Water heater installation cost by job.
Installed-labor pricing for Fond du Lac, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Fond du Lac, Wisconsin, typically costs between $700 and $1,600 for a standard tank unit, and $1,600 to $3,900+ for a tankless system. With many homes built around 1967, older plumbing and gas lines may require upgrades, adding $275–$900 for a new gas line. Fond du Lac's cold winters mean cold inlet water, so a gas unit is recommended for efficient recovery. Wisconsin's state plumbing code (SPS 382-387) requires a permit for installation, and only owner-occupants or licensed plumbers can perform the work. The federal 25C tax credit offers 30% back (up to $2,000) for heat pump water heaters, but gas remains the more common choice locally.
