When an old window sill is rotten or damaged beyond repair, the best alternative is to replace it with a new one. Often the wall surface at the base of the window is damaged by moisture from condensation, or a hungry dog who used the sill as a chewing toy. Whatever the cause, installing a new sill provides protection and adds a stylish detail to the window. If there is moisture damage to the wall, make the repair and then replace the sill. And if your window was built without a sill, adding a new one will be a nice upgrade.
But now there are vinyl sills that are installed with adhesive in two styles. One has a straight cut basic style, and the other wraps around the sides of the wall, giving it a custom look. At the manufacturer's Web site, www.sill-rite.com, you can learn about the different styles, how to measure a window for a new sill and what's involved installing one.
A carpenter or window replacement contractor will charge $133 to install a 4-foot-wide sill, assuming no repair work is required on the window and wall (that will cost more). You can buy the sill for $50 and do it yourself, assuming you have some carpentry skills and tools, and save 64 percent. You'll need a tape measure, carpenter's square, saber or small circular saw, construction adhesive and weatherproof caulking and a caulk gun.
