Repair vs. Replace: The Oregon Plumber's Rule
We use a simple framework when homeowners ask us whether to repair or replace. If the repair cost exceeds 50% of the cost of a new unit AND the unit is over 7 years old, replacement almost always makes more financial sense. Here's why:
- A repaired water heater with a failing anode rod or degraded lining is likely to fail again within 2–3 years
- New units come with 6–12 year manufacturer warranties, meaning no repair bills during that window
- Modern units are 15–30% more energy efficient than units from 2015 or earlier
- The total cost of a second repair shortly after the first almost always exceeds the cost of a new unit installed today
We've seen this play out hundreds of times across Beaverton, Tigard, and Lake Oswego. The homeowner who spent $400 on a thermostat repair often calls us back 18 months later for a full replacement after the tank develops a leak — and at that point the thermostat money is simply gone.
How to Get an Accurate Quote in Washington County
Accurate pricing requires seeing the unit in person. The variables that determine your actual cost include: fuel type (gas vs. electric), current venting configuration, unit location (garage, basement, crawlspace), whether permits are required, and whether any code upgrades are needed (expansion tank, seismic strapping, drain pan). We account for all of this in our free on-site estimate — nothing hidden, nothing added later.
