Spot the Signs Before the Damage Grows

 

  • A sudden jump in your water bill
  • Musty smells or mold growth
  • Stains or bubbling paint on ceilings or walls
  • Pooled water or damp spots on floors
  • Decreased water pressure

Leaks aren’t always visible. You may not see them—but you’ll definitely feel their impact. If anything seems off, don’t wait. Catching a leak early can save you thousands in repair costs.

Advanced Leak Detection Without the Mess

  • Thermal Imaging: Identifies hidden moisture behind walls and under floors
  • Acoustic Listening Devices: Pinpoint leaks based on sound, even underground
  • Pressure Testing: Detects drops that indicate hidden pipe damage
  • Moisture Meters: Verify moisture levels to confirm affected areas
