How Much Does It Cost to Replace a Newel Post?

A newel post is the big post at the bottom of a staircase, and at landings and balcony corners, that anchors the handrail. Replacing one costs about $50 to $300 for the post itself, plus $10 to $70 for mounting hardware. Labor to have an installer replace one newel post runs about $250, since it’s a small job.

What Is a Newel Post?

The newel post is the main post that holds up the handrail. Some people call it a stair post or banister post. It’s often spelled “knoll post” or “nule post” too. There are three kinds, based on where they go:

• Starting newel: at the bottom of the stairs. Takes the most force, so it needs the strongest anchor.
• Landing newel: where the stairs turn at a landing.
• Balcony newel: at corners and ends of a balcony or overlook railing.

Can You Replace Just One Newel Post?

Yes. You can replace one newel without touching the rest of the railing. The handrail comes off the old post, the new post gets anchored, and the handrail goes back on with a rail bolt. The hard part is matching the old post’s height and the handrail angle. See how to attach a handrail to a newel post.

A wobbly newel is the most common reason to replace one. Sometimes it can be re-anchored instead of replaced. See how they’re anchored in how to install a wood newel post and how to install iron newel posts.

Replacing the Whole Railing?
