How to Replace Kitchen Cabinet Hinges: Step-by-Step
Saggy, squeaky, or misaligned cupboard doors can make an otherwise functional kitchen feel tired and worn out. Fortunately, replacing kitchen cabinet hinges is one of the most cost-effective DIY upgrades you can undertake. Whether you are swapping out broken components or upgrading standard hardware to modern soft-close mechanisms, this guide walks you through the entire process from measurement to final alignment.
Choosing the Correct Replacement Hinges
Before unscrewing any fittings, you must determine the type of hinge currently fitted to your units. Standard UK cabinetry typically uses concealed hinges (often referred to as European or cup hinges), but they vary across several key dimensions:
- Cup diameter: The industry standard is 35 mm, though some compact or specialist doors use 26 mm or 40 mm cups. Measure the existing recessed hole on the back of your door.
- Door overlay: Full overlay doors cover the entire cabinet carcass edge, half overlay (twin) doors share a single central partition, and inset doors sit completely flush inside the cabinet frame.
- Crank height and plate thickness: Ensure the hinge arm profile matches your overlay requirements so the door closes squarely against the carcass.
- Hole spacing: Measure the distance between the two screw holes on the hinge cup (commonly 45 mm, 48 mm, or 52 mm centre-to-centre) to avoid drilling fresh pilot holes into the door.
Tools and Materials Required
Gather your tools before starting to make the job quick and straightforward:
- Pozi-drive screwdriver (a manual screwdriver is best for final adjustments to prevent stripping threads)
- Cordless drill with a pilot bit (if new fixing holes are required)
- Tape measure or digital calliper
- 35 mm Forstner bit (only needed if drilling new cup recesses)
- Pencil and masking tape
- Small wooden dowels or matchsticks with wood glue (for repairing worn screw holes)
Step-by-Step Replacement Guide
1. Remove the Old Cupboard Door
Never attempt to unscrew hinges while the door is hanging unsupported. Support the bottom of the door with a wedge or have a second person hold it steady. Unscrew the hinge mounting plates from the cabinet carcass first, starting with the bottom hinge and moving to the top. Carefully lift the door away and lay it flat on a clean, soft work surface.
2. Detach Old Hardware and Inspect Screw Holes
Unscrew the hinge cups from the door. Check the timber or MDF around the screw holes. If the wood has stripped or become loose over years of use, dip wooden toothpicks or dowels into PVA wood glue, tap them into the holes, let them dry, and trim them flush. This gives the new screws a firm, solid grip.
3. Fit the New Hinge Cups to the Door
Insert the new hinge cups into the round recesses on the back of the door. Use a straight edge or ruler across the backs of both hinge bodies to ensure they sit perfectly parallel to the edge of the door. Drive the fixing screws in firmly, taking care not to overtighten and strip the cabinet material.
4. Mount the Base Plates to the Carcass
When selecting hinges for kitchen cabinets replacing older systems, check whether the new mounting plates match the existing 32 mm system screw holes inside the unit. If they line up, screw the new plates into place. If not, mark the correct positions using the plate as a template, drill shallow pilot holes (taking care not to drill through the cabinet side), and secure the plates.
5. Hang the Door and Align
With clip-on hinges, hook the front of the hinge arm onto the mounting plate and press firmly until you hear a distinct click. If using slide-on hinges, slide the arm over the mounting plate screw and tighten it down lightly.
Adjusting and Aligning Your Cabinet Doors
Modern concealed hinges offer three-way adjustment via integrated screws on the hinge arm:
| Adjustment Direction | Function | How to Adjust |
|---|---|---|
| Side-to-Side (Lateral) | Corrects gaps between doors and squares the door with the carcass. | Turn the front screw on the hinge arm clockwise or anti-clockwise. |
| Height (Vertical) | Raises or lowers the door to level it with adjacent units. | Loosen the top and bottom screws on the mounting plate, slide the door, and re-tighten. |
| Depth | Controls how close the door sits against the cabinet face. | Turn or loosen the rear screw on the hinge arm to move the door in or out. |
Frequently Asked Questions
Can I put soft-close hinges on old kitchen cabinets?
Yes. As long as your doors use standard 35 mm cup recesses and match the overlay profile (full overlay, half overlay, or inset), you can replace standard hinges with soft-close alternatives directly.
Do I need to replace the mounting plates when changing hinges?
It is strongly recommended. Even if old plates look identical, minor variations in clip mechanisms and screw offsets between different hinge designs can prevent the door from latching securely.
