Which pipes are most likely to freeze, and can PEX pipes freeze too?

Pipes that run through unheated or drafty areas—like garages, crawl spaces, attics, and exterior walls—are the first to freeze when temperatures drop. Copper and PVC pipes are the most vulnerable because they’re rigid and can’t expand when ice forms inside. PEX piping is a bit more flexible, but it’s not freeze-proof; fittings and joints can still crack under pressure if the line freezes solid. To reduce your risk, make sure these pipes are insulated, seal any cold-air leaks, and maintain steady indoor heat. Bulldog Rooter’s licensed plumbers can inspect your system, insulate exposed lines, and protect your plumbing before the next cold snap hits. Call now for same-day service and 24/7 emergency support.
