Leak Detection Services in
Albert Lea, MN

Traditional leak detection involved drilling holes in walls, chipping up concrete, and excavating yards of flooring on the basis of educated guesses — causing thousands of dollars in structural damage before the leak was ever found. John Plumbing & Drain Cleaning has eliminated that approach entirely. Our acoustic listening devices amplify the ultrasonic sound signature of pressurized water escaping from a pipe — a distinctive frequency that our trained technicians track through concrete slabs, packed soil, wall cavities, and ceiling structures. We pinpoint your leak location within inches without touching a single tile.

Our FLIR-grade thermal imaging cameras detect temperature differentials invisible to the naked eye. A hot-water slab leak creates a heat plume that radiates upward through your concrete floor — clearly visible on our thermal display as an anomalous warm zone. Cold-water leaks create corresponding cool zones in walls and ceilings as evaporation occurs. This technology lets us map the leak's extent without lifting flooring, cutting drywall, or disturbing your living space in any way.

For deep or underground leaks that challenge even acoustic detection — buried main lines, leaks beneath thick reinforced slabs, or leaks under dense hardscape — we deploy tracer gas technology. A safe, inert hydrogen/nitrogen gas mixture is introduced into the isolated pipe section under pressure. The gas, being lighter than air and highly mobile through porous materials, rises through the soil and concrete and escapes at the surface directly above the breach. Our sensors detect this gas at parts-per-million concentration, triangulating the exact surface point above the leak within inches.

Once we locate your leak, we provide a complete written report with the precise location, estimated severity, and a full menu of repair options. For slab leaks, these options typically include traditional targeted excavation and spot repair (minimum concrete removal), epoxy pipe lining that seals the leaking section from the inside without any concrete work, or pipe rerouting that bypasses the compromised section entirely. We present the honest costs and long-term implications of each so you choose with complete information.
