Vinyl fencing will last for many years, provided it is given proper care. Routine care should include regularly hosing to clean the accumulated dirt. Hosing should be done with a high-speed nozzle, which will take care of all accumulated dirt and debris in one sweep. If given proper treatment, there’s no reason vinyl fencing will not last 20 to 30 years, and you may find that many vinyl fences come with lifetime warranties. Even in high-traffic areas, you will find vinyl that fencing, if given the proper care and not accidentally damaged, could even outlive the siding on your house.
