Vinyl rails cost about $20 to $40 per linear foot, not including labor costs. However, since they don’t require any maintenance besides a yearly power wash, the cost of the materials and installation is virtually the only expense you’ll have with this railing system. If you’re looking for porch, deck, or stair rails that will give you the most bang for your buck, choose vinyl or aluminum railings. Since vinyl rails are so affordable and require little maintenance, they have been booming in popularity in recent years. Aluminum railings are also becoming more popular since they feature many of the benefits of vinyl railings, such as low-maintenance, strength, and corrosion resistance.
