Deal with unwanted gaps around doors, windows and floors while preserving intentional ventilation. Do not block air bricks, trickle vents, flues or ventilation needed by appliances. A warmer home still needs a way to remove moisture and maintain air quality. If you are unsure what an opening does, identify it before sealing it.
Join the discussion: Where is the draught coming from, and are there any fuel-burning appliances nearby?
Suggested next step: Start with a draught assessment; seek suitable professional advice for appliance ventilation.
