Window Screen Repair in Côte-des-Neiges–Notre-Dame-de-Grâce

Côte-des-Neiges–Notre-Dame-de-Grâce ranks among Montréal's most populous boroughs, and its housing stock reads like three cities stacked on top of one another. The foundation is the brick duplexes and triplexes built between 1910 and 1940, with their outdoor staircases and their sash windows. A century later those buildings are still standing and still lived in, but their screens have been redone, replaced, patched or lost over the decades. On a single facade, the panels can therefore belong to three different generations. The good news is that the sash window lends itself well to repair: its screen is a simple panel, often half-height, that slides between the two sashes and lifts out without dismantling anything.

To the west, Notre-Dame-de-Grâce has its streets of English-style cottages, where no two houses share the same openings: bay windows, paired windows, arched openings, sizes decided when the house was built rather than by a catalogue. There, measuring on site is not a formality — it is the only way to end up with a screen that actually closes. To the north, Côte-des-Neiges is dominated by large post-war apartment towers, whose windows carry their screen inside the unit. Three kinds of building, three repair logics: the sash panel to rescreen, the cottage's custom-built screen, and the apartment frame that unclips from latches. One borough, but nothing in common from one sector to the next.

The sash window is the signature of the borough's pre-war housing, and it is also the one people understand least. Its screen does not sit in front of the window: it slides between the two sashes, in the operating half, which puts it in constant contact with the sash that travels up and down. That friction wears the mesh along the edges long before it fails in the middle. Standard fibreglass frays there; aluminum mesh, being stiffer, takes the back-and-forth better and holds its shape in a panel that was rarely built to be rigid in the first place. When the frame has bowed or its corners have shifted, it gets straightened before rescreening — fresh mesh stretched into a twisted frame comes out twisted.

In the Notre-Dame-de-Grâce cottages the question changes. The openings are large, not always square, and the original panel has often been gone for years. That means building new, frame included, to measurements taken on site. A living-room bay can call for a panel considerably wider than anything sold off the shelf, and that is exactly what a hardware store does not carry. In the Côte-des-Neiges towers, by contrast, everything is standardized and the screen comes out from inside on its latches: the work happens in the unit, no ladder, whatever the floor. One call can therefore cover a triplex, a cottage and an apartment — but those are three different jobs.

Access is the real constraint here. In a triplex, the upper flat is reached by the outdoor staircase, and a second- or third-floor sash screen cannot be taken down from the sidewalk: it comes out from inside, through the window itself, which means someone has to be there to open up. When the flat is rented, that gets arranged between owner and tenant before the visit, not on the landing. Second point: in a multi-unit building, it is worth walking every window at once rather than coming back. You leave with the full list — panels to rescreen, missing panels to rebuild, hardware to replace — and the work gets done in a single visit instead of three trips.

The borough sits well away from open water, so no-see-ums and black flies are not the main issue. It is ordinary mosquitoes from June through August, on back balconies and in interior courtyards, plus the urban dust that loads the mesh year after year until it goes nearly opaque. On south-facing walls, fibreglass hardens and cracks faster than elsewhere. An indoor cat often decides the choice on its own: on a balcony screen or a low window, pet-resistant mesh stands up to claws where standard mesh gives way far sooner. The working period runs April through October.
