If you live in Chorley and have one internal wall that always feels cold, damp, or slightly clammy, even when the heating is on, the cause is usually thermal bridging.
This often happens in older Lancashire homes where certain walls lose heat faster than the rest of the room — making them prime targets for condensation and mould.
At Weather Wise Solutions, we help homeowners identify these cold spots and fix the underlying issues, not just the symptoms.
🧊 What Makes an Internal Wall Cold?
A cold internal wall isn’t just a comfort issue — it’s usually a sign that the wall is losing heat to the outside or to an uninsulated area of the property.
The most common causes include:
1️⃣ Thermal Bridging
A “thermal bridge” is a pathway where heat escapes more easily.
Typical examples in Chorley homes include:
-
Single-skin brick walls
-
Concrete lintels
-
Uninsulated gable ends
-
Solid walls without cavity insulation
-
Cold chimney breasts
-
Timber joists within cold voids
When warm indoor air hits these cold surfaces, condensation forms instantly, feeding mould and damp smells.
2️⃣ No or Poor Insulation
If the wall separates the room from a garage, hall, unheated extension, or stairwell, it will naturally be much colder.
3️⃣ Furniture Blocking Airflow
Wardrobes, beds or drawers placed against an outside wall trap cold air — creating a microclimate where mould thrives.
4️⃣ High Indoor Humidity
Cooking, showering, and even breathing add moisture into the air.
Without good ventilation, that moisture settles on the coldest wall in the room.
💧 Why Cold Walls Become Damp
Cold walls attract condensation like a magnet.
When moisture repeatedly settles and evaporates, it can lead to:
-
Black mould in corners
-
Damp patches that “come and go”
-
Peeling paint or bubbling plaster
-
Musty odours around furniture
-
Increased humidity levels
This is not rising damp — it’s temperature-driven surface moisture.
