How to remove bathroom mould in Birmingham homes (and stop it coming back)

10 October 2026 · 4 min read

Birmingham's older housing stock and seasonal damp mean mould is one of the most common cleaning problems we see. Here is how to remove it properly and, more importantly, how to stop it returning.

Safety first

  • Open windows and run the extractor fan
  • Wear gloves and a mask for large patches
  • Never mix bleach with other cleaners

For light mould on tiles and grout

  • Spray a diluted bleach solution or dedicated mould remover
  • Leave for 10 to 15 minutes
  • Scrub grout with an old toothbrush
  • Rinse thoroughly and dry

For painted walls and ceilings

  • Do not scrub hard or you will damage the paint
  • Use a mould remover suitable for painted surfaces
  • Repaint with mould-resistant paint once fully dry

Why it keeps coming back

  • Ventilation is more important than the product
  • Dry the shower and tiles after use
  • Keep the window open or the fan running for 20 minutes after bathing
  • Fix any leaks behind sealant or under the bath

When to call a professional cleaner

  • If mould covers more than a square metre
  • If it keeps returning after treatment
  • If you need it documented for a landlord or deposit
  • Preshine deep cleans include bathroom mould treatment
