There is nothing quite like the frustration of a door that refuses to close. You push, you jiggling handle, you grunt. The bottom drags on the floor, the top scrapes the frame, or the side wedges tight when you try to latch it. Most people call a locksmith. Some call a carpenter. The call goes out to emergency services. Meanwhile, the problem is usually just a little humidity, a few warped hinges, or a floorboard that decided to have an opinion.
This isn’t a job for power tools. You don’t need a circular saw. You don’t need a table saw. You need a hand plane, a chisel, and about twenty minutes of patience. If you’ve ever stared at a jammed interior door wondering how to fix a sticking door without replacing it, this is the way.
Why Doors Stick in the First Place
Before you start cutting wood, understand the enemy. Doors stick for three main reasons:
- Humidity changes. Wood expands when it’s wet and shrinks when it’s dry. In the summer, your doors might swell against the frame.
- Sagging hinges. Over time, the screws loosen. The weight of the door pulls the top hinge down, causing the bottom corner to drag on the threshold.
- Installation errors. The door might have been hung slightly out of square from the start.
Identify which one you’re dealing with. Hold a business card against the door frame. Slide it into the gap between the door and the frame. Move around the perimeter. Where the card won’t fit? That’s your contact point. Mark it with a pencil. If the card fits everywhere but the door still won’t latch, the problem might be the strike plate, not the wood.
The Tools You Actually Need
You don’t need a workshop. You need a basement, a garage, or a clear patch of driveway. Here’s the kit:
- Block plane. A smaller, lighter version of a hand plane. Easier to control.
- Chisel. For cleaning up hinge mortises.
- Sandpaper. Coarse grit to start, fine grit to finish.
- Pencil and ruler. For marking lines.
- Masking tape. To protect the finish while you plane.
- Screwdriver. For tightening or replacing hinge screws.
Safety first. Eye protection is non-negotiable. Shavings fly fast. They don’t care about your corneas.
Step 1: Tighten the Hinges
Start simple. Often, the door sags because the screws are loose. Pull the door open wide. Look at the hinges. Are the screws stripped? Are they wiggling?
Tighten them. If they spin freely, the screw holes are stripped. Fill them with wooden matches or toothpicks dipped in wood glue. Let it dry. Reinsert the screws. Tighten again. Sometimes, that’s it. You’re done. Go drink a beer.
If the door still drags, move to step two.
Step 2: Plane the Bottom Edge
If the bottom corner is dragging on the floor, you need
