What is the window sill?

A window sill is part of the window trim, the decorative covering around the window’s edge that protects where the window attaches to the wall and prevents drafts and moisture from getting into the home.

Water, Water Everywhere

The window sill is the flat piece at the bottom of the window. The other parts are the head casing at the very top, the side jambs to the left and right of the window, and the apron positioned directly below the window sill. Together, they offer complete protection around the window.

The sill plays another important part in protecting the home. If you place a level on the window sill, you’ll see it’s probably angled slightly to the outside.

This feature helps water run back outside rather than all over the floor or into the wall through the window track.

While closing a window is usually enough to keep the rain outdoors, any slight opening, either from leaving it ajar before the storm or through a defect in the window, could mean costly repairs without this simple ledge.
