Plumbing and Water Systems
The single greatest risk to an unoccupied home in winter is water damage from frozen pipes. Proper winterization starts with the plumbing system.
- Shut off the main water supply and drain all lines, including outdoor spigots, irrigation systems, and any outbuildings with water connections.
- Add antifreeze to all drain traps, toilets, and any standing water in the system.
- Insulate exposed pipes in crawl spaces, garages, and unheated areas.
- If the home has a well system, ensure the pump and pressure tank are properly winterized or maintained at a safe operating temperature.
- Consider installing a water leak detection system with remote alerts so you are notified immediately if moisture is detected.
Heating and HVAC
Even if you are not occupying the home, the heating system needs to run. Letting a home freeze is never the answer. The goal is to maintain a consistent interior temperature that prevents pipe freezing and moisture problems without running up excessive utility bills.
- Set thermostats to a minimum of 55 degrees Fahrenheit throughout the home.
- Have the furnace or boiler serviced before the season. A mid-winter breakdown in a vacant home is a serious emergency.
- If the home uses propane, schedule a fill before winter and arrange for automatic delivery.
- Install a remote temperature monitoring system. If the heating system fails, you need to know within hours, not weeks.
- Check that all vents and returns are unobstructed.
Roof, Gutters, and Exterior
Heavy snow loads are a real concern in North Idaho, particularly for homes at higher elevations near Schweitzer or in the Selkirk range.
- Have the roof inspected before winter. Look for damaged shingles, flashing issues, and areas where ice dams tend to form.
- Clean all gutters and downspouts. Clogged gutters cause ice dams, which cause water intrusion.
- Trim back any tree branches that overhang the roof or could fall under snow weight.
- Arrange for snow removal if accumulation exceeds safe levels. Know the load capacity of your roof.
- Check exterior caulking around windows and doors. Cold air infiltration leads to condensation and mold.
Security and Access
A vacant home in winter needs to look occupied and remain accessible for inspections and emergencies.
- Set interior lights on timers or smart switches to simulate occupancy.
- Ensure the driveway and walkways are plowed regularly so the property does not appear abandoned.
- Verify that all locks, security systems, and cameras are functioning.
- Provide a trusted local contact with access to the property in case of emergency.
- Confirm that your insurance policy covers extended vacancy. Many policies have exclusions for homes left unoccupied beyond 30 or 60 days.
The Value of Professional Oversight
Winterizing is not a one-time task. It is an ongoing process of monitoring, maintenance, and rapid response. A professional estate concierge performs scheduled inspections throughout the winter, checking for ice dams, verifying heating systems, monitoring snow loads, and coordinating vendors when issues arise.
The cost of professional winter oversight is a fraction of what a single undetected problem can cost. For second-home owners who are hundreds or thousands of miles away, it is not a luxury. It is a necessity.
