Patio Door Screens in Côte-Saint-Luc

Patio doors in Côte-Saint-Luc

In the apartment blocks and high-rises of Côte-Saint-Luc, built between 1960 and 1975, the patio door is not a garden door: it is the balcony door, and often the only full-height opening in the unit. It was installed in series, one model per building, in narrow-profile aluminum with a screen panel in the same metal that is now half a century old. An aluminum panel of that generation does not rot: even after years out of service, it goes back to work as soon as its hardware is redone. Two panels in the same building come from the same profile: when one glides and the other jams, it is the roller, not the size, that makes the difference.

Around the towers, the streets of post-war bungalows and duplexes tell a different patio-door story. On the bungalows it is sometimes original, in aluminum, at the back of the dining room; more often it was added in the 1970s or 1980s in place of a window or a kitchen door, to open onto the yard. In the duplexes, the upper unit’s patio door opens onto a rear balcony and the lower one onto the lot. These doors have served a long time, and their screen panel, where it still exists, has brittle mesh and flat-spotted rollers. Côte-Saint-Luc is largely English-speaking; the diagnosis and the explanations are given in English or French, whichever the owner or tenant prefers.

What gives out on these doors in Côte-Saint-Luc

The balcony door of a 1960s tower suffers from three things: its rollers, with decades of service behind them; its track, where fine city dust settles and packs down with the rain; and its panel, which takes wind at height in a way no window in the unit does. When the rollers seize, the panel gets forced, and a narrow aluminum frame twists quickly. We identify the building’s roller model, replace it, scrape the track clean, straighten the frame and tension new mesh — all of it inside the unit, with the panel lying on the floor. On the bungalows and duplexes the scenario is the same with easier access; what changes is that a door added in the 1980s sometimes has a panel in a size no longer made, which we rebuild to the track’s dimensions.

Access and constraints in Côte-Saint-Luc

On a patio door here, what decides the job is who owns the door: in a rental building, it is part of the building. In these buildings the panel is always brought in through the unit, and that is what makes the floor irrelevant: the whole job happens on the floor of the apartment. The work happens on the floor, inside the unit, and the panel goes back into its track from indoors. Many of these apartments are rented: the patio door belongs to the building, and who authorizes and who pays is settled between tenant and property manager before the visit. When the frame has to be rebuilt entirely, it is built to measurements taken in the unit and assembled on site — a full-height panel does not always fit in the elevator of a 1965 building.

Which mesh for your patio door in Côte-Saint-Luc

At height the choice is quick: a tower’s balcony door takes gusts that no window in the same unit ever sees, and soft fibreglass stretches loose there in a season or two before slipping out of its groove. Aluminum mesh, stiffer, holds its tension across that large panel. If a pet has access to that door, pet-resistant mesh is the only choice that lasts in a unit where it is the only full-height opening. At ground level, in the bungalow yards and behind the duplexes, standard fibreglass remains the best balance of light and airflow.
