Condensation is the most common causes of dampness in
homes and cause the majority of reported damp
problems.
It forms when warm moist air comes into contact with and
condenses on a cold surface.
Every home suffers from condensation as it is created
during and after cooking, washing clothes and bathing which
all produce warm moist air.
It is also quite normal to find your windows misted up after a
cold night and there is nothing much you can do to stop this.
However, condensation can be a more serious problem and is
directly associated with the growth
of
damp and mould.
Condensation usually affects properties between October
and April when home ventilation is at its lowest.
During these months people close windows and doors
causing water vapour to build up creating condensation.
It appears on cold surfaces and in places where there is little
movement of air next to outside walls, glass, furniture
and clothing often affected.
You should look out for it in corners, on or near windows,
behind wardrobes and cupboards and on north-facing walls.
Condensation does not leave a tidemark but
the following symptoms can point towards a condensation
problem:
- Development of mould, usually black, on walls,
ceilings and other surfaces
- Slightly damp wallpaper
- Water droplets forming on cold and solid surfaces such as
glass and paint
