Winter Is Coming to Louisiana — Is Your Home Ready? A Complete Cold-Weather Checklist

Our Louisiana homes are built for heat and humidity, not ice. Plumbing runs through attics, crawl spaces, garages, and exterior walls — places that never see warm air. That's why one hard freeze here can do more damage than a whole winter up north. The good news: most freeze damage is preventable with one Saturday morning of prep. And the time to do it is now, before the first real cold snap — not the night the freeze warning hits and every hardware store in town is sold out of faucet covers.

Protect your pipes first

Know where your main water shut-off valve is, and make sure it turns. If a pipe ever bursts, shutting the water off in minutes instead of an hour is the difference between a mop job and a major claim.
Insulate every exposed pipe you can find — under a raised house, in the attic, in the garage, along exterior walls. Foam sleeves from the hardware store are cheap and take minutes to install.
Cover outdoor faucets with insulated foam covers, and disconnect your garden hoses. A hose left attached traps water in the faucet and can split the pipe inside the wall.
When a freeze is forecast: let one faucet trickle slowly overnight — the one farthest from where water enters your house works best — and open the cabinet doors under sinks on exterior walls so warm air can reach the pipes.
Never thaw a frozen pipe with a torch or open flame. If you turn on a faucet and nothing comes out, shut off the main and call a plumber.

Your irrigation system and pool

Sprinkler backflow preventers sit outside with water in them and are one of the most common freeze casualties in Louisiana. Shut off the irrigation water, drain the backflow at its small drain valves, and wrap it in insulation.
For pools: during a short freeze, keep the pump running so water circulates — moving water doesn't freeze as easily. For a long hard freeze, follow your equipment maker's drain-down instructions.

Plants and the yard

Water everything well the day before a freeze. Hydrated plants handle cold far better than dry ones, and moist soil holds heat.
Cover tender plants with frost cloth, old sheets, or blankets, anchored with stakes or stones so the cover reaches the ground and traps the soil's warmth. Don't let plastic touch the leaves.
Bring tropical potted plants — hibiscus, mandevilla, palms in pots — into the garage or house. If a pot is too big to move, push it against the house under an eave and cover it.
Add a loose layer of mulch or pine straw around the base of in-ground plants to insulate the roots.
Citrus trees: cover them when temperatures are expected to stay below freezing for six hours or more.
Leave fountains running during a freeze — circulating water resists freezing.
Don't panic about your winter color: pansies, snapdragons, and ornamental kale are built for Louisiana cold and usually need no help at all.

The house itself

Have your heater serviced before you need it, and replace the filter. The first cold night is when every HVAC company in the parish has a two-day wait.
Check weather stripping around doors and windows, and seal gaps where pipes and wires enter the house — that's where cold air pours in.
Test your smoke and carbon monoxide detectors. Space heaters and fireplaces work hard in a cold snap: keep heaters three feet from anything that can burn, never leave them unattended, and never use an oven or stovetop to heat your home.
Clean the gutters. Clogged gutters overflow against the roofline and fascia, and water damage doesn't care what season it is.
Bring the pets inside. If it's too cold for you outside in a coat, it's too cold for them.

One last thing — the insurance angle

A burst pipe can pour hundreds of gallons into your home before anyone notices, and water damage is one of the most expensive claims a homeowner can file. Most homeowners policies cover sudden pipe bursts — but they expect you to take reasonable care of your home, and damage from a long-ignored leak is a different story. While you're winterizing, take ten minutes to walk through your house with your phone and video your rooms and valuables. If you ever do have a claim, that video is gold.
