Fall Home Maintenance Checklist

Every fall, I do the same little walk-around: I listen for rattling downspouts, feel for drafts with the back of my hand, and try to spot the small stuff that turns into expensive stuff once the temperature drops. If you have ever dealt with a frozen hose bib (outdoor faucet), an ice dam, or a furnace that quits on the first cold night, you know why fall maintenance matters.

This checklist is built for real life. It is room-by-room, weekend-friendly, and focused on three goals: keep water from freezing where it should not, keep heat inside, and catch issues while they are still cheap.

Before you start: a quick tool and supply list

You do not need a garage full of fancy gear. This is the basic kit that covers most items below.

• Safety: work gloves, safety glasses, dust mask, sturdy ladder, headlamp
• Draft and insulation: exterior-grade caulk, spray foam (minimal-expanding), weatherstripping, foam outlet gaskets, door sweep
• Roof and gutters: gutter scoop, garden hose, bucket, gutter guards (optional)
• HVAC: furnace filters, shop vac, flashlight
• Plumbing: faucet covers, pipe insulation sleeves, heat tape (only where appropriate)
• Garage: silicone spray or garage door lube, concrete crack filler (as needed)

My thrifty tip: If you are on a tight budget, start with the cheapest energy wins: a new furnace filter, weatherstripping at doors, and sealing obvious gaps where pipes and wires enter the house.

Outdoor first (this is where winter damage starts)

1) Gutters and downspouts

• Clean gutters thoroughly and flush with a hose.
• Make sure downspouts discharge away from the foundation, generally 4 to 6 feet, or into a solid drain if you have one.
• Check for loose fasteners, sagging sections, and leaky seams.

Clogged gutters can make winter water problems worse: overflow, icicles, and backup where water has nowhere to go. Ice dams are usually driven by heat escaping into the attic, but good gutters still help keep roof runoff moving the way it should. I learned that the hard way on our old ranch when a “it can wait” gutter section turned into water staining in a bedroom ceiling.

Quick safety note: If you are not comfortable on a ladder, hire this one out. A clean gutter is not worth a bad fall.

2) Roof and flashing check

• From the ground or a ladder safely set up, look for missing shingles, lifted corners, and damaged vent boots.
• Inspect flashing around chimneys, skylights, and wall intersections for gaps.
• Trim branches that hang over the roof to reduce debris and storm damage.

3) Yard grading and drainage

• Confirm soil slopes away from the foundation.
• Clear leaves from window wells, drains, and low spots where water collects.
• Store items that can crack in freeze-thaw cycles (pavers, planters). Clean and store tools so they do not rust.

Note: Downspout extensions and splash blocks help, but they are not a substitute for proper grading and drainage.

4) Exterior caulk and siding touchups

• Check caulk at windows, doors, and siding joints. Re-caulk cracks and gaps.
• Spot prime and paint peeling wood trim before winter moisture gets behind it.

Caulk rule: If the gap is moving a lot or larger than about 1/4 inch, you may need backer rod or a different repair. Do not just dump caulk into a canyon and hope for the best.

Entryways and draft control

5) Front and back doors

• Replace worn weatherstripping and add a door sweep if you see daylight.
• Tighten hinge screws and strike plates. A snug door seals better.
• Check the threshold adjustment (many are adjustable with a screwdriver).

My favorite quick test is the dollar bill test. Close the door on a bill and tug. If it slips out easily, you likely have a sealing problem.

6) Windows (especially older double-hungs)

• Lock windows to pull sashes tight against weather seals.
• Re-caulk exterior window trim where needed.
• Use interior rope caulk or seasonal film on problem windows if the budget is tight.

Basement and crawl space (pipe-freeze headquarters)

7) Seal rim joists and penetrations

• Air seal gaps where pipes, wires, and ducts enter the house.
• Check the rim joist area for obvious drafts and consider foam board plus spray foam to seal the edges.

This is one of the best bang-for-your-buck comfort upgrades. It is also where I see beginners overdo it with expanding foam. Use minimal-expanding foam where it is needed for control, and do not block intentional vents or combustion air openings for fuel-burning appliances. If you have a furnace or water heater that pulls air from the room, keep that area safe and code-compliant.

8) Prevent frozen pipes indoors

• Insulate exposed pipes in unheated areas with foam sleeves.
• Protect vulnerable runs near exterior walls.
• In very cold climates, consider heat tape on specific pipes, installed per manufacturer instructions and plugged into a GFCI outlet. Do not overlap it, and replace old or damaged heat tape.

Important: Insulation helps, but it does not create heat. If a space will be below freezing for long stretches, you may also need to address air leaks and the heat source.

Do not forget: Indoor pipe protection works best when you also winterize outdoor faucets. See Step 21.

9) Sump pump and drainage check (if you have one)

• Test the pump by pouring water into the pit until it activates.
• Verify the discharge line is not clogged and drains away from the house.
• If you use a flexible discharge hose outside, remove it before freezing weather so it cannot freeze solid and burn out the pump.
• Consider a battery backup if power outages are common in winter storms.

