What Saint-Laurent homes ask of a window
Saint-Laurent had 39,155 households in the 2021 census, up 4.7% from 2016. Owners and tenants split the borough almost evenly, and 52.2% rent. One home in four (25.3%) is a single-family house, far above the Montréal average of 13.9%. The largest group, 44.7%, lives in a duplex or a building under five storeys.
Bungalows and cottages around Dutrisac
Dutrisac has the highest share of single-family houses in the borough, at 40.7% of its homes. A bungalow keeps all its windows on one level, which makes it simple to price the whole house in one visit. Brick sills and stone trim decide the fit, so we measure the opening you have and not a catalogue size.
Walk-ups and small buildings with many balcony doors
Close to half of the borough’s homes (44.7%) sit in a duplex or a building under five storeys. These façades repeat the same openings floor after floor, plus balcony doors. If you own one, we list every opening on one quote so the new windows match from top to bottom.
Where repairs are most often needed
In 2021, 8.0% of Saint-Laurent homes needed major repairs, and that count grew 23.5% from 2016. The Grenet area has the highest share, at 13.2% of occupied homes. If you live there, bring the whole list of tired windows and doors, not only the worst one.
Bois-Franc: higher housing costs, more condos to check
Bois-Franc has the highest median housing costs in the borough, at $1,340 a month in 2021. If your home there is a condo, read your declaration of co-ownership before you order. It can set the colour, the frame and the glass for every unit on the façade.
Do I need a permit for windows and doors in Saint-Laurent?
Usually not for a same-size swap. The City of Montréal page for Saint-Laurent (updated 30 July 2026) says you generally do not need a permit to replace exterior doors and windows with models of the same dimensions. Ask the permit counter before you sign if anything about your address is unusual.
Same dimensions: generally no permit
The city’s word is “generally”, and it matters. A new opening size, a heritage address or a change to the façade can bring a review. Read the city page for Saint-Laurent, then confirm your own address with the counter. We tell you at the estimate if we think your job falls outside the simple case.
Street façade work can need a PIIA approval
The city says some work that changes the street-facing façade of an existing building can need approval under its site planning and architectural integration programme (PIIA). It asks you to contact the permit counter before you start. The counter then says whether you must apply and what to bring. The page lists the zoning by-law as the main rule for Saint-Laurent.
The Saint-Laurent permit counter
The counter is at 777 boulevard Marcel-Laurin, about 3 km and 7 minutes from our showroom. It is open Monday, Tuesday, Thursday and Friday from 8:30 to noon and from 1:00 to 4:30 pm. It is closed on Wednesday. The borough also runs an online permit assistant on its own site.

Bois-Franc
3 km and about 6 minutes from our showroom, without traffic. Send photos of the windows, and for a condo, the contact of your syndicate. We can then plan the visit around the approval.
Vieux-Saint-Laurent
4 km and about 7 minutes. The older streets mix home types, so we quote from the openings we measure and never from the street name.
Dutrisac and Chameran
5 to 6 km and 10 to 11 minutes. Expect brick bungalows and low-rise buildings. Tell us which windows face the street and which face the yard, and we price them in two groups.
Saint-Laurent is 3 to 6 km from our showroom
Our showroom stands in Saint-Laurent, so these are the shortest drives of all our areas. We measured each drive on OpenStreetMap roads and rounded it, with no traffic counted.

Questions Saint-Laurent owners ask
Is a permit needed to swap windows in Saint-Laurent?
Generally no, when the new windows have the same dimensions as the old ones. The city page for Saint-Laurent says so. It also says to call the permit counter before you start if the work touches your street façade.
Where can I see your windows and doors in person?
Our showroom is at 1190 Rue Bégin in Saint-Laurent and opens Monday to Friday from 9:00 to 16:00. Touch the frames, compare the glass, then book your free in-home estimate. The written quote comes after that visit.
Does my home need a heritage or PIIA review?
Only some do. The city says certain work that changes a building’s street façade can need PIIA approval. Phone 311 or the permit counter with your address before you choose a model.
Can you replace windows in a Saint-Laurent condo?
Yes. Read your declaration of co-ownership first, because it can fix colours, finishes and the rules for the façade. Bring your syndicate’s contact to the estimate so an approval does not hold up your order.
Can a grant lower the price of new windows?
It can. Rénoclimat pays $300 per window, up to $4,500 for a house and $6,000 for a multi-unit building, on files opened since October 1, 2026. Conditions apply, so read the rules on quebec.ca before you sign.
