Ahuntsic and Cartierville: replacing to match the original
In Ahuntsic-Cartierville, a new window has to look like the one it replaces. The borough asks for the same form and appearance, and the same typology: the opening type, the divisions and the colour. For many owners that makes the smaller job the easier one. A new thermos, the sealed glass unit Quebeckers call by that name, or a repaired crank leaves the window exactly as the borough wants it. We're a free referral service that connects you with an independent glass professional who works in the north end; that pro measures, quotes and does the work.

Former villages that became neighbourhoods
Ahuntsic was founded as a village in 1897 and joined Montréal in 1910. Cartierville grew once it became the end of the line for the 17-Cartierville tram in 1898, and it was annexed in 1916. The borough took shape in stages, and a building's windows usually say something about when it went up.
That is why the borough's rule is written the way it is. It doesn't impose one model on every street. It asks each building to keep its own character, so the right replacement for one building may look nothing like the right one next door. Knowing what your original windows were is the first step, before any product is chosen.
Typology: opening type, divisions and colour
The borough's page on same-size replacement asks that new windows and doors match the form and appearance of the originals and the typology of the building. In plain terms, three things carry over:
- The opening type. A casement (battant) stays a casement, and a hung window (guillotine) stays a hung window. Trading either for a slider changes the typology.
- The divisions. If the original glass is split into sections, the replacement follows the same pattern.
- The colour. This is the one most owners don't expect. Going from white frames to black, or the reverse, runs against the rule just as a new opening type would.
If you hope to change any of the three, raise it with the borough before you sign anything. The pro we match you with can show you what a like-for-like replacement looks like for your windows.
Changing the thermos rather than the window
A milky haze between the two panes means the seal on the thermos has failed and moist air has got in. It won't wipe off from either side. When the frame and sash are still sound, the thermos can usually be replaced on its own: the pro measures the glass, orders a unit to size and sets it in the existing sash. The opening type, the divisions and the colour don't change, because the window doesn't.
There are three fair options, and each suits a different window. Defogging clears the haze without a new unit, and it suits owners who mainly want the view back. A new thermos restores the seal. A new window makes sense when the frame is rotten, warped or drafty all round. Our page on foggy thermos units sets them side by side. The borough doesn't say whether a glass-only swap needs a permit, so ask rather than assume.
Patio doors and screens
- Sliding patio door repair: a door that drags or won't lock usually needs rollers, a lock or an adjustment, and the door stays where it is.
- Patio door replacement: when the frame is done, the new door follows the same rule as the windows, and replacing a sliding patio door always needs a permit in Montréal.
- Window screens: a torn or loose moustiquaire (window screen) is rescreened in its own frame.
- Balcony doors on duplexes: a stiff latch, a cracked glass panel or a worn weatherstrip on an upstairs door is usually a part, not a new door.
What the borough checks in the file
Ahuntsic-Cartierville requires a permit to replace windows and doors, even with the same dimensions. Montréal's permit file generally asks for:
- a quote that includes taxes;
- colour photos, with each window numbered;
- the certificate of location;
- the manufacturer's technical sheet for the new product;
- for a condo, a letter from each co-owner or a resolution of the syndicate.
Those documents are how the borough sees that the opening type, divisions and colour match. A quote that spells them out makes the file easier to read. Requirements change, so confirm the current list on the borough's page before you apply, and see our guide to window permits by borough for how Ahuntsic-Cartierville compares with its neighbours. Have the permit in hand before ordering custom windows.
Ahuntsic-Cartierville questions
Do I need a permit to replace windows in Ahuntsic-Cartierville?
Yes. The borough requires a permit to replace windows and doors even when the new ones are the same size, and it asks that they match the original form, appearance and typology. Plan for the documents: a quote with taxes, numbered photos, the certificate of location and the product sheet. The pro we connect you with can help assemble the file, and our permit guide shows what other boroughs ask.
Can I change the style of my windows in Ahuntsic?
Not freely. The borough treats the opening type and the divisions as part of the building's typology, so a casement is expected to stay a casement and a divided window to keep its pattern. If you want a different style, speak to the borough's permit counter before committing to a product. The pro can show you like-for-like options that respect the rule and still improve on what you have.
Can I change my window colour in Ahuntsic?
Usually not as a simple choice. Colour is listed with the opening type and the divisions as part of the typology a replacement has to match, which surprises many owners. If your frames are white today, expect white again unless the borough agrees otherwise. Ask at the permit counter before ordering, and mention the colour on your quote request so the pro prices the right finish.
Is replacing only the thermos an option here?
Often, yes, and in this borough it has an extra appeal: the window stays exactly as it is. If the frame and sash are sound and only the seal has failed, a new thermos is made to size and set in the existing sash. The borough's page doesn't say whether a glass-only swap needs a permit, so ask before you book. Our thermos page compares the options.
Do you find pros in the north end of the island?
Generally, yes. Ahuntsic and Cartierville sit well within the area where the independent pros we work with take jobs. Tell us your street, what needs doing and, if you can, attach a photo. We pass the request to a pro who handles that kind of work and follow up so it doesn't go quiet. If no one can take your job, we tell you plainly.
