Vinyl siding looks similar to horizontal wood siding but doesn't require as much maintenance. Vinyl siding systems can be applied right over old siding but are easier to apply over solid sheathing. It doesn't rust or corrode but vinyl, which is actually polyvinyl chloride (PVC), does become more brittle as it gets older.
Some vinyl siding manufacturers also offer a range of decorative classic millwork that coordinates with their systems. These include door and window surrounds, shutters, corner posts, dentil moldings, and more.
