- Ensure there are no gaps in insulation or crawl spaces that expose pipes to cold air, which could put the pipes at risk of freezing and bursting.
- Have your heating system checked by a licensed technician before cold weather requires daily use.
- Block drafts around doors, windows and baseboards with weather stripping, window film and caulk to control heat loss.
- Install storm doors and windows to improve energy-efficiency and get rid of drafts.
- Have chimneys cleaned by an experienced chimney sweep to prevent the risk of a fire from buildup or blockages.
- Spray door locks with powdered-graphite lubricant to prevent freezing and sticking.
- Set ceiling fans to rotate clockwise to force rising warm air back towards the floor.
