Window Screen Repair in Montréal-Nord

Montréal-Nord is a Montréal borough built almost all at once: brick duplexes, triplexes and small apartment buildings put up between 1950 and 1970, tightly packed, with balconies and outside staircases. That construction date is the single most useful fact for anyone repairing screens here, because it decides the window type. The early-century plex closer to the centre of the island is a double-hung story; the postwar north end was glazed with sliders. And a slider does not wear the same way at all. Its screen doesn't rest in a vertical track — it rolls sideways on rollers that take all the load. The result, in this stock, is that a screen that no longer works has a hardware problem far more often than a mesh problem.

The other trait is density: a borough of small apartment buildings, so plenty of owners who don't have one window to fix but six, eight or twelve identical units in the same building. Screens in a 1950-1970 building went in on the same day, faced the same sun and were worked through the same number of summers: when the first gives out, the others follow within a season or two. That changes how the work should be approached. Rather than repairing one at a time, it is better to inventory the building — floor by floor, unit by unit — and handle everything that is ripe at once. One detail worth knowing: despite looking identical, screens in the same building don't always share exactly the same dimensions, and each one gets measured.

On a sliding window, the screen rolls on a track, outside or inside depending on the model, and comes off by lifting it and clearing the bottom. The rollers fail first: once flattened, they drop the frame into the track, the screen catches, you push harder, and the aluminum frame ends up out of true. At that point most people assume the screen is finished. It almost never is. The rollers get replaced, the track gets cleaned — on a busy street it fills with sand, dust and winter grit — and the frame gets straightened. The mesh is redone in that same frame when it is torn or slack. On original units from 1950 to 1975 the profiles are narrow and no longer sold: keeping the frame isn't only cheaper, it is often the only way to keep the right size.

Balconies, everywhere in this kind of building, add a second family: the sliding and patio doors that open onto the rear balcony. It is the most frequent repair in the trade, here as elsewhere, but use makes it worse — a balcony door worked by a whole household several times a day, six months a year, flattens its rollers quickly and goes slack at hand height, exactly where people push. All of it is handled on site. Finally there are the basement and stairwell screens, usually left off a building's inventory and yet the first to get punctured, because they sit within reach of the street and the lane.

The constraint specific to Montréal-Nord is neither height nor size: it is coordination. Most slider screens come off from inside the apartment, so a building owner cannot have tenants' units done without notice and arranged access. A visit that finds half the doors closed turns into a second visit. An inventory taken beforehand solves much of it: unit number, floor, how many screens per apartment, and what is actually wrong with each — broken, or merely dirty and off its track. Street parking and outside staircases account for the rest: in a dense borough, time is lost between apartments, not at the window.

Montréal-Nord is bordered to the north by the Rivière des Prairies, and a body of water changes insect pressure in the evening — precisely when balconies get used. That is the main argument for mesh in genuinely good shape rather than mesh that is still passable: a two-centimetre tear in one corner cancels out the rest. For a sliding window left open all summer, standard fibreglass is enough in most cases; if a cat regularly climbs the balcony screen, pet-resistant mesh is the only format that lasts a full season. On a building facing a busy street, a track cleaned every spring extends the life of the rollers as much as the mesh.
