What affects the price
Replacing a water heater involves several variables that change the final bill. The main factors are the type of unit you choose—like standard tank models versus tankless systems—and the fuel source, whether gas or electric. Installation complexity also plays a role, especially if we need to update venting, gas lines, or electrical wiring to meet current building codes. Relocating a unit or upgrading to a higher capacity will also shift the bottom line.
About this service
An expansion tank is a small pressure-control vessel installed on the cold water supply line. Its purpose is to handle the extra volume of water created when it heats up and expands, preventing that pressure from damaging your pipes or the water heater itself. Many modern building codes now require these during new installations. If you see water dripping from your unit's pressure relief valve, it may be time to add or replace an expansion tank.
