Why Are My Walls So Cold?
Most older homes in Bristol were built with solid brick or block walls and have little to no insulation. This means heat escapes quickly through the external walls, leaving the inside surface cold.
When warm, moist air from cooking, showering, drying clothes and even breathing touches a cold surface, the moisture turns into water droplets. Over time, this leads to:
Cold internal wall surfaces
Damp patches
Mould growth
Peeling paint or bubbling plaster
Rooms that feel colder than the rest of the home
New windows and doors can also trap moisture inside, making condensation worse.
What’s Actually Happening
Cold walls are the result of heat loss + moisture in the air.
Warm air always moves toward colder surfaces
As the warm air cools, it reaches dew point
Moisture drops out of the air and settles on the cold wall
This repeated cycle causes damp, staining and mould
In short, your walls are cold because they’re uninsulated, and condensation forms because the air inside your home holds more moisture than the walls can handle.
The good news: this is fully fixable, and once the wall surfaces stay warm, condensation and mould disappear.
