Water heater repair cost by part.
Typical Hanahan repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Water heater repair in Hanahan typically costs between $125 and $600 for common repairs, plus a $65–$175 diagnostic fee. With most homes built around 1988, many units are nearing the end of their lifespan, and local codes require permits for replacements. The humid subtropical climate and moderate winter inlet water mean electric water heaters are common, but heat pump models are a strong fit for energy savings. South Carolina follows the 2021 IPC, so expansion tanks are required on closed systems, and permits are mandatory even for like-for-like replacements.

Sediment buildup
Hard water minerals accumulate over time, reducing efficiency and causing rumbling noises. Flushing the tank can restore performance.
Thermostat or element failure

Leaking pressure relief valve
A faulty T&P valve can leak water, often due to high pressure or sediment. Replacement is straightforward but requires proper handling.
