Fall Home Maintenance Checklist

Exterior

1. Clean and repair gutters — Wait until most leaves are down, then clear every gutter and flush the downspouts with a hose. Clogged gutters are the number-one cause of ice dams and foundation water damage. If sections are sagging, pulling away, or rusted through, size a replacement with our gutter calculator and see typical pricing in our gutter cost guide.
2. Inspect the roof — Walk the perimeter with binoculars and look for lifted, cracked, or missing shingles, damaged flashing around chimneys and vents, and moss buildup. Small repairs now beat mid-winter leaks. Estimate repair or replacement materials with the roofing calculator, and check how many years your roof likely has left in our roof lifespan guide.
3. Sealcoat the driveway while it's still 50°F+ — Sealer needs pavement and air temperatures of at least 50°F for 24–48 hours to cure, so early fall is your last window. Fill cracks first — water that gets in and freezes turns hairline cracks into potholes by spring. Figure out how many buckets you need with the sealcoat calculator and follow our step-by-step sealcoating guide.
4. Touch up exterior paint — Scrape and spot-prime any peeling or bare wood before winter moisture gets underneath and spreads the damage. Full repaint on the calendar for next year? Get a gallon count from the exterior paint calculator.
5. Caulk and weatherstrip — Recaulk gaps around window and door trim, siding joints, and where pipes or wires enter the house, and replace flattened weatherstripping on exterior doors. Air sealing is the cheapest heating-bill fix there is — a $6 tube of caulk routinely pays for itself in a single season.

Systems

6. Schedule a furnace tune-up — Book it in September or October, before HVAC companies hit their winter emergency backlog. A tune-up ($80–$200) catches cracked heat exchangers, weak igniters, and dirty burners before they become no-heat calls. If your furnace is 15+ years old, start budgeting with our HVAC cost guide so a failure doesn't force a rushed decision.
7. Test the heat before the first cold night — Run the furnace for 15 minutes on a mild day. A dusty burning smell for a few minutes is normal; anything that smells electrical, short-cycles, or won't reach the set temperature is not. Finding out in October beats finding out at 2 a.m. in December.
8. Clean the chimney and dryer vent — Have wood-burning chimneys swept before the first fire (creosote is the leading cause of chimney fires), and pull the dryer vent duct off the wall to clear lint from the full run. Both are cheap tasks that prevent house fires.
9. Winterize hose bibs and irrigation — Disconnect and drain garden hoses, shut the interior supply valves to outdoor faucets, and open the exterior spigots to drain. Blow out irrigation lines with compressed air before the first hard freeze — a cracked backflow preventer or burst line is a spring repair you don't need.
10. Test smoke and CO detectors — Heating season is carbon-monoxide season. Press the test button on every unit, replace batteries, and replace any detector over 10 years old (7 for CO). Put one CO detector on every sleeping floor.

Interior

11. Check attic insulation depth — Stick a tape measure through the hatch: if you can see the tops of the joists, you're under-insulated for heating season. Most homes need R-38 to R-60 in the attic depending on climate. Run your numbers through the attic insulation calculator to see how much to add and what it costs — it's the highest-ROI energy upgrade in most houses.
12. Reverse ceiling fans — Flip the small switch on the fan housing so blades spin clockwise on low. That pushes warm air pooled at the ceiling back down the walls into the room — worth a few percent on heating bills, and it takes 30 seconds per fan.

Yard

13. Feed the lawn — For cool-season grasses (fescue, bluegrass, rye), the fall feeding is the most important application of the entire year: it builds root reserves that drive spring green-up. Apply in September and again around Halloween. Get exact bag quantities for your square footage with the fertilizer calculator.
14. Overseed thin areas — Early fall soil is warm, air is cool, and weed pressure is low — the best seeding conditions of the year. Rake bare spots, spread seed, and keep it damp for two weeks. The lawn calculator tells you how many pounds of seed your yard needs.
15. Mulch beds for winter — Top up beds to 2–3 inches after the ground starts to cool. Mulch insulates roots against freeze-thaw cycles that heave perennials out of the ground. The mulch calculator converts your bed sizes into bags or cubic yards.
16. Drain and store outdoor equipment — Run mowers and trimmers dry or add fuel stabilizer, drain pressure washers and hoses completely, and store patio furniture and cushions. Gas left in a carburetor over winter is the top reason mowers won't start in April.
