How to spot signs of mould

Mould can grow on hidden surfaces, walls, windows, doors or even on clothes and wardrobes. Spotting the signs of mould and damp is the first step to clearing it away from your property.

Look out for damp

  • Keep an eye out for damp patches on walls or ceilings, look for a tea stain appearance and if you find one, check outside for leaking pipes, gutters etc
  • Check around pipework of toilets and sinks for leaks
  • Follow your nose – pay attention to unmistakeable damp smells
  • Look out for peeling wallpaper, or walls that feel damp to touch
  • Check that seals around baths, sinks and showers are watertight

Outside issues to look out for

  • Missing or loose roof tiles, blocked or leaking gutters, damaged or loose lead flashings
  • Leaking or broken external pipes such as waste pipes
  • Missing vents or covers such as extractor fan covers
  • Cracks or gaps around doors and window frames, inside and out
  • Open jointed brickwork, damp/wet brickwork especially at low level below dampproof course (DPC)
  • Broken or cloudy double glazing
  • Blocked or overflowing gullies and inspection chambers

Safety in the home

  • Fire safety – Check and test your smoke detector every month

  • Windows and doors – Check for draughts, and make sure all locks operate securely


  • Monitor your water pressure and notice if it runs too hot or too cold
  • Look out for corrosion to copper pipework or leaking joints to plastic waste pipes
  • If your radiators aren’t coming on, take a look at the pressure gauge on your boiler


  • Check for leaks or blockages in drains and pipes
  • Don’t use more than the recommended washing powder dose in a laundry load – too much can cause blocked drains
  • Only flush toilet paper and bin everything else to avoid blockages
