Fall Home Prep Checklist: 15 Tasks Before the Weather Turns

Fall is the window. The weather is still mild enough to work outside, but cold is coming. Every item on this list is something I have either dealt with myself or paid someone way more to fix because I waited too long. Do these on a couple of weekends in October (Northern Hemisphere) or April (Southern Hemisphere) and you will avoid the emergency calls that cost five times as much in January.

Exterior

1. Clean the Gutters

Clogged gutters cause ice dams in winter, which push water under your shingles and into your ceiling. I clean mine twice a year — once after the leaves fall, and once in spring. If you have a lot of trees near the house, consider gutter guards.

2. Inspect the Roof

You do not need to climb on the roof. Use binoculars from the ground or a drone if you have one. Look for missing, cracked, or curling shingles; rusted flashing; and any signs of animal damage.

3. Seal Gaps Around Windows and Doors

A 1/8-inch gap around a door lets in as much cold air as a 6-inch hole in the wall. Walk around the house on a windy day and feel for drafts.

4. Drain and Store Outdoor Hoses and Faucets

Leaving a hose connected through winter can trap water in the pipe, which freezes and splits the faucet from the inside. This is one of the most common — and most preventable — causes of spring flooding.

5. Check Exterior Drainage

Water pooling against your foundation in winter is a recipe for basement leaks and foundation cracks.

Heating System

6. Service Your Furnace or Heat Pump

This is the single most important item on the list. A furnace that has not been serviced can develop cracked heat exchangers (carbon monoxide risk), clogged burners, and failing blower motors — all of which are cheaper to prevent than to fix in an emergency at 2 AM in January.

7. Test Carbon Monoxide and Smoke Detectors

Heating season is when most CO incidents happen. Test every detector in the house.

8. Check Vents and Registers

Blocked or closed vents make your heating system work harder and can cause uneven heating or frozen pipes in unused rooms.

Plumbing

9. Insulate Exposed Pipes

Any pipe in an unheated space — crawlspace, attic, garage, exterior wall — is at risk of freezing. Foam pipe insulation sleeves cost a few dollars and take minutes to install.

10. Know Your Main Water Shutoff

If a pipe bursts, you need to stop the water fast. Know where the main shutoff valve is and make sure it turns. Tag it so anyone in the house can find it.

Interior

11. Reverse Ceiling Fans

Most ceiling fans have a switch on the motor housing that reverses the blade direction. In winter, you want clockwise rotation (looking up at the fan), which pushes warm air down from the ceiling without creating a draft.

12. Check Window Insulation

Single-pane windows and older double-pane windows with failed seals are a major source of heat loss. You do not need to replace them right away — window insulation film is a cheap temporary fix.

13. Clean the Dryer Vent

A clogged dryer vent is a fire hazard and makes your dryer run longer, using more energy. Lint buildup causes an estimated 2,900 dryer fires per year in the US alone (USFA data).

Safety and Preparedness

14. Restock Your Emergency Kit

Power outages and storms are more likely in winter. Check your kit before you need it.

15. Test Your Sump Pump

If you have a sump pump, test it before the ground freezes and spring thaw arrives. A failed pump in a wet season can flood your basement in hours.
