How to Replace Wooden Balusters with Iron the Easy and Cheap Way!

Here’s how to replace wood balusters with iron and update stair railing without replacing it completely!

Want to update your staircase? Here is our tutorial on how to replace wooden balusters with iron the easy and cheap way!

Talk about a transformation from ’90s to modern! Updating our railing and balusters has been one of the easiest and biggest transformations to move our house away from 1993 to 2017.

We updated our stairwell railings by sanding down the orange-tinted oak railings and staining them with Minwax Dark Walnut.

Then we replaced our stair spindles from white wood balusters to new iron ones and it’s a totally different room!

How to remove wooden spindles

The first thing we did replacing our stair spindles was remove all of our old white wood balusters.

Using our awesome RYOBI One+ Cordless Reciprocating Saw, we cut an angled slice through each baluster and twisted them until they popped off.

The railing spindles were nailed in with a brad nailer, so we had to wiggle them until the nail came loose.

Then, we used an orbital sander to buff down the old orange-tinted oak finish on the railings.

We used three sander discs because of the amount of hidden gunk and sealant that was on these things and kept ruining the pads quickly.

We buffed them down all the way and then wiped everything with a damp rag.

The next step was to stain and seal the railings.

Like we said above, we used Minwax Dark Walnut that we have used on a ton of other projects and is basically the same color as our floors downstairs.

This keeps a cohesiveness through the space and looks elegant.

Then we put five coats of matte polycrylic on the whole thing to keep them from getting warn down by people holding the railings.

How to install iron spindles

The last part of replacing stair spindles was that we added our new iron balusters. We ordered them on eBay for a great price.

There were tons of design options, but because the space was so small, we didn’t want to have anything too elaborate. There’s also tons of options on Amazon.

We opted to alternate two designs (a single swirly on one, a basket in between two swirlies on the other) that were fairly simple and wouldn’t be distracting, yet were also elegant.

To add your own iron balusters, you need to cut them to size. Make sure to measure how deep the hole is in the railing, then how far the distance is between the railing and the bottom.

Add those together and cut your balusters from the center of your design to be that length.

For us, it was 30 inches. This is so you can slide the baluster up into the hole at the top, then drop it down to the board at the bottom.

Wondering how to cut iron balusters? We used our RYOBI reciprocating saw to cut the balusters to length.

They were easy to cut using a fine toothed saw blade. We marked the cuts by putting some Frog Tape where the cut should be and then buzzed it down.

Two things to remember when adding the balusters.

First, make sure you put the shoe on before you insert the baluster into the railing or you’ll have to pull it back out.

The other is to use hot glue to hold them in place.

When researching what kind of glue to use for iron balusters, most places say to use epoxy. But, that makes it VERY permanent and is unnecessary.

Put some hot glue onto the end of the baluster, then insert it into the railing hole and adjust it down.

The glue will dry quick so don’t mess around. Then put a little hot glue around the bottom of the railing and drop the shoe down to cover it up.

This is truly a transformation.

The project took a few days because there were several steps that required waiting (staining and sealing). But, it wasn’t difficult.

The cutting and removing of the old balusters took about an hour for our space.

Sanding took an hour and installation of the new balusters took about two hours total.

It was a lot quicker after the first few when we got in a rhythm.

Updating our railing and balusters made the space look incredibly different and so much more modern.

Wondering how much iron balusters cost? Here’s a cost breakdown:

Balusters – $16.66

2 x basket style @ $4.05 = $8.10

2 x single twist  @ $2.30 = $4.60

4 x flat shoe      @ $0.99 = $3.96

Other railing supplies (stain + sealant) had on hand

Iron balusters are also available at hardware stores like Lowes and Home Depot, but we found the best price on eBay.

**Note: this is just the cost for the railing and balusters at the top, since that hallway is what we are making over for the $100 Challenge.

We also updated the downstairs railings since we were already at it, but I didn’t include that in this total. I hope that makes sense!

We wrote a whole post on the cost of replacing wood balusters with iron!

Looked perfect before, I really hate seeing people using resources to replace perfectly functioning things just because they're bored :( I think repainting would have done it better and more professional than GLUEING parts of the stairs (unsure how it affects safety).


Saturday 28th of August 2021

It was functional before, but that doesn't mean it looked perfect to us. We chose to update those railings for a modern look. You don't need to keep a house looking exactly how it looked the day it was built just because it's functional. To each their own!

Want to replace mine too! But I'm afraid there are no holes on the bottom cap to drop the baluster into. It didn't look like your (on the angle) had holes. How did you do the angled balusters?


Wednesday 7th of April 2021

So we started by just gluing them, but a toddler changed that eventually. We ended up drilling very shallow holes for them to sit in and putting the glue in there to stabilize.

About to try this. Did you just use glue to hold it in place? The top hole is so much bigger than the baluster.


Sunday 1st of November 2020

We used hot glue and then later went back and replaced with 2 part epoxy. Epoxy is very strong. Here is exactly what we used -

Did you need to remove the handrail portion or the newels before sanding and staining?


Monday 24th of February 2020

Nope. We sanded in place. If you have any intricate details or curved features, you'll need to just hand sand with flexible paper to get into the grooves.

Hello. Iā€™m interested in doing this project. By code, my spindles need to be no more than 4ā€ apart. If I take out my balusters and replace them with the thinner metal, they are greater than 4ā€ apart. How hard is the process of drilling new shaving holes in the railing and base trim?


Thursday 13th of February 2020

If your balusters are that much larger and you'd need closer spindles, the problem is going to be the holes you already have in there. It is going to be difficult to drill holes that are properly spaced out among the holes you'll already have in place. Seems to me like they would overlap and would offer no support. Your best bet might be to fill all the holes entirely then start over with new holes. New holes aren't necessarily hard, you just need to ensure that they are completely lined up on top and bottom.
