A water heater that's rumbling, leaking, or running lukewarm doesn't always need to be replaced. Casteel plumbers start with a full diagnosis so you know exactly what's wrong and whether a repair will restore reliable hot water.
If your unit is past the point of a smart repair, we'll be upfront about what comes next — whether that's a straightforward replacement or an upgrade. Water heater pricing for a new system from Casteel runs from $2,300 to $17,000, and most straightforward tank replacements fall toward the lower end of that range. Higher-end systems — with added capacity, smart controls, and longer warranties — along with high-efficiency tankless upgrades for larger homes, sit at the top of that range for homeowners who want more from their system.
Why water heater pricing varies across greater Atlanta
Every home is different. A gas tank in the garage is a simpler job than an attic installation in a two-story home or a tankless conversion that needs new venting. Capacity, fuel type, drain pan and code requirements, and access all play a role — and so does who's doing the work. Every Casteel plumber is licensed, background-checked, and drug-tested, with years of hands-on replacement experience behind every install. Your plumber explains each factor and gives you a clear price before any work begins.

If your tank is leaking, corroded, or nearing the end of its lifespan, replacement often delivers better value. Repair can make sense when the unit is relatively young and the problem is an isolated part, like a thermostat, heating element, or thermocouple. Your Casteel plumber will walk you through both options.
New water heater costs from Casteel range from $2,300 to $17,000. Where your home falls depends on the type of heater (tank or tankless), fuel source, capacity, and installation conditions such as venting, gas lines, and code requirements. Your plumber will provide an exact, upfront price before any work begins.
A like-for-like tank replacement and a whole-home tankless conversion are very different jobs. Tankless units cost more to buy and often need new venting, a larger gas line, or electrical upgrades. Hard-to-reach locations and permit or code updates also add labor. That's why every Casteel quote is based on your home.
Schedule a visit and a Casteel plumber evaluates your current system, your household's hot water demand, and the installation space, then presents your options with upfront pricing. You'll know the full price before any work begins, and same-day and 24/7 emergency service is available.
