Patio Door Screens in Saint-Bruno-de-Montarville

Patio doors in Saint-Bruno-de-Montarville

In Saint-Bruno-de-Montarville, the patio door on a 1960-to-1985 bungalow or cottage is rarely the one on the original plan. It was cut in later, when the owners wanted to step straight out toward the wooded lot, and it often arrived together with a wood deck, a sunroom or a solarium. That produces configurations you seldom meet in the city: a slider that opens into a sunroom rather than outdoors, a screen panel that stays shut all summer because the sunroom has screens of its own, or the opposite, a door onto a deck under the trees whose track fills with whatever drops from the branches. Each configuration wears the door in its own way, and the repair starts with knowing which one you have.

The lot changes the format too. On a big property, a wide door was sometimes chosen — three panels, or two tall ones — to open up the view toward the woods; where that is the case the screen panel follows suit: bigger, heavier, more prone to twisting when it derails. Doors added in the 1980s and 1990s are aluminum or first-generation PVC, with rollers that have to be recognized before ordering; those replaced since are current sizes. Under the trees the door sits in shade for much of the day: the mesh ages less in the sun, but the track dries poorly, and the moisture it holds feeds a paste of pollen and needles that eventually locks the roller.

What gives out on these doors in Saint-Bruno-de-Montarville

On a deck door under the trees, the track is the first culprit. Conifer needles, sticky spring pollen, dead insects and soil carried in on shoes form a deposit the roller crushes and then skids in. The roller wears a flat spot, the door jumps, someone forces it, and a large panel racks out of square far more easily than a small one. We square it up on site as long as no stile has creased, replace the rollers with the identified model, and wash the track instead of scraping it. A large panel’s mesh has a second weakness: its area. On a tall door, fibreglass stretches under its own weight over the seasons and balloons at the first breath of air crossing the deck. It is redone at the same time as the rollers, tensioned for the size of the panel.

Access and constraints in Saint-Bruno-de-Montarville

The challenge here is format and setting rather than access: bungalows and cottages are worked at ground or deck level. A three-panel or full-height door screen cannot be laid down just anywhere to be rescreened; it needs a flat, clean surface, sheltered from whatever the trees drop while the mesh is being tensioned. When the door opens into a sunroom, the space is sometimes too tight to bring the panel out on the expected side, so it comes out toward the inside of the house instead. And when the door was cut into a wall never meant for it, the outer frame may no longer be square: we measure the track and both jambs before concluding that the panel is the part that is twisted.

Which mesh for your patio door in Saint-Bruno-de-Montarville

Under the tree canopy there is little wind but plenty of shade: standard fibreglass holds up well on a sheltered door and lets the damp forest air move through. On a large panel, or a door facing an open clearing, aluminum keeps the tension fibreglass loses under its own weight. And on a big lot where the dog spends the day outside and comes back in through the patio door, pet-resistant mesh is no luxury: its thicker strand takes the pushing paw and the climbing claw where ordinary mesh gives way at the corner sooner or later.
