Winterizing a home means reducing heat loss, protecting water systems and equipment, and checking critical systems before severe cold arrives. Prioritizing the work prevents spending effort on small comfort fixes while larger risks such as exposed pipes or neglected heating remain.
Start with heating, alarms, and combustion safety
Complete the maintenance your heating system requires and replace filters when due. Test smoke and carbon-monoxide alarms, and if you use a fireplace or fuel-burning equipment, make sure vents and flues are in serviceable condition.
Protect vulnerable pipes and outdoor faucets
Disconnect hoses, follow the proper shutoff or draining procedure for your outdoor faucets, and insulate vulnerable pipe runs. Know where the main water shutoff is before an emergency occurs.
Seal accessible drafts
Check weatherstripping at doors, windows, and visible penetrations. Air sealing reduces drafts and heating load, but do not block vents, combustion-air openings, or ventilation paths designed to operate.
Prepare the exterior and plan for outages
Clean gutters when safe, secure lightweight outdoor items, and inspect damaged branches away from power lines. Keep flashlights, batteries, and a safe outage-heating plan; never run grills or generators inside a home or garage.
