To many, the phrase ‘rising damp’ means nothing more than a vague reference to a 70s TV show about a diverse set of characters living in a small flat, but damp can be a very real and consistent problem for householders.
It’s a visible and unsightly issue that can lead to further problems within a structure. Damp and mould are caused by the presence of unwanted moisture within a building, either by entering from outside or by condensation within. It is possible to prevent it happening and, if it has already started, to take steps to get rid of it.
Here are 4 ways to help you deal with damp:
1. Reduce condensation
Prevent the build-up of condensation by wiping down susceptible windows and surfaces regularly. Try to avoid drying clothes on radiators as the damp air will transfer onto walls. Condensation strips can be bought at DIY shops which will help prevent window frames from rotting and damp collecting on sills.
2. Take steps against mould
To kill and remove mould, carefully wipe down walls and surfaces affected using an approved fungicidal wash. Also dry-clean mildewed clothes and shampoo carpets. Avoid brushing or vacuuming mould as disturbing it in this way can lead to respiratory problems. Once it has been removed, redecorate if needed with special fungicidal paints and wallpaper pastes. Remember that painting over fungicidal paint with ordinary paint will stop it working.
3. Check for other causes
Condensation within a property is not the only cause of damp. Check for leaking pipes, wastes or overflows. Another major cause of damp can be broken tiles or blocked gutters. Has the house ever had a damp proof course? It’s worth checking the property records as older houses may not have been treated. And if they have, ensure it has not become defective.
4. Let your house breathe
Modern houses come with excellent insulation, designed to keep heat in. However they should also have facilities to allow air to circulate. If possible, keep a small window or a trickle ventilator open at all times.
The real hot spots for damp due to poor ventilation are the kitchen and the bathroom. When these rooms are in use, keep the doors closed and turn on extractor fans. Draught-proofing these doors will also help to stop condensation spreading to other rooms, especially bedrooms that are often cooler allowing condensation to build up more rapidly.
