A hidden water leak can cause thousands in damage before you notice it. Big League's licensed plumbers locate and fix leaks inside walls, ceilings, slabs, and foundations across Vaughan.
Hidden leaks are among the most damaging problems in a home because they often go undetected for months. By the time visible damage appears — a water stain on your ceiling, a soft spot in the drywall, or a wet patch on the floor — significant structural damage may already be occurring inside your walls or under your slab. Watch for unexplained increases in your water bill, the sound of running water when all fixtures are off, musty odours in rooms with no obvious moisture source, and warm spots on floors that may indicate a hot water line leak beneath the concrete.
Professional leak detection goes beyond guesswork. At Big League, our technicians use pressure testing and systematic fixture isolation to pinpoint leaks without tearing open walls unnecessarily. We trace the plumbing system methodically — isolating sections to identify exactly where pressure is dropping — and use our Instant Replay Video documentation to show you the evidence before any repair work begins. If the leak is accessible, we can often repair it same-day.
Leak detection in Vaughan typically ranges from $185 to $395 depending on the complexity of the system and the number of areas to be tested. If we find the leak and you proceed with the repair, the diagnostic portion is absorbed into the job price. We never charge for findings we can't substantiate — if we don't find a leak, we tell you exactly what we ruled out and what to monitor going forward.
