Prepping Your New Home for Fall: The Essential Checklist

Why it matters

Preparing your home for fall is the most important seasonal transition for a homeowner. For those who recently purchased a resale home, this period is critical because you are likely unfamiliar with how the previous owners maintained the exterior envelope.

Neglecting fall prep often leads to expensive "emergency" repairs in the dead of winter. For example, failing to clean gutters can lead to ice dams, which may cause thousands of dollars in roof and interior water damage. Similarly, an unserviced furnace is far more likely to fail on the coldest night of the year, resulting in high after-hours labor rates from HVAC technicians. Proper fall maintenance protects your equity and ensures your first winter in the home is comfortable rather than chaotic.

How often

This checklist should be performed once per year, typically between late September and late October. You want to complete these tasks after the leaves have mostly fallen but before the first hard freeze or snowstorm hits your region.

What you need

• Tools: Extendable ladder, screwdriver set, adjustable wrench, garden hose, leaf blower, and caulk gun.
• Supplies: Exterior-grade silicone caulk, weatherstripping, various HVAC filter sizes (check your unit), and smoke/carbon monoxide detector batteries.
• Safety Gear: Work gloves, safety glasses, and a sturdy pair of shoes with good grip for ladder work.

Step-by-step: The fall prep checklist

1. Service the heating system

Do not wait for the first frost to turn on your heat.

1. Change the filter: Replace your 1-inch or 4-inch pleated filter. A dirty filter restricts airflow, forcing the blower motor to work harder and consume more electricity.
2. Test the thermostat: Flip the system to "Heat" and raise the temperature 5 degrees above the current room temp. Listen for the system to engage and feel for warm air at the vents.
3. Clear the perimeter: Ensure no furniture, drapes, or boxes are blocking floor vents or baseboard heaters.

2. Seal the exterior envelope

Drafts can account for a significant portion of heat loss in older resale homes.

1. Inspect windows and doors: Feel for moving air around frames. If you see daylight through door gaps, replace the weatherstripping.
2. Caulk gaps: Use exterior silicone caulk to seal holes where cables, pipes, or vents exit the house. Be sure to check the "drip cap" above windows.
3. Check the attic: If you have safe access, ensure insulation hasn't been moved or compressed. Ensure soffit vents are not blocked by insulation, as airflow is necessary to prevent moisture buildup.

3. Clear the gutters and drainage

1. Remove debris: Clean leaves and sticks from gutters. If the gutters are clogged, water will overflow and pool at your foundation, which can lead to basement seepage during the spring thaw.
2. Flush downspouts: Run a hose into the downspouts to ensure water is flowing freely.
3. Redirect water: Ensure downspouts terminate at least 3 to 5 feet away from the house foundation. Use splash blocks or extensions if necessary.

4. Winterize outdoor plumbing

Frozen pipes can burst and cause catastrophic flooding.

1. Disconnect hoses: Take all garden hoses off the spigots. If you leave a hose attached, water trapped in the pipe cannot drain and will freeze, potentially bursting the pipe inside your wall.
2. Drain the line: If you have an indoor shut-off valve for your outdoor spigots, turn it off and then open the exterior faucet to drain the remaining water.
3. Insulate: Install foam "socks" or covers over exterior faucets in climates where temperatures drop below freezing.

5. Inspect the roof and chimney

1. Ground-level inspection: Use binoculars to look for missing, buckled, or cracked shingles.
2. Check flashing: Look for gaps around the chimney or vent pipes.
3. Chimney sweep: If the home has a wood-burning fireplace and you don't know when it was last cleaned, schedule a professional sweep to remove creosote buildup, which is a leading cause of house fires.

When to call a pro

While most fall prep is DIY-friendly, certain tasks require specialized tools or licensing:

• HVAC Tune-up: A professional technician can check for heat exchanger cracks (a carbon monoxide risk) and lubricate moving parts.
• Chimney Cleaning: If you plan to burn wood, a certified chimney sweep is necessary to ensure the flue is clear of obstructions and creosote.
• Complex Roof Repairs: If you find damaged shingles or soft spots, hire a roofer. Shingle repair on a steep pitch is dangerous for beginners.
• Tree Trimming: If large branches are overhanging your roof or power lines, hire an arborist to remove them before heavy snow or ice causes them to snap.

Safety

• Ladder Safety: Always have a spotter when climbing a ladder. Ensure the ladder is on level ground and extends at least three feet above the roofline if you are stepping onto the roof.
• Carbon Monoxide: Fall is peak season for CO poisoning. Test every detector in the house. If your home is more than 10 years old, replace the detectors entirely.
• Electrical: If using a leaf blower or power tools outside, ensure they are plugged into a GFCI-protected outlet.

Cost

• DIY Basic Maintenance: $50–$150 (Filters, caulk, weatherstripping, and batteries).
• Professional HVAC Service: $100–$250 per visit.
• Professional Gutter Cleaning: $150–$350 depending on home size and height.
• Chimney Inspection/Sweep: $150–$400.
• Window Caulking/Weatherstripping: $5–$10 per window/door.
