The First Utility guide to draught-proofing your home

Draught-proofing your home means keeping warm air in and cold air out to save both energy and money – and you can even do it yourself.

What to draught proof

You should essentially draught-proof any unwanted gaps in the construction of your home. Just be careful to not block areas of ventilation such as open flues and bathroom vents.

Common draughty areas include:

  • Windows
  • Doors – including letter boxes and keyholes
  • Skirting boards
  • Inactive chimneys and fireplaces
  • Loft hatches
  • Ceiling to wall joints
  • Cracks in walls
  • Pipework leading outside

Draught proofing materials:

Windows and loft hatches

  • Choose between foam, metal or plastic strips. Metal and plastic strips usually have brushes attached and are long-lasting but more expensive.
  • For sash windows, brush strips are best and silicon sealant is great for windows that don’t open.

External doors and doors leading to unheated rooms

  • Install a brush or flap to your letterbox and a purpose-made drop disk to your keyhole
  • Use a draught excluder made using bristles or a hinged flap
  • Just the same as windows, fill gaps around the door with foam or brush strips.

Skirting boards

  • Squirt a silicon-based filler into any gaps between skirting boards and floorboards


  • Insulate around pipework with a silicon filler, just like you would insulate your skirting boards. For larger gaps, opt for expanding polyurethane foam.

Unused chimneys and fireplaces

  • Insert a chimney draught excluder or have a professional install a cap over the chimney pot.

Small cracks in walls

  • Fill using cement or hard-setting fillers. Larger cracks may require professional advice.

Draught-proofing costs and savings

According to the Energy Saving Trust (EST), draught proofing your home professionally could cost up to £400. If you can do it yourself, you can complete your home for around £100.

EST figures also show that draught-proofing around windows and doors could save you £50 a year on your heating bill. With heat being kept inside, owners of draught-free homes are more likely to turn their heating down a notch. Turning down your thermostat by just one degree could save you an average of £75 a year*.
