Winterize Your Home Before the First Freeze: Complete Guide

The first hard freeze in Chicagoland typically arrives in late October or November. Here's how to prepare your home so you're comfortable, protected, and not calling for emergency repairs in January.

Windows & Doors — Your Biggest Heat Loss Points

• Check all windows and doors for drafts — hold a candle near edges on a windy day
• Replace worn weatherstripping on all exterior doors
• Apply window film to single-pane or older double-pane windows as a temporary insulation boost
• If you're still dealing with old, drafty windows, the best time to replace is NOW — before the first freeze. Our crews install through early winter. Schedule before winter →

Roof & Gutters

• Clean gutters completely — clogged gutters cause ice dams
• Check that downspouts are clear and directing water away from the foundation
• Inspect roof for damaged shingles that could leak during winter storms or ice events

Exterior

• Disconnect and drain garden hoses
• Shut off exterior faucets from the interior shutoff valve
• Seal gaps around exterior penetrations with caulk or foam
• Check that siding is intact with no gaps where wind-driven snow could enter

Heating System

• Replace furnace filter
• Schedule furnace inspection/tune-up if not done recently
• Test your thermostat and verify heat works before you need it
• Bleed radiators if you have hot water heat

Don't Wait for Emergency

Every winter we get calls from homeowners with burst pipes behind failed windows, roof leaks from ice dams, and drafts so bad they're wearing coats inside. A few hours of preparation now prevents expensive, stressful emergencies later. If your windows, roof, or siding need replacing, doing it before winter is always better than waiting.
