Leak Detection & Repair in Mattoon, IL

The most expensive leaks are the ones you can't see. A pipe behind a wall or under the slab can run for weeks before it shows up as visible damage. Here's what to watch for.

Signs of a hidden leak

  • Your water bill jumped with no real change in how much water you're using
  • You hear running water somewhere in the house when everything is off
  • A warm or unexpectedly cold spot on the floor, often a sign of a leaking line under a slab
  • A musty smell in a room that should be dry, with no obvious source
  • Water stains or discoloration on a wall or ceiling
  • Your water meter's flow indicator is still moving when nothing is using water

The 20-minute meter test

  • Turn off every faucet, appliance, and fixture in the house, nothing running, nothing flushing
  • Write down your water meter reading, or note whether the small flow indicator is spinning
  • Wait 20 minutes without using any water
  • Check the meter again, if the reading changed or the indicator is still moving, water is escaping somewhere

Hidden and slab leaks generally aren't something you can pinpoint yourself. If the meter test comes back positive, reach out and we'll help track down exactly where it's coming from.
