Wooden window sills must be painted or sealed in order to be weatherproof and durable. Modern wooden window sills are typically clad with a durable waterproof material for easy maintenance and extra insulation.
Stone window sills are completely durable and typically need no sealing or treatment in order to withstand the elements. Tile sills are less common than wood or stone and are often found on older homes.
