Water heater replacement in Sacramento, CA, often same day
A new heater is only as good as the install behind it.

We remove the old tank, install a correctly sized gas or electric heater with new connectors, seismic straps, expansion tank where needed, proper venting and a piped relief line, then haul the old unit away.
What water heater replacement covers
Most replacements are like-for-like: a 40 or 50 gallon gas tank swapped for a new one in the same spot. Even then, the details matter. Venting has to be the right size and slope, the relief valve needs a full-size discharge line, the gas connector should be new, and the tank must be strapped.
If you have been thinking about tankless or a heat pump water heater, replacement time is when to decide. We price the options side by side so you can compare up-front cost against operating cost.

Water Heater Replacement questions
Can you replace my water heater the same day?
Often, yes, for standard sizes we stock. Special models may take a day or two to arrive.
Do I need an expansion tank?
If your home has a pressure regulator or a check valve at the meter, the system is closed and an expansion tank is needed to absorb heated water.
Should I go bigger?
Only if you are running out. A larger tank costs more to keep hot. We help you size it to real use.
