MK Calfeutrage Inc. specializes in commercial, institutional and residential window and door caulking. For over 20 years, we have been providing high-quality building sealing services throughout Greater Montreal, effectively preventing any air or water infiltration.


When should the caulking be replaced?

When it begins to crack, split and peel off or when another alarming sign is noted, it is advisable to have its caulking inspected by specialists to prevent water infiltration, rotting of the building envelope as well as the presence of insects.
