Slab leaks in Jacksonville
Homes from 1960 to 1999 make up 50%, below the Florida figure of 59%. That ranks 22nd lowest of the 111 Florida 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 Florida: Homes built in the late 1970s through the mid-1990s may have polybutylene supply lines, which many insurers ask about.
