What is a Window Sill

You can find a window sill at the bottom of the window structure. You might consider it the best known part of standard, traditional window with its shelf-like trim found at the base of a window.

From structural integrity to decorative space, window sills provide a variety of functionality and services.

Window Sill Planter

You can also find window sills on the outside of your home. Whether inside or outside, it’s an excellent place to have a window sill planter. You can bring the rooms in your house alive with living house plants and cactuses. It’s the perfect way to have a green space.

Some window sill planters can attach right to the outside of your house. Or you can buy slim-shaped planters that fit perfectly in the window.

Window Sill Shelf

From storing books to house plants, window sill shelves are fantastic for maximizing the space in your home. You can turn a simple sill into a workspace, sitting area, or convenience table with a window shelf. You could also create hanging shelves that suspend in the window or create a lounge space for your cat.

How to Install a Window Sill

Window sills are an integral part of the interior design, and a professionally executed sill installation can create a classy finish. A window sill consists of two parts – the shelf at the base of the window and the stool underneath the shelf.

  1. First, mark a ¾ inch reveal mark on the window jambs
  2. Then, using a scrap piece of trim, hold the trim up to your marks and draw a reference line on each side of the window.
  3. Determine your sill overhang – typically ¾ inches.
  4. Next, cut the window sill stool to length.
  5. Trim the stool and set it in place so it’s snug tight to the window and facing walls.
  6. Attach the shelf with finishing nails.
  7. Then, secure the side window trim.

Adding window sills can create a customized and stylish look.

  • Granite – Commonly found in kitchen and dining room windows.
