Water heater installation cost by job.
Installed-labor pricing for Alton, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Alton, Illinois, where the median home was built in 1952 and winter inlet water is cold, water heater installation costs typically range from $650 to $1,500 for a standard tank unit and $1,500 to $3,800+ for a tankless system.
