Winterizing Your Home: A 4-Weekend Plan Before the First Freeze

One cold night can blacken a bed of tomatoes. The same night can split the outdoor faucet you meant to drain last weekend.

I spread winterizing your home over four weekends, in the order winter breaks things. Garden and water go first. Then garlic and drafts, then heat and safety, and the flock and pantry last. Here’s what to do tonight and what can wait for Saturday.

What breaks first when winter hits your home?

Tender crops and water break first. One night near freezing can kill tomato plants, and that same night can freeze a hose bib or a pipe in a cold garage.

Next comes air leaking out around windows and doors, all winter long. Then the heating gear, which starts working hard the day it turns cold. Here’s what each one does to you, so you know why the order matters.

Tender crops go the first cold night

Frost can form when the air is still 33°F to 36°F, according to the Farmers' Almanac. Tomatoes, peppers, basil, beans, cucumbers, summer squash, and melons all take damage. Kale, cabbage, carrots, and spinach shrug off a light frost.

Water freezes next

Water gets bigger when it freezes. Inside a pipe, that can split the pipe. You usually don’t find out until it thaws and starts leaking into the wall.

Check garages, crawl spaces, and pipes along outside walls. That’s where the trouble starts.

Air leaks cost you all winter

A gap you can barely see around a door leaks heat every day until spring. ENERGY STAR says sealing air leaks and adding insulation can save homeowners an average of 15% on heating and cooling.

Heaters bring their own risks

Furnaces, wood stoves, space heaters, and generators keep you warm. They can also start fires and make carbon monoxide. Check them before you lean on them.

How to plan your winterizing weekends

I tried doing all of it in one weekend once. By Sunday night the caulk gun was still on the porch rail and the attic hatch was still open. Four weekends, one job each, gets it finished.

Start as soon as frost shows up in your forecast. Here’s the order.

Weekend 1: frost night and water

Weekend 2: garlic and drafts

Weekend 3: heat and safety

Weekend 4: the flock and the pantry

What do you need for winterizing your home?

You need frost cloth and seed garlic for the garden, pipe sleeves and faucet covers for water, caulk and weatherstripping for drafts, and working smoke and CO alarms. Most of it costs less than one month of a high heating bill.

Here’s the short list for each weekend. Skip anything you already own. Cheap is fine. Cheap twice isn’t.

For the garden

• Frost cloth. It holds the soil’s warmth over tender plants and lets light and air through, so it can stay on for a cold stretch.
• Landscape staples. They pin the edges so the wind can’t lift the cloth and let the cold under.
• Straw for mulch. It tucks the garlic in for winter. Buy a bale of weed-seed-free straw at a local farm or garden center. Shipping a bale costs more than the straw.
• Seed garlic. Buy it from a local grower or a garlic seed company. Grocery garlic is often treated so it won’t sprout.

Only buying one thing tonight? Make it this. One cloth covers a whole bed of tomatoes and peppers:

For water

• Foam pipe sleeves. They slow heat loss on pipes in cold spots, like the garage or crawl space.
• Outdoor faucet covers. An insulated cap adds a layer over each faucet after you drain it.

Every faucet on an outside wall gets drained, then capped. This two-pack covers a front and a back faucet:

For drafts

• Caulk and a caulk gun. Caulk seals cracks of 1/4 inch or less around trim and frames.
• Foam weatherstripping. It seals the parts of doors and windows that move, where caulk can’t go.
• A door sweep. It closes the gap under the door where cold air rolls in.
• Window and door spray foam. It fills gaps from 1/4 inch up to about 3 inches without bowing the frame.

Start with the door where you can feel the draft. This self-stick foam presses onto the door stop, so the door closes against it:

For heat and safety

• A combination smoke and CO alarm. CO alarms belong on every level of the house and outside each sleeping area. A combo unit covers both jobs in one spot.
• The right furnace filter. Write your filter size on the furnace with a marker. Keep a spare so you can swap it the day it looks dirty.

If all you have today is smoke alarms, add CO protection first. This plug-in model has a battery backup for outages:

For the flock

• A heated poultry waterer. It keeps water open on freezing mornings without a heat lamp in the coop. You’ll need an outdoor-rated outlet near the coop.

If the coop water froze solid last winter, this is the fix. It’s a 2-gallon heated drinker that plugs in:

Tonight’s frost checklist

If your forecast says 32°F or colder tonight, pick what’s ready and cover the rest before sunset. To check your usual frost date, the Old Farmer's Almanac frost date calculator looks it up by ZIP code.

