An autumn checklist for getting the home ready for winter

Getting a home ready for winter is mostly a matter of finishing the right jobs before the first hard freeze, the first heating season or the first heavy snow. The sequence below starts outside, where water and wind do the most damage, moves to the heating system and insulation and ends with a few indoor checks. Most of the work is inexpensive and can be done by a homeowner, while a few items justify a professional visit.

Aim to finish the outdoor tasks while the weather is still mild and dry, and book heating service before the first cold week, when technicians are less busy. Each section can be completed in an afternoon, though a thorough autumn may take several weekends.

Outside: water, leaves and openings

Begin with the gutters. Clear leaves and debris once most have fallen, and confirm that each downspout carries water well away from the foundation. Water that freezes in a clogged gutter adds weight and can pull fasteners loose, and ice that backs up under shingles can lead to leaks inside. Check that the gutters are secure and that seams and end caps are not leaking.

Next, disconnect and drain garden hoses. If the outdoor spigots have indoor shutoff valves, close those valves and open the outdoor faucets so the water left in the pipe can drain. Water trapped in a spigot or hose can freeze and split the fitting. Fit spigot covers only after the water has been turned off and the faucet has drained.

Look at the weatherstripping and caulk around windows and doors, and replace any worn strips. Close each exterior door and check whether the threshold seals against the floor. Start with the largest gaps you can feel with the back of your hand, since those let in the most cold air. A simple test is to close a door on a thin strip of paper: if the paper slides out easily, the seal needs attention.

Trim branches that overhang the roof or rub against the house. Limbs can scrape shingles in the wind or fall under the weight of snow. Work from the ground where possible, and leave any tree work near power lines to the utility or a qualified arborist. Finally, look at the roof from the ground for missing shingles and repair them before snow arrives.

Heating system and fireplace

Replace the furnace filter and confirm that supply vents and return grilles are unobstructed. Set the thermostat to heat and raise the setting to make sure the system responds. Then schedule a professional service visit for the furnace or heat pump before the first cold snap. A technician checks burners, combustion, safety controls and airflow, which are not safe to adjust without training. For a heat pump, the visit should include the outdoor unit and its defrost controls.

If you have a fireplace or wood stove, have the chimney inspected and cleaned by a certified chimney sweep before the first fire. Creosote buildup and cracked flue liners are common causes of chimney fires, and they are hard to judge without the proper tools. Test the carbon monoxide alarms near sleeping areas and replace any that are past their printed date. Those checks matter most in the first cold week, when the heating system runs for the first time after months of rest.

Also check the areas around exterior equipment. Leaves, lawn clippings and shrub growth can block airflow at an outdoor heat pump, and a furnace or water heater vent must stay clear of snow and debris so that combustion gases can leave the house. Keep a shovel or a stiff brush near the vent area so it can be cleared before a storm rather than during one.

Inside: insulation, pipes and ventilation

Look at attic insulation for uneven depth or compressed areas, and make sure the attic access hatch is sealed and insulated. Air sealing around the hatch and around pipes and wires that pass through the ceiling often reduces drafts more than adding insulation does. Wrap exposed pipes in unheated spaces such as garages, crawl spaces and attics with foam pipe sleeves, paying particular attention to any pipe running along an exterior wall.

Set ceiling fans to turn clockwise at a low speed, which pulls air up and pushes warm air that has risen back down the walls. Test the bathroom and kitchen exhaust fans, and clear dust from their grilles. Indoor humidity is also worth watching. Public guidance commonly suggests keeping relative humidity between roughly 30 and 50 percent. Condensation that repeatedly forms on the inside of windows is a sign that moisture is building up, and running exhaust fans while cooking and showering helps.

Winter also changes how the house is used. Darker mornings and evenings call for working exterior lights and clear walkways, and a check of the steps and railings before the first icy week reduces the risk of falls.

Jobs worth paying a professional for

Some autumn work is worth hiring out, not because a homeowner cannot understand it but because the risk or the tools require training. These jobs include furnace or heat pump service, chimney cleaning and inspection, electrical panel or wiring work, roof repairs that involve climbing or replacing many shingles and tree removal near structures or utility lines. Ask for licensing and insurance details, request a written estimate and check references before agreeing to any work.

Prioritize the bookings. An active roof leak should come before a routine service visit, and a furnace that will not light should be treated as urgent. A simple plan with a dated list of appointments makes the difference between a calm winter and an emergency call on the coldest night of the year.
