How to draught-proof a door
You will need:
- Craft knife
- Electric drill
- Panel pins
- Foam strip
- Nylon brush draught excluder
Draughts account for as much as 25% of the heat loss in a home, so adding draughtproofing can make your home much more comfortable and cheaper to run. Draughtproofing a door is a simple DIY job that can make a big difference in cold weather.
Time to complete job: Under 20 minutes.
Approximate budget: Less than £25 for the average sized home.
TOP TIP: Before you start fitting any draughtproofing, clean the door frames with hot soapy water and paint any bare wood areas. Why not take the opportunity to oil the hinges and locks as well, before you clean up the door to keep everything working smoothly.
Step 1: Fitting a brush strip draught excluder
Hold the brush strip against the inside of the door and mark the length required to fit from edge to edge.
Cut through the metal and bristle excluder with a hacksaw and crimp the bristles with pincers to stop the ends fraying.
Fix the strip to the bottom of the door with the screws provided. Make sure the bristles push down on to the floor below the door.

Step 2: Fitting foam strips
You can draught proof the edges and top of the door by fitting foam strip around the frame.
Wash the frame with soapy water, then press self-adhesive rubber or foam strip into place once the paintwork has dried.
TOP TIP: To find any gaps that may need an extra layer of draughtproofing strip, run the back of your hand around the door edge to feel for 'cold spots' after you've applied one layer of the strip.
Step 3: Fitting extras
If your door continues to be draughty, it's worth fitting an escutcheon plate to cover the keyhole.
TOP TIP: Adding an inner letterbox flap will also cut down on draughts.
