Overview

What is draught sealing?

Draughts are currents of air that move in and out of your home through gaps around doors, windows, floorboards, skirting boards, vents, exhaust fans, and where pipes and cables pass through walls. Draught sealing seals these gaps using materials such as weather strips, door seals, gap fillers and vent covers, so less of your warm or cool air escapes.

It is a simple, low cost way to make your home more comfortable and cut your heating and cooling bills. Through Home Energy Saver, a qualified installer carries out the sealing work for you.

Some ventilation is needed for safety. Vents serving unflued gas heaters or other appliances that need airflow are not sealed, and your property assessment confirms what can be sealed safely.

Is it right for your home?

Draught sealing may suit your home if you:

  • feel draughts around doors, windows or vents
  • have an older home with gaps or unsealed vents
  • want a low cost way to improve comfort and cut heating and cooling bills

Draught sealing is carried out as sealing work rather than chosen from a product list. The exact works for your home are confirmed at your property assessment.

Function

How it works

Find the gaps

Draughts enter through gaps around doors, windows, vents, floors and where pipes and cables pass through walls.

Seal them

A qualified installer seals the gaps with weather strips, door seals, gap fillers and vent covers.

Keep safe airflow

Vents serving unflued gas heaters or appliances that need airflow are left unsealed for safety.

Stay comfortable

Less warm or cool air escapes, so your home stays comfortable for less.
