What this job involves
Concealed leaks speak in hints: a quarterly bill that jumps, a tea-coloured blotch on drywall, one warm patch in a slab floor, a damp-cardboard smell in a vanity. Finding the source without gutting walls is a process of elimination. We begin at the meter to confirm water is actually moving, then isolate branches of the system until the search narrows to a single room or run.
How the job goes
- Watch the meter’s low-flow dial with every fixture shut.
- Close toilet stops and appliance valves one at a time to rule them out.
- Sweep walls and ceilings with a moisture meter.
- Listen along pipe runs for the hiss or tick of escaping water.
- Open the smallest hole that will confirm and fix it.
Warning signs on your pipes
- The Halton bill climbed though your habits did not.
- The meter dial creeps with all taps closed.
- A ceiling stain spreads under a bathroom.
- One patch of floor feels oddly warm.
- Mildew or mustiness inside a closet.
From the job notes
Toilets head the list of hidden leaks we find, followed by the supply lines to fridges, dishwashers and washers.
Toilets head the list of hidden leaks we find, followed by the supply lines to fridges, dishwashers and washers. A leak inside a slab or behind a finished basement wall takes longer, but the meter check always comes first.
Ceiling stains mislead. Water travels along joists before it drips, so the blotch may sit a metre or more from the source. We trace back from the stain rather than straight up.
What comes off the truck
| Tool or part | What it does on the job |
|---|---|
| Screw-on test gauge | Threads onto an outside tap so we log line pressure ahead of and after any valve work |
| Tube cutter and deburring tool | Clean square cuts on copper before a joint is made |
Questions we hear
Can you pinpoint it without demolition?
Usually we narrow it to a small area. A modest opening may still be needed for the repair itself.
Does insurance pay for leak finding?
Policies differ. Ask your insurer about access and repair coverage.
