Water heater installation cost by job.
Installed-labor pricing for Dundalk, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Dundalk, Maryland, water heater installation costs typically range from $750 to $1,750 for a standard tank unit and $1,750 to $4,300+ for a tankless system. With a median home age of 71 years, many homes have older plumbing that may require updates during installation. Maryland requires a permit and inspection by a licensed master plumber, and an expansion tank is needed if a check valve or backflow preventer is present. Given the humid subtropical climate and cold winter inlet water, a heat pump water heater is a recommended choice for efficiency, though it has a higher upfront cost.
