A cable railing adds a modern, sleek look to decks and porches while keeping sightlines open. As a DIYer, you'll handle the installation yourself—just budget for the materials. Use NailIt to estimate your exact materials cost based on railing length and post spacing.
Estimated DIY materials cost for total materials for typical 40-ft railing — you supply the labor. Prices vary by region and brand.
A handy DIYer can usually take this on; if it needs permits or systems you are unsure about, get a pro quote first. The pro figure is a rough rule of thumb (labor on jobs like this often runs 1–2.5× the materials) — always get real quotes. It is not a NailIt estimate.
NailIt estimates materials only, so here is the honest version of the labour question rather than a number we cannot stand behind. Installed, this job commonly lands somewhere around $1,600–$8,750 — that is the materials range above with labour applied at the rough 1–2.5× multiplier trades typically work to on jobs like this. It is a sanity check for reading a quote, not a NailIt estimate and not a substitute for a real one.
What actually moves that number: your region and local labour rates, access and prep work, whether a permit and inspection are involved, disposal of the old material, and how much the crew has to work around your schedule. For this project the DIY route is realistic for most homeowners, and the labour saving is the whole point. Always collect three written quotes from licensed, insured contractors and compare what each one includes — how we handle pricing.

You'll need stainless steel cable, post brackets or sleeves, tensioners and turnbuckles, lumber for posts, lag bolts, and fasteners. All costs shown are materials only—no labor or contractor fees.
Longer railings need more cable and additional tensioning hardware. A 20-ft deck railing will typically run $400–$800, while a 60-ft wraparound could reach $2,000–$3,500. NailIt adjusts cost based on your exact measurements.
Most jurisdictions require permits for deck railings to ensure code compliance (typically 36–42 in. height, 4-inch sphere rule). Check local codes before ordering materials; permit costs are separate from your materials budget.
