A door that won't sit flush, catches on the frame, or swings back open on its own is one of the most common kitchen complaints, and one of the easiest to misdiagnose. Most people either tighten a random screw and hope, or assume the whole door needs replacing when the actual problem is a five-minute hinge adjustment. Here's how to work out what's actually wrong before you do anything.
Start With a Simple Diagnostic Test
Close the door slowly and watch exactly where it stops or catches, this single observation tells you most of what you need to know.
- Catches or rubs on one side of the frame — almost always a hinge alignment issue, the door is sitting slightly forward, back, or to one side of where it should be.
- Bounces back open rather than staying shut — worn hinges, most likely a failing soft-close mechanism or a spring that's lost its tension.
- Rubs along the top or bottom edge — the door has sagged, usually from loose screws rather than a fundamentally broken hinge.
- Won't line up with the door next to it — could be either door, or the shared cabinet frame between them, worth checking both before assuming one is at fault.
The Most Common Cause: Loose Screws, Not Broken Hinges
This is genuinely the number one culprit, and the easiest fix by far. Every time a door opens and closes, there's a tiny bit of stress on the hinge screws, and after thousands of cycles, they work themselves loose enough that the door starts to sag or drift out of alignment. Open the door and check every screw on every hinge, both the door side and the cabinet frame side, and simply tighten anything that's loose with a screwdriver, not a power drill, which can easily overtighten and strip the hole. Often this alone fixes the problem completely.
If the Screw Holes Are Stripped
Particleboard and MDF cabinets are particularly prone to this. If a screw spins without tightening, the hole itself has worn out rather than the screw being the problem. The standard fix is to remove the screw, pack the hole with a sliver of wood dipped in glue (a cocktail stick or matchstick works fine), let it dry fully, then redrive the original screw into the now-solid hole. It's a genuine repair, not a temporary patch, provided the glue's had time to cure properly first.
Concealed Hinges Have Adjustment Screws, Use Them Before Replacing Anything
Most modern kitchen cabinets use concealed (European-style) hinges, which have two or three small adjustment screws built into the hinge itself, controlling depth, height, and side-to-side position. Before assuming a hinge needs replacing, it's worth working through these adjustments:
- Door sits too far forward or back: adjust the depth screw
- Door is higher or lower than the one next to it: adjust the height screw
- Gap is uneven side to side, or the door catches on the frame: adjust the side screw
Turn each screw in small increments and test the door after every adjustment rather than cranking it several turns at once, concealed hinges are precise enough that a millimetre makes a visible difference.
When It's Genuinely Time to Replace the Hinge
Adjustment only fixes alignment, it can't fix a hinge that's mechanically worn out. If you've adjusted everything and the door still won't sit right, or the soft-close action feels weak and unreliable, or there's visible rust, cracking, or metal fatigue on the hinge itself, replacement is the right call rather than continuing to fight it with adjustment screws. This is also a good moment to upgrade to soft close if your current hinges don't have it, most standard hinge replacements are a straightforward swap using the same fixing pattern. Our DTC 110° Hinge covers the standard 35mm cup and 16-22mm door thickness range that fits most UK kitchen cabinets.
What If It's the Door Itself, Not the Hinge?
Wood and MDF respond to humidity, and a door that's cupped, bowed, or twisted won't sit flush no matter how well the hinges are adjusted. Lay a straight edge or ruler across the door's face, if there's a visible gap or curve, the door itself has warped rather than the hinge being at fault. Minor warping sometimes settles back over time in a stable, dry environment, but a badly warped door usually needs replacing rather than repairing, adjustment can't correct a physically bent panel.
Frequently Asked Questions
1. My cabinet door slams shut on its own, what's actually wrong?
This usually points to a worn or failing soft-close mechanism inside the hinge, the spring or damper has lost its tension over time. Adjustment won't fix this, the hinge itself needs replacing.
2. Is it normal for hinges to need tightening every few months?
Occasional tightening is normal maintenance, particularly on well-used doors, but if the same screws keep working loose repeatedly within weeks, the screw holes may already be stripped and need the wood-filler repair rather than just retightening.
3. Can I add soft close to hinges that don't currently have it?
On many standard overlay and concealed hinges, yes, either by replacing the hinge with a soft-close equivalent using the same fixing pattern, or in some cases adding a separate soft-close damper. It's not universal across every hinge type, so check compatibility first.
4. How do I know if my hinges are concealed, surface-mounted, or something else?
Open the door and look at where it attaches to the frame. Concealed hinges are largely hidden inside a round cup drilled into the door, with only a small visible arm. Surface-mounted hinges sit fully exposed on the face of the door and frame.
5. Is it worth repairing an old hinge, or should I just replace it?
If the hinge is mechanically sound and the issue is purely alignment or loose screws, adjustment and minor repair are the sensible route. If there's visible wear, rust, or the soft-close action has failed, replacement is usually cheaper in the long run than repeated repairs.
6. My door is warped, does it need replacing entirely, or can just the door be swapped?
Usually just the door, not the whole cabinet. Provided you know your door's exact size and hinge positions, a warped door can typically be replaced on its own without touching the cabinet carcass underneath.
