Door and window stone sill caulking

Do you know what a window sill is? This is the sill at the bottom of the window on your exterior wall. The sill is usually made of concrete, wood, or aluminum and is primarily used to redirect water away from your exterior wall. For brick houses, it even reduces the risk of the bricks shattering.

Why caulk a window sill?

Just like caulking your window, properly caulking a sill reduces the risk of water infiltration. A cracked brick window sill has serious consequences. For example, water can seep into the crack and cause the brick to shatter. If you don’t have a brick wall, water can still slip behind the wall and accelerate fungus growth.

Mold problems are not insignificant, because they affect the structure of your building as much as the health of the residents. What’s more, the majority of window sills are made of asphalt, cement or concrete. Stone is a friable material, and water is its main enemy. With freezing and thawing, the stone sill deteriorates and becomes a weakness in the sealing of your window.

However, even with an aluminum window sill, you have to remember to inspect it. Nothing says that a gasket doesn’t need to be caulked, at some point or another.

If you notice a crack in your masonry sill, it is strongly recommended that you caulk it quickly to avoid costly problems.
