Cold weather creates the most expensive home emergencies: burst pipes, heating system failures, ice dam damage. Most are preventable. Complete this checklist in October-November, before temperatures drop.
Heating system prep
Do these before the first cold snap:
- ✓Replace furnace filter
- ✓Test the thermostat by running heat for 15 minutes
- ✓Check that all supply registers are open and unobstructed
- ✓Schedule professional heating tune-up
- ✓Test carbon monoxide detectors and replace batteries
- ✓Stock up on air filters for the season
Pipe and plumbing winterization
Frozen pipes cause $5,000-$70,000 in damage when they burst:
- ✓Disconnect and drain all outdoor hoses
- ✓Shut off and drain outdoor hose bib supply lines if temperatures drop below 20°F in your area
- ✓Know where your main shutoff is
- ✓Insulate any pipes in unheated spaces (garage, crawlspace)
- ✓Keep cabinet doors under sinks open during extreme cold snaps
Roof and exterior
Set your home up for winter weather:
- ✓Clean gutters after leaves have fallen completely
- ✓Inspect roof for missing or damaged shingles before snow loads add weight
- ✓Check attic insulation and ventilation (poor ventilation causes ice dams)
- ✓Caulk any gaps in the exterior before cold air locks caulk in place
Emergency prep
Be ready if systems fail:
- ✓Know how to shut off water, gas, and electricity
- ✓Have a backup heat source plan (space heater, fireplace, or hotel plan)
- ✓Stock flashlights with fresh batteries
- ✓Keep at least 2 days of water on hand
Bottom line
The cost of winterizing your home is measured in hours and hundreds of dollars. The cost of not winterizing can be measured in tens of thousands. Do it in October.
