When the hot water stops, the first question is whether the heater needs a part or a funeral. Plenty of no-hot-water calls come down to a failed element, a tripped thermostat, a bad thermocouple or a pilot that will not stay lit, all repairs, not replacements.
The honest version of this service is diagnosing before condemning. A tank that is sound but not heating is worth repairing; a tank that is leaking from the body is not, because the leak means the shell has corroded through and no repair brings that back.
What is actually wrong
On an electric heater, no hot water is usually an element or a thermostat, and lukewarm-then-cold often means the lower element has failed while the upper still works. On a gas unit, a heater that will not light points at the thermocouple, the pilot assembly or the gas valve. These are the repairs that get a working heater back the same day.
Not enough hot water is a different complaint. It can be sediment insulating the bottom of the tank, a failing element, or simply a tank too small for how the household's demand has grown. The rumbling many people hear is sediment, and flushing it is part of getting the capacity back.
Diagnose before deciding
Find the fault
Element, thermostat, thermocouple or sediment each fail in a recognizable way.
Repair where it is worth it
A sound tank with a bad part is fixed, not replaced.
Be straight about the tank
A leaking body means the tank is done, and we say so rather than sell a doomed repair.

When a repair is throwing good money after bad
A repair stops making sense when the tank is both old and leaking. Once the shell corrodes through, the water on the floor is the tank telling you its life is over, and a new element will not change that. The fair answer there is replacement, not a part.
The dividing line is usually age and the source of the leak. A drip from a fitting or a valve is a repair. Water seeping from the body of a ten-plus-year tank is the end. Knowing which you have is the whole point of the diagnosis.
Renton water heater repair questions
I have no hot water. Does the heater need replacing?
Not necessarily. No hot water is often a failed element, thermostat or thermocouple, which is a repair on an otherwise sound tank. Replacement is only the answer when the tank body itself is leaking or the unit is well past its life.
Why does the hot water run out so fast now?
Commonly sediment built up in the bottom of the tank, which insulates the burner or element and cuts usable capacity. Flushing the tank and checking the element usually restores it, short of the tank simply being too small for the household.
Is a leaking water heater always a replacement?
If the leak is from the tank body, yes, because the shell has corroded through. If it is from a fitting, a valve or a connection, that is a repair. Locating the leak is the first thing to settle.
Can you repair it the same day?
Common parts faults are usually a same-day fix where the tank is worth saving. A leaking tank body is treated as urgent but points toward replacement rather than repair.
Can a water heater usually be fixed the same day?
Common faults can, because the parts involved are standard: an element or thermostat on an electric unit, a thermocouple, pilot assembly or gas valve on a gas one. Those are diagnosed and replaced on a tank that is otherwise sound. The exception is a tank leaking from its body, which means the shell has corroded through and points to replacement rather than a repair, so the first thing checked is where any water is actually coming from.

When the diagnosis is a corroded tank, the honest path is water heater installation and replacement.
If the household keeps outrunning the tank, a tankless water heater ends the runs-out complaint for good.
