October is the month to wrap up fall home maintenance before the first hard freeze. The four jobs that matter most: clean your gutters, get your heating system ready, prep outdoor faucets for winter, and test your smoke and carbon monoxide alarms. Here's what to tackle this month.
1. Clean gutters after the leaves drop, not before
Timing matters here. Clean too early and the trees refill your gutters a week later. The sweet spot is usually late October into November, once most of the leaves near your house are down but before freezing rain and snow arrive.
Why it's worth doing: clogged gutters can send water over the edge and down against your foundation, or let it back up under the roof edge, where it can rot the fascia. In freezing climates, packed gutters also hold water that can freeze and add weight.
When you clean them, check a few other things while you're up there:
- Downspouts: Run a hose through each one to confirm water flows freely, and make sure the discharge points away from the house rather than pooling next to the foundation.
- Gutter hangers: Look for sagging sections or loose brackets that could pull away under the weight of ice.
- Shingle grit: A lot of granules from asphalt shingles in the gutters can be a sign of a wearing roof.
- The roofline: From the ground, scan for missing, curled, or damaged shingles and lifted flashing around chimneys and vents. Binoculars help, and they keep you off the roof.
Our roof maintenance checklist walks through what to look for in more detail.
A note on ladders: Gutter cleaning on a single-story home is a reasonable DIY job if you're comfortable on a ladder and have someone to steady it. On a two-story home, a steep lot, or anywhere near power lines, it's a job worth handing off.
If you'd rather stay off the ladder altogether, Puls handyman technicians offer gutter cleaning. You can book a service online in a few minutes and skip the cleanup.
2. Get your heating system ready before you need it
The first chilly night is a bad time to discover your furnace won't light. A few simple checks now help you catch problems before you rely on the heat every day.
Before you turn on the heat:
- Swap the air filter. Check it monthly during heating season and change it at least every three months. Start the season with a fresh one. Write the date on the frame so you know when it went in.
- Do a test run. Turn the heat on during a mild afternoon. A faint dusty smell for the first few minutes is common as dust burns off. A smell that lingers, a gas odor, or banging and squealing are reasons to shut it off and call a pro.
- Clear the vents. Make sure supply registers and return grilles aren't blocked by furniture, rugs, or curtains.
- Check around the equipment. Keep the area around the furnace clear of storage, and keep outdoor heat pump units free of leaves and debris.
- Set a schedule on your thermostat. According to the U.S. Department of Energy, turning the thermostat back 7 to 10°F for eight hours a day can save as much as 10% a year on heating and cooling. One caveat: with a heat pump, deep setbacks can make the system run less efficiently unless you have a thermostat designed for heat pumps.
Anything involving gas lines, burners, or the inside of the furnace isn't a DIY job. If you ever smell gas, leave the house and call your gas utility from outside.
3. Get your outdoor water ready to shut down
Outdoor faucets and the pipes behind them can crack when the water inside freezes, and the damage often goes unnoticed until spring, when you turn the hose back on and water sprays inside a wall. You don't need to shut everything off yet, but October is the time to get ready so the shutdown is a quick job when cold weather arrives.
Prep now:
- Find the shutoff valve for each outdoor faucet. It's usually inside, in the basement, crawl space, or utility area, a few feet from where the pipe exits the wall. Make sure it turns easily. A stuck or leaking valve is much easier to fix now than on a freezing night.
- Check outdoor faucets for drips. A leaky spigot holds water right where it's most likely to freeze.
- Pick up supplies. Foam faucet covers and pipe sleeves for exposed pipes in garages and crawl spaces are inexpensive and easy to install.
- Schedule sprinkler winterization early. Many in-ground systems are blown out with compressed air, which can damage components if the pressure is wrong. It's usually a job for an irrigation pro, and their calendars fill up fast.
When overnight temperatures start dipping toward freezing:
- Disconnect, drain, and store your hoses. Coil them in a garage or shed so they don't crack.
- Close the indoor shutoff valve for each outdoor faucet.
- Open the outdoor faucet and leave it open so any remaining water drains and has room to expand.
- Drain pool supply lines according to the manufacturer's or installer's directions.
If you have frost-free spigots, you may not have a separate indoor shutoff. They're designed to resist freezing, but a hose left attached can trap water inside and defeat the design, so the hose still needs to come off.
4. Have the chimney inspected before the first fire
If you plan to use a fireplace or wood stove this winter, book an inspection now. The National Fire Protection Association's standard for chimneys and fireplaces, NFPA 211, calls for chimneys, fireplaces, and vents to be inspected at least once a year, with cleaning and repairs done as needed. That applies to gas fireplaces too, and even to chimneys you rarely use, since animals, moisture, and weather take a toll whether you light a fire or not.
An inspector is looking for creosote buildup (a flammable residue from burning wood), cracks in the liner or masonry, and blockages like nests or debris. Look for a sweep certified by the Chimney Safety Institute of America (CSIA).
Before your first fire of the season, you can also:
- Open and close the damper to make sure it moves freely and seals.
- Check that the chimney cap is in place to keep out animals and rain.
- Clear anything flammable, like decor, kindling piles, or throw blankets, away from the hearth.
- Make sure you have a sturdy fireplace screen and a metal container with a lid for ashes.
5. Test smoke and carbon monoxide alarms
Heating season means furnaces, fireplaces, space heaters, and closed windows, which is exactly when working alarms matter most.
The U.S. Fire Administration recommends:
- Testing every smoke alarm monthly using the test button.
- Replacing 9-volt batteries at least once a year, including backup batteries in hardwired alarms.
