Window Screen Repair in Greenfield Park

Greenfield Park did not start out as a suburb. It was a summer village next to the railway, and it was the post-war years that filled it in: small brick cottages and bungalows built between 1945 and 1965, on streets whose trees have had decades to grow. Now part of Longueuil, it borders Saint-Lambert, Saint-Hubert and Brossard, where our van is based. For screen work, what matters here comes down to one sentence: almost none of these houses still has only its original openings. Verandas were closed in, then patio doors were cut in during later renovations. A single address often carries three generations of screens — the ones from the original house, the ones from the enclosed veranda, and the patio door screen — each with its own hardware, its own way of being held, and its own dimensions. The job starts by telling them apart, not by pulling out a tape.

Enclosed verandas are the local feature most worth knowing about. When a veranda is screened, it is rarely a single unit: it is a run of panels, built the same year, facing the same sun and the same wind. They therefore fail together, or within a few months of each other. One panel tears first, but it is rarely the only one near the end of its life, and that is what gets expensive — redoing every worn panel in one visit costs far less than a separate trip for each one. They are also the easiest units to handle: they lift out, get worked flat on trestles, and go back in. On a veranda in full sun, aluminum mesh holds the plane of a large panel better; fibreglass is softer and will ripple in the heat at those sizes.

The original openings on these cottages and bungalows are small and numerous, and their screens often sit in narrow aluminum frames no retailer stocks any more. That is the situation that makes the strongest case for rescreening: the frame is still straight, only the mesh has gone, and putting new mesh in the existing frame costs far less than having a new frame built to a size that no longer exists in any catalogue. On horizontal sliders we check the rollers and the track at the same time: a panel that gets forced because it binds ends up bowed, and a bowed frame will not hold new mesh for long. Double-hung windows, fewer here, take a screen fitted between the two sashes, where aluminum behaves better than fibreglass.

The patio door is the most requested repair, and in this neighbourhood it was almost always added after the fact, in an opening cut into an existing wall. Its width is not necessarily a commercial width, and the screen that came with it was made for that door. We repair it rather than replace it: square the frame, new rollers, track cleaned and lubricated, then mesh. Under mature trees the track is the weak point — leaves, maple keys and winter road sand collect in it and wear the rollers out long before the mesh is finished. Cleaning the track is part of the repair, not homework left with the owner. A door that slides easily lasts years longer, because people stop pushing it by the mesh.

Nothing here is a catalogue size, and that is why a stock-size panel from a hardware store almost never fits these openings. The panels of an enclosed veranda were built for that veranda, often on site, to dimensions that exist nowhere else. The patio door was fitted into an opening cut long after the house went up. And the original 1945-1965 screens use narrow aluminum extrusions that are no longer sold. Three families of parts, none of them standard. The answer is not to replace everything: it is to measure each unit on site, put new mesh into the existing frame wherever that frame is still straight, and build custom only what has no salvageable frame left.

The neighbourhood's tree-lined streets change how screens wear. Less direct sun on the mesh means standard fibreglass ages well here and is enough in most cases. What does cause trouble is everything that falls from mature trees — leaves, maple keys, small branches — collecting in patio door tracks and along the bottom of veranda panels. It is a hardware problem before it is a mesh problem. Two exceptions: large veranda panels, where aluminum holds its plane better, and households with a cat, where pet-resistant mesh saves redoing the patio door screen every year.
