4 tasks
Clear all gutters and downspouts of leaves and debris
Clogged gutters cause overflow, fascia saturation, and ice dam formation. Check that downspouts flow freely by running a hose through them. Extend downspout discharge at least 6 feet from the foundation.
Critical
Inspect roof shingles and flashing for winter vulnerabilities
From the ground with binoculars: look for lifted shingles, cracked sealant, exposed nails, and loose or separated flashing at chimneys, skylights, and wall transitions. Anything compromised now becomes a major leak during the first winter storm.

Critical
Check for early ice dam risk indicators in the attic
Fall is the time to identify and fix attic heat-loss problems before snow arrives. Check for unsealed penetrations (recessed lights, bath fan chases, plumbing stacks) and confirm insulation isn't blocking soffit vents. Addressing these now prevents ice dams all winter.

Critical
Evaluate attic ventilation pathways
Confirm soffit vents are open and unobstructed by insulation, debris, or bird nests. Proper soffit-to-ridge airflow keeps the roof deck cold and uniform, which is the foundation of ice dam prevention. Compressed or missing baffles need to be corrected now.
Important
Timing matters
Roof and gutter tasks have a hard deadline — complete them before the first freezing temperatures, not just before the first snow. A single overnight freeze can turn a marginal gutter situation into a full ice dam.
5 tasks
Inspect exterior grading around the foundation
Soil must slope away from the home — at least 6 inches of drop over 10 feet — to prevent winter pooling and freeze-thaw foundation stress. Low spots near the foundation fill with water, freeze, and expand against the foundation wall. Add soil and regrade now while the ground is workable.
Critical
Extend downspout discharge 6–10 feet from the house
Short downspouts discharge at the foundation — the worst possible location during freeze cycles. Add extensions, corrugated pipe, or buried drains to move water at least 6 feet away. This single task prevents a significant proportion of basement seepage and foundation heave issues.
Important
Seal exterior gaps at windows, doors, and siding penetrations
Apply fresh caulk or weatherstripping around window frames, door frames, and any penetrations through siding — gas lines, electrical conduits, hose bib covers. Failed sealant allows winter wind infiltration and water entry. Replace cracked or missing caulk before freezing temperatures make adhesion difficult.
Important
Shut off and drain outdoor hose bibs
This is one of the most skipped tasks and one of the most consequential. Locate the interior shutoff valve for each outdoor spigot, close it, then open the outdoor spigot to drain remaining water from the line. An unprotected hose bib that freezes bursts the supply pipe inside the wall — typically discovered only after significant water damage.
Critical
Examine crawlspace vent condition
In cold climates (sustained temperatures below 20°F): close crawlspace vents for winter to prevent pipes from freezing. In milder climates: leave vents open year-round to prevent moisture buildup. Check vent covers for damage, bird nests, or insect intrusion. Confirm vapor barrier is intact on the crawlspace floor.
Routine
5 tasks
Replace the HVAC filter before heating season begins
A dirty filter restricts airflow, causes short cycling, and accelerates heat exchanger failure — the most expensive furnace component. Install a fresh filter rated for your system before the first heat call of the season. If your filter has been in more than 90 days, replace it regardless of apparent condition.

Critical
Test the furnace or heat pump in heating mode
Set the thermostat 5° above current room temperature and confirm: heat output at all registers within 5 minutes, smooth startup without hesitation, no burning smells beyond the first few minutes of operation, and no short cycling. A furnace that fails this test in October is far easier to repair than one that fails during a January cold snap.

Critical
Clear the area around the furnace
Remove stored items, boxes, and flammable materials from within 3 feet of the furnace and return air intake. Blocked airflow causes overheating and safety lockouts. This is also a fire safety issue — furnaces ignite nearby materials more often than most homeowners realize.
Safety
Inspect and test thermostat operation
Replace batteries in battery-powered thermostats. Test heating mode programming if you have a programmable or smart thermostat. Confirm temperature accuracy by comparing to a separate thermometer. A thermostat that reads 2° off is responsible for significant energy waste over a full heating season.
Routine
Inspect accessible ductwork for loose joints and damage
In the basement, crawlspace, or attic, look for disconnected duct sections, missing insulation on ducts running through unconditioned spaces, or visibly crushed flex duct. Leaking ducts in unconditioned spaces can waste 20–30% of heating output. Reconnect loose joints with metal tape (not standard duct tape, which degrades).

