Water heater repair cost by part.
Typical Madison repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Water heater repair in Madison typically costs between $175 and $800 for common repairs, plus a diagnostic fee of $85 to $225. Labor rates reflect the local median income of $74,895, and the city's older homes (median built 1978) often require more involved repairs. Wisconsin's state plumbing code (SPS 382-387) requires permits for most work, and only owner-occupants or licensed plumbers can perform repairs. Cold winter inlet water can stress units, making gas water heaters a common choice. The federal 25C tax credit (30%, up to $2,000) applies to heat pump water heaters, but gas remains typical.
