A hidden leak costs an average GTA homeowner thousands in water damage before it surfaces. Our P1 master plumbers locate the break with acoustic, thermal, and pressure-decay equipment — then repair copper, PEX, or slab to Ontario Building Code at a flat, posted rate with a 10-year warranty.
Locates leaks inside walls, under slabs, and underground — no exploratory demolition.
From a mystery high-water-bill leak to a cracked slab line, every Perruzza leak call starts with non-invasive detection and ends with a pressure-tested, warranted repair.
Acoustic listening devices, thermal imaging, and pressure-decay testing to locate hidden leaks inside walls, under slabs, and underground — without tearing open a single surface until we know exactly where to cut.
Systematic pressure-decay and flow-rate testing across your service line, main, and branch runs to confirm leaks, hidden restrictions, or failing pressure-reducing valves before they cause water damage.
Precision repair of pinhole leaks, split seams, corrosion failures, and freeze-damage breaks in copper, PEX-A, PEX-B, and CPVC supply lines — soldered, pressed, or crimped to Ontario Building Code.
Full slab-leak and buried-service-line repair from targeted core cuts to full re-routing — handled under permit with building department inspection so the repair holds for decades, not months.
Structural epoxy lining for aging supply mains, condo riser stacks, and branch runs — extends pipe life 50+ years without opening walls or ceilings throughout an occupied building.
