Warning Signs
Spot the Signs Before the Damage Spreads
Even a small hidden leak can cause thousands of dollars in damage. If you notice any of these warning signs, call us for a fast, accurate inspection.
Unexplained Water Bill Spike
A sudden jump in your monthly bill is one of the clearest signs of a hidden leak.
Damp or Warm Spots on Floors
Warm or damp patches on the floor often point to a slab leak beneath the foundation.
Sound of Running Water
Hearing water run when every tap and appliance is off means water is escaping somewhere.
Musty Odors or Mold
Persistent damp smells or mold growth suggest moisture trapped behind walls or floors.
Cracks in Walls or Flooring
Shifting soil from a leak can crack tile, drywall and the foundation slab itself.
Dropping Pool Level
Losing more than a couple of inches of pool water per week usually means a leak.
Low Water Pressure
A sudden drop in water pressure can indicate a broken or leaking supply line.
Stains on Ceilings or Walls
Brown stains or bubbling paint reveal water where it should never be.
