Water heater replacement cost by type.
Installed prices for St. Marys, adjusted for local labor. Larger tanks and code upgrades move the number up.
In St. Marys, Georgia, water heater replacement costs typically range from $650 to $3,400 depending on the type and complexity. The median home was built in 1994, so many homes have aging units that need replacement. Local codes follow the International Plumbing Code with Georgia amendments, requiring permits for replacements.
