Bengaluru: what to know
Bengaluru's rainy spells raise humidity in closed rooms, and damp outer walls can seep onto mattresses and wardrobes placed against them. Mould spots appear behind furniture first, where air does not move, and a faint smell on bedding is often the early warning.
What to do next
Leave a hand-width gap between the bed and the wall, ventilate between showers, fix leaks early and check behind wardrobes at the start of each monsoon.
Rainy-season checks
- Look for damp patches and peeling paint.
- Move beds a hand-width from outer walls.
- Check behind wardrobes monthly.
- Fix leaks and seal windows.
- Air bedding between showers.
When to call a professional
Persistent damp, spreading mould or leaks need a building repair, not just cleaning.
Detailed guidance
Bengaluru's rainy spells raise humidity, and damp outer walls can transfer moisture to mattresses and wardrobes placed against them. Mould often shows first behind furniture where air does not move. Leave a hand-width gap between the bed and the wall, ventilate between showers and keep windows closed in heavy rain only.
Check walls for damp patches and peeling paint, and look behind wardrobes monthly during the rains. Fix leaks early, seal windows and repair external cracks. Use silica bags and a dehumidifier in closed rooms if needed. Air bedding in dry hours and wash protectors more often. Persistent damp or spreading mould needs a building repair, not just cleaning, so ask a professional to check the cause.
Common mistakes to avoid
People often assume a damp patch will dry by itself. If the cause is seepage, it will return each rainy season. Look for the source, such as a leaking pipe, a cracked wall or a blocked drain, and have it repaired before you treat the surface.
Another error is pushing the bed against a damp wall. Move it a little away, and lift any items stored under it. Check the back of the headboard and the underside of the mattress.
Finally, painting over damp rarely lasts. Paint on a wet wall blisters and traps moisture, and fresh paint can hide a growing problem. Ask a professional to assess the cause, ventilate the room, use a moisture meter if you can and replace bedding that has absorbed damp and stays musty.
Quick checklist
- Find and repair the source of seepage first.
- Keep the bed away from damp walls.
- Check the back of furniture and the underside of the mattress.
- Ventilate the room on dry days.
- Avoid painting over a wet wall.
- Call a professional if damp keeps returning.