Kitchen and bathrooms (water and ventilation)

10) Under-sink checks

• Look for slow leaks at shutoff valves, traps, and supply lines.
• Clean out the cabinet so pipes are not pressed against an exterior wall with no airflow.
• If the sink is on an exterior wall, keep the cabinet crack-open during deep freezes to let warm air circulate.

11) Exhaust fans and humidity control

• Clean bathroom fan grilles and verify the fan actually moves air.
• Make sure the fan vents outdoors, not into an attic.
• Use the fan during showers and for 15 to 20 minutes after to prevent condensation and mold.

Living areas and bedrooms (comfort and efficiency)

12) Swap furnace filters and clear returns

• Install a fresh filter and write the date on the frame.
• Vacuum around returns and make sure rugs or furniture are not blocking airflow.

13) Outlet and switch drafts on exterior walls

• Install foam gaskets behind cover plates on exterior walls.
• Use child-safety plugs in unused outlets if you feel a noticeable draft.

It feels almost silly until you do it, then you notice the room is less “chilly around the edges.” Cheap fix, real payoff.

14) Fireplace and chimney basics

• If you use a wood-burning fireplace, schedule a chimney inspection and cleaning as needed.
• Check that the damper opens and closes smoothly.
• For gas fireplaces, follow the manufacturer maintenance schedule and consider a professional check if it has been a while.

15) Space heater basics (if you use them)

• Keep a 3-foot clearance around space heaters.
• Plug directly into the wall, not an extension cord or power strip.
• Turn them off when sleeping or leaving the room.

Mechanical room (where winter comfort is made)

16) Furnace or boiler check

• Listen for unusual noises and check for short cycling.
• Vacuum dust around the unit and keep the area clear for safe airflow.
• If your system is older or has been acting up, book a professional service before the first cold snap.
• If you have a whole-home humidifier, check and replace the pad or panel as recommended.

17) Water heater check

• Look for corrosion, drips, or a damp pan.
• Test the temperature and pressure relief valve if you know the safe procedure and discharge location.
• Consider insulating hot water pipes in unheated areas.

Safety note: If you smell gas, see soot around a gas appliance, or your carbon monoxide alarms chirp, stop and call a pro immediately.

18) Carbon monoxide and smoke alarms

• Test every alarm.
• Replace batteries if needed.
• Verify you have a CO alarm on each level and near sleeping areas.

Laundry and fire safety

19) Dryer vent clean-out

• Clean the lint screen every load (yes, every load).
• Vacuum lint around the dryer and behind it.
• Inspect and clean the dryer vent duct and the exterior vent hood. Make sure the flap opens freely.
• If your vent is long, slow to dry, or you see lint outside, consider a pro cleaning. This is one of those boring tasks that can prevent a very un-boring fire.

Garage and outbuildings

20) Garage door seal and tune-up

• Replace the bottom seal if it is cracked or flattened.
• Lubricate rollers, hinges, and springs with a garage door lubricant.
• Check the auto-reverse safety feature on the opener.

21) Store chemicals and tools

• Keep paint and liquids that cannot freeze in a conditioned space.
• Stabilize fuel for gas equipment or run it dry before storage.
• Sharpen and oil hand tools so they are ready for spring.

Plumbing winterization (outside water is the big risk)

22) Outdoor faucets (hose bibs)

• Disconnect and drain all garden hoses.
• Shut off interior valves feeding outdoor spigots if you have them, then drain the line.
• Add insulated faucet covers for extra protection.

If you only do one fall task, do this one. A split pipe inside a wall is a fast track to a big repair.

Related: If you have plumbing that froze or got scary-close last winter, go back and do Step 8 too. Indoor protection plus outdoor shutdown is a strong combo.

23) Sprinklers and exterior plumbing

• Blow out irrigation lines if required for your climate and system type.
• Drain and store removable backflow preventers if applicable.

24) Find and test the main water shutoff

• Locate the main shutoff valve and make sure it turns.
• If it is stuck or corroded, get it addressed before winter. In a real leak, you do not want to be learning this on the fly.

Energy and insulation

25) Attic check (air seal, then insulate)

• Look for obvious air leaks around attic hatches, plumbing stacks, and recessed lights.
• Ensure bath fans vent outside.
• Confirm insulation is not blocking soffit vents.
• Look for signs of roof leaks (stains, damp insulation) and address them before snow season.
• Weatherstrip and insulate the attic access hatch if it is leaky.

Warm air leaking into the attic can contribute to ice dams. If you are choosing where to start, air sealing is often the best first move. After that, make sure your attic insulation level is where it should be for your region.

26) Thermostat basics

• Set a realistic schedule you will actually live with.
• Use modest setbacks you can tolerate. Heat pumps often do better with smaller setbacks than a typical furnace.

27) Outdoor heat pump or AC unit (if you have one)

• Clear leaves and debris from around the unit and keep airflow open.
• Make sure it is sitting level and not buried under mulch.
• If it is a heat pump you use for heating, do not cover it tightly. It needs to breathe.
