Telltale signs: leak detection
Hidden leaks give themselves away slowly. A water bill that climbs without explanation, a meter that keeps moving when every tap is off, a warm patch on a basement slab, a musty smell in a closet or brown rings on a ceiling under a bathroom all deserve attention. So does the sound of running water in a quiet house.
Why Vaughan houses see it
Copper in homes from the 1970s and 1980s can develop pinholes over time, particularly on hot water lines. In newer builds, a crimp fitting on PEX tucked inside a finished basement ceiling can weep for months before anyone notices. Shower valves and tub drains set in tile walls, toilet wax seals, and supply lines to fridges and dishwashers are frequent culprits across every Vaughan neighbourhood.
The work, stage by stage
- Confirm a leak exists. With fixtures off, we watch the water meter and may pressure-test sections of the supply piping.
- Narrow it down. Fixtures are isolated one at a time to separate supply leaks from drain leaks.
- Locate. Moisture meters, thermal imaging and acoustic listening equipment help us pinpoint where water is escaping inside walls, floors or ceilings.
- Open small. We mark the spot and cut the smallest practical access opening.
- Report. You see what failed and hear the repair options before work continues.
A drip into a ceiling is often from a drain or a shower surround, not a pressurised pipe. Running the shower for ten minutes and watching the ceiling below is a useful first test.
What moves the price
Leaks on pressurised lines are usually quicker to find than slow drain leaks that only show up when a fixture is in use. Slab leaks under a basement floor take more equipment and care. The finishes involved also matter: drywall is simple to patch, while tile, hardwood and cabinetry take more planning. We will tell you plainly whether a finish trade will be needed afterwards.
Before the van pulls up
Read your water meter, wait an hour with no water used, and read it again. Write both numbers down. Photograph any stains and note when they appear: after showers, after laundry, or all the time. If a stain is spreading fast, shut the main valve. When a pipe has failed outright, our burst pipe repair page explains the next steps, and leaks behind tile sometimes lead naturally into bathroom plumbing renovation. We trace leaks in Velmar and right across Vaughan.
Why speed matters
Even a slow leak feeds mould in drywall and insulation within days, and wood subfloors soften when they stay damp. The repair itself is often modest. The damage that follows a leak left alone for a season is not. Calling as soon as the meter test looks wrong is the cheapest decision you can make.
What we open up on this job
| Part | Where we find it | What we do |
|---|---|---|
| Copper type M | Most 1960s–1990s homes | Cut out pinholes, sweat or press new fittings |
| PEX | Newer subdivisions and renovations | Crimp or expansion fittings, manifold checks |
| Poly-B or Kitec | Some 1980s–2000s builds | Identify, then plan a replacement |
| Galvanized steel | Older village houses | Replace runs as they choke with scale |

Quick answers
Can a leak be traced without cutting into walls?
Frequently we pin it down so precisely that a small opening does the job to repair it. Some leaks can be confirmed without any opening at all.
Will my insurance cover leak detection?
That depends on the policy. Call your insurer early and keep our report and photos for the claim.
Is a slab leak common in Vaughan?
It is less common than wall and ceiling leaks, but it does occur, mostly with older copper laid under basement floors.
