A stubborn door is one of the most universal home annoyances, and this door troubleshooting guide exists to turn that frustration into a quick diagnosis. Almost every door fault — a leaf that won’t close, a latch that misses, a squeak that wakes the house, a swollen edge that jams every monsoon — traces back to one of a handful of causes: loose hinges, a misaligned strike, swelling, settlement, or simple wear. Once you can name the cause, the fix is usually cheap and often a weekend job. This page is the master index: find your symptom in the big table below, then jump to the step-by-step spoke that solves it. Where a fault is structural, glass, or powered, we tell you honestly to stop and call a professional.

How to use this door troubleshooting guide

Start with what the door is actually doing, not what you think is wrong. A door that “won’t close” might be rubbing the frame, dragging the floor, sagging on a loose hinge, or simply swollen — four different fixes. Open and shut the door slowly and watch where it touches, where the gap closes, and where the latch lands relative to the strike plate. Run a finger around the gap (the reveal) between leaf and frame: it should be roughly even, about 2–3 mm at the sides and top, 5–10 mm at the bottom. Uneven gaps point straight at the cause.

Not sure where to begin? Our door problem diagnoser walks you through a few yes/no questions and points you to the right repair. To budget first, the door repair cost estimator gives a quick figure before you call anyone.

The five root causes behind almost every door fault

The long list above collapses into a short one. Knowing these five makes you faster at diagnosing anything.

1. Loose or sagging hinges

Gravity and daily use slowly pull hinge screws out of the jamb, especially the top hinge. The leaf drops on the latch side, the top corner rubs, and gaps go tapered. The cure is often just tightening screws — or, if the holes are stripped, the matchstick-and-glue trick or longer screws into the stud. This single cause explains “won’t latch,” “rubs at top,” “drags,” and “uneven gaps” together.

2. Humidity and swelling

India’s monsoon is hard on timber and flush doors. The leaf absorbs moisture, swells along the edge, and jams — then shrinks back in winter. Resist the urge to plane on the first damp day; mark exactly where it binds and only ease that spot. Sealing all six edges with polish or paint is the long-term answer. Check your risk with the door swelling risk checker.

3. Frame movement and settlement

New buildings settle; old frames go out of plumb. That gives a door that swings open by itself, gaps wider at top than bottom, or a latch that no longer meets the strike.

4. Wear in moving parts

Hinges dry out and squeak, lock cylinders gum up, closers lose oil, sliding rollers flatten. Lubrication and small part swaps handle most of this.

5. Damage and decay

Impact cracks, water rot, borer, and lifting veneer are material failures. Small ones patch; severe rot or a warped solid leaf often means replacement — don’t throw good money at a dead door.

A 5-minute diagnosis: numbered steps

Work through these before you reach for a tool. Most jobs here are easy and take 5–15 minutes.

1. Watch the swing. Open and close slowly. Note exactly where the leaf touches — top corner, latch edge, floor, or all over.

2. Read the gaps. A tapered reveal (wider at top, tight at bottom on the latch side) means a sagging top hinge.

3. Wiggle the leaf. Lift the handle edge; if it moves and the top hinge clunks, screws are loose — tighten them first.

4. Check the latch line. Mark the latch tongue with a pencil, close the door, open it: where the mark lands shows if the strike is too high, low, or shallow.

5. Test damp spots. If it only jams in monsoon, it’s swelling, not structure — don’t plane yet.

6. Listen. Squeaks mean dry hinges; grinding on a slider means a dirty track.

7. Decide. Match your findings to the master table and open the matching spoke.

When to stop and call a professional

DIY is great until safety or value is on the line. Stop and call a carpenter or specialist if:

The door is structurally sagging because the frame has dropped or rotted — forcing it makes it worse.
The leaf is warped or rotted through; a twisted solid door rarely comes back. Price a door replacement instead.
It’s a glass door with a cracked panel or toughened-glass fault — glass under tension is dangerous; a pro must handle it.
It’s an automatic, sensor, or auto-operator door — isolate power first, then call service. India’s voltage fluctuation also stresses these operators.
There’s active termite or borer in the frame and surrounding joinery, not just the leaf.

For routine upkeep that prevents most of these faults, follow the door maintenance guide and set reminders with the home door maintenance planner. For the bigger picture across types and fittings, the complete door guide is your home base, and the deeper door repair guide covers method in detail.

Frequently asked questions

Why does my door only stick during the monsoon?

The timber or flush leaf is absorbing humidity and swelling along its edges, then shrinking back in drier months. Don’t plane it on the first damp day or it will rattle later — instead seal all six edges with polish or paint and only ease a spot that binds year-round. See swollen door monsoon fix.

My door won’t latch even though it closes — what’s wrong?

Nine times out of ten the latch tongue no longer lines up with the strike plate hole, usually because a hinge has loosened and the door has dropped. Tighten the top hinge first, then re-align or file the strike. Full method in door not latching.

Can I fix a stripped hinge screw myself?

Yes, this is an easy 15-minute job. Pack the hole with wooden matchsticks or toothpicks and glue, let it set, then re-drive the screw — or use a longer screw into the wall stud. Steps in stripped hinge screw fix.

How do I know whether to repair or replace a door?

If the structure (the leaf core and frame) is sound, almost any surface or hardware fault is worth repairing. Replace when the leaf is warped, the core is rotted, or repair costs approach a new leaf at ₹3,000–6,000. The repair vs replace door calculator gives a clear answer.

Is it safe to work on an automatic door myself?

No — isolate the power and call a service technician. Auto and sensor doors involve operators, springs, and electronics that are unsafe and easy to damage, and India’s voltage swings already stress them. See automatic door troubleshooting.

What’s the single most common door problem?

Loose hinge screws. They cause sagging, rubbing, uneven gaps, and latch failures all at once, yet the fix is often just tightening or re-anchoring the screws. Start there before assuming anything worse — see fix loose door hinges.
