Doors and Windows That Won't Close Properly: What's Actually Wrong and How It's Fixed
A door that swings open on its own is a plumb problem, not a hinge problem. How to read what a sticking door or leaking window is actually telling you, IS 4021 gap tolerances, and repair costs.

The short answer
- A door that swings open by itself is out of plumb at the frame — no amount of hinge adjustment fixes that permanently; the frame itself has to be corrected.
- IS 4021 sets the tolerance: a door's perimeter gap should be 1–3 mm and the sill gap 6–10 mm; wider gaps whistle, let dust in, and are a workmanship defect rather than a design quirk.
- A sliding window that lets rain in even when fully closed is almost always blocked or missing weep holes in the bottom track, not a sealing problem — pour water into the track to check.
- A window that rattles or whistles at the glass edge usually has a shrunk-back or missing rubber gasket, not a frame problem.
- Fix the frame or track issue before replacing hardware — new locks and handles on a frame that's out of plumb, or a track with no drainage, will fail the same way again.
Reading what's actually wrong
- A door that swings open by itself: the frame is out of plumb, not a hardware fault.
- Whistling or a draught at a closed door or window: the gap is wider than specification, or the brush pile/seal is missing.
- Stiff sliding action: grout or debris in the track, or worn rollers — rarely the lock or handle.
- Water pooling in the sill after rain even with the window fully closed: blocked or missing weep holes in the bottom track.
- A rattling pane of glass: a shrunk-back or missing rubber gasket at the glazing edge.
Doors: frame, gap and hardware
- Frame jamb plumb should be within ±2 mm over its full height, per IS 4021 — check this before blaming the hinges for a door that won't stay shut.
- Perimeter gap should sit between 1–3 mm and the sill gap between 6–10 mm. Wider gaps are a workmanship defect, not a design feature, and they let both dust and draughts through.
- Every hinge should have all its screws present and driven fully home — a hinge running on two screws out of three will drop the door within a year, and that's a hinge-level fix rather than a frame problem.
- The strike plate should be fitted flush and the latch should engage fully without lifting or forcing the shutter — a common sign the frame or the plate itself is slightly out of alignment.
Sliding windows: track, brush pile and weep holes
- Brush pile (the sealing felt) should run continuously along the interlock and frame — missing or shrunk-back pile is why a fully closed window still lets in dust, noise and driving rain.
- Weep holes in the bottom track need to be present, open and draining outward. Pour water directly into the track and watch where it goes — blocked or missing weep holes hold rainwater in the track until it eventually overflows into the room.
- A stopper and hook lock should engage on every shutter, including the second and third panels that are easy to forget to test on a multi-panel slider.
- The handle should be screwed tight with no play, and the lock should engage smoothly with the shutter fully closed on its own — not only when it's pulled in by hand first.
The rain test
Hose the external face of a closed window for a few minutes and watch the inside reveal for any sign of water. It's the same check used at a proper handover inspection, and it's worth repeating after any repair — a sealed-looking window that hasn't actually been tested under water tells you nothing.
Fix versus frame or track replacement
| Symptom | Usual fix | When a full replacement is needed |
|---|---|---|
| Self-swinging door | Re-set or pack the frame to plumb | If the frame itself is warped or undersized, not just misaligned |
| Wide perimeter gap | Reset the shutter and hinges within tolerance | If the frame opening is oversized for the shutter fitted into it |
| Water pooling in the window track | Clear or re-cut weep holes, refit the brush pile | If the track itself was made with no drainage provision at all |
| Rattling glass | Refit or replace the glazing gasket | Rarely — this is almost always a gasket-level fix |
What this costs
| Repair | Cost |
|---|---|
| Door alignment / hinge repair (per door) | ₹500–₹2,000 |
| Door frame replacement (per door) | ₹4,000–₹15,000 |
| Window frame / glass replacement (per window) | ₹3,000–₹20,000 |
| Lock / hardware replacement (per unit) | ₹400–₹2,000 |
Get it fixed while the builder is still liable
Door and window workmanship defects are covered the same way as any other under RERA Section 14(3) — reported within five years of possession, rectified at no cost. Get each one onto a dated, written snag list before you sign the possession letter, and re-test after the repair rather than accepting a verbal confirmation that it's done.
Frequently asked questions
My bedroom door keeps swinging open on its own. What's wrong with it?
This is almost always the door frame being out of plumb rather than a hinge fault. Hinges can be adjusted, but a frame installed off-plumb will keep producing the same symptom until the frame itself is corrected.
Why does my sliding window let water in even when it's fully closed?
The most common cause is blocked or missing weep holes in the bottom track, which trap rainwater instead of draining it outward until it overflows into the room. Pour water into the track to check before assuming it's a sealing problem.
Is a gap around my door frame normal, or is it a defect?
IS 4021 allows a perimeter gap of only 1–3 mm and a sill gap of 6–10 mm. Anything noticeably wider than that is a workmanship defect worth flagging, not a normal tolerance.
Can I just replace the lock if my door doesn't latch properly?
Only if the strike plate and latch alignment are the actual cause. If the underlying issue is a frame out of plumb or a warped shutter, a new lock will show the same symptom again shortly after fitting.
Is the builder responsible for door and window defects found after possession?
Yes, within the five-year RERA Section 14(3) window, since these are workmanship defects. Documenting each one with photographs and a written complaint at the time it's found makes the claim easier to enforce later.
