Misaligned kitchen and wardrobe cabinet doors singapore households live with are one of the most common and most fixable annoyances in the home. A door that droops, rubs its neighbour or refuses to sit flush is rarely broken. In most cases the hinge simply needs a small turn of a screwdriver. Modern flats and condos almost all use concealed hinges, also called European or cup hinges, which are designed to be adjusted in three directions. This practical, brand-neutral guide shows you how to read a sagging door, make the right adjustment, and recognise the point where a hinge or panel genuinely needs replacing.
Why Cabinet Doors Sag in the First Place
Doors slip out of line for ordinary reasons. Daily opening and closing gradually loosens the mounting screws. Heavier doors, such as tall pantry or wardrobe fronts, put constant downward pull on their hinges. Our humid climate does not help either, as timber and engineered panels swell and shift slightly with moisture, and screw holes in chipboard can enlarge over time. The good news is that concealed hinges were built with all of this in mind, which is why they carry two or three adjustment screws each.
Before touching anything, open the door and look at the gap around it. Note whether the door sits too low, leans to one side, catches its neighbour, or stands proud of the frame. Diagnosing the exact fault first saves you from turning the wrong screw and making things worse.
Understanding the Three Adjustments
Each concealed hinge typically offers three separate adjustments, and knowing which screw does what is the whole skill. Work on one door at a time and turn screws in small amounts, roughly a quarter turn, then close the door and check before turning more.
Side adjustment moves the door left or right and is the one you will use most to fix a door that rubs its neighbour or leaves an uneven vertical gap. It is usually the screw nearest the door, closest to the cup. Depth adjustment moves the door closer to or further from the cabinet frame, correcting a door that sits proud or too deep. This is often the rear screw, which may sit in a slotted hole. Height adjustment raises or lowers the whole door and is not on the hinge itself but on the mounting plate fixed to the cabinet, where a screw in a vertical slot lets the door slide up or down.
| Problem you see | Adjustment to use | Rough action |
|---|---|---|
| Door leans, uneven side gap | Side screw (near cup) | Quarter turns until vertical |
| Door sits too low or too high | Height slot on mounting plate | Loosen, slide, retighten |
| Door proud or too deep | Depth screw (rear) | Turn in or out slightly |
| Door catches its neighbour | Side screw on both doors | Balance the gap between them |
A magnetic Phillips screwdriver is ideal, since it stops the screw dropping into the cabinet. Loosen the mounting plate screws only enough to let the door move, then retighten firmly once aligned.
Step by Step: Realigning a Drooping Door
Start with a door that has dropped at the outer corner, the classic sag. First, tighten every mounting screw on both hinges, as a loose plate alone can cause the droop. If the door is still low, loosen the height screws on the mounting plates a little, lift the door level, and retighten. Next, deal with any sideways lean using the side screw on the top or bottom hinge: turning the top hinge tilts the bottom of the door outward, and turning the bottom hinge tilts the top, so adjust the hinge diagonally opposite the gap you want to close. Finally, even out the front face with the depth screws so the door sits flush with its neighbours. Close the door after each small change and view the gaps at eye level. Patience beats force every time.
For a pair of doors that meet in the middle, treat the gap between them as your reference line and share the correction across both, rather than pushing one door all the way over.
When a Screw Hole Has Worn Loose
Sometimes a hinge feels tight but the door still sags because the screws no longer bite into the chipboard or MDF. A classic sign is a hinge plate that wobbles or a screw that spins without gripping. The simple fix is to give the screw fresh material to hold. Remove the screw, dab a little wood glue onto a few wooden matchsticks or a short length of dowel, tap them into the worn hole, let it set, then trim flush and drive the screw back in. Alternatively, move to a slightly longer or thicker screw if the hinge allows. Avoid overtightening, which strips the hole all over again.
When to Replace the Hinge or Panel
Adjustment has limits, and it helps to know them. Replace the hinge itself when the metal arm is bent, the cup is cracked, the spring no longer holds the door closed, or the hinge is visibly rusted from years of humidity. Concealed hinges are sold by their cup diameter, most commonly 35mm, and by their opening angle and overlay, so take the old hinge to the shop or measure the cup carefully to match a replacement. Swapping like for like is straightforward, as the new hinge drops into the same cup hole and plate position.
Replace or repair the door panel, not just the hinge, when the board around the cup has crumbled, the laminate is delaminating and swelling from water damage under a sink, or the panel has warped so badly that no amount of adjustment brings it flat. A swollen, soft or bubbling panel near a wet zone will keep failing, and refacing or replacing that single door is the honest fix.
Keeping Doors Aligned Longer
A little prevention goes a long way in our climate. Wipe up splashes under the sink promptly, as trapped moisture is the main enemy of chipboard doors. Do not hang tea towels or heavy bags on cabinet doors, since the extra load drags hinges down over months. Every few months, give the mounting screws a quick nip up with a screwdriver before they loosen fully. Soft-close hinges also reduce the slamming that shakes screws loose, and many standard hinges accept a clip-on soft-close damper if you want to upgrade gently.
With nothing more than a screwdriver and a careful eye, most sagging doors are a ten-minute job. Reserve the toolbox for the genuine replacements, and your cabinets will open true for years.
