Exterior siding
in Longueuil and the South Shore
The right material for your city, the permit file prepared, the work done by a building envelope crew.

The short version
Replacing your siding on the South Shore
We replace and insulate exterior siding on homes across the Longueuil agglomeration. Each of the five cities requires a permit and bans certain materials, so we check your address before we quote.
Five cities
Longueuil (including Saint-Hubert and Greenfield Park), Brossard, Boucherville, Saint-Lambert and Saint-Bruno-de-Montarville.
The permit
Required everywhere to replace siding. From 30 days in Boucherville to at least 10 weeks in Saint-Lambert when a PIIA applies.
The crew
We come from Montréal-Nord, across the St. Lawrence.
The quote
Free, after a visit and measurements. Financing available through iFinance Canada.
What we see on the South Shore
Four situations specific to the area
In Longueuil, 39% of homes were built between 1961 and 1980. And each city in the agglomeration has its own rules on materials.
Homes from 1961 to 1980
The original aluminum or vinyl is at the end of its life, over poorly insulated walls. We strip it all, inspect the framing, install an air barrier and Isoclad insulation, then the new siding.
"I want vinyl"
Vinyl is banned in Saint-Lambert, in Saint-Bruno and in Old Boucherville. Longueuil and Brossard allow it, alongside the masonry they require. Elsewhere, the choice is fiber cement, steel or wood, depending on what the city accepts.
The brick that stays
A Longueuil house keeps at least 50% brick or stone on every facade. Brossard asks for 65% across all facades of a single-family home, Saint-Lambert 60% per facade. So we redo the siding around the masonry, as on our board and batten job in Longueuil.
Old Longueuil, Old Boucherville, Saint-Lambert
In the Vieux-Longueuil heritage site, any exterior change needs 45 days of notice. In Old Boucherville, every exterior renovation goes through a PIIA, and opaque treated wood is one of the allowed materials. In Saint-Lambert, black is not on the list of pre-approved colours.
Three jobs in the agglomeration
Longueuil: slate grey Maibec board and batten, 1,100 sq. ft. in 11 days, brick base kept. Saint-Hubert: Distinction steel in Desert over Isoclad insulation, 1,800 sq. ft. in 2 weeks, with the windows replaced at the same time. Saint-Lambert: ACM panels and Mac Métal steel on a 1970s house, 1,300 sq. ft. in 2 weeks.
Is your house in Old Longueuil or Saint-Lambert?
We check the PIIA before the quote, not after. You know right away whether your project goes to the committee, and what timeline the City states.
Permits and bylaws on the South Shore
Five cities, five sets of bylaws
The agglomeration sets the land use plan, but each city has its own zoning bylaws and issues its own permits. All five require a permit to replace siding.
Rules checked on October 1, 2026 on the five city websites.
Longueuil, Saint-Hubert, Greenfield Park
You apply online, with elevations, the materials and their share of each facade. Replacing more than 25% of a street-facing wall with another type of material requires a PIIA in the zones it covers. The Vieux-Longueuil heritage site requires 45 days of notice.
Brossard
You apply by email or at City Hall. Changing cladding visible from the street goes through a PIIA, unless the new material is in the same class and a similar colour.
Boucherville
A permit is always required: 30 days once the file is complete, $71 in 2026. In Old Boucherville, every exterior renovation goes through a PIIA, and both vinyl and metal lap siding are banned.
Saint-Lambert
Vinyl is banned everywhere, with 3 materials and 2 colours at most. Changing the type or colour of siding visible from the street goes through a PIIA: allow at least 10 weeks.
Saint-Bruno-de-Montarville
Permit in 30 days, vinyl banned across the city. Changing the type or colour on the front or side walls goes through a PIIA, except lightweight siding in grey, brown, beige or natural-stained wood.
What drives the price
What siding costs on the South Shore
Every house gets measured: we do not publish a price per square foot. Here is what moves a quote in the agglomeration. Financing available through iFinance Canada.
The allowed material
With no vinyl in Saint-Lambert or Saint-Bruno, the choice is between fiber cement, steel, aluminum and wood, and the budget follows.
Facades and brick kept
How many walls are redone, how much brick stays, the height, the soffits and the fascia.
Tear-off and insulation
Removing the old siding, repairing the framing if needed, adding an air barrier and Isoclad panels.
Permit and PIIA
The City permit, plus a PIIA in the areas it covers: municipal fees and weeks on the schedule.
