How to Replace and Build a Newell Post

a final Newell Post that is white and had a banister butted into the Newell Post

In this blog post, we will show you each step to replace and build a Newell Post: removing the old post, building the new post (box), attaching to the wall, trimming, caulking, and painting.


We decided it was time to renovate my craft room. My craft room is in our loft. As is typical when updating a room, you quickly realize some other areas or items need to be updated in the process. Replacing the Newell post was not on our initial list when we started our craft room renovation project. It was a 1980s-style Newell post.

Removed Old Newell Post

Below is a picture of the old Newell post. We used a jigsaw to carefully remove the post. In addition, we removed the cedar piece of wood behind the post.

Built New Newell Post

We built a three-sided box. This was built from 1 x 6’s.

Attached to the Wall

Once we removed the old post, we attached a 1×4 to the wall to secure the three-sided box (post) we built to replace it. This 1×4 served as a channel for the 3-sided box.

Trimming the Post

First, we trimmed the top of the box with 3 1/2 inch trim cut at 45 degrees.

Then, we trimmed the bottom of the box with 4 1/2 inch trim also cut at 45-degree angles.

For the the narrow trim, we used 1x2s, 1x4s, and 1x6s. We cut these using our table saw and our miter saw. See the picture below that shows where we added each piece.

Making the Top

We made a cap for the top of the post using a 1×6 with a half-inch overhang on the front and the sides.

Caulking and Painting the Newell Post

Here is a picture of the Newell post after we installed our vinyl plank flooring.

We are so pleased with how this turned out!
