Slab leaks in master-planned residential.
Copper supply lines fail at fittings or pinhole through corrosion across master-planned residential from central and northern Mission Viejo through the Lake Mission Viejo communities — often invisible until flooring buckles or the water bill spikes. We locate with acoustic or thermal detection, make controlled slab access, repair, and dry to standard, with high mold risk if not dried within 48–72 hours.
