Sills are fixed on the outside of a window ledge. This forms the weathering part of an opening, which protects the building fabric below the window opening. When rain falls on the window, it drips down and lies on the ledge when the sill is not fixed. This can eventually cause dampness to the wall below. This also may allow water to seep through, causing efflorescence. Another issue can be having rain tears appearing on the building facade below the window.
Window sills can be inbuilt during construction or after the building construction. Different types of sills are available in the market. This may include clay, concrete, stone, or wood. Each type has its advantages, and preference is on the homeowner to choose the desired variety. When using the in situ ones, they should be protected until the finishes stage is complete. The wood typeis used in dry areas due to the vulnerability of the weather.
The clay or concrete sills are usually fixed after the window frame is in place. All sills should be done with an overhang or projection from the wall. This should be a minimum of two or three inches from the wall. They should also have a fall to ensure water and dirt flow away. They should be about one inch in thickness. It is crucial to ensure that they are placed almost half an inch above the bottom frame. This will allow the sash to open without touching them.
The fixing of sills starts with measuring the projection and window recess into the wall. This is measured from outside. The window ledge is then made level. The first and last sill is then bedded on strong mortar. A string and spirit level is used to align the top and overhang distance. It is essential to recess them two inches into the wall on both ends. The rest is then bedded on the mortar and space filled out. Below the sills, mortar is filled to make adequate space. A matching sill color can be painted to have a uniform decoration.

The tool may be a saw, a hand saw, or a wood chisel. All in all, choose the tool that best fits your skill level and finish the cut.
It better you use a flat pry bar if you're not powerful enough to free each piece of board with your hands. Wear a decent heavy-duty pair of work gloves when you're trying. Take your time, and you're expected to be able to work each piece free of charge.
Set the jaws to the vice grips, but they barely bite into the nail. Next, close the jaws around the nail and work each nail loose slowly. Sometimes the nose of the lock pins may be used to apply leverage.
Determine the actual size from the two missing sections of the old sill. Don't forget to figure out the saw blade's thickness as you measure the blade's total length.
Don't build up the wood to make your new sill, but instead, if possible, use one piece of stock. When moisture tends to be a big concern, use redwood, cypress, or cedar.
Design the outer edge so that it is rounded.
Sand the board thoroughly and paint with primer paint on each side and edge.
Slide the new sill in place and nail it securely to the galvanized nails. Set each nail just a little bit below the surface and fill it with caulking. Often, caulk around the edges of the freshly installed sill.
