Heavy wooden doors create stress on their top hinges. In older homes, decades of stress can strip the screw holes, allowing the screws to pull out of the wall and the hinge to come loose. While there are a few solutions which involve wood glue, golf tees, or toothpicks, Nathan’s preferred method is a dowel and epoxy. Here’s the process.
Note: When choosing new screws, do your best to choose screws with a similarly-sized head with the same slot. Larger heads will stick up from the original hinge and make the door hard to close. Sticking with the same slot type will help the repair blend in. Sometimes, the best “new screws” are actually old ones.
How to Repair a Stripped Screw Hole
- Remove the existing screws and pull the hinge leaf from the door. In most cases, it won’t be in the way if you fold it over against the door.
- With a ¼-inch drill bit, drill into the screw holes to make them uniform. Only drill through the jamb. Once there isn’t any more resistance, move to the next hole. Continuing to drill may damage the jack stud behind the wall, preventing longer screws from catching.
- Vacuum the screw holes to remove any saw dust and debris.
- Cut the ¼-inch down into smaller pieces, about an inch long. Mix some two-part epoxy on a scrap piece of cardboard. Roll the ends of the dowels pieces in the epoxy and place them in the screw holes. Let the epoxy harden.
- Once the epoxy has cured, use an oscillating tool to cut the dowels flush with the hinge mortise. Sand as needed.
- Tip the bottom of the door upward to seat the hinge leaf in the mortise. Hold it in place with a door jack or shims.
- Using a self-centering drill bit, place the tip in each of the hinge holes and drill small pilot holes.
- Choose a drill bit with a diameter slightly smaller than the new screws to allow the threads to sink into the jamb material. Drill each of the pilot holes slightly larger with this bit.
- Put a small dab of wax on the ends of the screws and hand-tighten them until the hinge is secure. Align all of the slots on the screws for an extra bit of detail.
Resources
Nathan used a clamp jack to stabilize the door in place while working on it. Drill larger holes in the existing screw holes with a drill and 1/4” drill bit.
Use a quarter inch drill bit to create the pilot holes. Use a self-centering drill bit to drill the hole perfectly centered. Be sure to keep your arm square while drilling.
Use a vacuum to remove sawdust from the holes. Cut dowels to an inch before mixing up the two-part epoxy. Dip the dowel in the epoxy mix and insert into the hole. Allow the epoxy to harden. Use an oscillating tool to cut the dowels flat to the surface. Use 120-grit sandpaper to hand sand the dowels smooth.
Apply wood screw lubricant to the 2-1/2” brass screws to help decrease resistance between the screw tip and wood fibers. Use a screwdriver to screw in the brass screws to avoid stripping.
