An interior windowsill is the bottom portion of the window, usually having a lip that overhangs the trim molding. In this tutorial, the author shows how to replace interior windowsills from some of the most common builder grade windows. While interior window trim might not be as susceptible to damage as exterior trim, it is still important to keep it in good condition. If replacing trim on existing windows, remove all of the trim down to the rough opening with a small pry bar.

To avoid damaging your walls when replacing trim, remove old window trim molding, attach side window trim, top window trim, final top window trim, bottom trim, and pry off the sill using a prybar or chisel. Use a wide flat prying bar to pull off the trim, putting a thin wide piece of wood behind the pry bar to avoid wall damage.

In summary, this video provides a step-by-step guide on installing interior window trim, covering the basics, tools, and steps for beginners and intermediate carpenters.
