When you see a water stain on the ceiling, check whether it is active (damp to touch, growing, dripping), make nearby electrics safe, and note when it appears: after the flat above showers, when the AC runs, or after rain. Then have the source traced. Painting over a stain without fixing the source only hides the problem.
Is it active or old?
Mark the edge of the stain with a pencil and check again in 24 to 48 hours. Press gently: soft or damp gypsum means active water. Look for drips from light fittings and AC diffusers.
Match the timing to the cause
- After the upstairs bathroom is used: shower waterproofing, floor trap or WC connection above.
- When the AC runs: blocked or disconnected condensate drain. See ceiling leaking when the AC runs.
- All the time: a pressurised supply pipe in the ceiling void.
- After rain: roof, terrace or balcony above.
What to do now
Switch off circuits near the stain if it is wet, put a bucket under drips, photograph it, and inform building management if you are in an apartment. If the ceiling bulges, it is holding water: a small hole at the lowest point lets it drain safely.
Get the source traced
Book ceiling leak detection, or for active dripping call our ceiling leak emergency line. Repairs to the ceiling should wait until the source is fixed and the area has dried.
Dubai homeowner checklist
- Mark the stain edge with pencil and check after 24 hours.
- Switch off lights and circuits near any active drip.
- Note when the drip happens: after showers upstairs, with the AC, or after rain.
- Inform building management in towers so the unit above can be checked.
