Water heater installation cost by job.
Installed-labor pricing for Catonsville, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Catonsville, Maryland, water heater installation costs typically range from $800 to $1,800 for a standard tank unit and $1,800 to $4,600+ for a tankless system. With a median home age of 62 years, many homes require updates to meet current code, such as adding an expansion tank on closed systems. Maryland requires a permit and final inspection by a licensed master plumber, which adds to the overall cost. Given the humid subtropical climate and cold winter inlet water, a heat pump water heater is a recommended choice for energy efficiency, though it may qualify for a federal 25C tax credit of up to $2,000.
