Damp is something than can affect homes with no ventilation. It causes mould on walls, furniture and can make window frames and other wooded areas rot. Dampness also has its health risks too – a cold damp house encourages the growth of mould and mites and as mites feed on mould it can increase the risk of respiratory illnesses such as asthma in some people.
How do you know if you home has damp?
• Condensation on hard surfaces
• Water stains
• Swelling and rotting wood or wood-based materials
• Rotting carpet
• Bubbling wall linings and vinyl floor coverings
• Musty smells
Rising damp, penetrating damp and condensation are the three most common types of damp and there are three ways to combat persistent damp: insulate, ventilate and heat.
Condensation occurs when moist air hits a cold surface. This moist air condenses on cool surfaces such as walls, mirrors, tiles and windows. Look for it in corners, near windows, behind wardrobes, inside cupboards, on the ceiling or places where there is little movement of air.
It’s mainly a winter problem as this time of year walls are much colder than the air inside. Condensation can be brought on by poor ventilation and heating that comes on and off, as this allows warm, damp air to condense.
Symptoms of condensation:
• Water droplets on windows or walls
If left untreated, condensation can damage paint and plaster and cause window frames to decay.
Let moist air out and dry air in by:
• Opening your windows – especially in wet areas such as bathrooms and kitchens
• Closing doors to contain steam/condensation in wet areas
• Using extractor fans in bathrooms
• Venting clothes dryers to the outside. A typical load contains 5 litres of water. This is released as water vapour, which can create thousands of litres of damp air
• Use a dehumidifier or forced ventilation system
Insulation in the ceiling or wall insulation will help keep your home warm not to mention keep your energy bills down. When the whole home is warmer, condensation is less likely. Please see my blog for Insulation and home building for more information.
Heat your home to a healthy temperature
Keeping your home warm is important for your health and comfort, and a good heating system coupled with proper insulation, ventilation and moisture control will prevent damp.
