What Sud-Ouest buildings ask of a window

The borough had 43,635 households in the 2021 census, up 10.5% from 2016. Of those, 65.2% rent. Apartments of all types are 91.4% of occupied homes, and two in three (66.5%) are in a duplex or a building under five storeys. Single-family houses are 8.6%.

Plexes and row houses keep their original look

If your windows and doors are original, the borough says the replacement must look exactly the same, in shape and model. If they are not original, you pick a model the borough’s table allows for your building type and sector. This is a façade rule, and a façade is every exterior wall except one facing the back yard.

Pointe-Saint-Charles has more houses than the rest of the borough

Single-family houses are 15.3% of Pointe-Saint-Charles homes, the highest share in the borough, and 11.9% of its homes need major repairs, also the highest, according to the people who live in them. Bring the full list of problem openings to the estimate, not only the worst window.

Saint-Henri, Griffintown and the rail workshops have special review areas

The borough’s site planning review (PIIA) has special provisions for Griffintown, the Pointe-Saint-Charles rail workshops and the Saint-Henri village cores. If your building is heritage-listed or in a significant sector, the borough reviews exterior window and door changes before a permit is issued.

Near the Lachine Canal, the façade rule changes

The borough page says a few exceptions apply if your building is a significant architectural witness, or if you are close to the Lachine Canal. The permit counter tells you which wall counts as a façade at your address.

What does the Sud-Ouest borough require for windows and doors?

A permit, even for same-size replacement. The borough’s page on montreal.ca (updated 30 July 2026) says the models you submit must comply, so get the permit before you sign a contract for the work.

PVC outside is not allowed, a hybrid is

The borough prohibits PVC as the outside finish of windows, frame included, across its whole territory. You can choose a hybrid model instead. Our catalogue lists hybrid PVC and aluminium windows, including casement, awning, single-hung and single-slider models. For a significant architectural witness (a locally listed building, a building under Quebec’s cultural heritage law or a place of worship), the outside finish must be wood or aluminium.

ENERGY STAR for a home’s windows

Windows, skylights and patio doors serving a dwelling must meet ENERGY STAR for climate zone 2, with a minimum energy rating of 29. Original glass blocks and stained glass must be kept and put back in the new opening. Side windows, door transoms and carriage-door openings may not be blocked off.

Fees, documents and the permit counter

The borough page sets the fee at $9.80 per $1,000 of work. The minimum is $167.40 for a residential building. Extra fees can apply to buildings with heritage value. Bring a quote with taxes, the manufacturer’s data sheet, recent colour photos of the façades being changed and of your immediate neighbours’ façades. In a condo, add the syndicate’s authorization. Book the permit counter for details.

Heritage review (PIIA) and the interactive map

Most exterior work on significant buildings, including replacing an architectural component, goes through the PIIA review. The study fee for architectural components is $213, on top of the permit. Check your address on the borough’s interactive map: switch on the “Zonage et PIIA” layer and type your address.

What we replace in Sud-Ouest homes

How we serve the Sud-Ouest

Saint-Henri and Little Burgundy

14 to 15 km and 17 to 19 minutes from our Saint-Laurent showroom, without traffic. Bring your address to the borough’s map before we visit, so we know if you are in a PIIA area.

Pointe-Saint-Charles

17 km and about 22 minutes. This is the longest drive of our Sud-Ouest stops, so we do the measuring visit and the estimate in the same trip.

Côte-Saint-Paul and Ville-Émard

14 to 18 km and 18 to 21 minutes. LaSalle is next door and has its own page, and so does Lachine.

The Sud-Ouest is 14 to 18 km from our showroom

We drive from 1190 Rue Bégin in Saint-Laurent. Distances are measured on OpenStreetMap roads, rounded, with no traffic.

Questions Sud-Ouest owners ask

Do I need a permit to replace windows in the Sud-Ouest?

Yes. The borough requires a permit to replace exterior doors and windows with same-size models. It recommends getting the permit before you sign a contract, because the models you submit must comply. Fees start at $167.40 for a residential building.

Can I install PVC windows in Pointe-Saint-Charles or Saint-Henri?

Not with a PVC outside finish. The borough prohibits it, frame included. A hybrid model is allowed. We list hybrid PVC and aluminium windows, so tell us at the estimate that you are in the Sud-Ouest.

Can I change the colour of my windows?

Yes, except on a significant architectural witness. The borough allows a colour change on an original component for other buildings. If your building is heritage-listed, the outside finish must also be wood or aluminium.

What happens to my original stained glass or glass blocks?

They must be kept and re-installed in the new opening. Side windows and door transoms may not be closed off. Show us these details at the estimate so the quote includes them.

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 residential building. It applies to new files since October 1, 2026, and conditions apply. See quebec.ca for the latest rules.
