Insulate exposed pipes (crawl spaces, attics, garages, exterior walls)
Seal gaps and cracks where cold air enters (around pipe penetrations, foundation, vents)
Keep cabinet doors open during cold weather to allow warm air to circulate around pipes
Disconnect and drain outdoor hoses and shut off exterior water supply valves
Insulate outdoor spigots and use hose bib covers
Fix leaks that can let water move or freeze in small areas
Maintain steady indoor thermostat settings (especially at night)
Let faucets drip slightly during extreme cold to relieve pressure and prevent freezing
Use heat tape or pipe heating cables on at-risk pipes (follow manufacturer instructions)
Install freeze protection valves or self-regulating heat systems for vulnerable lines
Ensure proper drainage so water doesn’t remain in low spots
Know shutoff locations and keep replacement parts on hand (valves, insulation, tape)
