Quick Answer
A broken cupboard door is usually one of three issues: pulled-out hinge (repair with toothpicks and wood glue or move the hinge slightly), cracked panel (clamp with wood glue or replace), or warped frame (humidity damage, allow to dry then adjust the cabinet anchor screws). For European concealed hinges, use the three adjustment screws to fine-tune the door position.

Save to PinterestA broken cupboard door, whether it’s sagging, won’t close, or has come off entirely, makes a kitchen or storage area look tired and can be a daily frustration. Fortunately, most cupboard door problems trace back to the hinges or fixings and are quick, inexpensive fixes you can handle yourself in minutes.
This guide covers how to diagnose and fix the most common cupboard door issues, from loose hinges and stripped screws to misaligned or damaged doors, so everything hangs straight and closes cleanly again.
Why Cupboard Doors Break or Sag
Cupboard doors are opened countless times, so wear is inevitable. The usual causes are:
- Loose hinge screws: Constant use gradually works the screws loose, the most common reason a door sags or won’t shut.
- Stripped screw holes: In chipboard or softwood, the holes wear out so screws spin without gripping.
- Misaligned hinges: Concealed cup hinges drift out of adjustment, throwing the door off square.
- Worn or broken hinges: Cheap or old hinges can bend or fail, leaving the door hanging awkwardly.
Tools and Materials You Will Need
- Screwdriver (Phillips)
- Replacement hinges (if needed)
- Wooden toothpicks or matchsticks and wood glue
- Drill (optional)
- Spirit level
Step-by-Step: How to Fix a Cupboard Door
Step 1: Tighten Every Hinge Screw
Start simple: tighten all the screws on both hinges. Many sagging or sticking doors are completely fixed at this first step.
Step 2: Repair Stripped Screw Holes
If a screw turns without tightening, dip wooden toothpicks in wood glue, push them into the hole, snap them flush, let the glue set, then drive the screw into the fresh wood.
Step 3: Adjust Concealed Hinges
Modern cup hinges have small adjustment screws that move the door up, down, in, out, and sideways. Make tiny turns until the door sits square and aligns with its neighbors.
Step 4: Replace a Damaged Hinge
If a hinge is bent or broken, unscrew it from both the door and the cabinet, match a new one at the store, and screw it into the existing holes.
Step 5: Check and Close
Open and close the door several times, checking that it sits flush, lines up with adjacent doors, and latches cleanly. Fine-tune the adjustment screws if needed.
Pro Tips to Prevent This Problem
- Tighten cupboard hinge screws once or twice a year to prevent sagging.
- Upgrade to soft-close hinges for a quieter, longer-lasting result when replacing.
- Keep spare matching hinges if you have many identical cupboards.
When to Call a Professional
Cupboard door fixes rarely need a professional. Call a cabinetmaker only if the cabinet frame is split, the door panel itself is badly damaged, or you need custom hardware matched and fitted precisely.
Frequently Asked Questions
Why won’t my cupboard door close properly?
Usually loose screws or a hinge that needs adjusting inward. Tighten the screws and make a small in-out adjustment on concealed hinges to fix it.
How do I fix a cupboard door that keeps dropping?
The hinge screws are loose or the screw holes are stripped. Tighten them, or use the toothpick-and-glue trick to give the screws fresh wood to bite into.
Can I just replace one hinge?
You can, but replacing both as a pair keeps the door aligned and wearing evenly, giving a more reliable result.
Final Thoughts
A broken or sagging cupboard door is one of the easiest home repairs there is. Begin by tightening the hinge screws, repair any stripped holes, and use the adjustment screws to square the door, replacing the hinges only if they are truly worn. With a few minutes of work, every cupboard door in your home can hang straight and close perfectly again.
Why Cupboard Doors Fail
Cupboard doors usually fail because the hinge screws loosen, the particleboard around the screw holes crumbles, the hinge cup shifts or the door has been pulled out of alignment over time. The visible problem is a sagging or crooked door, but the repair depends on which part has lost its hold.
Open the door slowly and watch the hinge side. If the whole hinge moves, the screws or mounting plate need repair. If the hinge stays firm but the door sits crooked, use the adjustment screws on the hinge. If the panel itself is cracked, glue and clamping may work only if the crack is clean and the material still has strength.
Repair Before Replacing
A loose hinge can often be fixed with longer screws, wood glue and toothpicks, a dowel repair or a hinge repair plate. Replacing the whole door should be the last step unless the panel is swollen, split or badly warped from moisture.
How to Prevent It Happening Again
Do not overload door-mounted racks, avoid slamming cupboard doors and tighten hinge screws as soon as movement appears. Small movement gets worse quickly because every open and close action widens the screw holes.