Before dark, this is a 10-minute job. After dark, it’s a cold one with a flashlight in your teeth. Here’s the order.

Before dark

• Pick anything that’s ready: ripe or full-size green tomatoes, peppers, basil, beans, cucumbers, and summer squash.
• If the soil is dry, water it earlier in the day. Moist soil holds more heat and gives it back overnight.
• Before sunset, drape frost cloth, old sheets, or blankets over tender plants. Let the cover reach the ground on every side so it traps the soil’s heat.
• Hold the cover off the leaves with stakes, hoops, or tomato cages. Leaves touching the cover can still freeze, plastic most of all.
• Pin the edges with landscape staples or bricks.

CHECKPOINT: Tender plants picked or covered. Covers touch the ground, not the leaves. Edges pinned.

Overnight and morning

• Leave the covers on all night.
• Pull them off the next day once it’s above freezing, so the plants get sun and air.

Covers buy you a few degrees. That’s all. Iowa State Extension notes that once it drops below about 28°F, covers usually stop working. If the forecast shows a hard freeze, pick everything tender.

Green tomatoes indoors

Pick tomatoes that are full size and turning a pale, greenish white. Iowa State Extension suggests wrapping each one in newspaper and keeping them in a cool, dark spot around 60°F to 65°F. Move them to room temperature once they start to color.

How to plant garlic by zone this month

Plant garlic about 3 weeks before your ground freezes, says the Old Farmer's Almanac. In the coldest zones that means late September to early October. In warmer zones it can run into November.

It’s the one crop you plant while everything else is shutting down, and you dig it next summer. Here’s when to plant where you live, which garlic to buy, and how to tuck it in.

Pick the right garlic

Buy seed garlic from a local grower or a garlic seed company. Iowa State Extension points out that grocery garlic is usually a softneck type from warmer places, and it’s often treated so it won’t sprout. In cold climates, hardneck types usually do better.

Plant the cloves

• Break the bulb into cloves right before planting. Leave the papery skins on. Plant the biggest cloves, since bigger cloves grow bigger bulbs.
• Set each clove pointed end up, about 2 inches deep and 6 inches apart. Space rows 12 to 18 inches apart.
• Cover with soil, firm it gently, and water if the soil is dry.

Let’s measure before we buy. A 4-by-8 raised bed with rows 12 inches apart and cloves 6 inches apart holds about 4 rows of 15. That’s around 60 cloves, or roughly 6 to 10 bulbs, depending on how many cloves each bulb holds.

Tuck it in with straw

Spread 4 to 6 inches of weed-seed-free straw over the bed once the soil starts to freeze. In spring, after hard freezes are done, pull the straw back or move it between the rows.

If you miss the window, UNH Extension says cloves planted very early in spring can still make bulbs, though fall planting is more reliable. For the rest of the season, see our guide to growing garlic at home.

How to protect your pipes from freezing

Drain everything outside, wrap the exposed pipes inside, and keep warm air reaching your plumbing on cold nights. That handles most frozen-pipe trouble.

These steps follow American Red Cross guidance. Start outside, then go inside, then know what to do if a pipe freezes anyway.

Outside: hoses and hose bibs

• Unscrew, drain, and store every garden hose. A hose left on the faucet holds water that can freeze back into the pipe.
• Inside the house, close the shut-off valve that feeds each outdoor faucet.
• Go back outside and open the outdoor faucet so the water left in the line drains out. Leave it open.
• Add an insulated faucet cover.

Here’s the part people skip: finding that inside valve. Mine sits behind the water heater, and the first year I found it with a flashlight and a lot of moving boxes. Find yours now and hang a tag on it.

CHECKPOINT: Hoses stored. Inside valves closed. Outdoor faucets open and drained. Covers on.

Inside: exposed pipes

• Walk the garage, basement, crawl space, and under the sinks. Look for pipes on outside walls or in rooms that don’t get heat.
• Slide foam pipe sleeves over every exposed pipe you can reach. Tape the seams if they gap.
• If a pipe still freezes, a UL-listed heat cable is an option. Follow the instructions exactly. Put it right on the pipe, never on top of insulation, and never wrap it over itself unless the instructions allow it.

STOP POINT: Heat tape that’s worn, cracked, or put on wrong can start a fire. If you’re not sure about yours, unplug it and have a licensed plumber or electrician look at it.

On cold nights

• Let cold water drip from faucets fed by exposed pipes. Moving water is harder to freeze.
• Open kitchen and bathroom cabinet doors so warm air reaches the pipes. Move cleaners up and out of reach of kids and pets.
• Keep the thermostat at the same setting day and night.
• If you’ll be away, leave the heat on, set no lower than 55°F.

