Wilmington, Delaware – As the winter solstice arrives this Sunday, colder overnight temperatures across Delaware are increasing the risk of frozen pipes, placing homes in Wilmington at heightened risk for water damage as winter settles in. Extended hours of darkness paired with sustained cold can cause pipes to freeze quickly, especially in older homes and buildings near the Delaware River.
According to the National Weather Service and the Delaware State Fire Marshal, pipes located in unheated basements, crawl spaces, attics, and exterior walls are most likely to freeze during prolonged cold spells. When frozen pipes begin to thaw, internal pressure can cause cracks or bursts, releasing significant water into living spaces within minutes.
In Wilmington, residents are urged to insulate exposed pipes, seal cracks around vents and foundation openings, and keep thermostats set no lower than 55 degrees, even when leaving home. Allowing faucets to drip slightly overnight can also help keep water moving and reduce freezing risk. Opening cabinet doors under sinks allows warmer air to circulate around plumbing.
Fire officials strongly warn against using blowtorches, open flames, or propane heaters to thaw pipes due to serious fire hazards. If water flow drops or leaks appear, shutting off the main water valve immediately can limit damage.
Cold conditions are expected to persist into early next week, and additional winter safety advisories may be issued as temperatures fluctuate.
