Window Screen Repair in Montréal-Ouest

Montréal-Ouest fits into a handful of streets, but its housing raises one of the most demanding screen problems on the island: nothing here is a standard size. It is an early twentieth-century garden suburb, built of brick and stone between 1910 and 1940, often semi-detached, with original wooden double-hung windows in dimensions that match no product sold today. On a house of that period it is common for two neighbouring windows on the same wall to differ by a few millimetres — enough that a store-bought screen fits neither. The practical consequence is simple: here a screen isn't bought, it is rebuilt or built, and always from measurements taken at the window itself.

The original wood adds its own logic. A wooden sash and a wooden screen frame that have spent more than eighty years outdoors don't fail all at once: they come apart at the corners, the groove that holds the spline gets crushed, and the wood swells in summer and binds in its track. Many of these frames are still perfectly sound along their lengths and need only to be reglued, squared up and rescreened. When the wood is split too far to hold mesh, custom fabrication takes over, with a new frame cut to the dimensions actually recorded — not to assumed ones. The fact that many houses are semi-detached matters too: a party wall removes an entire elevation, so the openings concentrate at the front, the back and along one side, often a narrow passage.

The wooden double-hung is the dominant window and it has its rules. The screen sits between the two sashes and covers only the operating portion, nearly always the lower half: that is not a half-product, it is the original arrangement, and it leaves the upper panes visible. The period frame is thin, wood or very narrow aluminum, and it is fitted to an opening that is its own. Three faults recur on this format: mesh torn along one side because the spline came out of its groove, a frame that has lost square at one corner, and swollen wood binding in the track. All three can be corrected without replacing the unit — provided the frame is dealt with before new mesh goes in. Rescreening a twisted frame only stretches the fault tight.

At the back of the house the picture changes. Kitchens and sunrooms on 1910-1940 houses were often redone later, so you find sliding doors, patio doors and storm doors with screen inserts, all from different eras than the rest of the house. On those, the wear is in the hardware: flattened rollers, a track packed with soil, a storm-door insert dropped out of its clips. They are handled on site, without touching the original building fabric. If there is a gazebo or a screened porch in the yard, its panels and clear MICA film are the same kind of work, on larger spans where mesh tension matters more than mesh type. A single house can hold three generations of screens, each repaired on its own logic.

The real challenge here is resisting the pull of standard sizes. In front of 1910-1940 windows, every opening has its own dimensions and sometimes its own angles, and a frame ordered on an approximate measurement comes back too big or too small — enough that it won't sit. Measurements are therefore taken at each window, one at a time, which is also why no firm quote can honestly be given over the phone on this kind of house. The second obstacle is physical: on a semi-detached, side access is often a narrow passage between two houses, not a comfortable place to work. Fortunately the double-hung comes apart from inside: the work happens in the room, not in the passage.

A garden suburb more than a century old has mature trees, and the damp shade they cast is hard on mesh: it dries slowly, loads up with pollen and dust, and goes slack sooner than it would on a sunny elevation. Mature trees also bring squirrels and cats onto sills and door screens: ordinary fibreglass tears under repeated clawing, where pet-resistant mesh holds. For the upper double-hungs, which get worked far less, standard fibreglass remains the normal choice — and an aluminum frame slides better than a swollen wooden one.
