How to Prepare an Old House for Winter [21+ Things to Check]

Last Updated on September 30, 2026

I love the fall season, the changing leaves, the cozy rooms, the fireplace. But then the temperature drops. And suddenly you notice that one window is really drafty. The upstairs bedroom is freezing. The basement pipe looks a little too exposed. And in the middle of ice storm, you’re wondering if you should have done something about that right gutter three months ago.

What I have learned after living in old houses for 20 years is how how to prepare an old house for winter doesn’t mean you need to fix every quirk, draft, and imperfection before the first snowflake falls. Instead, focus on the things that have the largest impact and can cause water damage, frozen pipes, heating problems, or unnecessary heat loss.

This guide walks through 21+ things to check before cold weather arrives, with special attention to the quirks and challenges that come with owning an older home.

How to Prepare an Old House for Winter: Start With These Four Priorities

If your fall to-do list is already a mile long, don’t panic. When you’re figuring out how to prepare an old house for winter, I like to think about four basic priorities:

Keep water out
Keep heat in
Protect pipes and heating system
Find small problems before winter makes them bigger problems

Let’s start outside the house and work our way in.

1. Clean Your Gutters

Yes, I know. Cleaning gutters is not exactly exciting. I’m actually afraid of heights so I hire someone to do it. Related Post: [Hiring a Gutter Cleaning Pro? Ask These 7 Smart Questions First]

But clogged gutters can cause water to overflow where you don’t want it, potentially contributing to problems with your roof, siding, foundation, and basement. MAJOR problems that cost A LOT of money.

Winter can make an existing gutter problem worse. Before leaves are completely down, clean out the gutters and check that water is actually flowing toward the downspouts.

2. Check Your Downspouts

Cleaning the gutters isn’t enough. Make sure your downspouts are directing water away from your foundation. This one took me a few years to learn (and we bought extenders that do a nice job).

Look for:

Clogged downspouts
Loose connections
Cracks or holes
Extensions that have come loose
Water pooling near the foundation

Older homes often have interesting drainage situations, especially if additions, porches, or landscaping have been added over the years.

If water is consistently ending up next to your foundation, winter is not the time to ignore it.

3. Look at Your Roof

You don’t necessarily need to climb onto your roof. Actually, please don’t. It’s way too high – you’ll scare me.

From the ground, look for obvious problems such as:

Missing or damaged shingles
Sagging areas
Damaged flashing
Debris
Areas where water may be getting in

If you see something questionable, have it inspected by a professional. A small roof problem in October can become a much bigger problem once snow, ice, and freezing temperatures arrive.

4. Check Your Chimney

If your old house has a fireplace or wood stove, fall is a good time to have it inspected and cleaned as appropriate. And please use a professional – you don’t want to mess with missing a potential fire safety issue.

But you can look for obvious exterior damage on the chimney or flue, including cracked masonry or deteriorating mortar.

5. Take a Look at Your Foundation

Walk around the outside of your house and look for obvious cracks, gaps, or areas where water is collecting near the foundation.

You don’t need to become a structural engineer. You’re simply looking for something that has changed or looks different from what you’ve seen before.

And while you’re there, check that soil and landscaping are directing water away from the house rather than toward it.

6. Trim Problem Branches

Take a look at trees near your house.

Are there branches hanging over the roof?
Are any branches dead or damaged?
Could a heavy snow or ice storm bring them down onto your house, driveway, or power lines?

Fall is a good time to deal with questionable branches before winter weather turns them into a problem.

7. Check Your Old Windows for Drafts

Now we’re getting into the things that make preparing an old house for winter a little different.

If you own an old house, chances are good that at least one window has a personality of its own. Maybe it rattles. Maybe you can feel a breeze around the frame.

Walk around the house and pay attention to which windows feel particularly drafty.

You don’t necessarily need to replace an old window. Instead, look at the condition of the sash, glazing, weatherstripping, locks, and surrounding frame.

