When to call a plumber
Any visible leak, damp spot or pressure drop needs fast attention. A neglected leak damages floors, walls and ceilings and can grow into a mold problem.
What affects the price
Location is everything — an exposed pipe is cheap, a hidden wall or slab leak is not. Detection work (moisture meters, cameras) adds cost. Emergency after-hours calls cost more.
