What this project involves
Replacing a water heater covers removing the old unit, setting the new tank or tankless system, reconnecting water, gas or electrical, updating the venting and pressure relief line, and hauling the old unit away. Estimt builds a preliminary planning range from your answers, then routes your project to plumbing professionals in your ZIP code.

AI estimates are preliminary planning ranges, not binding contractor quotes. Actual costs may change after professional inspection based on project scope, materials, permits, access, local requirements, and hidden conditions.
What changes the price
Tank vs tankless
Tankless units cost more up front and usually need gas and venting changes.
Capacity and fuel
Larger tanks, heat pump units and electric conversions change the total.
Access
Attic, crawlspace or tight closet installs take longer than a garage swap.
Permits and code
Local inspection, seismic strapping and expansion tanks may be required.
Emergency timing
After-hours or same-day work when a tank has failed can cost more.
