Water heater installation cost by job.
Installed-labor pricing for Leander, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Leander, Texas, where the median home was built around 2011, many water heaters are now 15 years old and nearing the end of their lifespan. A standard tank installation typically runs $900–$2,000, while tankless units cost $2,000–$5,000 or more, depending on gas line upgrades ($325–$1,100). Texas law requires a licensed plumber and a permit with inspection for any water heater replacement, and expansion tanks are required on closed systems. With hot summers and moderate winter inlet water, a mixed unit type is recommended. The federal 25C tax credit offers up to $2,000 for qualifying heat pump water heaters, but local utility rebates vary.

Gas Line Upgrades for Tankless
Many Leander homes built around 2011 have standard 1/2-inch gas lines, but tankless units often need 3/4-inch lines, costing $325–$1,100 for the upgrade.
What to Expect During a Water Heater Installation in Leander
A licensed plumber will first assess your current setup and obtain the required permit. The job includes disconnecting and removing the old unit, installing the new water heater (with expansion tank if needed), and connecting gas and water lines. A final inspection by the city is required. Typical installation takes 3–6 hours for a tank replacement, longer for tankless due to gas line work.
