Why Leak Detection Matters in Scarborough
Hidden water leaks are one of the most damaging plumbing problems homeowners face. A small leak behind a wall or under a floor can go undetected for months, causing mould growth, structural damage, and dramatically inflated water bills.
Scarborough homes are particularly susceptible due to several factors: the area's notoriously hard water accelerates pipe corrosion and mineral buildup, older homes (many built in the 1950s–1970s) have aging copper and galvanized steel pipes, and freeze-thaw cycles during Ontario winters cause pipe joints to weaken over time.
Signs You May Have a Hidden Leak
- Unexplained increase in water bills: If your usage hasn't changed but your bills keep rising, a hidden leak is the most likely cause
- Damp or discoloured patches: Stains on walls, ceilings, or floors that appear without an obvious source
- Musty or mouldy smell: Persistent dampness behind walls creates ideal conditions for mould
- Sound of running water: If you hear water flowing when all taps and appliances are off
- Low water pressure: A sudden drop in pressure can indicate water escaping from a damaged pipe
- Water meter running: Turn off all water in your home and check if the meter is still moving
- Cracking in foundation or walls: Persistent leaks can erode soil around foundations, causing settling
Detection Technology
Modern leak detection uses non-invasive technology to pinpoint leaks without tearing open walls or floors:
- Acoustic Detection: Sensitive microphones detect the sound of water escaping from pressurized pipes, even through concrete and soil
- Thermal Imaging: Infrared cameras detect temperature differences caused by moisture, identifying leak locations behind walls and under floors
- Tracer Gas Detection: A safe, non-toxic gas is introduced into the plumbing system and sensors detect where it escapes
- Moisture Meters: Electronic meters measure moisture levels in walls, floors, and ceilings to map the extent of water damage
