What we see in Laval
Four situations specific to Laval homes
One Laval dwelling in three was built between 1961 and 1980. On top of that, the City's planning code (CDU-1) sets which materials a facade can use.
Post-war bungalows
The City ties the hip-roof bungalow to the 1950s and 1960s, with a mix of brick, stone, vinyl, wood or aluminum. When the lightweight siding is done, we strip it all, install an air barrier and Isoclad insulation, then the new siding.
Vinyl across the whole front?
In most residential areas, vinyl and fiber cement are capped at 40% of each main facade. The sides and back can take them. Existing vinyl can be redone with a material of the same type (acquired rights).
Three materials, colours included
The code allows 3 materials on the main facades, and two colours count as two. Brick, two shades of lap siding and stone is one too many. We check the combination before ordering.
Sainte-Rose, Saint-Vincent-de-Paul, Sainte-Dorothée
These heritage areas require a PIIA if the new material is not similar. In Sainte-Rose and Saint-Vincent-de-Paul, the City favours brick and horizontal wood siding, such as Maibec wood.

The Laval job
A Laval home redone completely: tear-off, AirLock air barrier, Isoclad insulation, James Hardie fiber cement in Stone grey. 1,600 sq. ft. in 3 weeks, with the occupants living in. The other two jobs are in Montreal.
Switching materials?
We look up your address in the City's Info-règlements tool before giving you a price. You know right away whether you need a permit or a PIIA.

Permits and bylaws in Laval
What the City asks for
Laval has applied its planning code (CDU-1) since November 2022. The rule starts with one question: same material or new material?
Rules checked on October 1, 2026 on laval.ca.
Same material
Replacing siding with the same material, with or without insulation, needs no permit. The exception: your address falls under a PIIA.
New material
Going from vinyl to fiber cement or steel needs a permit. You need a recent certificate of location, and the application goes in online through Mon Dossier. Allow 30 days for a single-family home once the file is complete.
Cost and documents
The City's 2026 fee: $92 for the first $20,000 of work, plus $2.50 per additional $1,000. In a flood zone, the certificate of location must show the flood elevations.
PIIA area or heritage building
A PIIA comes on top of the permit: the City reviews the project, then the executive committee decides. It is free for a single-family home, but it adds time. A classified building also needs approval from the Ministère de la Culture.
What drives the price
What siding costs in Laval
Every house gets measured: we do not publish a price per square foot. Here is what moves a quote in Laval. Financing available through iFinance Canada.
The allowed material
Vinyl, fiber cement, steel or wood: the type your area requires on the front steers the choice, and the budget.
Facades and area
How many walls are redone, the height, the corners, the soffits and the fascia.
Tear-off and insulation
Removing the old siding, repairing the framing if needed, adding an air barrier and insulation panels.
Permit or PIIA
A new material adds the City permit, sometimes a PIIA, and their delays. A like-for-like replacement skips them.
Rénoclimat
Québec helps fund exterior wall insulation if the energy evaluation is done before the work. Book it before we strip the siding.
Heritage program
A building on Laval's heritage inventory can get help for work that respects the original. You apply before the work starts.
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 in Laval: 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 Laval?
It depends on the material. The same material, with or without insulation, can be replaced without a permit, unless a PIIA covers your address. A new material needs a City permit.
How long does the permit take, and what does it cost?
The City states 30 days for a single-family home, counted from a complete file. A PIIA adds time. In 2026, the permit costs $92 for the first $20,000 of work, plus $2.50 per additional $1,000.
Can I put vinyl on the whole front of my house?
Not always. In most residential areas, vinyl and fiber cement are capped at 40% of each main facade, while the sides and back can take them. If your front is already vinyl, acquired rights let you redo it with a material of the same type.
My house is in Old Sainte-Rose or Saint-Vincent-de-Paul. What changes?
These are heritage areas. Switching to a material that is not similar requires a PIIA, and the City favours brick and horizontal wood siding there. The PIIA application is free for a single-family home.
What renovation grants are available in Laval?
For siding, two programs can apply. Québec's Rénoclimat helps fund exterior wall insulation if the energy evaluation is done before the work. The City's revitalization program covers buildings on its heritage inventory.
What does exterior siding cost on average?
There is no reliable average: material, area, added insulation and access all move the number. In Laval, the material allowed on your front and the permit also count. The quote is free and follows a visit.
