What Is Professional Leak Detection?
Leak detection uses acoustic sensors, thermal imaging, and moisture meters to pinpoint leaks behind walls, under slabs, and inside ceilings without destructive exploration.
A spike in your LADWP bill, mysterious damp spots, or the sound of running water when everything is off are all red flags. The longer a hidden leak runs, the more damage it causes.
Poppy Plumbing identifies the exact location so repairs are surgical, not exploratory. When we find a slab leak, we explain your repair options with clear upfront pricing.
