Repair or replace?
A quick honest rule of thumb from our techs:
- Under 8 years old + minor part failure → repair
- 10+ years old, rusty water, or leaking tank → replace
- Rising gas bills + slow recovery → check burner or replace
- Popping/rumbling sounds → sediment; flush or replace
FAQ
- What size tank do I need?
- 1–2 people: 40 gal · 3–4 people: 50 gal · 5+ or big tubs: 75 gal. We'll confirm on-site.
- How long does a tank last?
- 8–12 years for most tanks. Annual flushes and anode inspection push that closer to 15.

From downtown Kirkland and the lakefront neighborhoods of Bellevue to the growing communities of Redmond, Bothell, and Woodinville, our licensed technicians understand the unique plumbing conditions in this region.

We specialize in gas and electric water heater installation using Rheem, A.O. Smith, and Bradford White tanks in 40, 50, and 75-gallon capacities. Every replacement includes a new temperature-and-pressure relief valve, drain pan, expansion tank, seismic straps, permit, and proper venting to Washington State plumbing and gas code. Whether you need a 40-gallon tank for a Bellevue condo, a 50-gallon upgrade for a three-bathroom home in Redmond, or a high-recovery 75-gallon unit for a busy family in Woodinville, we size the system for your actual household demand.
