How Much Does It Cost to Replace a Banister and Spindles?

Replacing a stair banister and spindles costs about $1,600 to $4,600 installed by a pro, with most jobs landing around $2,600. If you do it yourself, the parts for a typical straight staircase run about $525 to $850 for a new handrail, iron balusters and a newel post. Just swapping old wood spindles for iron, and keeping your handrail, can cost as little as $200 to $400 in parts.

What “Replacing the Banister” Actually Includes

People use “banister” two ways. Sometimes they mean just the handrail you hold onto. More often they mean the whole railing: the handrail, the balusters (spindles) under it, and the newel posts at the ends. The price changes a lot depending on which one you mean, so figure that out before you get quotes. Not sure what each part is called? See our parts of a staircase guide.

DIY Parts Cost: 3 Common Projects

These are real prices from our store as of October 2026, for a typical straight staircase with 13 treads, about 15 feet of handrail (you’d buy a 16 ft rail and cut it to fit) and 3 balusters per tread (39 balusters). Your count will depend on your stairs. Use our baluster spacing guide to get yours.

Project	What you buy	Parts cost
Swap wood spindles for iron	39 iron balusters, 39 base shoes, epoxy	$200 – $400
New handrail only	16 ft red oak handrail, fittings, hardware	$220 – $300
Full banister and spindles	Handrail, 39 iron balusters, shoes, epoxy, 1 newel post	$525 – $850

Iron balusters

Simple twist and knuckle styles from our Twist & Basket and Versatile lines start under $2 each, and our exclusive collections like Wentworth, Heights and Linéa run more. Base shoes cost about $2 to $5 each, and you’ll need epoxy to set them. Our EPC-410 epoxy tubes are $24.20 each, plus the $71.83 gun if you don’t own one. Shop all iron balusters.

Handrail

A 16 ft red oak 6210 handrail is $184.59. Fittings like a start easing or an opening cap add about $15 to $35 each. Other wood species cost more: poplar, hard maple and white oak run about $525 to $1,420 for the same 16 ft rail, and walnut is over $2,000.

Newel posts

A red oak 4191 box newel is about $151. An iron newel is cheaper: the 16.5.8-T plain square bar newel is $49.49, plus $22 to $68 for a mounting kit and $42.68 for a can of EPC-7 epoxy. For a deeper look, see the cost to replace a single newel post.

Professional Installation Cost

According to HomeAdvisor’s 2025 data, installing a wrought iron stair railing averages about $2,600, with most jobs between $1,600 and $4,600. Labor runs about $65 to $100 an hour. Iron balusters with a wood handrail, which is what most of our customers buy, usually fall on the lower end of that range.

Labor is usually the biggest part of the bill. For a full breakdown, read the labor cost of installing a new banister system.

What Makes the Price Go Up

• Length and turns. Landings, balconies and turns add handrail, fittings and labor.
• Wood species. Red oak is the most affordable stain-grade rail. Walnut, cherry and white oak cost a lot more.
• Baluster style. Plain bars are cheapest. Baskets, knuckles, scrolls and hammered styles cost more.
• Curved stairs. A curved rail needs bending handrail, which costs about 3 times more than straight rail.
• Removing the old railing. Pulling out old spindles and posts takes time, and sometimes the treads need patching.
• Your area. Labor rates vary a lot from one city to the next.

How to Save Money

• Keep what’s still good. If your handrail and newels are solid, just swap the spindles. That’s the biggest bang for the buck.
• Do the balusters yourself. Swapping spindles is a weekend project for most handy homeowners. See how to install iron balusters and how to drill the holes.
• Buy the parts yourself. Even if you hire an installer, buying your own parts can save the contractor markup.
• Use a coupon. Check our current coupon codes before you order.

Bottom Line

Plan on about $2,600 to have a pro replace your banister and spindles, or $525 to $850 in parts to do it yourself. If you only want a new look and your handrail is in good shape, swapping to iron balusters is the cheapest way to get it. Questions about your stairs?
