Save money maintaining the window sills in your home by
protecting them from water. Older windows are prone to get moist, and the
water runs down and gets the wood on the window sill wet. Apply a few
coats of wax on the window sills, and the water won't penetrate the wood.
Replace single pane windows
with Double Pane windows when you can afford it.
Paint wooden window sills with
semi-gloss paint to seal the wood.
Check you sills often, and if
there is water, wipe it off.
