Advice for keeping your home damp-free
Condensation occurs when warm air comes into contact with a cooler surface. It can appear as droplets on walls, ceilings, furniture and windows.
It tends to be worse in winter and this extra moisture known as damp, often turns into black mould. You may have damp in your home due to:
- leaking supply and waste pipes
- slipped roof tiles or worn flat roofs
- blocked guttering
- gaps around window frames
- cracked rendering and brickwork.
Prevent condensation in your home
The only lasting way to reduce condensation is to improve ventilation. You can do this by following these steps:
Control moisture levels
- Dry clothes outside when possible, or on a clothes dryer in a sunny, well ventilated area. Don't dry laundry on radiators.
- When bathing or showering use the extractor fan and keep windows open.
- When cooking cover pans and use the extractor fan. Keep internal doors closed and ensure kitchen windows are open.
- If you see any moisture on mirrors, windows and tiles around the home, wipe these down using a dry towel.
Control heat and ventilation
- Keep a small window or a trickle ventilator open in occupied rooms. Don’t block air vents.
- Aim to keep temperatures between 18˚C and 21˚C in main living areas. In cold weather, keep low heating on, even when no one is home. This is better than shorter bursts of high heat.
- It is important that your heating system is serviced regularly.
- Consider insulating your home and laying thick carpet with thermal underlay.
