13 Fall Home Maintenance Checklist Tasks Before October

Use this fall home maintenance checklist to handle 13 tasks before October and avoid winter issues.

1. Clean Gutters and Downspouts

Rent a 24-foot extension ladder from Home Depot for $35 and remove debris with a $12 plastic gutter scoop. Flush with a garden hose set to medium pressure.

⚡ Quick win: Check one downspout for clogs in 15 minutes using a leaf blower on low.

2. Replace Furnace Filter

Buy a 16x20x1 MERV 8 filter at Target for $8 and swap it in under five minutes. Set a phone reminder for every 90 days.

3. Inspect and Seal Windows

Apply DAP Alex Plus caulk ($4 tube) around frames on north and west sides. Use a $6 caulk gun from Ace Hardware.

4. Test Smoke and CO Detectors

Press the test button on each unit; replace 9V batteries ($1 each at Walmart) if older than one year.

⚡ Quick win: Label each detector with a Sharpie date in 10 minutes.

5. Check Attic Insulation

Pull back insulation near the hatch and verify at least R-38 depth using a tape measure. Add Owens Corning R-30 batts ($48 per bag) if gaps exceed 6 inches.

6. Service Garage Door Opener

Tighten chain tension with a 7/16 wrench and lubricate rollers with WD-40 Garage Door Lubricant ($6 can).

7. Clean Dryer Vent

Disconnect the vent hose and remove lint with a $22 dryer vent brush kit from Amazon. Reattach with a metal clamp.

⚡ Quick win: Vacuum the lint trap housing in 8 minutes.

8. Trim Trees Near Roof

Cut branches within 6 feet of shingles using Fiskars 8-foot pruners ($29 at Lowe’s). Bag clippings for yard waste pickup.

9. Reverse Ceiling Fan Direction

Flip the switch on each fan to clockwise so warm air circulates downward during fall and winter.

10. Inspect Exterior Paint and Siding

Look for peeling on south-facing walls and touch up with Sherwin-Williams Duration paint ($72 per gallon) matched to your existing color code.

⚡ Quick win: Tighten one loose shutter screw with a cordless drill.

11. Flush Hot Water Heater

Attach a garden hose to the drain valve and run water until it clears for 5 minutes. Wear gloves and safety glasses.

12. Stock Emergency Kit

Place a $28 flashlight, extra batteries, and 2 gallons of water in a plastic bin near the basement stairs.

13. Schedule Professional HVAC Tune-Up

Book a $99 fall service call through Angi or a local tech before September 15 to check refrigerant levels and belts.

Common Mistakes to Avoid

Skipping the attic inspection leaves ice dams likely; always measure insulation depth first. Using cheap foam tape on windows fails in under a month—choose paintable caulk instead. Ignoring the dryer vent causes 40% higher fire risk; clean it fully every fall.