CHECKPOINT: Faucets dripping on the coldest nights. Cabinets open. Thermostat steady.

If a pipe freezes anyway

If only a trickle comes out of a faucet, a pipe may be frozen. Keep the faucet open. Warm the frozen spot with an electric heating pad, a hair dryer, a space heater kept away from anything that can burn, or towels soaked in hot water.

STOP POINT: Never use a torch, a propane or kerosene heater, a charcoal stove, or any open flame to thaw a pipe. If you can’t find the frozen spot, can’t reach it, or can’t thaw it, call a licensed plumber.

How to seal drafts around windows and doors

Find the leaks on a windy day, caulk the small cracks, and weatherstrip the parts that move. It’s the cheapest way to a warmer house, and all of it is DIY work.

Measure each gap before you shop. My eyeball has bought more of the wrong weatherstrip than I care to admit.

Find the leaks

On a cold, windy day, hold the back of your hand near the edges of windows and doors, outlets on outside walls, and spots where pipes come through. Wherever you feel a chill, mark it with painter’s tape.

Caulk the small cracks

Caulk works on gaps 1/4 inch or smaller. For bigger gaps, up to about 3 inches, use low-expansion spray foam.

• Scrape out old, cracked caulk. Wipe the spot clean and let it dry.
• Cut the caulk tip at an angle, just big enough to make a bead that fills the gap.
• Run one steady bead along the crack, then smooth it with a damp fingertip.
• Let it cure as long as the tube says before you paint or wash it.

Weatherstrip doors and windows

• Clean the surface where the strip goes.
• Measure each edge, cut the weatherstripping to length, peel, and press it on.
• If you can see daylight under a door, add a door sweep.

CHECKPOINT: Close each door and window. The strip should squish a little, and you shouldn’t feel air or see light.

Curtains, rugs, and draft stoppers

Plastic film on windows stops drafts, but it also blocks the low winter sun. Heavy, lined curtains do both jobs: close them at night and open them on sunny days. Area rugs warm up cold floors. An old sock or sweatpant leg stuffed with fabric scraps makes a free draft stopper for the bottom of a door, and worn-out clothes can become a rag rug.

Does your attic need more insulation?

If you can see the tops of the attic floor joists, you probably need more. Most homes with only 3 to 4 inches should add more, up to about R25 to R49 depending on your climate.

Seal the air leaks first, then add insulation. That order also helps prevent ice dams. Here’s how to check what you have and when to hand the job off.

Check what you have

From the attic hatch, measure how deep the insulation is with a ruler. ENERGY STAR's R-value chart shows the right level for your climate zone: R25 in the warmest zone up to R49 in most of the country, for an attic that already has some insulation.

Step only on joists or a board laid across them. The ceiling between them won’t hold you. Wear gloves, eye protection, and a dust mask, because insulation itches.

Seal before you add

First seal the gaps around light fixtures, pipes, and wires that come up through the attic floor. Insulation piled over open gaps lets warm, damp air keep leaking through.

Stop ice dams at the source

Ice dams are thick ridges of ice at the edge of the roof. University of Minnesota Extension explains they’re mostly caused by heat leaking out of the house and warming the roof. The fix follows the same order: seal the ceiling, add insulation, then check ventilation.

STOP POINT: If you see old cloth-covered wiring, damaged wires, or anything you can’t identify in the attic, stop. Call a licensed electrician or insulation contractor before you disturb it. This is where the DIY part stops.

How to get heat and safety gear ready

Check the furnace filter, book a yearly inspection for anything that burns fuel, and test every smoke and CO alarm. Then make a plan for space heaters and power outages.

These checks keep a warm house a safe one. Go system by system.

Furnace

ENERGY STAR says to check the filter every month in winter, change it if it looks dirty, and change it at least every 3 months. A yearly professional tune-up keeps it running well.

Chimney, fireplace, and wood stove

Have a qualified professional clean and inspect your chimney, vents, and heating equipment every year. Keep anything that can burn at least 3 feet from any heat source, a guideline from NFPA.

Smoke and CO alarms

Press the test button on every alarm once a month. Put CO alarms on every level of your home and outside each sleeping area.

CHECKPOINT: Every alarm beeped when tested. A CO alarm sits on every level.

Space heaters and generators

CPSC gives the rules:

• Plug space heaters straight into a wall outlet, never an extension cord or power strip.
• Turn heaters off when you go to sleep.
• Run a portable generator outdoors only, at least 20 feet from the house, with the exhaust pointed away.
• Never run a generator inside your home, basement, shed, or garage, even with the door open.

