Draught Proofing your Home

Draught-proofing is one of the many cheap and efficient ways to save energy and money in any type of home.

Draught-proofing is one of the many cheap and efficient ways to save energy and money in any type of home. Good ventilation helps reduce condensation and damp, but draughts are uncontrolled; they let in too much cold air and allow loss of heat. By ensuring there are no draughts in your home, the warm heat will remain which means less energy will be used to heat your home.

Where to look and prevention

Draught-proofing your home can be quick and easy, you just need to know where to start. To help find draught areas in your home look near the following areas:

  • Windows: Self-adhesive foam strips and metal/plastic strips are available to stick around the windows to help cover gaps between the window and the frame.
  • Doors: Inside doors - if you don’t normally heat rooms where these doors lead to, you may need draught-proofing - it's important to keep these doors closed and use a draught excluder, if there's a gap at the bottom. Draught-proofing outside doors could lock heat in and wont cost much, it's important to consider the following:
  • Keyholes: Buy a purpose-made keyhole cover
  • Letterboxes: Use a letterbox flap or brush
  • Gaps at the bottom: Use a brush or hinged flap draught excluders
  • Gaps around the edges: You could fit foam, brush or wiper strips
  • Loft hatches: Block off draughts around the hatch to reduce the heat loss and you can use strip insulation like you can on doors
  • Electrical fittings on walls and ceilings
  • Suspended floorboards
  • Pipework leading outside: Small gaps around small pipes can be filled with silicone filler and larger areas can be filled with expanding polyurethane foam
  • Ceiling-to-wall joints
  • Old extractor fans: These can be filled with brick or concrete and sealed from both sides
  • Cracks: Use cements or hard-setting fillers to fill in small cracks in your wall around your home. If there's a large crack you may need to consult a surveyor or builder to find out the cause
  • Chimneys and fireplaces: If your chimney's not in use, it's likely to be a source of draught. To draught-proof your chimney you can purchase a chimney draught excluder, which tends to be fitted within the chimney or around the fireplace or you could fit a cap over the chimney pot.
  • Floorboards and skirting boards: Use a silicone based filler which can tolerate movement, as this type of wood will contract and expand with every day movement.

How much could you save?

Draught-proofing your home could save you around £20 per year. When homes are draught-proofed, they hold more heat in for longer so you may feel comfortable at a lower temperature which may save you money.

You may wish to carry out your own draught-proofing or you could hire a professional costing around £200.

If you're unsure of the materials to use or you have single glazing you may prefer to hire a professional, this may save more energy as the installer will know the correct material to use for each job. If you do decide to carry out this work yourself, always look for draught-proofing with a Kite mark.
