Water heater installation cost by job.
Installed-labor pricing for Marietta, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Marietta, Georgia, water heater installation costs typically range from $800 to $1,800 for a standard tank unit and $1,800 to $4,500 or more for a tankless system. With a median home age of 41 years, many homes may need upgrades like a new gas line ($300–$1,000) or an expansion tank (required on closed systems per Georgia code).

Local permits are required, and installation must follow the International Plumbing Code with Georgia amendments.

Aging Home Infrastructure
Many Marietta homes are over 40 years old, with older plumbing or gas lines that may need upgrading to meet current code, increasing installation complexity and cost.

What to Expect During Installation

They'll disconnect and remove the old unit, install the new water heater (including an expansion tank if required), and test for leaks. The job usually takes 2–4 hours for a standard tank replacement, longer for tankless or if gas line work is needed.
