During Saskatoon’s long winter months, hidden plumbing leaks can go unnoticed—until frozen water expands and causes serious damage. Early detection saves you money, prevents mold, and protects your pipes from bursting. Here’s how to identify leaks hiding behind walls, under floors, or inside ceilings before they become costly emergencies.
Why Leaks Are More Dangerous in Winter
- Low humidity causes seals and joints to contract.
- Frozen water expands, cracking weak fittings.
- Reduced water use can mask minor drips until they freeze solid.
A small leak in December can become a major flood by February if left unchecked.
Common Signs of a Hidden Leak
- Unexplained increase in water bills.
- Musty odours or damp spots on walls.
- Warm or discoloured flooring.
- Low water pressure or running water sounds behind walls.
Pro Service Mechanical recommends checking utility rooms, under sinks, and near exterior walls regularly during winter months.
Areas Most at Risk in Saskatoon Homes
- Basements and crawl spaces.
- Behind bathroom and kitchen walls.
- Near water heaters and laundry areas.
- Outdoor spigots or garage plumbing.
Because these zones experience extreme cold, even minor leaks can freeze rapidly, leading to burst pipes.
How to Detect and Fix Leaks Early
- Monitor your water meter for usage when no taps are running.
- Use a moisture detector or infrared camera to find hidden dampness.
- Check caulking and joints near plumbing fixtures.
- Call a licensed plumber to pressure-test your system.
Our technicians use non-invasive leak detection tools to pinpoint exact problem areas without unnecessary wall damage.
