Complete Water Heater Services in Greater Seattle
Whether you need a quick water heater repair, a brand-new tankless system, or a like-for-like tank replacement, our licensed Seattle plumbers handle the entire job, from removing the old unit to permitting and final inspection.
Tank vs. Tankless: Which Is Right for You?
Traditional tank heaters store 40–80 gallons of pre-heated water and have a lower upfront cost. Tankless units heat on demand, they cost more to install but last longer, save energy, and provide unlimited hot water.
- Tank: lower install cost, simpler service
- Tankless: 20+ year lifespan, endless hot water
- Tankless: 25–35% energy savings
- Tankless: frees up floor space
24/7 Emergency Water Heater Service
Leaking tank? No hot water in the middle of winter? Our emergency team is on call around the clock to diagnose and resolve water heater failures before they damage your home.
Water Heater Maintenance
Annual maintenance extends your water heater's life by 5–10 years. We flush sediment, test the anode rod, check pressure, and verify all safety devices are working correctly.
