Door Not Closing Properly? How to Fix It in Your HDB Flat

Key Takeaways

• A door not closing properly has usually dropped on its hinges. A loose top hinge lets the door sag, so it rubs the frame and the latch misses.
• Find where it rubs before you fix anything. Top corner, bottom edge and latch edge each point to a different cause.
• Don’t plane a door that only sticks in wet weather. Timber swells in humidity and shrinks back, and a planed door can end up gapped.
• HDB says the closer on a fire-rated main door is a safety device that should stay in place.
• Door hinge plate replacement starts from S$75 in Singapore with Urban Company, and hourly handyman bookings start from S$39.

It’s 11pm in your 4-room resale flat in Tampines. The bedroom door scrapes at the top corner, and when you let go it bounces open again, letting the aircon out. A bedroom door not closing is rarely a broken door. Here’s why your door is not closing properly, and which fixes you can do tonight.

Why Is Your Door Not Closing Properly?

Usually because the door has dropped on its hinges. As the top hinge screws loosen, the latch side drops, causing most symptoms below.

Symptom	Likely cause	Fix	DIY?
Rubs at the top corner on the latch side	Top hinge screws loose, door sagging	Tighten top hinge screws	Yes
Hinge screw spins and won’t tighten	Stripped screw hole	Longer screw, or plug and redrill	Yes
Door won’t close, latch clicks against the plate	Latch sits below the strike plate	Fix the sag, then file or move the plate	Yes
Rubs along the latch edge in wet weather	Timber swelling with humidity	Wait, then seal the edge	Yes
Scrapes the floor at the bottom	Sag, or new flooring raised the floor	Fix the sag, or trim the door	Trimming is a handyman job
Hinge bent, cracked or worn	Hinge failed	Replace the hinge	Handyman job
Main door closer won’t pull shut	Closer needs adjustment	Adjust, never remove	Handyman job

If the handle wobbles rather than the door, see our guide to a loose door handle.

Where Is Your Door Rubbing?

Close the door slowly and watch the gap around it. It should be even along the top and latch side. Where it closes up is where the door rubs.

• Door rubbing against frame at the top, latch side: the classic sag.
• Rubbing along the whole latch edge: usually swelling, or layers of paint on the edge and frame.
• Rubbing at the bottom: sag again, or vinyl or new tiles laid over the old floor during a renovation.

How Do You Fix a Door Sagging on Its Hinges?

Tighten the top hinge first. It fixes most cases of door sagging:

1. Wedge a book under the open door’s latch side to take its weight.
2. Tighten every hinge screw on both the door and the frame, top hinge first. Snug, not forced.
3. If a screw spins without gripping, the hole is stripped. Swap in a longer screw that reaches the solid frame behind, or fill the hole with timber sticks and wood glue, let it dry, then drive the screw back in.
4. Close the door and check the gap. Once it’s even, the latch usually catches too.

A bent, cracked or worn hinge needs replacing, not tightening. Our guide to a sagging cabinet door covers the smaller cousin of this job.

Why Is Your Door Not Latching?

Because the latch and the strike plate no longer line up. A door not latching after the sag is fixed needs the plate adjusted:

• Find the miss. Rub chalk or lipstick on the latch, close the door, and see where it marks the plate.
• Off by 1 or 2 millimetres: file the plate opening wider on that side.
• Off by more: unscrew the plate and refit it higher or lower. Fill the old screw holes first.

A latch that sticks or won’t spring out is a handle problem, not alignment.

Does Humidity Make Doors Stick in Singapore?

Yes. Timber and timber-composite doors take in moisture and swell, most often toilet doors and doors with an unpainted edge, and most in the monsoon months. If it only sticks in wet weather, don’t plane it: it may shrink back and leave a gap. Seal bare edges with paint, and plane only if it sticks all year.

Is an HDB Main Door Different?

Yes. Treat the closer as part of the door, not an accessory. HDB’s gate and door care guide says all fire-rated doors at the entrance of HDB flats are installed with a door closer, a safety device that keeps the door shut during a fire. Don’t remove or disconnect it, and don’t plane or cut a fire-rated door. Tightening loose hinge screws is fine.

Replacing it is different. HDB’s building works guidelines cover replacing a main door, internal door or front gate, so check them before you buy.

The steel door on your household shelter has its own rules. SCDF’s guide to shelter types says owners must keep the shelter door operating smoothly and free of rust, and must not tamper with it. If it won’t close, ask your HDB Branch Office first.

Who Pays If the Flat Is New?

HDB, if you report it within the defects liability period. For new flats, HDB’s defects rectification page sets a 1-year defects liability period, with rectification requests made online or at your Building Service Centre. Report it before fixing it yourself.

When Should You Call a Handyman?

Tighten screws, fix a stripped hole and file a strike plate yourself. Call a handyman for a bent or worn hinge, a door that needs planing or trimming, a frame that has moved, or a main door closer that no longer pulls the door shut.

Door hinge plate replacement starts from S$75. An Urban Company handyman arrives within 30 minutes of booking, fully equipped. You may need to supply the hinge or parts. Bookings are by the hour, not by task, from S$39, so 1 visit can also cover a sliding wardrobe door that’s off its track.
