Frozen pipes are most common where water lines pass through unheated crawlspaces, exterior walls, garages, basements near air leaks, and poorly insulated additions. Prevention starts by finding the vulnerable location—not simply turning the thermostat higher after a freeze begins.
This guide is based on Greg’s field experience diagnosing and repairing plumbing, steam, and hydronic systems in Scranton-area homes. Site conditions and equipment instructions control the final recommendation.
Control cold air first
A small opening can direct freezing air onto a pipe even when the surrounding room feels tolerable. Seal penetrations and drafts where appropriate, insulate the building cavity correctly, and protect piping from exterior airflow. Do not block required combustion-air openings.
Keep heat and water moving safely
Maintain indoor heat, open cabinet doors when plumbing is trapped against a cold exterior wall, and consider a controlled drip only as a temporary measure for a known vulnerable line. Disconnect outdoor hoses and shut down seasonal piping when the system is designed for it.
What to do if a pipe freezes
Shut off the water if the pipe is split or leaking. Avoid open flames and uncontrolled high heat. A frozen section can rupture before it thaws, and the damage may not become visible until water begins moving again.

Frequently asked questions
At what temperature do pipes freeze?
Risk rises during prolonged freezing weather, but insulation, wind exposure, pipe location, and indoor temperature matter as much as the outdoor reading.
Should I use heat tape?
Only listed equipment installed according to its instructions and suitable for the pipe and location should be used. Damaged or improvised heat tape can create a fire hazard.
