Quick fixes around the house

  • Tighten loose hinges, catches and latches. If doors or windows don't fit their frames snugly, you might need repairs by a qualified builder.
  • Add weather stripping. Your hardware store can advise you on which product to use to seal gaps around doors and windows.
  • Seal door and window trims. Use a clear or paintable sealant to make them weather resistant.
  • Fit draught excluders. Use a brush strip type for internal doors, and spring loaded automatic seals for external doors.
  • Replace damaged rubber seals around aluminium joinery. You can do this yourself with the right-sized rubber or hire a professional.
  • Check the ceiling hatch. Make sure it fits correctly and use weather stripping to seal it.
  • Seal skirting boards and cornices. Use flexible silicon-based or latex sealants, or take them off to block gaps with expanding foam.
  • Block an unused chimney or fireplace. Use a rubbish bag filled with shredded newspaper. Just make it obvious the chimney is blocked, so no-one tries to light a fire.

  • Install underfloor insulation. This will reduce draughts through floorboards and reduce heat loss through the floor.

Seal gaps around wiring and plumbing

Gaps around these passages are often hidden – so look behind kitchen and bathroom cabinets, inside hot water cupboards and wardrobes.

  • Use silicone sealants for smaller gaps and expanding foam for bigger gaps.
  • Check extractor fans and rangehoods. If they have shutters, check they work properly.
  • Check recessed downlights for draughts. You can replace them with new ones that better sealed and can be covered with insulation – ask for IC, IC-F or IC-4 LED downlights.

Create a warm, dry environment

  • Heating

    To prevent mould growth, rooms should be heated to at least 18˚C.
