Montreal window weatherstripping that stops the draft

Feel a draft or hear a whistle around a closed window? The weatherstripping — the foam, bulb, fin or pile seal between sash and frame — has hardened, cracked or flattened after years of Montreal winters.

Every opening measured on-site

Full air-seal on every unit

Written frame + sealed-glass warranty

Stop the draft at the seal

Weatherstripping is the compressible seal — foam, bulb, fin or pile — that closes the gap between sash and frame when a window shuts. It keeps the cold out, and it is a wear part: over years of Montreal temperature swings it hardens, cracks, flattens or peels away, and cold air pours in around a window that otherwise looks fine.

Fresh seals are one of the cheapest comfort upgrades there is — a small material and labour cost against a noticeable cut in draft across a whole house, far less than energy-efficient replacement.

We match the seal profile to your window and fit it so the sash closes airtight. Bundle it with hardware repair, window caulking or a free draft check.

Airtight and warmer

New seals cut drafts, lower heating costs and reduce outside noise — a fast, affordable fix that brings an older but sound window back to comfortable service without the cost of replacement.

We match the bulb, fin or pile profile to your window so it compresses and seals evenly, and check the sash fit while we are there, since a seal only works if the sash closes tight. Explore related window repair work, from foggy unit repair to glass repair.

Montreal window weatherstripping, answered

Spotting worn seals, heating bills and old-window value.

How do I know if my weatherstripping is worn?

The clearest signs are a draft you can feel near a closed window on a cold or windy day, a whistle at the sash, or visible daylight, gaps or flattened, cracked, brittle stripping around the sash. You might also notice more condensation or a room that never quite warms up. Any of those means the seal has hardened or worn and is no longer closing the gap between sash and frame. It is easy to check at the visit, and replacing worn weatherstripping is a quick, low-cost way to stop the draft.

Will new weatherstripping lower my heating bill?

It helps — sealing the drafts around your windows reduces the heated air leaking out and the cold air sneaking in, which eases the load on your heating system, and the effect adds up across a whole home full of windows. It will not fix a house with single-pane glass on its own, since the glass itself also loses heat, but as part of tightening up the envelope it is one of the best dollar-for-dollar improvements you can make. On a sound window with good glass, fresh weatherstripping is a cheap, effective comfort and efficiency boost.

Is it worth it on an old window?

If the window and its glass are otherwise fine and only the seal has worn, yes — replacing the weatherstripping is a low-cost way to restore comfort and stop the draft without spending on a new window. It is one of the first things we check on a drafty but structurally sound window. If, on the other hand, the frame is rotted, the glass is single-pane or fogged, or the sash no longer closes square, new weatherstripping alone will not fix it, and we will show you the replacement numbers so you can weigh the better long-term value.

How long does new weatherstripping last?

Quality weatherstripping lasts many years; how long depends on use and exposure, and we match the right profile to your window so it seals evenly.

Can you weatherstrip any type of window?

Most operating windows can be re-sealed — we match the bulb, fin or pile profile to your unit so the sash closes tight again.

Felt a draft at a closed window every winter. Fresh weatherstripping matched to the window and it seals tight now.

H. Robidoux

Homeowner, Montreal

Cheapest fix that made the biggest difference. Less draft, less noise and a warmer room.

A. Sohi

Homeowner, Laval

They checked the sash fit too, since the seal only works if the window closes right. Thorough and honest.

J. Boucher

Homeowner, Longueuil

Quick job that stopped the cold air coming in around the sash. Should have done it years ago.
