What Verdun and Nuns’ Island buildings ask of a window

The borough had 35,080 households in the 2021 census, up 3.2% from 2016. Of those, 62.4% rent. Apartments of all types are 90.0% of occupied homes, and two in three (67.3%) are in a duplex or a building under five storeys. Single-family houses, including semi-detached and row houses, are 10.0%.

Plexes and walk-ups: many windows, many sizes

Most Verdun homes are in a duplex or a small building. That means many openings of different sizes on one façade, often brick, often with an outside staircase in front or at the back. We measure every opening, because a plex owner replaces a few windows each year or all of them at once, and the new ones must match.

Brick walls and old openings

On older brick walls, the opening decides the fit, not the catalogue size. We check the sill, the brick moulding and the lintel before we quote. A made-to-measure window fits the opening you have, so the brick stays untouched.

8.8%

Verdun-Centre has the most homes needing major repairs

According to the people who live in them, 8.8% of Verdun homes need major repairs, and Verdun-Centre has the highest share at 10.9%. Bring the full list of problem openings to the estimate, not only the worst window.

18.0%

Nuns’ Island is a different market

Nuns’ Island has the highest share of single-family houses in the borough, at 18.0% of its homes. It also has condo buildings. A condo owner needs the co-ownership’s approval before any permit request, and a house owner on the island deals with the same borough permit counter as the rest of Verdun.

What does the Verdun borough require for windows and doors?

A permit, even for same-size replacement. The City of Montréal page for Verdun (updated 30 July 2026) says you must get a permit to replace exterior doors and windows. Get it before work starts.

The permit fee and what to bring

The city page for Verdun sets the fee at $9.80 per $1,000 of work. The minimum is $167.40 for a residential building and $491.70 for a commercial or mixed building. Bring a quote with taxes, a certificate of location, the manufacturer’s data sheet, and recent colour photos of the façades being changed and of your immediate neighbours’ façades. Fees are not refundable.

Condo owners: the co-owners’ approval comes first

In a condo, the city asks for a letter of authorization from each co-owner or a resolution of the syndicate of co-owners. Read your declaration of co-ownership before you order, because it can say which windows and doors, which colours and which finishes are allowed.

Original look and heritage areas

The Verdun section of the city page sets door rules: the glass keeps proportions close to the original door, or is a clear rectangle 106.6 to 137.1 cm high, and transoms above doors must be kept or restored. Wartime houses get their own exception. Extra fees can apply if the building or its area has heritage value. A site planning review (PIIA) can apply in parts of the borough when work changes what is visible from the street, including replacing doors and windows. The page names no Verdun fee for it, so ask the permit counter.

The Verdun permit counter

Call 311, or visit the permit counter at 4555 rue de Verdun, office 104. It is open Monday to Thursday from 8:30 to 12:00 and 1:00 to 5:00, and Friday from 8:30 to 12:30. Ask if your address needs a PIIA review before you choose a model.

Questions Verdun owners ask

Do I need a permit to replace windows in Verdun?

Yes. The city’s Verdun page says you must get a permit to replace exterior doors and windows with same-size models. The fee is $9.80 per $1,000 of work, with a minimum of $167.40 for a residential building.

Do I need my condo board’s approval?

Yes. In a condo, the city asks for a letter from each co-owner or a resolution of the syndicate of co-owners with the permit request. Check your declaration of co-ownership first for rules on colours and finishes.

Does my Verdun house need a heritage review?

It can. The city says a PIIA review can apply in certain parts of the borough for work visible from the street, and extra fees can apply for buildings with heritage value. Call 311 or the Verdun permit counter with your address.

Can I replace only the windows on the street side?

Yes. We quote the openings you choose. If you plan to do more later, tell us at the estimate, so the new windows match the ones you add next year.

Is there a government grant for new windows?

Quebec’s Rénoclimat program pays up to $300 per window. The cap is $4,500 for a house and $6,000 for a duplex, a triplex or a multi-unit building. It applies to new files since October 1, 2026, and conditions apply. See quebec.ca for the latest rules.
