How to Prep Your Home Before a Freeze

Freezing temperatures can cause serious damage to your home, from burst pipes to HVAC system failures. Taking proactive steps before cold weather arrives can prevent costly repairs and keep your family safe and comfortable.

Preventing Frozen Pipes

Identify Vulnerable Pipes

Locate pipes at risk:

• Pipes in unheated areas (attics, crawl spaces, garages, basements)
• Pipes along exterior walls
• Outdoor faucets and hose bibs
• Pipes in cabinets under sinks on exterior walls
• Pipes in unheated rooms or additions
• Irrigation system pipes

Inspection checklist:

• Walk through your home and identify all exposed pipes
• Check attic, basement, and crawl space
• Inspect garage and any unheated areas
• Look for pipes near exterior walls

• Don't forget pipes in basements if they're in unheated areas

Installation tips:

• Measure pipe diameter to get correct insulation size
• Cut insulation to fit snugly around pipes
• Seal joints with tape to prevent gaps
• Cover all exposed sections
• Replace damaged or missing insulation

Outdoor Faucets

Winterize exterior plumbing:

• Turn off water supply to outdoor faucets (usually a valve inside)
• Drain all water from faucets and hoses
• Disconnect and store garden hoses
• Install frost-free faucet covers
• Consider installing frost-free faucets if you don't have them
• Check that faucets aren't dripping (indicates they may not be fully closed)

Frost-free faucet covers:

• Install covers before first freeze
• Ensure covers fit snugly
• Check that covers are in good condition
• Replace damaged covers

HVAC System Preparation

Heating System Maintenance

Before freeze season:

• Monitor indoor temperature during extreme cold

Interior Preparation

Windows and Doors

Seal against cold air:

• Check weatherstripping for gaps or damage
• Replace worn weatherstripping
• Apply caulk around window and door frames where needed
• Use draft stoppers at the bottom of doors
• Close curtains and blinds at night to retain heat
• Consider window insulation film for older, drafty windows

Inspection:

• Feel for drafts around windows and doors
• Look for gaps in weatherstripping
• Check that doors seal properly when closed
• Inspect window frames for damage or rot

Insulation and Sealing

Keep warm air in:

• Check attic insulation levels (should be R-30 to R-60 depending on region)
• Seal air leaks around windows, doors, and electrical outlets
• Inspect and repair ductwork insulation
• Ensure attic access door is properly insulated
• Add insulation where needed (attic is usually the priority)

Air leak detection:

• Use incense or smoke pencil to find drafts
• Check around windows and doors
• Inspect electrical outlets and switches
• Look for gaps in attic and basement
• Seal with caulk or weatherstripping

Basement and Crawl Space

Protect below-grade areas:

• Insulate pipes in unheated basements or crawl spaces
• Ensure proper ventilation (prevents moisture issues)
• Check for signs of water intrusion
• Seal gaps that could allow cold air in
• Consider insulating basement walls if space is unheated

Emergency Preparedness

Know Your Systems

Critical information:

• Location of main water shutoff valve (most important!)
• Location of electrical panel and how to reset breakers
• Location of gas shutoff valve (if applicable)
• How to operate your heating system manually
