How to Adjust a Cupboard Door That Won’t Sit Flush

By Mick — lead handyman, Newcastle NSW.

Every kitchen I walk into in Newcastle, after the place has been lived in a year or two, has at least three cupboard doors that don’t sit right. One’s dropped 4 mm so the door above it scrapes when you open it. One’s leaning toward the fridge so there’s a triangle gap on the hinge side. One won’t close properly because it’s been catching on the bench top. Owners think the kitchen is failing. It’s not. It’s just that nobody’s adjusted the hinges in two years and timber and MDF move with seasonal humidity.

Once you understand what each of the three screws on a Blum (or Hettich, or Hafele) hinge actually does, you can re-align an entire kitchen’s worth of doors in 15 minutes. Three screws. Three axes. That’s it. The hard part is just knowing which screw is which — and most YouTube tutorials get it wrong because they’re filming American Liberty hinges that have different conventions than the Blum-clones every Aussie flat-pack uses.

I had a customer last month convinced she needed her whole kitchen replaced because “every door was wonky”. Turned out she’d been living with the alignment issues for three years and just thought that was how the kitchen was supposed to look. Twenty minutes with a Phillips driver and the kitchen looked brand new. She paid for the call-out and said it was the cheapest cosmetic upgrade she’d ever done.

Kaboodle from Bunnings, IKEA Metod, Freedom Kitchens, even most custom kitchens built by Aussie cabinet shops — they all use European-style clip-on hinges (the technical term is “concealed cup hinge”). The mechanism is essentially a Blum copy. Once you’ve got it on one door, you’ve got it on every door in the country.

What you’ll need

• Phillips #2 screwdriver (PH2) — by hand is better than power for this, the adjustments are tiny
• A second person OR a piece of masking tape to mark before-and-after positions
• Pencil
• Optional: small magnetic torch to see into the cupboard

That’s it. No drills, no replacements, no glue. If your hinge is physically broken (cracked plate, snapped spring), that’s a different article — but adjustment covers 95% of misalignment cases.

Step 1: Identify your hinge type

Open the door and look at the hinge. Two metal parts: the “cup” (sits in the round hole drilled into the door) and the “plate” (screwed to the cabinet side panel). Connecting them is a clip mechanism with three visible adjustment screws. Look for a small button or lever where the cup meets the plate — that’s the clip release. If your hinge looks completely different (two flat plates with three screws on the cabinet face), it’s an old-style butt or surface-mount hinge and this article isn’t for you.

Step 2: Diagnose the misalignment

Close the door and step back. Look at the gap around all four edges:

• Top gap larger than bottom gap — door has dropped, needs height adjustment
• Hinge-side gap is uneven (top-to-bottom triangle) — door is racked, needs side-to-side adjustment on one hinge but not the other
• Door sits proud (sticks out) or hits the cabinet face — depth adjustment needed
• Whole door is shifted toward the hinge or handle — side-to-side on both hinges

Step 3: Learn the three screws (Blum/Hettich layout)

This is the bit US tutorials get backwards. On a Blum-clone hinge:

• The screw closest to the cup (front of the door) = side-to-side adjustment. Turn clockwise to move the door away from the hinge side.
• The middle screw (or the slot screw on the plate) = depth adjustment. Turn clockwise to move the door away from the cabinet face (more proud), anti-clockwise to pull it in.
• The screws on the plate that mount to the cabinet = height adjustment. Loosen them and slide the whole hinge up or down on the plate’s slotted holes, then re-tighten.

Some Hettich Sensys hinges have a separate height cam on the plate — turn it instead of loosening the mounting screws. Look closely; if there’s a single screw with a numbered cam, that’s the height.

Step 4: Always adjust top hinge first for height issues

If the door has dropped, the fix is usually at the top hinge — loosen its plate screws by half a turn, lift the door 2 mm, re-tighten. Then check the bottom hinge isn’t binding. Don’t loosen both hinges at once or the door will fall.

