Water heater replacement cost by type.

In Dundalk, Maryland, replacing a water heater involves specific local considerations. With a median home age of 71 years, many homes have older plumbing that may require updates during replacement. Labor costs in this Baltimore suburb reflect the need for a Maryland-licensed master plumber and a final inspection per the International Plumbing Code. Typical installed prices range from $750–$1,900 for a tank gas unit, $850–$2,100 for tank electric, $1,450–$3,400+ for tankless, and $1,750–$3,800 for a heat pump water heater.
