How can I fix a frozen pipe safely without causing damage?

You can safely fix a frozen pipe by shutting off water to the line, warming the pipe slowly, and watching for leaks as it thaws. Freezing most often happens where cold air hits uninsulated pipe or a drafty sill, crawlspace, or exterior wall. Open flames can crack pipes; use only gentle, even heat and keep the faucet slightly open so meltwater can move. A useful pro move is to warm from the open tap back toward the cold spot so steam doesn’t get trapped. Technicians from Ultimate Heating & Air, Inc are available across the Boise–Meridian area if you need hands-on help, and 24/7 emergency service is offered.

• Open the nearest faucet to relieve pressure; leave it running.
• Use a hair dryer, heat tape, or a warm towel on the pipe; move heat slowly toward the cold section.
• If you see a bulge, dripping, or hear water with valves closed, shut off the main and call a plumber.

After thawing, insulate the pipe and seal nearby drafts to prevent another freeze.
