What it costs across Mississippi
Water Heater Replacement
Water heater replacement cost depends on the unit type, size, fuel source, and what code upgrades the job triggers. A basic 40-gallon gas tank swap and a high-efficiency tankless install can sit nearly $4,000 apart.
Water Heater Installation
Water heater installation cost covers the labor and parts to fit a new unit — whether it's a first-time install, a fuel switch, or a tankless conversion. The number swings with venting, gas-line work, and whether the location changes.
Water Heater Repair
Water heater repair cost depends on the failing part and whether the unit is gas or electric. Most common repairs — thermostats, elements, thermocouples, valves — land between $150 and $800 including labor.
