Signs You Have a Plumbing Leak in St. Catharines
Most leaks stay hidden until the damage is done.
If you notice any of the following, there’s a good chance a plumbing leak in your St. Catharines home or business is quietly getting worse:
- A water bill that jumped without any change in your habits
- Damp spots, stains, or bubbling paint on walls and ceilings
- A musty smell or visible mould in one area
- The sound of running water when every tap is off
- A water meter that keeps spinning with everything shut
- Warm patches on the floor, a classic sign of a hot water line leaking under the slab
- Dropping water pressure in part of the house
One of these alone doesn’t prove a leak, but two or more usually do. The smart move is to confirm it early, while the fix is still small.
Leak Detection in St. Catharines Without Tearing Up Your Property
Guesswork is the expensive way to find a leak. Instead of opening walls at random, we narrow the location down first, then open only what actually needs to be opened.
Our leak detection in St. Catharines uses:
- Acoustic listening equipment that picks up the sound of water escaping a pressurized line, even through concrete
- Thermal imaging to spot temperature changes behind walls, under floors, and in ceilings
- Moisture meters to map how far the water has travelled from the source
- Pressure testing to isolate which section of the system is losing water
- Camera inspection for leaks on drain and sewer lines
The result: a precise repair instead of a demolition project, and a smaller bill at the end.
