Moisture that wicks up at a baseboard, with no plumbing fixture nearby, is often coming from below.
A new hairline crack, or a tile that rocks underfoot, deserves a look before it spreads.
Hot water running short
Showers go lukewarm sooner than they used to.
Pressure slowly fading

The method

Split hot from cold
Closing the valve on the water heater shows whether the loss is on the hot side. That single step decides which tools come out next.
Isolate the failing branch
Listen through the concrete
Ground microphones pick up the sound of water escaping under pressure, and the sound peaks close to the failure.

Mark it and explain the options
Tape goes down over the failure, the readings are noted for you, and you hear which repairs would work in your house and why, with no quote attached yet.

The process runs from simple to precise: meter check, gauge test, hot-versus-cold split, branch isolation, then listening and thermal equipment to pin down the point.
