Start here
The first-winter short list
- Identify outdoor water lines and ask how your home's hose-bib or irrigation setup should be protected before freezing weather.
- Arrange annual heating-equipment and chimney service with a qualified professional where applicable.
- Test smoke alarms and carbon monoxide detectors; confirm backup batteries and detector placement follow safety guidance.
- Set aside outage essentials for your household, including medications, pet needs, lights, batteries, and local alerts.
Before the first hard freeze: protect water lines
Start with plumbing that is exposed to outdoor temperatures or is not used through winter. The University of Minnesota Extension's winter safety guidance recommends draining and shutting off pipes that are not used frequently in winter, especially lines leading outside.
Walk the water-line route
- Find outdoor hose connections and identify which rooms, crawlspaces, garages, or utility areas have plumbing near unheated spaces.
- Ask a qualified plumber how to protect your particular hose-bib supply lines and any outdoor irrigation system; layouts and winterization steps differ.
- If a pipe freezes, leaks, or bursts, contact a qualified plumber promptly rather than attempting unfamiliar repairs.
Before heating becomes routine: make safety the first setting
Fuel-burning equipment and portable heaters deserve more than a quick glance. The U.S. Fire Administration's heating guidance calls for annual professional cleaning and inspection of heating equipment and chimneys.
Book, test, and clear
- Schedule the annual inspection or service your heating system and fuel type require; use a qualified professional for gas, electrical, venting, or chimney work.
- Test smoke alarms and carbon monoxide detectors and follow their manufacturer instructions for placement, batteries, and replacement.
- Keep anything that can burn at least three feet from a heat source. Turn portable space heaters off when leaving the room or going to bed.
- Never use an oven or stovetop to heat the home.
Before the cold settles in: notice drafts, then choose a sensible fix
Ready.gov recommends preparing the home against cold with insulation, caulking, and weather stripping. Start by noticing where drafts are uncomfortable. The U.S. Department of Energy explains that air sealing must be balanced with ventilation for combustion appliances; get advice from a qualified weatherization professional for larger projects.
A low-drama envelope check
- On a windy day, notice obvious drafts around doors and windows and check whether existing weather stripping is loose or damaged.
- Use an appropriate weather-stripping or caulking repair for a small, familiar gap; do not block equipment vents or combustion-air openings.
- If the fix involves attic, wall, roof, or mechanical-system work, pause and ask a qualified professional rather than sealing by guesswork.
Before the first winter storm: make an outage plan
A few household decisions are easier to make before the forecast turns urgent. Ready.gov recommends having supplies for a possible multi-day stay at home and accounting for medications and pets.
Keep essentials easy to find
- Set aside flashlights or battery-powered lights, spare batteries, warm layers, and a way to receive local weather and emergency alerts.
- Plan for household medications, medical devices, children, and pets if heat or power is interrupted.
- If using a portable generator, operate it outdoors at least 20 feet from windows, doors, and attached garages; follow the manufacturer's instructions and keep working carbon monoxide detectors in the home.
- Do not run generators or grills indoors, and do not use a gas oven or stovetop for heat.
Keep winter prep separate from the year-round routine
This checklist is a seasonal readiness pass, not a replacement for your recurring maintenance plan or move-in setup. Use the guide that matches the job instead of rebuilding your whole calendar here.
Choose the next useful guide
- For recurring monthly and seasonal maintenance, continue with the first-year home maintenance checklist.
- If you are still learning the house and its emergency shutoffs, start with the first 30 days after buying a house checklist.
- For manuals, warranties, service notes, and model numbers, use the home maintenance binder checklist.
