Leak Detection in Pittsburgh
The expensive leak is the one you paint over. Water follows plaster keys and joists. The stain in the dining room can be a pin-hole in galvanized two rooms away.
What this actually is.
Leak detection is finding the pipe before someone opens four walls looking for it. In pre-war Pittsburgh houses that matters because plaster repair costs as much as the plumbing. Acoustic listening, moisture meters, and isolating fixture groups beat random demolition.
If water is actively spraying, you do not need detection. You need emergency shutoff and repair. If you only have a stain that grows, start here. Roof stains are a different trade — this desk is plumbing.
Galvanized is a usual suspect.
Homes built before about 1960 in Lawrenceville, Bloomfield, South Side, and parts of the East End still carry original galvanized supply. It clogs from the inside, then it pin-holes. Low pressure plus a new stain is often that system announcing itself. A matched plumber should be willing to say 'repipe this run' instead of soldering the same elbow three times.
Ballpark numbers.
Dedicated leak investigations in this market often run $200–$500 before repair. Opening a plaster wall and repairing a single copper pin-hole is one number. Replacing a galvanized run through two floors is another. Detection is how you find out which invoice you are actually facing.

Questions on this service
Can dye or food coloring find it?
Sometimes on a toilet. Rarely inside a wall. Do not flood a ceiling to 'confirm' the stain.
Is a slab leak common here?
Less common than in sunbelt slabs, but it happens on additions and on houses with in-floor heat. Basement ceiling leaks are the everyday version.
