Mould

What Causes It and How to Stop It for Good

Mould isn’t just unpleasant — it means moisture in your home is too high. Black, green, or white mould on walls, windows, ceilings, or furniture is usually a sign of poor ventilation or cold surfaces, not a one-off issue.

Why Mould Appears

Mould needs three things to grow: 1. Moisture 2. Food – Organic Material and Heat Once those conditions exist, mould spreads quickly — sometimes in as little as 24–48 hours. The most common causes are:
  • High internal humidity
  • Condensation on cold walls and windows
  • Poor or inadequate ventilation
  • Subfloor moisture affecting the rooms
  • Blocked, broken, or weak extractor fans
  • Drying clothes indoors

Fixing mould means fixing the moisture source — not just cleaning the spots.

Is Mould Dangerous?

According to the NHS, mould can trigger or worsen:

  • Asthma
  • Breathing problems
  • Respiratory infections
  • Allergies and skin irritation
  • Headaches and fatigue

Young children, elderly people, and anyone with respiratory conditions are particularly vulnerable.
The tragic case of Awaab Ishak showed the very real dangers of living with untreated mould. It’s not something to ignore.

What You Can Expect

The goal isn’t just to remove the mould — it’s to stop it for good. Once the moisture source is dealt with:
  • Mould stops returning
  • Rooms smell fresher
  • Air feels lighter and cleaner
  • Windows dry out
  • Walls stay warm and dry
  • Respiratory irritation reduces
Cleaning it off is only ever a temporary fix. If the conditions stay the same, the mould will come straight back.
