Damp Walls & Health

We’ll show you how to stop wall mould from hurting your family, and the one trick you must avoid.

Never mix cleaners

Mixing bleach with acid or ammonia creates toxic gases that burn eyes, throat and lungs, especially in a closed bathroom. If anyone coughs hard or feels tight-chested, get fresh air immediately and seek urgent care.

What mould can do

Damp itself isn’t the problem; it’s the mould and dust mites that grow on wet walls. Their spores can trigger wheezing, blocked noses and itchy eyes, especially for babies, the elderly and anyone with asthma.

Cough lasting

If a cough lingers over three weeks, see a doctor.

Control indoor moisture

Condensation from cooking, hot baths and indoor drying adds water to the air, which settles on cold walls. Simple swaps, like using lids, opening windows and drying laundry outside, cut down that moisture dramatically.

Clean small patches safely

For a small mould spot, clear the room of babies and asthma sufferers, put on gloves, goggles and an N95 mask, lightly mist the area with water, then wipe with a detergent solution. No dry brushing.

The one mistake to avoid

Don’t just paint over damp spots; you must fix the water source first, or the mould will return after a season. Repair leaks, improve ventilation, and only then consider repainting.
