Slab leaks in Wilmington
Homes from 1960 to 1999 make up 50%, below the North Carolina figure of 52%. That ranks 8th highest of the 16 North Carolina 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 North Carolina: Crawl-space construction is common, and hard freezes in the mountains and Piedmont crack exposed pipes.
