“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!”

Step 4 — Detailed quote
A clear quote, no surprises
Your quote includes materials, labor, timeline and warranties. Here are the 4 factors that make a project’s cost vary.
Surface to caulk
The number of linear meters of joints to treat is the main factor, windows, doors, foundations and material junctions.
Required sealant type
Silicone, polyurethane, expanding foam, each application needs a different product with its own cost and durability.
Condition of existing caulking
If the old caulking is degraded and stuck, removal takes longer. Dirty or greasy surfaces also require extra preparation.
Accessibility
High areas (2nd or 3rd floor) require scaffolding or lifts, which increases installation time and cost.
