It is important to bring condensation in a property
under control as it can lead to lead to major
problems.
If left unattended it can lead
to
damp and mould problems which can cause serious damage to a
home.
Condensation forms when warm moist air comes into contact with
and condenses on cold surfaces.
Every home suffers from some condensation but much can be
done to prevent it from building up and becoming a bigger
problem.
If you have a condensation problem it can be controlled using
the following methods:
- Avoid using paraffin and portable flueless bottled gas heaters
as they produce moisture
- Close kitchen and bathroom doors when in use even if
they have extractor fans
- Cover cooking pans and do not leave kettles boiling - Prevents
them producing warm moist air
- Dry washing outdoors or in a closed bathroom
with a window open or fan on
- Externally vent tumble dryers or make
them self-condensing using the available DIY kits
- Improved heating - Set heating sources to give a low-level
background heat ensuring there are no rapid temperature changes
which cause condensation especially in extremely cold weather
- Improved ventilation - Open windows to help take damp air out
of a property or ensure new frames have trickle ventilators
- Install a dehumidifier or humidistat-controlled electric
fan - Both take moisture out of the air
- Install cavity wall insulation. Information about grants
are available from Warm
Front and Warm
Streets
- Install loft insulation - Remember to draught-proof the
loft hatch but do not block openings under the eaves.
- Install secondary or double glazed windows - Reduces heat
loss and draughts but ensure there is some ventilation
- Ventilate cupboards and wardrobes - Avoid putting too many
things in them as this stops the air circulating,
cut ventilation slots or breather holes in backs and
doors, leave spaces between them and the wall or
position them against internal walls
- Ventilate kitchens and bathrooms, when in use by opening the
windows wider
The following should be considered when taking steps to prevent
condensation:
- Do not block permanent ventilators
- Do not completely block chimneys - Leave a hole about two
bricks in size and fit a louvered grille over it
- Do not draught-proof rooms where there is condensation or
mould
- Do not draught-proof a room where there is a cooker or a fuel
burning heater such as a gas fire
- Do not draught-proof windows in bathrooms and
kitchens