STOP POINT: Carbon monoxide has no smell. If a CO alarm sounds, or anyone feels dizzy, sick, or confused, get everyone outside right away and call 911. If you smell gas, leave first and call 911 or the gas company from outside.

How to winterize your backyard coop

Keep the coop dry, block drafts at roost level, leave vents up high, and keep the water from freezing. The coop doesn’t need a heater.

Damp air, drafts, and fire risk cause more coop trouble than cold does. Here’s what to fix on the building and what to skip.

Dry and draft-free, not heated

Block drafts at roost height, but leave vents near the roof so moisture can get out. Add fresh, dry bedding. UNH Extension warns against heat lamps: with dry bedding and birds knocking things over, the fire risk is too high.

Keep water from freezing

Chickens need clean, unfrozen water all day. Use a heated poultry waterer, or swap in a rubber bucket of fresh water a few times a day. Set the waterer on a block or stand so bedding doesn’t get kicked into it.

For the birds themselves, see how to keep your chickens warm in winter. For goats and bigger animals, see our livestock and barn winter tips.

What should you stock up on before winter storms?

Water, food your family already eats, and the basics for a power outage. The Red Cross suggests one gallon of water per person per day, with a two-week supply at home.

A backup system doesn’t need to be fancy. It needs to work on the third day the road isn’t plowed. Here’s what to cover.

Water and food

Plan backward from what your family really eats in two weeks: soups, beans, rice, oats, canned goods, and anything you’ve put up yourself. Keep a simple list so the oldest items get used first.

Cool storage that won’t freeze

Potatoes, squash, and apples keep well in a cool closet or garage corner, but only if it stays above freezing. Home-canned jars need the same: cool, dark, and dry. Our guide to canning the fall harvest covers what to can and what to store whole.

Power-outage basics

Flashlights, extra batteries, warm blankets, a charged power bank for phones, and a battery radio. Keep them in one bin where anyone in the house can find it in the dark.

Paths and ice melt

Clear sticks and rocks off the paths before the first snow buries them. Keep ice melt or sand where you can grab it. Go easy on salt where pets walk, since it can irritate their paws.

Troubleshooting winter home problems

Most winter problems show an early sign first. Catch it then and the fix stays small.

Here’s what to look for and what to do.

Common internet shortcuts to avoid

Winter brings a wave of quick fixes online. Some are harmless. These can kill a garden, start a fire, or make someone sick.

Here’s what to do instead.

Plastic sheeting right on the plants

Plastic touching the leaves passes the cold straight through. Use frost cloth or old sheets, and hold any cover off the leaves.

Planting grocery-store garlic

Store garlic is often treated so it won’t sprout, and it may not suit your climate. Plant seed garlic from a grower.

A heat lamp in the chicken coop

Dry bedding, dust, and birds that knock things over make a heat lamp a real fire risk. Block drafts and keep the water open instead.

Thawing pipes with a torch

An open flame can start a fire inside the wall. Use a hair dryer, a heating pad, or hot towels, or call a plumber.

Running a generator in the garage

Carbon monoxide builds up fast in a garage, even with the big door open. Generators go outdoors, at least 20 feet from the house.

When to call a pro

Most winterizing is DIY work. A few jobs belong to licensed pros, and knowing which ones saves you from doing them twice.

Call for help when:

• You smell gas or a CO alarm sounds. Get out first, then call 911 or the gas company.
• A pipe is frozen where you can’t reach it, or it has burst. Shut off the main water and call a licensed plumber.
• It’s time for the yearly check. Furnaces, chimneys, wood stoves, and other fuel-burning equipment need a qualified pro every year.
• You find damaged or old wiring in the attic. Call a licensed electrician before you add insulation.
• You need a new outdoor outlet for a heat cable or waterer. That’s an electrician’s job.

Buy once: winter home gear

Frost cloth, draft-proofing, and safety gear for winterizing your home last for years if you buy the right thing once. Thin foam strips peel off by January and get bought again.

Here’s how the options stack up.

After the first hard freeze

Winterizing your home gets one more pass once real cold sets in. Ten minutes covers it:

• Check faucet covers after wind or snow. Push any loose ones back on.
• Pull back the straw and look at the garlic bed once. Press down any cloves that heaved up, then re-cover.
• Check the furnace filter on the first of each month, the same day you test the alarms.
• Look at the ceiling near the roof edge after each big snow. A new stain means ice is backing up.

That’s the job. Questions people ask most are below.
