Winter Storm House Prep: Heat, Food, Water, Sanitation
Get the house ready for ice, snow, frozen pipes, and multi-day winter outages before the first hard freeze.
Quick answer
How do I prepare my house for a winter storm?
Before the first freeze: pick one room you can keep warm safely, stock water in case pipes freeze, hold a week of food that needs little cooking, and stage lighting and batteries. Protect pipes by dripping faucets and opening cabinet doors in hard cold, and know your water shutoff valve.

Heat zones: shrink the house
You cannot heat a whole house without power, and you do not need to. Pick the warm room now: small, few windows, ideally south-facing. In an outage, everyone lives there, doors closed, blankets rolled against the gaps.
Body heat, candles-worth of cooking heat, and closed doors keep one room livable long after the rest of the house goes cold.
Safe indoor heat and cooking
The winter outage rule is the blackout cooking rule with higher stakes: only devices rated for indoor use, only the fuel they name, a window cracked, and a battery carbon monoxide alarm in the room.
Never heat with the gas oven. Never burn charcoal inside. If a fuel heater is not clearly indoor-rated, it heats the porch, not the bedroom.
Carbon monoxide deaths spike in winter outages. Alarm on every sleeping floor, fuel devices per their label, generator outside and 20 feet from openings.
Water when the pipes freeze
Frozen pipes cut water off as surely as a main break, and burst pipes are worse. Store the same 1 gallon per person per day, 2 weeks if you can, before winter locks in.
On hard-freeze nights: drip the faucets farthest from the meter, open cabinet doors under sinks on exterior walls, and keep the house above 55 degrees. Know the main shutoff now, because a burst pipe floods a house in minutes.

- 2Store water before the season: 1 gallon per person per day.
- 3On freeze nights, drip far faucets and open sink cabinets.
- 4If pipes freeze, shut the main and thaw slowly. No open flames on pipes.
The winter food plan
Cold plus cooking limits means the food plan leans on soups, stews, and add-hot-water meals: warm calories with one pot and one fuel can. Hot drinks count double for morale in a cold house.
Hold a week of it. Winter outages in ice-storm country routinely run 3 to 7 days.
Sanitation and hygiene when water is off
If pipes freeze or the supply fails, the toilet becomes the urgent problem. A camping toilet or a bucket with heavy liners and something absorbent (kitty litter works) covers a family for days. Store trash bags, wipes, and hand sanitizer with it.
You can also flush a standard toilet by pouring a bucket of non-drinking water into the bowl. Snowmelt is fine for this.
The 24-hour freeze-readiness check
When the forecast turns, run one lap: water stored, batteries charged, fuel counted, cars fueled and windshield fluid topped, medications filled, and the warm room staged with blankets and lights.
The printable checklist in the download is this lap in order, so anyone in the family can run it.

Common questions
At what temperature do pipes freeze?
Pipes in unheated or exterior spaces are at risk once outside air holds below about 20 degrees Fahrenheit, sooner with wind. Dripping faucets and open cabinets buy protection because moving water resists freezing.
Is it safe to sleep with a fuel heater running?
Follow the device label exactly. Many indoor-rated units are not rated for unattended or sleeping use. The safer routine: heat the room before bed, shut the device off, and rely on bedding overnight.
How do I keep the fridge food cold in winter?
Winter gives you a free option: sealed coolers outside or in an unheated garage act as a fridge when temperatures hold below 40. Keep food sealed against animals, and use a thermometer.
What goes in the car for winter?
Blankets or sleeping bags, ration bars, water (stored where it will not burst if frozen), a shovel, traction sand or mats, a flashlight, and a charged power bank. If you slide off a road in a storm, stay with the car.
