Slack or torn mesh
The mesh pulls out of the spline, billows in the wind or tore at the bottom — the classic. Re-meshed in your frame, fibreglass or reinforced.

Patio door screens
Mesh, rollers, track, hardware: your screen door repaired at home in Saint-Denis-sur-Richelieu, usually in a single visit.
Three questions are enough to start. The official measurement is taken on site.
It is the most used screen in the house — opened and closed thousands of times a season. Four failures come up constantly, and all four are repaired on site.
The mesh pulls out of the spline, billows in the wind or tore at the bottom — the classic. Re-meshed in your frame, fibreglass or reinforced.
The door drags, jumps the track or scrapes. We replace the rollers and adjust the height — the most requested repair.
Sand, pet hair and debris jam the rolling. Cleaning, lubrication, light track straightening when needed.
The door no longer locks or the handle hangs loose. Hardware replaced, latch adjusted.
The core of Saint-Denis-sur-Richelieu is a 19th-century heritage ensemble, and a patio door obviously has no business on its street facade. When there is one, it is around the back: in an addition, an enlarged kitchen, an enclosed veranda or an annex opening onto the yard, out of sight from the road. For maintenance, that detail has a pleasant consequence. On front windows, every choice gets weighed against appearance; on a backyard patio door, the mesh is chosen freely for how it will be used, since nobody will see it from the road. The village constraint stops at the corner of the house, and that is good news for a door that works this hard.
Around the village, the Maskoutaine plain carries large farms whose houses have grown in stages. The patio door belongs to the last stage, often the most recent: PVC frame, common size, a sliding panel opening onto a deck that faces the fields. A door set there lives under particular conditions. The wind sweeps the plain with nothing to break it and pushes constantly on a six- or eight-foot panel; in summer that door becomes the way out to the yard and to the work outside, with all the traffic that implies. A screen panel does not age by the calendar, it ages by the number of trips through it.
What fails first is almost never the mesh, even though the mesh is what gets noticed. The rollers wear under the weight of the panel, the door drops on one side, it catches at the end of its travel, and the reflex — pushing harder — twists the frame within weeks. The mesh merely follows: it loses tension, ripples in the wind, then tears at a corner or at pet height. So the whole thing is taken back in one operation: panel out, rollers replaced and matched to the actual part when the door has a few decades on it, track cleared and lubricated, frame straightened if it has bent, mesh redone while the panel lies flat. Handle and latch are checked last, because a door restored to its proper height no longer meets its keeper in the same place.
On a farm property, the patio door is never alone: an enlarged house, sometimes an annex or a second dwelling, and other screens waiting their turn. Walking the whole property on arrival avoids a second trip for a panel nobody had seen. Access, on the other hand, works in our favour here: an open back yard gives all the room needed to lay an eight-foot panel flat during rescreening, which is far from the case everywhere. Then there is the wind, which matters at reassembly: on a wall exposed to the plain, a door that closes poorly makes itself felt with every gust, so the adjustment is finished with the door both open and closed, not just checked by eye.
Since nobody sees this door from the road, the mesh is chosen for what it does, and nothing else. Facing the fields, on a wide opening, aluminum is the one that holds its tension while the wind pushes on it all day. Standard fibreglass is enough on a door protected by a veranda or by the return wall of an addition. And if a cat or a dog goes through that door to get out to the yard, pet-resistant mesh is the only one whose strand genuinely stands up to a claw.

A patio door opens and closes more often than every window in the house combined — and it is the one the dog noses open and the cat climbs. Standard fibreglass mesh suits a lightly used door; for the others, we fit reinforced mesh, about seven times stronger, or pet-resistant mesh built for claws.
The extra cost is measured in tens of dollars; the yearly replacement it prevents, in hundreds. We carry both types in the vehicle — the decision can happen on the spot, with the door off its track in front of you.
Ten kinds of damage, one answer
If your screen looks like any of these, it can be repaired. Tap one to request a quote for that exact damage. We rarely replace a whole frame — in most cases only the mesh needs redoing.

Straight answers
Almost nothing. The work concerns the sliding panel and its hardware, not the building: the opening is not modified, neither the stone nor the brick of the old core is touched, and the door is not visible from the road. The mesh is therefore chosen for how the door is used, not for how the facade looks.
It is the tension before it is the mesh. Screening is re-tensioned during rescreening, in its own frame, with new spline; if it still ripples on a wide, exposed door, then fibreglass is too soft for that span and aluminum is the right call. We also check that the panel frame has not bent, because a twisted frame leaves the mesh slack on one side.
No, and it almost never has anything to do with the door itself. Catching at the end of travel comes from a worn roller letting the panel drop, or from the track being fouled on that particular stretch. We lift the panel out, clean the track over its full length, replace the rollers and reset the height at both ends.
Yes, at your home. We remove the screen door, replace the mesh or rollers on site, clean and lubricate the track, then reinstall it — usually in a single visit to Saint-Denis-sur-Richelieu.
Almost always the rollers: they wear out before the mesh and push the door off its track. We replace them and clean the track in the same intervention — forcing a derailing door eventually bends the frame, a costlier repair.
Rollers and hardware: from $30. A complete custom-built screen door: from $500, depending on format. The mesh alone on a door is priced on quote, from its dimensions. An exact quote is free.
One year on fabrication and installation — mesh, fitted rollers, built frames. Damage caused afterwards, by a pet or an impact, is not covered; for a dog, pet-resistant mesh is the real answer.
Pet-resistant mesh: about seven times stronger than standard fibreglass. On a patio door used daily, it is the difference between replacing the mesh yearly and being done with it for seasons.
