The reference in residential and commercial caulking in Gatineau-Ottawa.

Over time, many environmental factors such as rain, wind, pollution, sun, freezing and thawing modify and deteriorate the initial properties of the sealing products that protect buildings against air and water infiltration. Sooner or later, waterproof joints dry out, contract, crack and become uncoupled from walls, door and window frames. To maximize their energy efficiency, it is recommended that caulking be redone as soon as it shows signs of weakness.
