Window Screen Repair in Mont-Royal

Mont-Royal was drawn before it was built. The garden city planned from 1912 produced a town of rare consistency: single-family brick houses from the 1920s through the 1950s, English cottage or Tudor in style, set along curved, planted streets. For screen repair that consistency has one direct consequence — the windows resemble each other from house to house, but nearly all of them belong to a generation that no longer exists in stores. You find casements and divided-light double-hungs, with original screens mounted in narrow frames of wood or thin aluminum, in sizes that were never standardized. On these houses the question is not which model to buy, because there isn't one. It is whether the existing frame is still straight. If it is, putting new mesh in it is both the simplest fix and the one that leaves the façade alone.

Alongside that original stock, the town has recent high-end rebuilds, sometimes right next door to a 1930 cottage. Those houses play a different game: large openings, generously sized casements, patio doors and occasionally window walls whose screens, where they exist, are bigger and heavier than anything on a period house. The work changes character. On a large casement or patio screen, mesh tension and frame rigidity are what matter: mesh left too slack on a big span ripples in the wind and works its way out of the spline groove. A partial renovation often leaves both situations in the same house — period screens to save upstairs, oversized recent ones to re-tension on the main floor.

The casement is the window that surprises new owners most: its screen is on the inside, not outside. It comes off with two or four latches, from within the room, and that is exactly what makes the job straightforward — unclip it, pull the spline, stretch new mesh, put it back, no ladder and nothing touched on the window itself. The divided-light double-hung of the 1920s to 1950s works differently: the screen sits between the two sashes and covers only the operating portion, usually the lower half. Many owners think theirs is incomplete or badly fitted; it is normal. On that format an aluminum frame beats a wooden one — it stays straight in its track year after year, and the upper panes stay visible from the street because the screen only covers the bottom.

On recent rebuilds and rear additions, the patio door takes over and concentrates the wear. Its screen slides every day on rollers that flatten long before the mesh fails: the door catches, you push, the frame goes out of true and eventually jumps the track. Cleaning the track, replacing the rollers and re-tensioning the mesh settles the large majority of these, on site. Big casement screens fail differently: the mesh goes slack in the middle, forms a pocket and lets go at one corner. There, re-tensioning properly in the existing frame beats replacing it, provided the aluminum hasn't been bent. A frame that is merely out of true can often be straightened; one broken at the mitre cannot.

Mont-Royal's difficulty is as much visual as technical. In a town laid out from a single plan the façades answer each other, and one new screen in a slightly different white, or in a wider frame than its neighbours, is noticeable from the street. That is the strongest argument for rescreening on period houses: keeping the original frame keeps the line of the window. The other difficulty is supply. The narrow frame profiles used on screens from the 1920s to the 1950s are no longer carried by retailers, and a house of that era rarely has two identical openings. When a frame really is beyond saving, the replacement is built to measurements taken at the window, opening by opening — never to a catalogue size.

A garden city planted more than a century ago has big trees, and that changes the mesh you want. Mont-Royal's shaded streets hold humidity: mesh dries more slowly there, soils faster and goes slack sooner. For a casement left open all summer under trees, a good-quality fibreglass mesh is enough in most cases. If a cat goes out through the patio door, or climbs the living-room screen, pet-resistant mesh is the only choice that lasts more than one season — claws go through ordinary mesh in the first year.
