Water heater installation cost by job.
Installed-labor pricing for Stoneham, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Stoneham, Massachusetts, where the median home was built in 1963, water heater installation often involves replacing aging units. With cold northern winters and cold inlet water, a standard tank installation typically runs $750–$1,700, while tankless systems range $1,700–$4,200+.
