How freeze-thaw causes leaks
When water in a pipe freezes, it expands with enough force to rupture the line. The split may not leak while frozen; the water escapes once the line thaws and pressure returns. Exposed runs in crawlspaces, exterior walls, and unheated spaces are the usual victims.
Communities like Kelowna, Kamloops, Prince George, Fort St. John and Whistler see this every winter, and seasonally-vacant properties — cabins, recreation homes, resort units — are especially exposed because a freeze can go unnoticed for weeks.
The signs after a cold snap
A sudden loss of pressure after a freeze, a damp patch in a crawlspace, or a water surge when the system thaws all point to a freeze-related split. In vacant properties, the first sign is often discovered only on the next visit.
Locating and preventing freeze-thaw leaks
Acoustic detection pinpoints the split on the pressurized line, and moisture assessment scopes the resulting damage. Just as important, locating the failure identifies the vulnerable run so it can be properly insulated or protected before the next winter — turning a recurring problem into a solved one.
