Cable railings cost $150 to $285 per linear foot for a metal post system that includes posts, handrails, wire cables, and hardware with installation. A wood post system is far more affordable at $75 to $95 per linear foot installed. In addition to the type of material, other factors such as the deck size, number of corners, and the height of the railing can impact the overall cost.
While cable railings can be more expensive than other deck railing options, their modern look, low maintenance, and preserved view make them a popular choice for many homeowners.
