💧 What Causes Condensation on Internal Walls?
Condensation forms when warm, moist air comes into contact with cooler surfaces—like internal walls and corners of rooms. It’s especially common in homes with limited airflow, where moisture from daily activities like cooking, bathing, and drying clothes builds up without escaping.
Left untreated, this condensation leads to:
✅ Mould growth in corners and behind furniture
✅ Peeling paint and wallpaper
✅ Musty odours
✅ Unhealthy indoor air quality
🔍 How to Spot Internal Wall Condensation
Look out for these signs in your home:
-
Cold walls with beading or wet patches, especially in winter
-
Black mould forming in corners or behind large furniture
-
Peeling paint or wallpaper that won’t stay stuck
-
Condensation on windows, especially first thing in the morning
These issues often worsen in bedrooms, living rooms, and behind wardrobes, where airflow is limited.
🌬️ Effective Ways to Treat Internal Wall Condensation
At Weather Wise Solutions, we tackle condensation at the source with:
✔️ Positive Input Ventilation (PIV) systems from PAM Ties – continuously introduces fresh, filtered air and pushes out moisture-laden air
✔️ Home ventilation assessments to find blocked or ineffective vents
✔️ Advice on reducing indoor moisture—like using lids while cooking or drying clothes outdoors
✔️ Optional installation of additional air bricks or trickle vents where needed
We also follow GOV.UK housing damp guidance to ensure your home stays safe, dry, and compliant.
🛠️ Why a PIV System Works So Well
Unlike extractor fans, a PIV system runs quietly and continuously, distributing filtered air from your loft space into your home. This reduces the concentration of moisture in the air, helping to prevent mould and protect internal walls year-round.
