How to Adjust a Cupboard Door That Won’t Sit Flush
Every kitchen I walk into in Newcastle after a couple years of being lived in has at least three cupboard doors that don’t sit right. One’s dropped 4 mm so the door above it scrapes. 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. I had a customer in New Lambton last month convinced she needed her whole kitchen replaced because “every door is wonky.” Turned out she’d been living with the alignment issues for three years and thought that’s how the kitchen was supposed to look. Twenty minutes with a Phillips driver and the kitchen looked brand new. Cheapest cosmetic upgrade she’d ever paid for, she reckoned.
Right, here’s the thing. Once you understand what each of the three screws on a Blum-style 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 knowing which screw is which — 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. Kaboodle, IKEA Metod, Freedom Kitchens, even most custom kitchens built by Aussie cabinet shops — they all use European-style concealed cup hinges. Learn it on one door, you’ve got it on every door in the country.
What you’ll need
- Phillips #2 screwdriver — hand-tool 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
- 3-in-One oil or sewing machine oil (NOT WD-40) for the hinge pivots
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. Easy as.
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. Why does the hinge type matter? The adjustment logic is completely different — old butt hinges have no adjustment, they’re either right at install or they’re not.
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 uneven (top-to-bottom triangle) — door is racked, needs side-to-side on one hinge but not the other
- Door sits proud or hits the cabinet face — depth adjustment needed
- Whole door shifted toward the hinge or handle — side-to-side on both hinges
Diagnose before you adjust. Otherwise you’ll chase your tail for half an hour.
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 door) = side-to-side adjustment. Clockwise moves the door away from the hinge side.
- The middle screw (or slot screw on the plate) = depth adjustment. Clockwise moves the door away from the cabinet face (more proud), anti-clockwise pulls it in.
- The screws on the plate that mount to the cabinet = height adjustment. Loosen, slide the whole hinge up or down on the plate’s slotted holes, 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. Listen mate, write these three positions on a sticky note inside the cabinet door the first time you do it. Saves you re-learning every time.
Step 4: Always adjust the 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 and you’ll have a bigger problem. The reason top-first works: gravity is pulling the door down, so the top hinge is where the load wants to slip. Tighten there first and the door stays where you put it.
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, then have to back off and start again. Patience here saves time.
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. Pretty much same principle as Step 5 — small movements, both hinges in sync.
Step 7: Test the door’s full range
After every adjustment, open the door fully and close it gently. Should swing smoothly through its arc, click closed (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. This is also a good time to check the door alignment works with the rest of the row, because the eye sees the gap between doors as much as it sees the gap within a single door.
Step 8: Adjust the matching neighbour door
In a row of cupboards, the row is what your eye sees. 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.” A 1 mm step between two doors at chest height is visible from across the kitchen, fair dinkum.
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. If you’ve got a few patched plasterboard holes elsewhere from previous repairs, same principle applies — chipboard is forgiving until you over-torque, then it gives up completely.
Step 10: Lubricate and document
One drop of light machine oil (3-in-One or sewing machine oil) at each hinge pivot. NOT WD-40 — it dries out and leaves a sticky residue. A drop per hinge once a year keeps soft-close action smooth and stops squeaks before they start. Wipe excess so it doesn’t drip onto stored crockery. Then make a tiny pencil mark inside the cabinet: “raised top hinge 1 turn 2026-05” or similar. Six months from now when seasonal humidity moves things again, you’ll know what you did and where to start. If you’re working through other cabinet wear at the same time, the techniques crossover with replacing a doorknob or deadlock — both jobs reward small careful adjustments over heavy-handed cranking.
When to call a tradie
If the hinge cup has pulled out of the door (the 35 mm round hole has stripped through the MDF), or the plate has ripped out of the cabinet side — and you’ve already tried the toothpick-and-PVA repair trick — it’s time for a cabinet maker. Heavy doors on aging chipboard sometimes need the door swapped entirely, or a metal repair plate fitted across both screw positions. Cabinet makers will quote $80-150 to repair a single door properly, way cheaper than replacing the kitchen. Same applies if you’re installing floating shelves into MDF cabinets and the brackets won’t hold.
Common screw-ups
- Cup pulled out of the door. 35 mm hole stripped. Pack with toothpicks and Selleys Aquadhere PVA, dry overnight, re-screw.
- Plate ripped out of cabinet side. Particle board failure. Same toothpick fix or move plate 20 mm to fresh material.
- Door drops every few months. Hinge fatigued — common on heavy doors after 8-10 years. Replacement clip-on hinges are $4-8 from Bunnings.
- Door springs back open. Soft-close failed internally. Replace the hinge.
- Whole row out after a hot summer. Particle board moisture movement. Make seasonal adjustments part of maintenance — five minutes twice a year keeps the kitchen tight.
Cost & time
Hinge replacement clip-ons are $4-8 each at Bunnings or Mitre 10. A drop of oil is essentially free. Time: 30 seconds per door for an existing hinge adjustment, 5 minutes per door for a full hinge swap. Whole kitchen of 20 doors in 30 minutes if everything just needs adjusting.
The Mick wrap
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. Easy as, once you know which screw is which. Don’t be that bloke who replaces a kitchen because nobody told him about the three screws.
