Warm air holds moisture. When that warm, moist air hits a cold surface (like a chilly outside wall or a bedroom window), it dumps that moisture as water droplets. This is why you see:
Water on windows in the morning
Damp patches in cold corners
Mould behind furniture
Peeling paint and wallpaper
That familiar “wet dog” smell
Daily life creates far more moisture than most people realise cooking, showers, drying clothes indoors, even just breathing.
Modern homes don’t help: Double glazing, insulation and sealed-up chimneys all trap that moisture inside
APPROACH
How Fix Condensation Properly
01
A proper survey
We measure humidity, check airflow, look for cold spots, and assess the property’s ventilation above and below the floor.
02
Positive Input Ventilation (PIV)
A long-term, low-energy solution that introduces fresh, filtered air into the home and pushes out the moisture-laden air.
03
Upgraded extractor fans
Most homes have fans that are too weak, broken, or don’t run long enough.
04
Subfloor ventilation checks
Poor airflow under wooden floors often leads to cold floors and high humidity in the rooms above.
05
Practical, simple advice
Things you can do day-to-day that make a real difference.
Why Condensation is a Problem
Left alone, it leads to:
Black mould
Damage to plaster and paint
Damp, cold rooms
Dust mites
Health risks
Poor indoor air quality
It’s not just uncomfortable — it’s unhealthy. The good news? It’s usually one of the easiest problems to fix — once you understand why it’s happening
DIY FIXES
Why DIY Fixes Usually Don’t Work
If the moisture isn’t being removed from the home, the problem will always return
Opening windows wastes heat.
Dehumidifiers only help one room.
Paint doesn’t fix damp.
Bleach only hides mould.
With the right ventilation strategy, condensation can’t survive.
Our goal is simple: A warm, dry, healthy home with fresh air — every day of the year
