Water heater installation cost by job.
Installed-labor pricing for Mount Vernon, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Mount Vernon, Virginia, homeowners typically pay between $750 and $1,700 for a standard tank water heater installation, while tankless models run $1,700 to $4,200 or more. With a median home age of 59 years, many homes may need updates like a new gas line ($275–$950) or an expansion tank (required on closed systems per Virginia code).
