Water heater installation cost by job.
Installed-labor pricing for Lanham, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Lanham, Maryland, water heater installation costs typically range from $750 to $1,700 for a standard tank unit and $1,700 to $4,200+ for a tankless system. With a median home built in 1969, many homes may require updates to venting, gas lines, or electrical systems to meet current code.

All installations must be performed by a Maryland-licensed master plumber and require a permit with final inspection to verify T&P discharge, venting, and connections.