- Replacing the entire alarm every 10 years from the manufacture date (printed on the back), not the date you installed it.
- Having alarms in every bedroom, outside each sleeping area, and on every level, including the basement.
If your home has gas appliances, a fireplace, or an attached garage, you also need carbon monoxide alarms on every level and near sleeping areas. CO alarms usually have a shorter lifespan than smoke alarms, so check the manufacturer's replacement date on each unit.
If an alarm is hard to reach, or you'd like to upgrade to interconnected or smart alarms that alert your phone, this is a quick job for a handyman or smart home technician.
6. Find and seal drafts around windows and doors
October weather is ideal for this one. It's cool enough to feel drafts but usually still warm enough for caulk to cure properly, since most products need above-freezing temperatures (check the label).
The payoff can be real. The EPA estimates that homeowners save an average of 15% on heating and cooling costs by air sealing and adding insulation in attics, floors over crawl spaces, and basements. Weatherstripping a few doors won't get you all of that, but it's a cheap, satisfying place to start.
How to find leaks: On a windy day, hold a lit incense stick or a strip of tissue near window frames, door edges, outlets on exterior walls, and attic hatches. If the smoke or tissue moves, air is getting through. You can also look for daylight around closed exterior doors.
Common fixes:
- Worn weatherstripping on doors and operable windows: peel off the old strip, clean the surface, and apply new foam, felt, or V-strip.
- Gaps under exterior doors: install or adjust a door sweep.
- Cracked caulk around window and door trim: cut out the old bead and run a new one with exterior-grade caulk.
- Attic hatch: add weatherstripping around the edge and a piece of rigid foam on top.
One safety note: after a larger sealing project, have a heating technician confirm that gas or oil appliances like your furnace and water heater are still venting properly.
7. Give your appliances a pre-holiday check
Fall is when many appliances start working harder. Laundry moves indoors, ovens get ready for holiday cooking, and water heaters face colder incoming water. A little attention now can head off a breakdown in the middle of a busy season.
Clean the dryer vent. This is the big one. U.S. Fire Administration data shows that home dryer fires happen more often in the fall and winter, peaking in January, and that failure to clean was the leading factor behind them. Clean the lint screen after every load, then pull the dryer out, disconnect the duct, and clear lint from the duct and the exterior vent hood. Warning signs of a clogged vent include clothes that take longer than usual to dry, a dryer that's hot to the touch, or a flap on the outside vent that doesn't open when the dryer runs.
Vacuum the refrigerator coils. Dusty condenser coils make the fridge work harder, and it's about to be packed with holiday groceries. Check your owner's manual for where the coils are and how often the manufacturer recommends cleaning them.
Flush the water heater. Sediment that settles at the bottom of a tank water heater can reduce efficiency and cause popping or rumbling noises. Many manufacturers recommend flushing the tank periodically. Follow the instructions for your model, and turn off the power or gas first.
If an appliance is already acting up, it's usually cheaper to deal with it before it fails completely. Puls appliance repair technicians can diagnose what's going on and get it fixed before the holiday rush.
8. Wrap up the yard and outdoor gear
These tasks are less urgent than protecting your pipes, but they're easier now than after the first snow.
- Deal with leaves. A thick mat of leaves left on the lawn all winter can smother grass. Mowing over a light layer to chop it up can work; heavier piles should be raked or bagged. Keep leaves away from window wells, drains, and the base of exterior walls.
- Trim branches near the house. Limbs hanging over the roof or brushing siding are a risk once ice and wind arrive. Small branches you can reach from the ground are fair game; anything large, high, or near a power line is a job for a tree service.
- Store the mower and summer tools. Follow your mower's manual for winter storage. That usually means either running it dry or adding fuel stabilizer. Clean off caked grass and store hand tools somewhere dry.
- Clean and cover outdoor furniture. Bring cushions inside, and cover or store furniture that isn't built for winter.
- Check the deck and walkways. Look for loose boards, popped nails, and cracked steps. Fixing a trip hazard now is easier than doing it in the dark on an icy evening.
- Test the garage door. Cold weather can make garage doors louder and slower, and it's the door many people use every day in winter. Make sure the auto-reverse safety feature works by placing an object in the door's path as it closes. If the door is noisy, jerky, or doesn't reverse, have it looked at. Every Puls garage door repair includes a 25-point inspection.
Home maintenance FAQs
What home maintenance should I do in the fall?
Focus on the tasks that protect your home from cold and wet weather: clean the gutters, get your heating system ready, prep outdoor water lines for winter, test smoke and carbon monoxide alarms, and seal drafts around windows and doors. Fall is also a good time to clean the dryer vent and wrap up the yard.
How often should I do home maintenance?
A mix of quick monthly checks and bigger seasonal tasks works for most homeowners. Monthly, test alarms and check your HVAC filter. Each season, tackle the jobs tied to the weather ahead. Our home maintenance calendar breaks it down month by month.
How often should I change my furnace filter?
Check it monthly during heating season and change it when it looks dirty, or at least every three months. Homes with pets or allergies may need more frequent changes.
What happens if I skip seasonal maintenance?
Small issues tend to grow quietly. A clogged gutter can lead to water damage, a dirty dryer vent becomes a fire risk, and a worn weatherstrip slowly raises your energy bills. Staying ahead of these is almost always cheaper than repairing the damage later.
Is it too late to do fall maintenance in November?
Not at all. Indoor tasks like testing alarms, changing filters, and cleaning the dryer vent can happen any time. Outdoor water shutoff is the one to prioritize if a freeze is in the forecast.
