Restore Old Doors
Over the years we replaced a few doors on the main floor with off-the-shelf, 6-panel doors and we had a few old, flat slab doors remaining that needed to be swapped out as well. Most of the doors downstairs are from a 20-30 year old renovation so they were ugly, boring and of poor-quality. They had to go.
Remove the Old Hardware
To get started on the restoration of this old door we need to remove the old lockset. This one came out pretty easy but as you can see, I had break away layers of paint and wrestle a couple stripped screws out. It’s okay to pry some of the stripped screws out like a nail, we’re going to patch that all up in the process.
Remove the Heavily Damaged Areas
Next we’re going to identify and mark the damaged area that needs to be removed. The key to this step is staying parallel and square with the existing edges. This will make it easier to create our patch later. Using an oscillating saw, remove the damaged area.
Drill Bore Holes
In order to fit a new, modern style knob set into this door we need to layout the position of the new lock and cut a new main bore hole and make any adjustments to latch hole. Using a door lock installation jig a great idea here to save time and ensure accuracy.
Make a Patch
Now, it’s time to measure and cut our wood patch. I used a piece of pine cut from a regular 2×4 because pine is easy to work with. The downside with pine is that it’s soft and may damage again easily but with a patch this small and a quality paint to cover it, I wasn’t too concerned.
Fill and Sand
Now we can finish the fit by adding wood filler to all the gaps around your patch. This is a good time fill any other gaps, screw holes or cracks on other areas of the door like the one we saw above. Sand down any high spots around your patch and rough areas on the entire door.
Restore Old Doors
Restoring old doors creates so many great design opportunities and they are fun to hunt for, too. You can update the hardware like we did here or close up all the holes and install the door using sliding barn door hardware. You could even clean one up and just lean it against the wall as decor.
