Slab leaks in Costa Mesa
Homes from 1960 to 1999 make up 67%, above the California figure of 55%. That ranks 33rd highest of the 151 California 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 California: Mountain and high-desert areas freeze hard in winter, unlike most of the coast.
