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
Everything you want to know
Have other questions? Our team is here to help, at no cost and with no obligation.
What is the best exterior cladding?
There is no single answer: the "best" cladding is the one that fits your style, your budget and your home’s architecture. James Hardie fiber cement offers exceptional durability (50 years), Canexel is very popular in Quebec for its low maintenance, and Maibec wood for its premium authenticity.
What is the cheapest exterior cladding?
Vinyl remains the most affordable option to buy, but long-term value matters too. Canexel and aluminum offer excellent value with less maintenance over several decades.
How long does it take to do a house?
A complete transformation usually takes from a few days to two weeks, depending on the complexity of the project and the materials chosen. We give you a precise schedule right at the start of the project.
Should I do my exterior in brick or cladding?
It comes down to style and structure. Brick is permanent and noble but costly. Modern cladding (Canexel, fiber cement, steel) offers contemporary designs, faster installation and more accessible costs, while being extremely durable.
Do you offer financing?
Yes! We partner with iFinance Canada, which offers flexible financing solutions for your exterior renovation projects. Ask us for the details during your free quote.
Do you handle building permits?
Absolutely. Our turnkey service includes full management of the municipal permits required for your work. You have nothing to do on that side, we take care of everything.
Which areas do you serve?
We work on the island of Montreal, in Laval and across the South Shore: Longueuil, Boucherville, Saint-Lambert, Sorel, Saint-Hyacinthe and more. Contact us to confirm your area.
