Why Winterizing in Fall Matters

If you wait until the first freeze, it’s already too late for many tasks. Caulking won’t adhere in sub-zero temps, outdoor plumbing can crack, and heating systems will already be working overtime. Doing the work in fall means:

• Lower utility bills when heating costs spike
• Fewer emergency repairs in the dead of winter
• A safer, more comfortable home

Step 1: Seal Air Leaks

Why it matters: Drafts can account for 25–30% of energy loss in a home.

• Windows & Doors: Use caulk for cracks and weatherstripping for gaps.
• Attic & Basement: Check around pipes, ducts, and vents for gaps where heat escapes.

Step 2: Insulate Pipes

Why it matters: Frozen pipes are one of the most expensive winter emergencies.

• Wrap exposed pipes in basements, crawlspaces, and garages.
• Pay special attention to pipes near exterior walls.

Step 3: Service Your Heating System

Why it matters: A furnace that isn’t maintained will run inefficiently and may break down mid-season.

• Replace filters now (and monthly during winter).
• Test your thermostat and consider upgrading to a programmable model.
• Vacuum vents and radiators for better airflow.

Step 4: Reverse Ceiling Fans

Why it matters: Warm air rises. Reversing your ceiling fan pushes heat down into the room.

• Flip the switch on your fan so blades spin clockwise.
• Use on low speed for even distribution.

---

Step 5: Protect Outdoor Plumbing

Why it matters: Frozen outdoor spigots can burst pipes inside your walls.

• Drain and store hoses.
• Shut off exterior valves and install insulated faucet covers.

Step 6: Add Insulation Where It Counts

Why it matters: Attic insulation is one of the most cost-effective energy upgrades.

• Lay unfaced fiberglass batts perpendicular to existing insulation.
• Aim for 10–14 inches total in colder regions.

Step 7: Prep Your Fireplace or Chimney

Why it matters: Creosote buildup causes fires, and drafts from unused fireplaces waste heat.

• Have chimneys inspected and cleaned.
• Install a chimney balloon or cap in unused fireplaces.

Step 8: Upgrade Lighting for Longer Nights

Why it matters: Energy-efficient bulbs cut costs when lights run longer in winter.

• Swap to LED bulbs in common rooms.
• Use smart plugs or timers to control usage.

Step 9: Check Safety Devices

Why it matters: Winter increases risks of carbon monoxide and fire.

• Test smoke and CO detectors.
• Replace batteries and keep extinguishers accessible.
