Water heater replacement cost by type.
Installed prices for Petaluma, adjusted for local labor. Larger tanks and code upgrades move the number up.

Sediment buildup
Hard water minerals accumulate over time, reducing efficiency and causing rumbling noises.
Corrosion and leaks
Older tanks (especially pre-1990) may rust from the inside, leading to leaks.

What to expect during replacement
A licensed plumber will disconnect the old unit, install seismic straps at the upper and lower one-third points, and add an expansion tank if needed. The job typically takes 4–6 hours. After installation, the plumber will pull a permit and schedule inspection with the city of Petaluma.
