Even in California’s mild climate, pipes can freeze when temperatures drop below 32 degrees, especially in unheated areas. Pipes in garages, attics, crawl spaces, and along exterior walls are most vulnerable.
Cold air leaks into homes through small gaps around windows, doors, and foundations. While your thermostat might read 55 degrees, the temperature inside exterior walls can be 20-30 degrees colder. This is enough to freeze water in pipes.
Sheridan homeowners often get caught off guard because frozen pipes aren’t common here. But when cold snaps hit, pipes that aren’t properly insulated can freeze within hours, especially overnight when temperatures drop lowest.
