Seasonal Checklist: Preparing Your Home and Yard for a Harsh Winter Storm Season

The storm that knocks out power for three days rarely sneaks onto the calendar. What catches most households off guard is the small stuff: the gutter that tears loose under a load of ice, the pipe that splits inside an exterior wall, the generator that won't start because it sat since March with old fuel in the tank. A few hours of work on a mild weekend in late fall can spare you a very long week in January.

Start With Gutters and the Roof

Winter water damage almost always begins above your head and works its way down. Before the first hard freeze, clear leaves, twigs, and shingle grit out of the gutters and confirm that every downspout actually drains. A downspout that empties right at the foundation pours meltwater into the same soil your basement wall sits against.

While someone is up there, look for lifted or missing shingles, cracked sealant around chimney flashing, and the rubber boot around the plumbing vent pipe. Small openings let in wind-driven rain and snow, and freeze-thaw cycles widen them. If your roof is steep, above the second story, or you simply don't like ladders, hire it out. A fall costs far more than a cleaning.

Ice dams are an attic problem, not a roof problem

Ice dams form when heat escaping your house melts snow on the upper roof, which refreezes at the cold eaves and backs water up under the shingles. The fix is boring and effective: more insulation, better ventilation, and sealing air leaks around attic hatches, light fixtures, and ductwork. Never climb onto a snowy roof to chip ice with an axe or hammer. A roof rake used from the ground, kept well clear of overhead wires, is the safer tool.

Keep Meltwater Moving Away From the House

Gutters get the attention, but grading and drainage decide whether that water ends up in your basement. Walk the perimeter and look for soil that slopes back toward the foundation. A few wheelbarrows of dirt packed along the wall so the ground falls away instead of toward it does more than any tube of sealant you can buy.

Clear window wells of leaves and debris, and check that sump pump discharge lines run well away from the house, not into the corner where they'll freeze and re-flood. When you shovel, push snow away from the foundation and away from basement windows. Those piles are next spring's water.

Pipes: The Most Expensive Thing You'll Forget

Every winter, the same pipes burst: the outdoor spigot, the line running through an unheated crawlspace or garage, the sink on an exterior wall. All three are cheap to protect and expensive to repair.

• Disconnect garden hoses and drain them. A hose left attached traps water in the spigot, where it freezes and splits the pipe behind the wall.
• Shut off and drain outdoor spigots from the inside valve if your system allows it.
• Insulate pipes in crawlspaces, garages, attics, and along exterior walls with foam sleeves, and add UL-listed heat cable where pipes are most exposed.
• On the coldest nights, open cabinet doors under sinks on outside walls so warm room air reaches the pipes.
• Let a pencil-thin trickle run from the faucet farthest from where water enters the house.
• Find your main water shutoff now, label it, and make sure everyone in the house knows where it is.

If a pipe does freeze, warm it gently with a hair dryer or towels soaked in hot water, starting at the end nearest the faucet. If it has already split, shut off the main and call a plumber before you turn anything back on.

If you're leaving town for a stretch

Don't shut the heat off. Keep the thermostat set no lower than about 55°F, leave cabinet doors open, and ask a neighbor to check the house after the worst nights. If you'll be gone for weeks, have a plumber drain the system properly before you leave rather than dealing with the results afterward.

Yard, Trees, and Anything That Becomes a Projectile

Winter wind turns loose objects into damage. Store or anchor patio furniture, grills, planters, garbage cans, and anything light enough to lift. Take down the trampoline net or stake the frame, and coil hoses indoors so they don't crack.

Look up before you look down. Dead limbs over the driveway, the power line, or the spot where you park are a storm's easiest targets. Anything near utility lines is a job for the utility or a licensed arborist, never for a homeowner with a chainsaw. For everything else, a late-fall pruning removes the obvious hazards.

Plants need prep too. Wrap young or marginally hardy shrubs in burlap to block wind and road salt, water evergreens deeply before the ground freezes, and spread mulch after the first hard frost. When you shovel, toss snow gently around shrubs instead of dropping a heavy load on top of them. Restock shovels, a roof rake, sand, and ice melt before the first forecast, when shelves empty in an afternoon. Skip rock salt on new concrete and use sand for traction.

Build an Emergency Kit Around an Actual Outage

A winter outage means no lights, no heat, no well pump, and often no card reader at the one gas station that's open. Build for three days at minimum, and keep it all in one place you can reach in the dark.

• Water: one gallon per person per day, plus water for pets
• Nonperishable food, a manual can opener, and a way to heat food that doesn't need electricity
• Flashlights and headlamps with spare batteries; skip candles for anything but decoration
• A battery or hand-crank weather radio, and fully charged phone power banks
• First aid kit and a week of medications
• Blankets, sleeping bags, hats, and gloves for every person
• Small bills in cash
• Copies of insurance, medical, and contact information in a waterproof bag

Ask your pharmacist how long any medication can safely go without refrigeration, and talk with your doctor before the season about backup plans for medical equipment that needs power. Those conversations are easier in October than during a storm.

Cars, Generators, and Heat Sources

Keep your gas tank at least half full through the winter and pack the trunk: blanket, gloves, flashlight, scraper, jumper cables, sand or kitty litter for traction, phone cable, and a snack. If you're stranded, stay with the vehicle and run the engine only long enough to warm up, with the tailpipe cleared of snow.

Generators and space heaters cause a large share of winter emergencies. A generator runs outdoors only, never in a garage, breezeway, or attached space, even with the door open. Keep space heaters at least three feet from anything that burns, plug them directly into a wall outlet rather than an extension cord, and turn them off when you leave the room or go to sleep.

A Weekend Walkthrough That Takes Three Hours

None of this is difficult. It's just easy to postpone. Pick a dry Saturday in late fall and work through it in order.

1. Walk the perimeter: gutters, downspouts, grading, window wells.
2. Insulate and drain: spigots, hoses, exposed pipes, main shutoff labeled.
3. Secure the yard: furniture, planters, dead limbs, tools, shovels and ice melt staged.
4. Check the kit: batteries, water, medications, cash.
5. Prep the car, and confirm the generator and heaters are ready and safely placed.

While you're at it, knock on the door of the neighbor who lives alone or has a hard time shoveling. Winter storms are less dangerous on streets where people check on each other. That habit, more than any checklist, is what gets a block through a bad week.
