Why stop draughts?

A draught is air moving around your home, usually caused by gaps around the outside of the building that are allowing warm air out and cold air in. You need ventilation in your house, to stop it getting damp, but you need to be able to control it.

Windows, doors, floors, letterboxes, keyholes and loft hatches can all let warm air escape from your house and let cold air in. The sensation of air moving around your house also makes you feel colder.

If you’ve got draughts, you’re losing heat you’ve paid for and you have to run your heating more to keep up the temperature in your home. It costs you more and increases your carbon footprint.

Sealing up these draughts can often be very straightforward and most people with basic DIY skills can tackle them.
