One of the biggest causes for peeling paint is moisture. Once the material the paint is ‘stuck’ to gets wet, the paint loses its adhesion quality and begins to pull away from the surface. This allows more moisture to get in, which causes more reduction in adhesion, etc. Caulking expands and contracts with heat and cold to ensure the surface is completely sealed from moisture. It is our opinion that all holes, cracks, seams and nail heads have new caulking applied to them, not just the failing areas. In this way, you are guaranteed the best possible protection from the damaging effects of water.
