If you’ve scrubbed black mould off your walls or ceilings, only to see it return weeks later, you’re not alone. Across Warrington, many homeowners face the same frustrating cycle — clean, repaint, and then repeat.
The reason? Mould isn’t just a surface problem. It’s a symptom of trapped moisture and poor air circulation.
At Weather Wise Solutions, we specialise in identifying why mould keeps returning and how to stop it permanently through proper ventilation and moisture control.
💧 Why Cleaning Alone Doesn’t Work
Household cleaners or mould sprays only kill surface spores.
They don’t address the root cause — excess humidity, poor airflow, or cold surfaces that encourage condensation.
If condensation levels remain high, mould will regrow as soon as humidity reaches around 70% relative humidity or higher.
Typical causes include:
-
No trickle vents or blocked air pathways
-
Drying clothes indoors
-
Inconsistent heating or cold bridging
-
Lack of continuous extraction in kitchens and bathrooms
Without tackling these conditions, cleaning simply provides short-term relief.
🌬️ How to Stop Mould Coming Back
The long-term fix is continuous moisture control.
At Weather Wise Solutions Limited, we use a proven three-step approach:
✅ Improve ventilation – install Decentralised Mechanical Extract Ventilation (DMEV) units or Positive Input Ventilation (PIV) systems to maintain healthy airflow.
✅ Reduce humidity – encourage trickle vent use and maintain low-level background heating.
✅ Apply breathable finishes – vapour-open paints and plasters allow trapped moisture to escape safely.
This combination keeps indoor humidity below the dew point, preventing condensation and mould regrowth.
