Shower Valve Replacement coverage in Hazelwood, MO
Hazelwood is in St. Louis County, Missouri. Its ZIP code is 63042. We route shower valve replacement calls from 63042.
Cartridge or valve body
A shower that drips is usually the cartridge, which is a part. A shower that will not hold a temperature when a tap runs elsewhere is usually the valve, which is behind the wall.
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.

Checking a plumber in Missouri
Missouri has no state plumbing board. Section 341.010 of the Revised Statutes requires a certificate for plumbers working in cities or towns of fifteen thousand or more inhabitants, and the chapter elsewhere recognizes licenses issued by any county or city operating under plumbing rules, so the office that issued one is a local office. Start here. Ask the contractor which municipality licenses them and confirm it with that office before work begins.
