There are various solutions for reducing draughts in the home, but you need to know how to identify their sources and make them disappear. In general, doors are the most common culprit for draughts, but there are also DIY solutions you can try. Listed below are a few simple ways to stop draughts in your home.
You can also seal gaps in doorways. One common place to find gaps is at the bottom of the door, where the carpet or other hallway flooring has a gap between the bottom of the door frame. To seal these gaps, you can buy draught excluders or find replacement doors which are a better fit. However, you should take care to seal the edges and top of the door, as these areas can be prone to draughts. They can be made of foam or rubber, and can be attached to the frame using screws or adhesive.
For those with downlights, prevent draughts by installing Downlight Covers, available from a site like https://www.thermahooddirect.com/
Another cheap way to reduce draughts is by using weather stripping around the window frames. If you have timber doors, you can fill the gaps with suitable wood filler or paint over them. You can also try making a draught excluder yourself. If you have a persistent draught through the letterbox, it might be time to consider a new one or even an external wall-mounted letterbox so you can fill in the gap in the front door completely.