Rénoclimat
Rénovation Québec has been suspended since April 1, 2025. Rénoclimat is still open for wall insulation, if the energy evaluation is done before the work.
Heritage programs
Boucherville and Saint-Bruno help replace vinyl with original cladding on heritage buildings. Switching to vinyl or fiber cement does not qualify.
They trust us
“Nous avons fait appel à EJA pour le revêtement extérieur (acier MAC) de notre agrandissement. Nous avons été en contact avec Emir pour la planification du projet et avec Jérémy et leur équipe pour l'exécution. Nous sommes très satisfaits de la qualité et de la rapidité d'exécution du travail effectué. Les commentaires Google, sur lesquels nous nous sommes fiés, sont bien fidèles à la réalité. Je recommande donc grandement les services de l'entreprise EJA pour vos projets de revêtement extérieur.”
“Mon premier contact avec l'équipe a été avec Emir. Il est venu rapidement, retournait ses appels. Il m'a bien accompagné pour la soumission, le permis et s'est montré patient avec le financement. Ensuite, Jérémie et son équipe ont fait la pose. Ils sont respectueux, vérifient les morceaux avant de les installer et ont corrigé des défauts sur la maison pour empêcher l'eau de s'infiltrer. À la fin de chaque journée, Jérémie faisait le tour avec nous et le chantier restait propre. On n'a pas eu de surprise, la communication était bonne et les délais respectés. Je recommande !”
“J'ai fait appel à EJA pour le revêtement extérieur de ma maison, qui était vraiment en mauvais état. Je suis absolument ravi du résultat : l'équipe a travaillé avec un grand souci du détail, et le changement est spectaculaire. Ma maison a retrouvé toute sa beauté, presque comme neuve. Je recommande vivement leurs services à quiconque veut redonner vie à l'extérieur de leur maison.”
“Très bonne expérience avec Jérémie et son équipe ! On a fait refaire une terrasse en hauteur, qui sert aussi de toit, et permet l'écoulement des eaux. L'équipe a bien travaillé dans des conditions météo difficiles et en hauteur. Le résultat est bien fait. Les communications étaient bonnes.”
“Excellent service. On a fait appel à EJA pour des travaux de calfeutrage pour notre copropriété. Très pro, bonne communication avant, pendant et après les travaux. 5/5”
“Les Entreprises EJA did an excellent job on the complete overhaul of the wooden siding of our chalet, and stand highly recommended for their reliability and conscientious work! Emir, Jeremie and their team reassured me that there are still hardworking young people out there, for whom a job well-done is not only a question of money well-earned, but also of professional pride and honor!”

Frequently asked questions
Siding on the South Shore: your questions
Have other questions? Our team is here to help, at no cost and with no obligation.
Do I need a permit to replace my exterior siding in Longueuil?
Yes, Longueuil requires a permit to renovate the exterior of a house. A repair that changes neither the dimensions, the shape nor the architectural features can be exempt, except in a PIIA or heritage area. Brossard, Boucherville, Saint-Lambert and Saint-Bruno also require a permit.
Can I install vinyl siding in Saint-Lambert, Saint-Bruno or Old Boucherville?
No. Vinyl lap siding is banned across Saint-Lambert and Saint-Bruno-de-Montarville, and in Old Boucherville, where metal lap siding is banned too. In Longueuil and Brossard, vinyl is allowed alongside the required masonry.
My house is in Old Longueuil. What changes?
Vieux-Longueuil is a cited heritage site of more than 950 buildings. Any change to the exterior appearance, walls included, needs at least 45 days of notice and goes to the local heritage council. We build that into the schedule from the quote.
What renovation grants are available in Longueuil?
The Rénovation Québec program has been suspended in Longueuil since April 1, 2025. For siding, Rénoclimat can help if you insulate at least 20% of the walls, with an energy evaluation done before the work; siding alone does not qualify. Boucherville and Saint-Bruno also have heritage programs for going back to original cladding.
How long does a siding permit take on the South Shore?
Boucherville and Saint-Bruno state 30 days once the file is complete. In Saint-Lambert, where changing the type or colour visible from the street triggers a PIIA, allow at least 10 weeks. Longueuil and Brossard do not publish a timeline, and a PIIA adds to it.
What does exterior siding cost on average?
There is no reliable average: material, area, insulation and access all move the number. On the South Shore, the material your city allows and how much brick must stay also count. The quote is free and follows a visit.
