Interior doors are expensive. It really adds up when you have to replace three or four doors! Our upstairs hallway has been completely untouched. Nothing. Nada. Since we moved in. The upstairs as a whole has been largely neglected until earlier this year when we did our first quick Master Bedroom Refresh. But we’re finally sharing another project to improve the look of our upstairs hallway, and it’s a very affordable interior door makeover that I know you all will love!

These are our current hallway doors. The boring, hollow core wooden doors that you’ve probably seen in many homes over the years. These doors were actually originally found at a local Habitat Restore.

My husband’s parents built this house. They did everything as affordably as they could, which meant picking up a lot of second-hand items. They have worked great and served their purpose, but my modern-loving soul was dreaming of an upgrade.

When I started this project, I shared on Instagram, and I honestly did not know if they were going to turn out! But I’m happy to report that I love the end results.

Video Tutorial for our Interior Door Makeover

For all of the visual learners, we made a video tutorial of the entire process. There are a few things that are easier to learn visually than through words, so I hope this make the process clearer.

An Easy Interior Door Makeover

Transforming your doors is as easy as using a circular saw and a paint brush. Anyone could do this transformation, and I mean anyone!

Materials Needed for Door Makeover

How to Cut Your Interior Doors

The hardest part of this entire project is cutting your doors. Honestly, I was a bit terrified to cut them. It’s only a thin wood veneer on top of a hollow core and it’s dangerously thin for someone to be cutting it! But we took is slow and it worked.

I wanted five equal panels, and four cuts separating them. Our door was just about 80 inches tall, so we measured every 16 inches and made a mark, and then drew a line across the door so that we knew exactly where to cut.

Once your thin cuts are made, give everything a very light sand. Just enough sanding to roughen up the surface and allow the paint to adhere. When you’re done, you can turn our door over and make the same cuts on the other side as well if you wish.

We made our very thin cuts (approx. 1/6th of an inch) using a track saw, but you can also use a circular saw with a straight edge, or a 2×4 board clamped to the door to act as a guide for your saw.

How to Paint Your Interior Doors

Painting is the easiest part of this project! Although also the most time consuming, lol. Each side of your doors will require two coats of paint. I used a small foam brush (thank you dollar store!) to get into the grooves that I had made with the saw. Then I used a large roller to paint the fronts and sides.

deep well by Valspar for interior doors

I wanted deep dark doors, so I chose to use Deep Well by Valspar. It’s a very deep, almost black colour with blue undertones. Some lights made it look more navy than others, but in my dark hallway with no natural light, it’s the perfect black for our interior door makeover!

How To Fix Holes on Hollow Interior Doors

We made one tiny error on one of our three doors. The veneer was a bit thinner, and we accidentally cut right through to the hollow core of the door.

fixing interior doors with putty

If you happen to do this as well, we recommend that you fill that gap with a fast-drying putty, and fill the entire line. When it is dry, sand it down and cut a new line with your track saw a couple of millimetres before or after your other line. You don’t want to cut on the same spot again because the putty likely won’t hold up to a new cut.

We did this on one of our doors, and I bet you can’t tell which one! The millimetre or two difference is not even noticeable.

My Doors Don’t Fit When Re-Installing Them

When your doors are finished and painted, it’s time to install them. Installation is fairly straight forward. If you find that your doors are not fitting exactly as they used to, it is likely because of the extra layers of paint. Even a millimetre or two can throw off the alignment of a door.

If that is the case, it is likely just the paint in the way of the hinges that is giving you grief. Take a chisel and chisel out any of the excess paint in the hinge locations, and re-install your door.

This simple transformation completely changed the look of our hallway. I love the new dark doors. The fresh cuts really do look like panels and modernize the space sooooo much!

It was a little harder to photograph and see the lines on these dark doors in our hallway, but in person you can see them beautifully! And when you open the doors and let the natural light pour in on them, they shine!

Since the entire project was FREE, we splurged a bit on some new matte black handles. The old knobs would’ve looked awful on here. I’m so glad I went with these ones because they look amazing!

  1. Hey guys, you are so great! The new door looks very very cool. I also want to have a Makeover for my interior door. But I do not have enough room to do this job… Your new black door is really what I want.

    1. Yes, we used a paint with primer built-in, but honestly, I wish we had primed it first, because it did scratch a bit when we moved it and we had to do touch-ups. Primer would’ve prevented that!
