Condensation is one of the most common causes of damp in North Wales homes—especially in older properties and those that have been sealed up for energy efficiency. Unlike rising or penetrating damp, condensation occurs when warm, moisture-laden air hits a cold surface like a windowpane, uninsulated wall, or ceiling. If left unresolved, it can lead to black mould, damaged décor, and even health issues.
At Weather Wise Solutions Limited, we regularly help homeowners across North Wales tackle condensation through practical ventilation solutions such as trickle vents, extractor fans, and Positive Input Ventilation (PIV) systems, sourced from trusted suppliers like PAM Ties.
🔍 Common Signs of Condensation in Your Home
If you're unsure whether you're dealing with condensation, here are some of the key tell-tale signs:
-
Streaming windows, especially in the morning
-
Black mould forming around window reveals, ceiling corners, or behind furniture
-
Peeling paint or blistered wallpaper
-
Musty smells in bedrooms or bathrooms
-
Clothes taking longer to dry indoors
-
Water pooling on windowsills or bathroom tiles
Condensation is often misdiagnosed as rising damp, but the location and symptoms are usually different. Condensation tends to appear higher up on internal walls and near areas with poor ventilation.
💨 How to Fix It: Effective Condensation Control
Modern building regulations, including Part F, require adequate ventilation to control indoor air quality and moisture levels. Homes with sealed windows, inadequate extraction, or blocked vents will struggle to meet these standards.
To address condensation in North Wales homes, we typically recommend:
-
Trickle Vents – discreet vents added to windows to provide a constant flow of fresh air
-
Extractor Fans – especially in bathrooms and kitchens
-
Positive Input Ventilation (PIV) – loft-mounted systems that gently push out stale, humid air and replace it with drier air from outside
-
Moisture Mapping – to ensure there are no hidden leaks or other contributing factors
These systems are reliable, energy-efficient, and help ensure compliance with ventilation guidance from local councils.
