Patio Door Screens in Dorval

Patio doors in Dorval

Dorval has two ages, and neither was built with a patio door. North of the railway, the bungalows and cottages of the 1950s and 1960s opened onto the yard through a hinged door or a window; the sliding door came later, cut into an existing wall during a kitchen renovation or an addition. These retrofitted doors are therefore not as old as the house, but they have no guaranteed size either: the opening was cut to fit whatever was available at the time, sometimes a narrower or shorter door than today’s common dimensions. The screen panel that closes it is cut to the same measure, and nothing off the shelf replaces it as is.

Along Lac Saint-Louis, the houses inherited from the resort era live differently. Where a patio door was added, it often opens onto the screened veranda or the sunroom rather than onto the lawn: the sliding screen then closes the passage between the house and a room that is already protected, and serves mostly as a night door or a shoulder-season door. Where the door faces the grounds directly, it takes the wind off the lake head-on, over its full height. Those are two opposite wear patterns — the first wears the hardware through back-and-forth, the second tires the mesh through pressure — and they are not solved with the same materials.

What gives out on these doors in Dorval

On a patio door installed in a 1950s house, the track was rarely set on a sill made for it: it sits on fill, and it eventually sags to one side. The screen panel then rolls on a slope, the rollers wear unevenly and the latch no longer meets its keeper. Putting that right means setting the rollers to different heights to compensate, or reworking the track when the slope is too steep. On the waterfront doors, fibreglass mesh gives out at the bottom first, where wind pressure pushes it out of its groove; the spline, dried out, no longer holds. It is replaced together with the mesh, and the rollers are changed in the same visit: a door that rolls badly twists again by the first summer.

Access and constraints in Dorval

A Dorval patio door raises the question of its size before anything else. A patio door retrofitted into a 1950s bungalow can be five feet wide where the market makes six, and its clear height depends on the header installed at the time. So we never order a panel on a nominal size: we take the width of the track, the height between the track and the top guide, and the closing gap against the jamb. On the lake side, verandas add an access constraint: the patio door opens inside a screened room, and sometimes the veranda has to be cleared or one of its panels unhooked to get the screen out flat. A frame twisted to squeeze it through is no longer a frame worth rescreening.

Which mesh for your patio door in Dorval

Facing the lake, the question is wind before insects. On a patio door that opens straight onto the grounds, with no veranda in front, aluminum mesh stays flat under pressure and does not hollow in the middle; it is the choice that lasts. On a door that opens into an already screened veranda, sheltered, standard fibreglass is more than enough. In the bungalows to the north, the question becomes pets: a dog waiting at the door in the evening ends up putting its paws on it, and pet-resistant mesh spares you the same tear every year.
