Details…

How to Repair Hollow Core Door HolesSo, this is the door that I am using to demonstrate with today. It is one of my pantry doors and has one of those hinge pin door stops. You probably have a few of these around your house as well.

imagesInitially, these were thought to be great alternatives to the spring version that mounts on the baseboards. They look nice and they are out of the way. But there is one big problem with these. They tend to put holes in hollow core doors.

Why? Well, the part that connects with the door does so on the hollow part. If it connected with the solid frame on the edge of the door, there wouldn’t be an issue. Unfortunately, many of us learn this lesson after it is too late. But not to worry, we can fix those ugly holes very easily.

Step 1 – Remove any loose pieces from around the hole. Use your utility knife if needed.

Step 2 – Stuff some paper towels down inside the hole. This will provide a ledge of sorts for the foam insulation to sit until it is dry. Otherwise, the foam would just fall to the bottom of the door.

Step 3 – Fill the hole with the foam insulation,* making sure to fill completely on as sides of the hole. Allow this to dry overnight.

Step 4 – Using a blade or your utility knife, remove the excess dried foam.

Step 5 – Carefully cut back the dried foam until a slight recessed area is left to allow space for the Bondo.

Step 6 – Mix the Bondo* using about a teaspoon amount of bondo with 2″ of hardener.

FYI: This is the Bondo* that I used. Just to let you know, this stuff has a pretty stronge smell. If you are working in a closed room, open a window to allow the smell to ventilate. If you are going to be working in an open area, you may want to weigh the benefits of using Bondo with the smell. If you don’t want to deal with the smell, I would suggest using spackle. However, in my experience the Bondo gives a stronger result.

Step 7 – Smooth bondo over the hole area. This will set up very quickly, so be prepared. (By the way, I am just using a popsicle stick for this)

Step 8 – Wait a few minutes (until the bondo begins to thicken). Then, use the putty knife to scrap the excess bondo away.

Step 9 – Sand the Bondo down as smooth as possible. Don’t worry about getting the pitted areas smooth, yet. Just make sure that it is all flush with the door.How to Repair Hollow Core Door Holes
Step 10 – Mix a small amount of bondo and smooth it over the pitted areas. (Just like icing a cake). Allow this to dry completely. That should take a couple of hours.

Step 11 – Sand (using the fine grit sanding block) until it is completely smooth and flush with the door. (Tip: The sanding blocks will help to get a better/flush result than the sandpaper will).

Final Thoughts…

How to Repair Hollow Core Door Holes

(Farinelli Construction Inc)

The best hinges for hollow core doors are still the base molding spring stops, (as seen on the door in this foreground) and not the hinge pin stops (as seen on the two doors in the background).
Now, if the hole in your door was caused by a hinge pin stop, replace it with a different type.

If the location of the door prevents another type being used, the best solution is to place additional hinge pin stops on the remaining hinges as well. That way the pressure can be distributed among all three or four hinges instead of focusing on just one spot. (Notice that the two doors in this image have hinge pin stops on both the top and bottom hinges).
