The most expensive plumbing repairs we see almost never start with a burst pipe. They start with a slow leak that ran unnoticed for months, soaking framing, drywall, and flooring along the way. By the time someone notices a stain, the repair bill has often grown from a service call into a five-figure restoration project.
Early warning signs
- A water bill that creeps up without a change in occupancy
- Musty smells in closets, storage rooms, or lower floors
- Paint or ceiling texture that bubbles, ripples, or discolors
- Warm spots on slab floors, which can point to a hot water line leak
- The sound of running water when every fixture is off
A simple monthly habit catches most of these: read the water meter, shut everything off, wait thirty minutes, and read it again. Movement on the meter with all fixtures closed means water is going somewhere it should not.
If you manage a multi-unit building, make leak checks part of every unit turnover and every seasonal inspection. Finding a drip under one sink is a ten-dollar washer. Finding it a year later is new cabinetry, new flooring, and a mold remediation invoice.
