What the houses of Saint-Lambert ask of a new window

Saint-Lambert is a small city with a long building history. The city has inventoried 250 significant buildings and sorted its houses into ten types. Each type has its own window look.

Plexes and boomtown buildings in the old village

The city’s own guide says boomtown houses and plexes are common in the village core, Desaulniers, Alexandra and Parc Victoria. It calls them what defines old Saint-Lambert. Upstairs and downstairs windows line up in a regular rhythm, so a new set must keep that rhythm. Hung windows and casements with a transom are the two looks the guide shows. Our PVC casement frame comes in a 5¾ inch depth with an integrated brick-mould, which suits a brick or stucco wall.

Canadian-style houses with six-pane casements

The oldest houses in the guide are Canadian-style. Their trademark is the casement window with six large panes, often with a storm window. If your house has that look, tell us at the estimate. We check which grid pattern fits your facade before we quote.

King Cottages

Francis King built a type of house found only in Saint-Lambert, and the city commissioned a study on it. The guide gives this type its own window models. A King Cottage is the house where a quick online order goes wrong. We measure on site and compare with the guide before anything is ordered.

Bungalows and townhouses in Préville, Alexandra and Dulwich

Bungalows and town houses carry many windows on a single floor. The guide places bungalows in Préville, Alexandra and Dulwich, and town houses in Préville and Upper Edison. More openings mean a longer quote, so we count every opening and list it line by line.

What rules apply to windows and doors in Saint-Lambert?

Saint-Lambert protects the look of its streets with a site planning and architectural integration program, called PIIA. We read the city’s pages on 12 November 2026. Here is what they say, and what they do not say.

The city publishes a guide of pre-approved window colours

The city’s guide of April 2023 lists five pre-approved window colours: white, charcoal, commercial brown and two sand tones. Any other colour goes to the city council under the PIIA bylaw. The guide exists so owners can avoid that council step. Read it here: Saint-Lambert guide of colours, materials and openings (PDF).

Black frames need council approval

The city’s permit page says plainly that black is not among the pre-approved options. To ask for black, you file the construction permit or certificate form. Plan extra time if you want black. If you want a faster file, choose a pre-approved colour.

The guide shows window models by house style

For each of nine house styles, the guide shows hung and casement models. The city says the proportions are a guide and must be adapted to your existing openings. We bring those drawings to the estimate so the new windows match your style.

Ask before you order: permit and delays

The city’s permit page does not say in plain words whether a like-for-like window replacement needs a permit. It does warn that permits take longer than usual and asks owners to send every document at once. Call the planning department before you order: 450 672-4444, or write to urbanisme@saint-lambert.ca.

What we replace in Saint-Lambert homes

How we serve Saint-Lambert

From our showroom

Our showroom is at 1190 Rue Bégin in Saint-Laurent. Saint-Lambert city hall is 28 km away, about 32 minutes without traffic, measured with OpenStreetMap.

Old Saint-Lambert and Parc Victoria

These streets hold the plexes and boomtown houses. Most of the work here is about matching the existing rhythm of the facade and getting the colour right on the first file.

Préville and the bungalow streets

Here the job is volume: many openings on one floor, plus patio doors and entry doors. We list each opening in the quote so you can compare line by line.

Questions from Saint-Lambert homeowners

Do I need a permit to replace windows in Saint-Lambert?

The city’s permit page does not say. It does say that permits are slow right now and that you must send all documents with the first request. Call the planning department at 450 672-4444 before you sign anything. We can send you the opening sizes for the file.

Can I have black windows in Saint-Lambert?

Black is not on the city’s pre-approved list. You can still ask for it. You file the permit or certificate form and the city council reviews it under the PIIA bylaw. White, charcoal, commercial brown and two sand tones are pre-approved.

Do you replace windows in plexes and old brick buildings?

Yes. We measure each opening at your home and match the window style of the building. For a plex, you get a quote that lists every opening and every door.

How far is your showroom from Saint-Lambert?

It is 28 km and about 32 minutes by car from Saint-Laurent, without traffic. You can visit it, but the estimate itself happens at your home.

Can Rénoclimat help pay for new windows?

Yes, if your home qualifies. For files opened since October 1, 2026, Québec’s Rénoclimat program lists up to $300 per ENERGY STAR window, with a cap of $4,500 for a house and $6,000 for a plex. Doors are not on that list. Your ÉnerGuide rating must improve, so book the energy evaluation first. Details: Québec.ca, Rénoclimat.
