Water heater installation cost by job.
Installed-labor pricing for Dunwoody, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Dunwoody homeowners replacing a water heater face costs that depend on unit type, fuel line work, and local code. A standard tank install runs $900–$2,000, while tankless runs $2,000–$5,000+. Adding a new gas line costs $325–$1,100. The typical home was built in 1984, so many systems are aging and may need code updates. Georgia requires a permit for water heater installation, and expansion tanks are mandatory on closed systems. The humid subtropical climate and moderate winter inlet water make heat-pump water heaters a strong fit—they qualify for the federal 25C tax credit (30%, up to $2,000).

Water Heater Installation in Dunwoody, explained.
What moves the price in Dunwoody
Labor rates reflect the local median income of $106,710, and permit fees add to the total. The unit type is the biggest factor: a standard tank is more affordable, while tankless requires higher upfront cost and often a new gas line. If your home lacks a drain pan and one wasn't previously installed, code doesn't require it, but adding one for peace of mind costs extra. Heat-pump units are pricier but eligible for a federal tax credit, lowering net cost.
Common installation issues in Dunwoody
Expansion tank requirement
Georgia code requires an expansion tank on closed systems; many older homes lack one, adding $50–$150 to the install.
Permit and inspection delays
A permit is required, and the inspection can slow down the job if not scheduled ahead. Some homeowners skip it, risking fines.
Aging gas lines
Homes built in 1984 may have undersized or corroded gas lines, requiring an upgrade for tankless units, costing $325–$1,100.
What to expect during installation
A licensed plumber will first obtain the required permit. They'll disconnect the old unit, install the new one per IPC Georgia amendments, and add an expansion tank if your system is closed. If you choose a heat-pump model, they'll handle the condensate drain. After installation, the city inspects the work. The job typically takes 4–8 hours for a standard replacement.
