Winterizing Your French Property: A Complete Off-Season Checklist

Published June 5, 2026 · ConciergeService.fr

A single frozen pipe can cause tens of thousands of euros in damage. For foreign property owners who leave their French homes empty during winter months, proper winterization is not optional — it is essential. Our concierge team provides a complete winterization service, from draining systems to arranging regular property checks throughout the cold season.

1. Plumbing and Water Systems

• Drain all water pipes and heating systems
• Add antifreeze to toilet bowls, sink traps, and shower drains
• Shut off the main water supply at the street valve
• Insulate exposed pipes in unheated areas (garage, cellar, outdoor connections)

2. Heating and Utilities

• Set thermostats to 10-12°C (frost protection mode)
• Turn off gas at the mains if the property will be empty for more than 3 months
• Unplug all electrical appliances to prevent surge damage
• Consider installing a remote temperature monitor that alerts us if temperatures drop dangerously low

3. Storm and Security Protection

• Close and lock all shutters (volets)
• Clear gutters and drains of autumn leaves to prevent overflow and water ingress
• Secure outdoor furniture, garden equipment, and terrace items
• Arrange for someone local to check the property after major storms — our concierge service does exactly this

4. Insurance Considerations

• Verify your policy covers damage from frozen pipes during unoccupied periods
• Some insurers require weekly inspections — we can document these for you
• Photographic evidence of winterization can be crucial for claims
