Water heater replacement cost by type.
Installed prices for Franklin Lakes, adjusted for local labor. Larger tanks and code upgrades move the number up.
Water heater replacement in Franklin Lakes typically costs between $750 and $3,700, depending on the unit type and installation complexity. With most homes built around 1979 and high homeownership (85.6%), many older tanks need replacement due to age or sediment buildup. New Jersey requires a permit for all water heater replacements, and the work must comply with the 2021 National Standard Plumbing Code (NSPC) under the Uniform Construction Code. Given the cold winter inlet water and predominance of gas heating, a gas tank or tankless unit is often a strong fit for local homes.
