Often used as a shelf for plants or other decorations, a window sill is part of the trim area at the bottom of the window where the wall and window meet. It helps to prevent drafts and moisture from getting into the home. Installing a window sill isn't overly difficult, but it's a project that most homeowners leave to professionals.

To add a sill to an existing window, the horizontal area is cleared of siding, Sheetrock or other surface material and is stripped clean down to the frame itself. The window and its framework are not disturbed, but the flat area in front of it is completely bared.
There are several factors that can affect the cost of the project. If an existing sill needs to be removed or if the frame beneath the window requires repair, this can add to the final price. The cost of the various types of wood can vary greatly as well. If the sill is primarily for aesthetic appeal, a highly decorative wood may be selected. If it's to be used for potted plants or other heavy items, a more rugged wood known for its strength might be better. The type of finish and the amount of sanding or priming necessary will also play into the costs.
The sill and apron add beauty and functionality to a window, and their appearance is worth investing in a professional. A trim and woodworking specialist has the knowledge and tools to ensure homeowners receive the best results.
