Key exterior tasks when you prepare your home for winter in Chicago

Roof, gutters and downspouts
Clean gutters and downspouts so melting snow can drain properly. Ice dam formation often starts when gutters are blocked and heat escapes through the roof. PRG Management+1 Inspect for missing shingles or damaged flashing and repair now to prevent leaks.

Windows, doors, insulation and sealing drafts
Seal gaps around windows and exterior doors with caulk or weather-stripping. Older homes often lose a lot of heat through these openings, and even small cracks add up. One guide recommends adding insulation, checking basement walls, and upgrading to storm windows or heavy curtains. Move-tastic! Chicago Movers

Outdoor plumbing, patios and yard maintenance

Important interior & systems maintenance when you prepare your home for winter in Chicago

HVAC, furnace, filters and chimney
Schedule a professional furnace and HVAC check-up, replace filters, and consider installing a programmable thermostat. Indoor safety is equally important—according to the Illinois winter weather guide more than 400 Americans die yearly from accidental CO poisoning during winter. Illinois

Pipes, basements and crawlspaces
Frozen pipes cause costly damage. Insulate exposed plumbing in basements and garages, keep indoor temperature consistent even when you are away, and let faucets drip slightly when temps fall below freezing. Homes and Gardens

Smoke and CO detectors and emergency readiness
Test or replace smoke and carbon monoxide detectors. Create or update your emergency kit: flashlights, backup batteries, blankets, water. The Illinois winter weather prepared-ness guide details how heating system failures, storms or power outages can impact homes. Illinois

Suburban-specific considerations for homes in the North Shore, Northwest and Western suburbs

In the suburbs you often have larger yards, detached garages, longer driveways and higher commuting exposure. These features add some extra tasks when you prepare your home for winter in Chicago’s suburbs:

• Clear long driveways and walkways early. Stock snow-shovels, de-ice products, and snow-blower fuel. Local reports note the region’s first winter storm may hit early with heavier lake-effect snow. NBC Chicago+1
• Ensure garage doors seal well and insulation is intact, since cold ingress can bring chill into your home.
• For commuter homes, check that entry-ways and mud-rooms are setup for gear (boots, jackets, umbrella) to avoid bringing in snow and moisture.
• Winter landscaping matters too: trim any overhanging limbs that could load snow, secure outdoor furniture, and protect irrigation/sprinkler systems from freezing.
