Railings are a safety system
A railing has to hold a person who stumbles into it. Looks come second. Its strength depends on how the posts are attached to the deck frame. Posts that are only notched and nailed to the outside of a rim joist tend to loosen. Builders today use through-bolts, blocking and tested post connectors. When you replace a railing, ask how the posts will be fastened to the frame.
Railing styles
Wood railings are the least expensive and can be painted or stained to match the house. Composite and vinyl systems come as kits with posts, rails and balusters in matching colors and need little upkeep. Aluminum is slim and strong. Cable railings keep the view open, which suits decks looking toward the Hudson, but need tensioning. Glass panels give the clearest view and cost the most.
- Wood: lowest cost, needs paint or stain
- Composite or vinyl: matched kits, low upkeep
- Aluminum: slim and strong
- Cable: open view, needs tensioning
- Glass: clearest view, highest cost
Stairs on sloped lots
On a hillside lot, deck stairs can be long, and long stairs need intermediate landings, solid stringers and a firm base at the bottom. A concrete pad or set stone at the foot keeps stringers off wet soil. Stairs with more than a few risers need a graspable handrail. Consistent riser heights matter more than people expect. Uneven steps cause trips.
Lighting
Low-voltage post cap lights, riser lights on stairs and lights under the rail cap make a deck safer after dark. They are easiest to add while railings and stairs are being built. Trusted Local Contractors puts deck lighting at about $500 to $2,000 in Westchester.
Code details your builder will handle
Railing height, baluster spacing, stair rise and run and handrail shape are all set by code. Your builder should know the current requirements and build to them. If you are replacing railings on an older deck, the new ones generally need to meet current code, which may differ from what was there.
Request an estimate
Gates belong on the list if you have small children or a dog. A self-closing, self-latching gate at the top of deck stairs is a simple safety step, and it is easiest to plan when the railing is designed.
Use the estimate form and choose railings and stairs. Tell us the length of railing, the number of steps and the style you like. A local builder will reach out to measure and price it.
