An opening constructed in a wall or a roof and functioning to admit light or air to an enclosure, usually framed is known as windows. The bottom horizontal frame or part of the window is known as the windowsill. In some buildings may have a sill protruding outside like a platform. That is called the exterior windowsill. In the exterior sills you can keep flower pots, which adds beauty to the room. When you're in an apartment with no outdoor space at all but have a few big windows with exterior sills, you can actually put your plants on the exterior sill. This will make a windowsill garden.

You can replace the exterior windowsill incase it is damaged. To replace the exterior sill you have to remove the inside window stool and apron if the window is trimmed. Cut the exterior sill in half the width provided the jamb is in fair condition. Slip the new sill in place and screw the sill to the jambs. Putty the screw holes. Paint sill and install interior stool and apron. It is not necessary to take out the window or the interior casing.

Types of exterior windowsill

1. Most popular natural stone exterior sill is the limestone windowsill. Sills of limestone protect against damage from moisture entering underneath the window. They also add architectural beauty and lasting value to the building. They are easily trimmed to fit in the exterior of the windows and are tough enough to stand the test of time. The stone sills are available in buff, gray or full color blend.

2. Wood is also an adaptable material and with proper care your wooden sills last a lifetime. If the sill is wooden, perform an annual exterior inspection. Remove and replace loose and cracked putty.


3. Brick windowsills are also very common but brick sills are generally not recommended. If brick sill is used a continuous waterproof flashing material must be used. They are mostly preferred in drier parts of the country and low-rising housing with a protective overhung roof.


With the exterior windowsills becoming popular, installing exterior window shutters have become a trend. They are available in many shapes and sizes. They add colour and style to a home. These shutters are available either in wood or in vinyl or plastic. They are inexpensive and easily available in home improvement stores.
