Galleries & porches
Screened porches and balconies: rescreening and new panels
A screened gallery turns a plex balcony into a summer room, until the mesh sags, tears or blows loose. Usually the frames can stay and only the mesh is replaced, panel by panel. Where frames have rotted, new panels are made to the openings. We connect you with an independent local pro who rescreens galleries and porches and builds new screen panels to size.

Plex galleries
Galleries and balconies on a plex
Montreal plexes are known for their outside staircases and back lanes, and many flats have a gallery behind and a balcony in front. Screened-in panels there are big, exposed on every side, and the ones by the stairs get knocked by everything carried up and down. Houses farther out have their own version: a screened porch like the one pictured, or a gazebo.
Rescreening
Rescreening existing panels
If the frames are sound, each panel gets new mesh and spline, in place or taken down, depending on how it was built. Wood frames are checked for soft spots where the mesh is stapled under trim; aluminum ones for bent sections. Only damaged panels need doing, though redoing a whole side keeps the mesh matched. Heavier mesh suits low panels a dog leans on.
New panels
New panels made to measure
Where frames have rotted or a gallery has never been screened, the pro measures each opening and builds panels to fit. Openings on older galleries are seldom identical, so every one is measured. Before enclosing a gallery for the first time, check with your borough, since each runs its own counter and rules; our guide to borough permits explains how those counters work for doors and windows.
Balcony work
Rebuilding the balcony? Coordinate the work
If the balcony or its guardrail is due to be rebuilt, wait for the new structure, then measure. Panels made for old posts won't fit new ones. For eligible small plexes on the island, the City's RénoPlex program can help pay for rebuilding a balcony or replacing a guardrail, if approval comes before the work. It funds the balcony, not the screens. See the amounts by type of work and our RénoPlex guide. Glass guards are a separate job: see glass railings.

Condos
Condo balconies: common portions and the syndicate
In a condo, the balcony you use may not be yours alone to change. Whether it counts as a common portion, and who decides what goes on it, depends on your declaration of co-ownership, so read it and ask the syndicate before ordering panels. For window and door replacements, the City already asks co-ownership buildings for each co-owner's letter or a syndicate resolution (montreal.ca). Our page for condo syndicates and owners covers the wider process.
The way in
Gallery screen doors
The gallery's screen door works harder than any panel. It can be rescreened with the rest or replaced if twisted; closers and hinges are covered on the screen door page. For the door between the flat and the gallery, see plex balcony doors.
