How to Repair a Broken Kitchen Cabinet Hinge

August 25, 2026

A sagging, loose, or completely detached cupboard door is one of the most common issues in any busy kitchen. Because cabinet doors are opened and closed dozens of times a day, the hardware takes continuous strain. In most cases, you do not need to replace the entire carcass or door to resolve the problem. With a few basic tools and the correct hardware fittings, you can quickly repair kitchen cabinet hinge faults and restore your cabinetry to smooth, reliable working order.

Diagnosing the Cabinet Hinge Problem

Before reaching for replacement hardware, inspect the fitting closely to determine why the hinge is failing. Most issues fall into one of three categories:

Loose fixing screws: The screws have worked themselves loose from the chipboard or MDF carcass.
Stripped or blown-out screw holes: The wood fibres inside the screw holes have crumbled, meaning the screws no longer grip.
Mechanical wear or internal failure: The hinge arm, spring mechanism, or soft-close piston is bent, cracked, or broken.

Fixing Stripped Screw Holes with Hinge Repair Plates

Standard kitchen cabinets are typically manufactured from melamine-faced chipboard (MFC). Over time, repeated leverage can pull fixing screws straight out of the cabinet wall, leaving an enlarged hole that standard wood screws cannot grip.

Using Stainless Steel Repair Plates

The most robust and permanent method to fix blown-out mounting points is installing a hinge repair plate. These flat, pre-drilled metal plates fit over the damaged area on either the cabinet carcass or the back of the door:

Remove the door by releasing the hinge arm from the mounting plate (using either the quick-release clip or the central securing screw).
Unscrew the damaged mounting plate from the carcass or the hinge cup from the door.
Position the repair plate over the damaged holes, ensuring the central pattern matches your standard 32 mm system spacing.
Secure the repair plate into sound, undamaged timber using several short wood screws around the perimeter.
Fix the original hinge cup or mounting plate directly into the threaded holes provided on the repair plate.

Replacing a Broken Concealed Hinge

If the internal spring has snapped or the hinge arm is distorted, the hardware itself must be replaced. Most modern kitchens utilise concealed (European-style) cup hinges. When selecting a replacement, make sure to measure your existing components accurately:

Cup diameter: The standard industry size is 35 mm, though some compact or specialist cupboards use 26 mm cups.
Door overlay: Identify whether your door is full overlay (covering the entire carcass edge), half overlay (sharing a central divider with an adjacent door), or inset (sitting flush inside the frame).
Opening angle: Standard kitchen cupboards usually require a 95-degree to 110-degree opening angle, whilst corner units often use wide-angle 155-degree or 170-degree hinges.
Mounting plate pattern: Ensure the replacement mounting plates match the screw spacing of your carcass (traditionally 32 mm centres set 37 mm back from the front edge).

Realigning and Adjusting the Cabinet Door

Once your hardware is securely mounted, the door will almost certainly need fine adjustment to sit level and create even gaps around the frame. Concealed hinges feature built-in adjustment screws for three-dimensional alignment:

Side-to-side (Lateral): Turning the front screw on the hinge arm shifts the door left or right to correct vertical gaps between adjacent doors.
Height (Vertical): Loosening the top and bottom screws on the mounting plate allows you to slide the door up or down to align with adjacent drawer fronts.
Depth: The rear screw on the hinge arm moves the door closer to or further away from the cabinet frame, preventing rubbing against the carcass.

Frequently Asked Questions

Can I use standard wood filler to fix stripped hinge screw holes?

Standard filler or wall filler lacks the structural strength to hold load-bearing screws under leverage. If you do not have a metal repair plate, a traditional joinery fix is to drill out the damaged hole, glue in a solid hardwood dowel with PVA adhesive, allow it to cure, and re-drill a fresh pilot hole.

Do I need to replace both hinges if only one is broken?

It is generally recommended to replace both hinges at the same time. Hinges from different manufacturers or production batches often have subtle differences in geometry and spring tension, which can place uneven stress on the door and lead to premature failure.