Step 5: Side-to-side: small turns, alternate hinges

For racked doors (triangular gap), turn the side-to-side screw on the hinge that’s on the wide-gap end. Quarter-turn, close the door, check. Quarter-turn, close, check. Don’t crank a full turn — the hinge has limited range and you’ll bottom it out.

Step 6: Depth adjustment for proud doors

If the door is sticking out from the cabinet face more than its neighbour, the depth screw on each hinge needs to come anti-clockwise (pulls the door in toward the cabinet). Do it equally on both hinges or you’ll induce a rack. Quarter-turn each, test, repeat.

Step 7: Test the door’s full range

After every adjustment, open the door fully and close it gently. It should swing smoothly through its arc, click closed at the end (most modern hinges are soft-close), and sit flush. If it now hits the door beside it — you went too far on side-to-side. Back it off.

Step 8: Adjust the matching neighbour door

In a row of cupboards, the eye sees gaps between doors as much as it sees gaps within one door. Once you’ve sorted the dropped door, look at the gap between it and its neighbours. You may need to bring the neighbour up or down 1 mm to make the row look uniform. Your eye is the final judge — what you’re chasing is “the row looks like a row”.

Step 9: Tighten any loose plate screws

While you’ve got the screwdriver out, run it across every plate screw in the kitchen. Particle-board cabinets (which is most of Kaboodle and IKEA) loosen over time, especially around the sink and stove where there’s heat and moisture cycling. Snug, not gorilla-tight — over-tightening strips the chipboard and you’ll be drilling out and re-plugging.

Step 10: Document the adjustments

Bonus tip: after adjustment, lubricate the hinge mechanism with a single drop of light machine oil (3-In-One, sewing machine oil) at the pivot point. Don’t use WD-40 — it dries out and leaves a sticky residue. A drop per hinge once a year keeps the soft-close action smooth and stops squeaks before they start. Wipe excess off with a rag so it doesn’t drip onto stored crockery.

This sounds nerdy but it’s worth it. Write a tiny pencil mark on the inside of each cabinet noting “raised top hinge 1 turn 2026-05” or similar. Six months from now, when seasonal humidity moves the doors again, you’ll know what you did last time and where to start.

Common things that go wrong

What I see when people have tried adjusting and made it worse, or when the hinge is genuinely past adjustment:

• Cup hinge pulled out of the door. The 35 mm cup hole in the door’s MDF has stripped. Fix: pack the hole with a couple of toothpicks and PVA glue (Selleys Aquadhere), let it dry overnight, then re-screw. For a stronger fix use a Mini Fix or Hettich repair plug. Heavy doors really want the door swapped or a metal repair plate fitted across both screw positions.
• Hinge plate ripped out of the cabinet side. Particle board failure — usually around the sink. Same fix with toothpicks and glue, or move the plate up/down 20 mm to fresh material.
• Door drops every few months no matter how often you adjust. The cup hinge is fatigued — common on heavy doors after 8–10 years. Replacement clip-on hinges are $4–8 from Bunnings; just match the cup diameter (35 mm standard, some IKEA use 26 mm) and the opening angle.
• Door won’t stay closed (springs back). Soft-close mechanism inside the hinge has failed. Hinge replacement is the fix — you can’t service the soft-close internally on most Blum-clones.
• Run of doors all out of alignment after a hot summer. Particle board absorbs moisture and the cabinet body itself moves. Make seasonal adjustments part of your maintenance routine — five minutes twice a year keeps a kitchen looking factory-fresh for a decade longer.

The Mick rule

The three screws on a Blum-style hinge each control one axis: side-to-side (closest to the cup), depth (middle), height (the plate mounting screws or cam). Once you’ve internalised that, every misaligned cupboard door in your house is a 30-second job. Don’t watch American hinge tutorials — they’ll send you the wrong way on side-to-side because Liberty hinges are rotated differently.
