Water heater installation cost by job.
Installed-labor pricing for DeSoto, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in DeSoto, Texas, typically costs between $850 and $1,900 for a standard tank unit, and $1,900 to $4,700 or more for a tankless model. These prices reflect local labor rates, permit fees, and any necessary gas line upgrades ($325–$1,050). With a median home built in 1993, many homes may need code updates like an expansion tank on closed systems.
