🚨 Pipe Just Burst? Do This Now.
- Shut off the main water supply — usually at the water meter or where the line enters the house
- Turn off the water heater — prevents heating an empty tank
- Open a cold faucet — relieves remaining pressure
- Document everything — photos and video before cleanup (for insurance)
- Call a licensed plumber + water damage company — you need both if floors or walls are soaked

Local context: Seattle has ultra-soft water from Cedar River and Tolt River watersheds (15–30 ppm). Soft acidic water has corroded copper pipes throughout the city's 1940s–1970s housing stock, creating a rash of pinhole leak failures. Amazon/tech economy means highest labor rates in the Pacific NW.
The pipe repair itself is usually the smaller cost. Water damage remediation — drying walls, flooring, and preventing mold — typically costs $1,500–$10,000+ depending on how long water was flowing. Call a water damage company at the same time as the plumber.

Frequently Asked Questions
How much does burst pipe repair cost in Seattle?
Accessible burst pipe repair in Seattle costs $275–$2100. Pipes inside walls or slabs cost $700–$5600 due to access and restoration requirements. Water damage remediation (drying, mold prevention) is billed separately and typically costs $1,500–$10,000+ depending on how long water was flowing.
What should I do immediately when a pipe bursts?
1. Shut off the main water valve immediately. 2. Turn off your water heater. 3. Open a cold-water faucet to drain pressure from the line. 4. Call an emergency plumber AND a water damage company. 5. Document all damage with photos before any cleanup — critical for insurance.
Does homeowners insurance cover burst pipe repair?
Usually yes for sudden, accidental bursts — but NOT for gradual leaks or negligence (like not winterizing before a freeze). Most policies cover water damage remediation but not the pipe repair itself. File your claim before cleanup begins and keep all receipts.
Why do pipes burst in Seattle?
In Seattle, burst pipes are most common in older homes with aging galvanized steel or cast-iron pipes past their service life. High water pressure (above 80 psi) is also a frequent cause — a pressure reducing valve (PRV) is a cheap preventive fix.
How long does burst pipe repair take?
A single accessible burst pipe takes 1–3 hours to repair. If walls, ceilings, or floors need to be opened, add time for access, repair, and restoration. Full water damage drying takes 3–5 days minimum. Verify the plumber's license at https://lni.wa.gov/licensing-permits/plumber/ — burst pipe emergencies are a prime target for unlicensed contractors.
