Water heater replacement cost by type.
Installed prices for Williamsburg, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Williamsburg, Virginia, replacing a water heater typically costs between $650 and $3,400, depending on the type and installation complexity. With a median home age of 41 years, many homes have older units that may need replacement. Local permits are required even for like-for-like swaps, and the Virginia Plumbing Code (IPC-based) mandates expansion tanks on closed systems. Given the humid subtropical climate and moderate winter inlet water, heat pump water heaters are a strong fit, offering efficiency and eligibility for the federal 25C tax credit (30% up to $2,000). Labor rates reflect the local market, and prices vary by unit type: tank gas ($650–$1,700), tank electric ($750–$1,850), tankless ($1,250–$2,900+), and heat pump ($1,500–$3,400).

Leaking tank

Pilot or ignition failure
Gas units may have faulty thermocouples or igniters. In older homes, gas line issues can also cause problems.