Sometimes a relatively small repair or weatherstripping improvement can make a noticeable difference.

Tip: Don’t assume that an old window is automatically a bad window. Historic wood windows can often be repaired and improved rather than replaced.

8. Check Your Storm Windows

If your old house has storm windows, now is the time to make sure they’re ready.

Check that they:

Fit properly
Are not damaged
Close securely
Have functioning hardware
Don’t have obvious gaps

Storm windows can play an important role in making older windows more comfortable during cold weather. And in my case, just making sure that the basement storm windows are completely closed so that cold air won’t freeze the water pipe right under it, requiring a plumber at 1am….

If you have removable storm windows, don’t wait until the first freezing weekend to discover that you can’t remember where you stored them.

9. Inspect Your Window Glazing

Take a look at the glazing around older wood windows.

Is it cracked?
Missing?
Loose?
Peeling?

Damaged glazing can allow water and air to get where they shouldn’t.

You don’t have to reglaze every window in October. Just identify problems that need attention and prioritize the ones that are damaged or exposed to the weather.

10. Check Weatherstripping Around Doors

Old doors are charming. And also allowing cold air into your living room.

Check the weatherstripping around exterior doors and replace damaged or missing sections. Pay particular attention to the bottom of the door. A door sweep can make a surprisingly noticeable difference in a drafty entry.

And don’t forget less-used exterior doors, like the basement door or hatch. The door you rarely use may also be the one that lets in the most cold air.

11. Find the Draftiest Areas of Your House

You don’t need fancy equipment to start.

On a cold or windy day, simply walk around your house and pay attention.

Which rooms feel colder?
Where can you feel air movement?
Which windows rattle?
Which exterior doors feel chilly?

Write down the problem areas now. That way, when you have time and money for improvements, you have an actual list instead of vaguely remembering that “the upstairs is always cold.”

12. Schedule Heating System Maintenance

Before you need your heating system to work around the clock, make sure it is ready. Schedule your annual professional maintenance appointment sooner than later.

Depending on your system, that might mean:

Scheduling annual maintenance
Replacing filters
Checking the thermostat
Inspecting the boiler or furnace
Checking fuel levels
Making sure heating vents are unobstructed

If something has been acting strangely, don’t wait until the coldest night of the year to investigate.

Old houses are charming. No heat at 2 a.m. in January is not.

13. Prepare Your Radiators

If your old house has cast-iron radiators, give them a little attention before heating season starts.

Make sure they’re not blocked by furniture, curtains, or other objects.
Give them a good cleaning and dusting.
Check for obvious leaks or damage.

And if you have a steam or hot-water system that has been making unusual noises or behaving differently, have it checked.

14. Check Your Thermostats

Walk around the house and make sure your thermostats are working properly.

If you have multiple heating zones, check each one.

If your thermostat batteries need replacing, do it now.

This is also a good time to think about whether certain rooms are consistently too hot or too cold. Uneven heating can sometimes point to a larger issue worth investigating.

15. Disconnect Garden Hoses

This is one of the easiest items on the list—and one of the easiest to forget.

Disconnect garden hoses before freezing temperatures arrive.

If your outdoor faucets have interior shutoffs, make sure they’re properly shut off and drained as appropriate for your plumbing system.

Why? Because water left in vulnerable pipes can freeze, expand, and potentially cause a very expensive plumbing problem. Ask me how I know – UGH…..

16. Protect Vulnerable Pipes

Walk through your basement, crawlspace, garage, or other unheated areas.

Look for exposed plumbing. Pay particular attention to pipes located near exterior walls or areas that can become very cold. Or an uninsulated basement. Add wrapping or insulation around these pipes.

The goal isn’t to wrap every pipe in your house. It’s to identify the vulnerable ones before the first hard freeze.

17. Know Where Your Main Water Shutoff Is

This is one of those things every homeowner should know.

Where is your main water shutoff?
And can you actually turn it off?

If a pipe bursts in the middle of winter, you don’t want to be standing in the basement searching Google for “where is my water shutoff?” (Been there, done that, of course while my husband is away on business).

