What's usually going on
- Poor or broken extraction / ventilation
- Failed silicone and grout letting damp in
- A concealed leak feeding constant moisture
- Cold surfaces where condensation forms
Cleaning mould off treats the symptom; it comes back because the moisture behind it is still there. We work out whether it's ventilation, failed sealing or an actual leak, treat the mould properly, and fix the underlying cause — a new extractor fan, fresh seals, or a leak repair.
That's the difference between wiping it away for a fortnight and actually getting rid of it.
