Window Screen Repair in L'Île-Dorval

L’Île-Dorval is reached by ferry, and that single fact shapes everything else. It is a small island in Lac Saint-Louis, within the Montreal agglomeration, next to Dorval, Pointe-Claire and Lachine. What stands on it is essentially wooden summer cottages with verandas and galleries, with no significant permanent population. This isn’t a suburb — it’s a cluster of seasonal buildings, opened in spring and closed in the fall, whose screens work six months a year and sit idle for the rest. A year-round house lives with its windows daily and sees trouble coming; a cottage reveals everything at once, on opening day — mesh pulled loose, a frame warped over the winter, a punctured veranda panel. That is why the sensible time to go through the screens here is at the start of the season, before the veranda gets used.

The other defining factor is exposure. The island is surrounded by the lake: steady wind, high humidity, spray. On wood, that shows up in the frames — the wood swells, dries and swells again, and the small tacks or staples holding the mesh eventually let go one corner at a time. On the mesh, lake humidity and sun age fibreglass faster than in a sheltered neighbourhood: it whitens, hardens, and tears the first time a hand presses on it. A large veranda panel is always the first to show it, because the surface is big, the mesh spans a long distance, and the wind pushes on it like a sail. A stiffer mesh holds its tension there far better than a light fibreglass.

Verandas and enclosed galleries are what makes the building stock here distinct, and they don’t repair like a window. They are large panels, usually in wood frames fixed to the structure, sometimes built in sections between posts. The mesh spans much further than it would in a window, so it stretches sooner and takes badly to repeated pressure — a chair back, a dog, a branch. On those surfaces, aluminum mesh is often the better choice: stiffer, it keeps its shape and doesn’t develop the slack pocket in the middle that shows up on large fibreglass panels. Restoration is done panel by panel, redoing the tension and the fastening at the same time as the mesh.

The cottages themselves usually carry older windows — double-hung or casement depending on the age of the building — and often screens originally made for that exact opening. On a double-hung, the screen sits between the two sashes and covers the operating half; an aluminum frame ages better there than wood. On a casement, the screen is interior and comes off its latches, which makes it easy to rescreen in its own frame. In both cases, a wooden building moves with the seasons and the openings stop being perfectly square: measurements are taken on site, on the real opening, and custom fabrication takes over when the original frame is gone or beyond saving.

Access is the real constraint, and it is planned rather than improvised. An island served by ferry isn’t visited like a suburban street: there’s no quick trip back to the truck for a forgotten part, and a return run for one missing roller depends on the ferry schedule. The sensible way to work is to group everything: go through the whole property at once, note every veranda panel and every window, and settle the meshes for the entire place, rather than calling about one screen at a time. It is also why dimensions are taken on site and never over the phone — on an older wooden building, half an inch of error measured from a distance means a panel to redo, and redoing one here is not a simple second visit.

On the lakeshore, insect pressure is real and it decides the mesh. No-see-ums and black flies pass straight through standard fibreglass; only a tight weave stops them, and that’s the logical choice for a veranda used on summer evenings. Wind and lake humidity argue for aluminum on the large panels, which keeps its tension where a soft mesh ripples. The two combine on one property: tight weave where people sit, aluminum where the panel is large and exposed. The working season runs April through October.