From the field
"The two calls I get most in November and December are frozen hose bibs and furnaces that won't start. Both are completely preventable with a single afternoon in October. The hose bib takes five minutes per spigot. The furnace test takes ten minutes. But once it's January and you're without heat during a cold snap — or dealing with water damage from a burst pipe inside a wall — you're looking at emergency service rates, days without heat or water, and repairs that could have cost almost nothing. Fall maintenance pays for itself by a factor of ten."

3 tasks
Insulate exposed pipes in vulnerable locations
Pipes in crawlspaces, garages, attics, and exterior walls are all at freeze risk. Install foam pipe insulation (pipe wrap) on any supply line that runs through an unheated space. Focus first on pipes on the north and exterior-facing walls, and any pipe within 2 feet of an exterior surface.

Critical
Test sump pump function before heavy fall rains
Pour a 5-gallon bucket of water into the sump pit to confirm the float triggers the pump and water is ejected fully. Check that the discharge line runs far enough from the house and isn't blocked. A failed sump pump in a saturated fall is the most common cause of basement flooding — and it always fails during the rain event, not before it.
Important
Inspect water heater for efficiency and sediment issues
Sediment buildup reduces recovery speed during peak winter demand (long showers, holiday guests). Listen for rumbling or popping sounds during heating cycles — a sign of significant sediment. Flush the tank if you haven't in more than a year. Also check the temperature setting (120°F recommended) and inspect the anode rod if the unit is over 5 years old.

4 tasks
Test all GFCI, AFCI, and standard circuit breakers
Press the TEST button on every GFCI outlet and confirm the RESET button pops. Check that AFCI breakers in bedrooms respond to their test buttons. Verify that no standard breakers are in a tripped position. A breaker that trips repeatedly needs professional attention before you add holiday lighting loads.
GFCI guide →
Safety
Check outdoor lighting and security fixtures
Shorter days mean outdoor lighting becomes essential for safety and security. Replace bulbs in motion-sensor lights, check fixture covers for moisture intrusion, and confirm photocell timers are set correctly for the earlier dusk. Outdoor GFCI outlets should be tested for proper operation.
Routine
Test every smoke detector and carbon monoxide detector
Press the test button on each unit. Replace batteries in battery-powered units regardless of apparent charge — a battery that tests okay in October may fail during a cold January night. CO detectors are especially critical in heating season: furnaces, fireplaces, and attached garages all present CO risks that escalate in cold weather with reduced ventilation.
Safety
Inspect and test-run the generator (if applicable)
Check oil level, run the generator under load for 20–30 minutes, and confirm the transfer switch or interlock operates correctly. Test before winter because generator service and repair shops are overwhelmed after the first major outage. Keep a minimum of 5 gallons of fresh fuel stabilized and ready.
Important
4 tasks
Inspect doors and windows for drafts and air leaks
On a cold, windy day: hold a lit incense stick or smoke pencil near the perimeter of each door and window frame. Smoke that moves toward the frame confirms air infiltration. Check weatherstripping for compression and replace if it's flat or cracked. Door sweeps should make contact with the threshold across the full width.
Important
Review attic and wall insulation levels
In the attic: verify insulation covers the entire ceiling plane without gaps, and that it's at the depth recommended for your climate zone (typically R-49 to R-60 in cold climates). Check for areas where insulation has settled, been compressed, or was never installed — particularly around the perimeter and at the attic hatch. Inadequate insulation is the primary driver of ice dams and high heating bills.
Important
Check for moisture and mold in basements and crawlspaces
Inspect for water staining, white efflorescence on walls, musty odors, or visible mold. Fall is the last opportunity to address moisture issues before winter traps humidity in enclosed spaces. Install a dehumidifier if humidity in the basement exceeds 55% routinely in fall. Address any active seepage paths before they freeze and expand.
Important
Prepare fireplace or wood stove for the heating season
Have the chimney cleaned and inspected by a certified chimney sweep before first use of the season — creosote buildup is a fire hazard and the inspection catches deteriorated flue liners. Check the damper for full operation and proper sealing when closed. Stock a full cord of seasoned firewood before the first cold snap if you rely on wood heat.
Safety
The goal of fall maintenance
- Protect the roof and gutters before ice dams can form — addressing this in fall costs a fraction of winter repairs
- Winterize outdoor plumbing before the first freeze — a $5 shutoff valve protects against thousands in water damage
- Test the furnace in October — emergency service in January costs 3–5x a scheduled fall visit
- Seal the building envelope — every gap you seal now saves energy all winter and prevents moisture intrusion
- Test safety devices — smoke and CO detectors, GFCI breakers, and generator function all matter more in winter
