Seattle, Wash. – Late-winter temperature swings and prolonged moisture are driving pipe failures across Washington homes just weeks before spring arrives.
Plumbing professionals say the transition from winter to spring is one of the most damaging periods for residential plumbing in the Pacific Northwest. While Washington winters are often milder than in the Midwest, repeated freeze-thaw cycles combined with persistent damp conditions can weaken pipes over time.
In cities such as Seattle and Spokane, the risk varies by region but remains significant. Western Washington homes often experience slow-forming damage caused by moisture and brief freezes, while eastern Washington sees sharper temperature drops that can cause pipes to freeze and crack more abruptly.
Pipes located in basements, crawl spaces, garages, and exterior walls are especially vulnerable. Hairline fractures formed during winter may not leak immediately, but once temperatures rise and water use increases in late winter or early spring, those weakened pipes can fail suddenly.
Many homeowners discover problems when reconnecting outdoor hoses, increasing household water use, or beginning spring cleaning. Warning signs may include fluctuating water pressure, damp spots near walls or ceilings, corrosion on exposed pipes, or outdoor faucets that drip when turned on.
Plumbers across Washington report that early spring consistently brings a rise in emergency service calls. Many of those repairs are linked to winter damage that went unnoticed during colder months. As demand increases, wait times and repair costs often rise.
Younger homeowners and first-time buyers are frequently caught off guard by sudden pipe failures, which can damage flooring, furniture, and electronics. Renters may also face service disruptions if urgent repairs are required.
Experts recommend inspecting exposed pipes now, testing faucets for pressure changes, draining and disconnecting outdoor hoses, and insulating plumbing in unheated areas. Addressing pipe stress before steady spring temperatures arrive can help prevent costly water damage during Washington’s seasonal transition.
