Slab leaks in Tucson

Homes from 1960 to 1999 make up 64%, above the Arizona figure of 57%. That ranks 10th highest of the 29 Arizona cities we profile. Hot lines under the slab expand and rub against concrete for decades until a pinhole forms.

Leak detection confirms the leak at the meter, isolates hot from cold, then pinpoints it acoustically so only one small spot is opened, or none if a reroute is the better fix.

In Arizona: Summer heat bakes water heaters in garages and exposed irrigation lines, while rare winter freezes crack backflow assemblies.

Warm spot on your floor? It may be a slab leak. A warm patch on a tile or concrete floor often means a hot-water line is leaking under the slab. (Illustrative AI-generated clip, no sound.)

What to do first

  • Turn off every fixture and watch the meter's leak dial
  • Shut the cold inlet valve on the water heater to see if the meter stops
  • Photograph warm spots and bills for your insurer

What affects the price

  • Number of lines and branches to isolate
  • Floor covering over the suspected area
  • Access to the manifold or water heater
  • Whether multiple leaks are present
