Window Screen Repair in Outremont

Outremont went up almost entirely between 1900 and 1940, and that era makes more trouble for a screen shop than any other on the island. The stone houses, upscale duplexes and triplexes here were built one at a time, opening by opening: two windows side by side in the same façade can differ by half an inch without anyone ever noticing. No hardware-store screen fits that, and it is not a flaw in the building — it is simply how people built before sizes were standardized. The practical consequence is direct: measurements are taken on site, window by window, and a screen made for the living room will not travel to the bedroom next door. It is also why a price quoted over the phone on this kind of housing stock means very little until someone has put a tape on the opening.

The other Outremont particularity is wood. Many owners kept their original double-hung windows instead of switching to PVC, and those windows take screens that sit between the two sashes, in a narrow rabbet. The screen frame itself is often wood as well, or thin aluminum painted to match the trim. When the mesh gives out, the first instinct is to throw the whole thing away and order a new unit — and that is almost always the wrong call. Rescreening the existing frame keeps a profile you cannot buy anywhere, keeps the window consistent with the rest of the façade, and costs a fraction of custom fabrication. On this stock, we build new only when the frame is split, warped or rotted at a corner — and in that case aluminum holds up better than fresh wood in a hundred-year-old opening, because it will not move with the seasons the way the wall around it already has.

The double-hung window dominates, and it is the type that takes the most judgement. The screen sits between the two sashes, in a rabbet that on century-old wood is no longer perfectly parallel. Mesh pulled too tight will bow the frame and make it bind; mesh left too slack leaves a gap along one side that everything walks through. It is as much a tensioning job as a measuring job. It also helps to know that on a double-hung, the screen normally covers only the operating half of the window: that is not unfinished work, it is the only way to let the sash slide up and down. When a frame has to be rebuilt, aluminum beats wood here — it stays straight in an opening that no longer quite is, and it does not swell in July humidity.

Duplexes and triplexes add a second reality: the same building has rarely been renovated all at once. It is common for a façade to still carry its original windows while the back received PVC fifteen or twenty years ago, where the view from the street did not matter. The two are not repaired the same way. Recent PVC is a common format and parts exist, which keeps the repair simple; an original opening needs measuring and sometimes fabrication. And where a balcony door has been swapped for a slider, that door is almost always the first thing to wear out its screen: slack mesh, gritty rollers, a track full of dust. We change the rollers and clean the track in the same visit as the mesh — doing one without the other just books a return trip.

The constraint in Outremont is as much aesthetic as technical. Against a period stone façade, a white aluminum frame beside dark trim reads from the street, and a badly chosen new screen spoils the look of a building that has been maintained for a century. That is one more argument for rescreening: the frame stays, the colour stays, only the mesh changes. Then there is the matter of upper floors. In a duplex or triplex, the screens of the upper units come out from inside, which means someone has to open the door — owner or tenant. That is handled by warning the occupants before the visit rather than discovering it on the sidewalk. Finally, in a divided co-ownership, a full frame or colour change is worth a look at the declaration; a straight rescreening changes nothing visible from the street.

On this stock the mesh choice is decided wall by wall rather than by neighbourhood: a shaded yard holds the evening damp, an open façade cooks the mesh. The shade and the damp that come with them favour mosquitoes at dusk, and that is where the mesh choice matters. For an upstairs bedroom, standard fibreglass is enough and lets through the most air. For a heavily planted yard or a wall that gets little sun, a tight weave also stops no-see-ums, at the cost of a little ventilation. And on a south-facing double-hung, sun is what kills the mesh before anything else: fibreglass turns brittle there within a few seasons.
