Reliable Local Leak Detection Specialists
Local water leak detection for Mount Colah homes and strata
For more than 10 years, Pro Leak Waterproofing has helped property owners locate hidden leaks across Mount Colah and the Upper North Shore, from older brick homes to modern strata buildings.
Homes and strata buildings across the Upper North Shore include older brick houses, split-level homes, duplexes, townhouses and apartments, many on leafy, shaded and sloping streets. Heavy rain, stormwater runoff, blocked gutters, poor drainage and ageing waterproofing membranes can cause hidden leaks. The first signs are often damp walls, mould, ceiling stains, peeling paint and cracked tiles.
Focused water leak detection in Mount Colah helps you make the right repair the first time. Instead of opening walls and floors on a hunch, we use acoustic correlation, thermal imaging and pressure testing to confirm exactly where water is escaping. You save money on unnecessary demolition, the repair is targeted and your Mount Colah property is protected before damage spreads.
From underground pipe leaks, leaking showers and balcony ingress to ceiling stains and rising water bills, our team finds the leak, proves the source and carries out the proper fix.