Find it now. Make sure family members know where it is, too.

And while you’re at it, make sure you know where your electrical panel and major heating-system controls are located.

18. Check Your Attic

Attics deserve some attention before winter.

Look for:

Signs of moisture
Water stains
Damaged insulation
Gaps or obvious air leaks
Blocked ventilation
Evidence of pests

Older houses can have a complicated relationship with insulation and ventilation. But don’t simply stuff insulation into every available space without understanding how your attic is supposed to breathe.

19. Look for Moisture in the Attic and Basement

While we touched on moisture before, I can’t stress enough how important is it to regulate moisture in your old house. It can wreak havoc on the physical and environmental aspects of your home. Before winter, look for signs that moisture is already getting where it shouldn’t. Look for:

Damp areas (including insulation)
Water stains
Musty smells
Leaks
Condensation
Signs of previous water intrusion

Winter isn’t necessarily going to create these problems, but it can exacerbate an existing problem that can be costly.

20. Check Smoke and Carbon Monoxide Detectors

Before heating season gets underway, test your smoke and carbon monoxide detectors.

Replace batteries if needed.
Check the age of the units and replace them according to the manufacturer’s recommendations.

This is also a good time to make sure you have detectors in the appropriate locations throughout the house.

21. Make a Winter Emergency Supply Check

Winter has a funny way of exposing the things you forgot to prepare. Check that you have basics such as:

Flashlights
Batteries
Blankets
Emergency food and water
Ice melt
Snow shovel
Backup heat or warming supplies, as appropriate
Phone chargers/power banks

You don’t need to build a bunker.

You just want enough supplies to handle a winter storm without making an emergency trip to the store.

22. Do a Final Walk-Through and Make List

Once you’ve made it through everything above, take one final walk around your house. It will take about 15 minutes.

Start outside. Look at the roof, gutters, downspouts, foundation, doors, windows, and trees.
Then walk inside. Check the coldest rooms.
Look at the windows. Check the basement. Look at the attic.
Think about your heating system.

And ask yourself one simple question:

What would I regret discovering during the first major snowstorm?

That’s the thing to deal with now.

Because here’s the truth: You are not going to fix everything before winter.

And that’s okay. Maybe the upstairs windows need to be reglazed. Maybe the attic needs more insulation.

Write it down as a spring project and put it on your calendar for spring. That way, “I need to do something about that window” becomes an actual plan.

Five Old-House Winterization Mistakes to Avoid

Preparing an old house for winter isn’t just about making a list of things to do. Sometimes it’s also about knowing what not to do.

1. Don’t seal everything without thinking about moisture

Air sealing can improve comfort and energy efficiency, but old houses need to be approached thoughtfully.

If you’re dealing with a significant insulation or air-sealing project, understand how moisture and ventilation work in your particular house.

2. Don’t assume replacement windows are the answer

A drafty window doesn’t automatically mean you need a new window.

Repair, weatherstripping, storm windows, and other improvements may be worth investigating first—especially if you have historic wood windows.

3. Don’t block your radiators

Furniture, curtains, and other objects can interfere with heat circulation.

Give those old radiators some breathing room.

4. Don’t ignore small water problems

A small leak in October deserves attention.

Winter is not the season to find out how well your house handles repeated freezing and thawing.

5. Don’t wait until the first freeze to learn your shutoffs

Find the water shutoff. Know where the electrical panel is. Know how your heating system works.

You will be very happy you did if something goes wrong.

Wrapping Up

One of the things I love about old houses is that they don’t have to be perfect. They creak. They settle.

The goal of winter preparation isn’t to erase all of those quirks. It’s to make sure the important stuff is working. Remember the goals:

Keep water out
Keep heat in
Protect pipes and heating system
Find small problems before winter makes them bigger problems

Make your list, and then work your way down it.

Your old house has made it through plenty of winters. With a little preparation, it should be ready for the next one, too.
