When cold weather sets in across Tamworth, many homeowners notice condensation forming on windows and walls — often leading to black mould, damp smells, and peeling paint.
But why does it always seem worse in winter?
At Weather Wise Solutions, we help homeowners understand the science behind condensation — and more importantly, how to stop it.
💧 The Science Behind Winter Condensation
Condensation forms when warm, humid air meets a cold surface, such as an external wall, window, or ceiling.
In winter, two main factors make this worse:
1️⃣ Temperature Difference
Cold outdoor air cools the internal walls, reducing their surface temperature.
When indoor humidity hits that cold surface, moisture condenses instantly — especially around corners, windows, and cold bridges.
2️⃣ Reduced Ventilation
During winter, windows stay shut and trickle vents are often closed to keep heat in.
This traps moisture from everyday activities — cooking, showering, and even breathing — allowing humidity levels to build up indoors.
🧊 Common Signs of Winter Condensation
If you notice any of the following during colder months, you may have a ventilation imbalance:
-
Water droplets forming on windows or sills
-
Mould appearing in corners or around window reveals
-
Musty smells in bedrooms or bathrooms
-
Damp patches that fade during warmer weather
These are all signs that your home is retaining moisture faster than it can escape.
🧰 How to Prevent Condensation During Winter
At Weather Wise Solutions Limited, we combine ventilation upgrades with thermal improvements to tackle the root cause — not just the symptoms.
✅ Install a PIV System – Introduces a steady supply of filtered, drier air from the loft into your living spaces, helping push out moisture-laden air.
✅ Fit DMEV Fans – Ideal for bathrooms and kitchens, these humidity-sensing fans extract air automatically before condensation can form.
✅ Reduce Cold Bridging – We inspect insulation and wall linings to ensure surfaces stay warm enough to prevent dew-point formation.
✅ Maintain Consistent Low-Level Heating – Prevents large temperature swings that lead to condensation on cold surfaces.
All our ventilation systems are supplied from trusted UK manufacturers, including PAM Ties and Wycamol
🌡️ Why Condensation Control Matters
Ignoring condensation can lead to:

Black mould growth on walls and ceilings
-
Peeling paint and wallpaper
-
Damage to plaster and window frames
-
Poor indoor air quality and health issues
Controlling humidity and ventilation ensures your home stays warm, comfortable, and mould-free — even through the coldest months.
