your patio door in Montréal-Ouest

A back garden sheltered by trees and a party wall does not get much wind: well-tensioned standard fibreglass suits most panels in Montreal West. Two situations change the answer. The first is a door an animal uses to reach the garden every day: the bottom of the panel, pushed at the same spot each time, calls for pet-resistant mesh. And a very wide PVC door on a recent family room, where the panel is tall and long, keeps its tension better with aluminum mesh, which does not belly in the middle over the years.
