Montreal patio doors — big light, no draft

A quality sliding patio door is the easy indoor-outdoor connection: it glides open with one hand, locks securely, and — when it is built and installed right — seals against drafts as well as a good window. We install insulated units with efficient Low-E glass and quality rollers so the big expanse of glass keeps the room warm through Montreal winters instead of turning into a cold wall by the couch.

Because it slides rather than swings, a patio door is the space-saver — nothing projects into the room or onto the deck — which makes it ideal where furniture or a tight deck would block a swing. For a wall-wide opening, step up to a sliding glass door.

Prefer a door that opens wide with a more traditional look? See French doors, or the space-saving garden door in between.

Set dead level to glide and seal tight

We set the door dead level and plumb so it glides smoothly for years — a slider that is out of level binds and wears its rollers fast — then seal and insulate the frame against the cold and adjust the rollers and multi-point lock so it slides easily and latches tight.

The written quote covers the door, the glass package and the install, all backed by warranty. Compare a swing-open French door, a compact garden door, or the full door lineup before you decide.

Winter cold, sliding-versus-French and secure locking.

Are sliding patio doors cold in winter?

Not when it is insulated with efficient glass and sealed properly. The old aluminum-framed sliders earned patio doors a cold reputation, but a modern unit with a thermally sound frame, triple-pane Low-E glass and a tight perimeter seal keeps a big glass door comfortable even on a deep-cold night. The keys are the glass package and the install — a well-sealed frame and a door set level so it closes tight. We spec and install units built for our climate, so you get the light and the view without the cold draft.

Sliding or French patio door?

Sliders save space and maximize the glass, since nothing swings into the room or onto the deck — ideal for tight spots and the biggest possible view. French doors swing open wide for a classic look and a full, unobstructed opening, but they need clear swing space inside or out. A garden door splits the difference with one swinging panel and one fixed. We help you weigh space, style and budget at the measure and pick the door that fits your opening and how you will use it.

Do patio doors lock securely?

Yes — modern patio doors come with secure multi-point locking that engages the door into the frame at several points, not just a single latch, which makes them far harder to force than the old single-lock sliders. We can also add a secondary foot-bolt or a security bar and anti-lift hardware for extra peace of mind, and set the lock so it engages smoothly every time. Combined with laminated or tempered glass options, a properly installed patio door is both secure and easy to operate.

Can I get a built-in blind or screen with a patio door?

Yes — many patio doors offer integrated blinds between the glass and sliding screens; we go through the options at the measure.

How much clearance does a sliding patio door need?

A slider needs no swing space, only the track width, which is why it suits tight rooms and decks where a swing door would not fit.

New sliding patio door glides with one finger and seals tight. The efficient glass keeps the room warm even by the door.

Big bright slider to the deck, set dead level so it rolls smoothly. Secure multi-point lock too.

No more cold air off the old patio door. Quality rollers and a proper seal make a real difference.
