Exterior Winter Preparation Tasks

Making sure the exterior of your home is buttoned up and prepared for the stresses of winter can prevent costly storm damage repairs. From your gutters to your sprinkler system, here’s what to check off your list.

Roof and Gutters

• Inspect for missing, damaged, or loose shingles. Repair as needed to prevent leaks from snow or ice dams.

• Clean gutters and downspouts to ensure water can flow freely away from your home. Blocked gutters can lead to ice dams and costly interior leaks.

• Install gutter guards if you have ongoing issues with leaf buildup.

• Check and repair flashing around chimneys, vents, and skylights.

• Remove or secure old roof equipment, such as unused antennas, to avoid damage in strong winds or under heavy snow.

• Use a roof rake to clear heavy snow loads after storms, especially on low-pitch roofs.

Yard and Landscape

• Trim trees and remove dead branches near the home to prevent storm damage.

• Store outdoor furniture in a shed or garage, or cover it with weatherproof covers.

• Drain and store garden hoses, and shut off water to exterior spigots.

• Blow out irrigation/sprinkler systems with an air compressor or hire a pro for winterization.

• Drain gas from lawn mowers, pressure washers, and similar equipment or add fuel stabilizer.

• Store garden tools, bikes, and seasonal equipment.

Driveways and Walkways

• Repair cracks in driveways and sidewalks to prevent ice expansion and further damage.

• Stock up on snow removal tools and ice melt.

• Mark driveway edges with reflective stakes if you plan to use a snowplow.

Indoor Winter Preparation Tasks

Winter prep continues inside the house. Each room benefits from targeted organization, cleaning, and insulation that support home-wide energy efficiency and safety.

Living Room

• Move furniture away from heating vents for optimal airflow.

• Switch to heavier rugs and throws to help insulate.

• Store summer décor so it’s out of the way.

• Use thick curtains to help retain heat. 

Kitchen

• Clean and test the kitchen vent hood; replace filters.

• Shift any appliances blocking heat radiators or vents.

• Stock pantry with basic winter staples and emergency food.

Bedrooms

• Swap in flannel or thermal bedding and heavier comforters.

• Add area rugs on cold floors.

• Install weather stripping and use insulated curtains.

• Check for window drafts and address as noted above.

Bathrooms

• Clean and test exhaust fans to prevent mold/mildew.

• Insulate pipes under sinks if on exterior walls. If your plumbing is older or more susceptible, follow additional methods to prevent burst pipes during winter.

• Stock up on thick towels, and consider a small space heater (safe for bathrooms) for added morning comfort.

Laundry Room

• Clean out dryer vents for fire safety.

• Insulate exposed pipes and check for leaks.

Basement/Attic

• Store holiday decorations and winter gear in labeled bins.

• Ensure the furnace area is free from clutter and combustibles.

Garage/Mudroom

• Organize all winter gear (coats, boots, gloves) using shelves or bins.

• Store battery packs, snow removal salt, and shovels near the door.

Timeline-Based Winterization Schedule

Late Summer/Early Fall (September to October)

• Inspect and repair the roof, chimneys, and gutters

• Schedule HVAC and fireplace/chimney inspections and cleaning

• Stock up on supplies (weather stripping, caulk, filters, emergency kit items)

• Prepare and store outdoor tools and furniture

Mid Fall (October to November)

• Drain and winterize sprinkler system and hoses

• Seal windows, doors, and cracks 

• Install insulation film on windows

• Add attic, pipe, and garage insulation

• Change HVAC filters and test thermostat settings

• Clean out gutters after all leaves have fallen

Late Fall (November to December)

• Set up snow removal gear and supplies

• Store final yard and gardening tools

• Test smoke and carbon monoxide detectors; replace batteries

Ongoing Winter Maintenance

• Regularly clear snow and ice from walkways, driveways, and the roof

• Check for ice dam formation

• Keep heating and emergency systems maintained

• Monitor for interior drafts, leaks, or cold spots, and address them quickly

• Replace air/furnace filters monthly during heavy use

DIY vs. Hiring Professional Contractors

When it comes to winter prep, some jobs are worth tackling yourself, while others are better left to the pros. DIY can save money and give you control over materials and timing, especially for simple, low-risk tasks like sealing drafts with weather stripping, cleaning gutters before the freeze, or installing window insulation kits.

Bigger projects are a different story. Roof or chimney work, furnace or boiler maintenance, and major insulation upgrades carry higher risks and often require specialized knowledge. Climbing ladders in icy conditions or working with gas systems isn’t just difficult—it can be dangerous.

We recommend handling the straightforward prep jobs you can safely manage and hiring a professional for anything technical, hazardous, or physically demanding, like roof work or heavy snow and ice removal. That way, your home stays warm, efficient, and safe all winter long. If you choose to go the professional route, find qualified home inspectors in your area to get started.
