Shower Valve Replacement in Hercules, California 94547
61% of homes were built before 1990.
Free to homeowners in Hercules — the contractor pays us for the introduction, you never do.
The short answer
In Hercules, 61% of homes predate 1990. A dripping shower is usually the cartridge; one that swings in temperature when another tap runs is usually the valve body, which sits behind the wall.

61% of Hercules housing was built before 1990. A valve that drips and a valve that cannot hold a temperature are two different faults with two different answers.
What this site is
ShowerValve is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands, and valve work opening a wall is often a permitted alteration — ask to see the permit. We carry out no work, we sell no valves, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call. The maximum water temperature is set by your local code, not by this website.Hercules in numbers

Shower Valve Replacement coverage in Hercules, CA
Hercules is in Contra Costa County, California. Its ZIP code is 94547. We route shower valve replacement calls from 94547.
Why the temperature swings
A valve that is not pressure-balanced sees the cold side drop when something else draws cold water, and the mix at the head follows it. That is the fault anti-scald valves were introduced to remove.
What points to the body rather than the trim
Water appearing inside the wall, in a ceiling below, or a handle that turns without changing anything, all point past the trim. None of them are fixed by a new escutcheon.
