Water Leak Detection Services in Toronto
A hidden water leak can waste thousands of litres a month, push up your water bill and rot drywall, subfloors and framing long before you see a stain. POM Plumbing provides professional leak detection and leak repair across Toronto and the GTA. Our licensed plumbers use non-invasive water leak detection equipment to pinpoint the exact source behind walls, under floors, in ceilings and below concrete slabs, so we open only what needs to be opened and fix the leak on the same visit whenever possible.
We find and repair leaks in houses, condos, townhomes and commercial buildings, from a slow drip under a vanity to a pressurised supply line leaking inside a ceiling. If water is coming through right now, close your main valve and call our 24/7 emergency plumbers at (905) 625-8777.
Types of Leaks We Find and Fix

Fixture & Appliance Leaks
Toilets, tubs, showers, dishwashers, fridge lines and washing machine hoses. See faucet and toilet repair.

Water Heater Leaks
Relief valves, fittings and tanks that leak slowly into the floor drain. See water heater repair.

Leaks from the suite above, risers or fan coils, traced to the source with a report for management and insurers.
Non-Invasive Leak Detection Methods We Use
We combine several tools to find the leak precisely, then confirm it before opening anything.
| Method | What it finds |
|---|---|
| Water meter and pressure test | Confirms a leak and which line it is on |
| Acoustic listening equipment | Pressurised leaks under slabs and behind tile |
| Thermal imaging camera | Hot-water leaks and wet areas inside walls |
| Moisture meters | How far water has spread in drywall and floors |
| Video camera inspection | Cracked or separated drain and sewer pipes |
| Tracer gas and dye testing | Tiny leaks and shower or tub pan leaks |

Call (905) 625-8777Signs You Have a Hidden Water Leak
- Water bill went up without a change in use
- Meter keeps moving with every tap closed
- Stains or bubbling paint on walls and ceilings
- Musty smell or mould in cabinets or the basement
- Warm spots on the floor from a hot-water slab leak
- Sound of running water when nothing is on
Common Causes of Water Leaks
- Corroded copper or galvanized pipes in older Toronto homes
- Failing Kitec or Poly-B fittings
- High water pressure stressing joints and fixtures
- Loose or worn supply lines on toilets, sinks and appliances
- Pipes that froze and cracked during a cold snap
- Failed shower pans, tub drains and grout
- Settling foundations and shifting slabs
- Tree roots and cracked drain lines outside
How to Check for a Hidden Leak Yourself
You can confirm most hidden leaks yourself in a few minutes before you call.
- Water meter test. Turn off every tap and appliance, note the meter reading or leak indicator, wait 30 minutes without using water and check again.
- Toilet dye test. Put a few drops of food colouring in the tank. If colour appears in the bowl within 15 minutes, the flapper is leaking.
- Check the water heater. Look for water at the base, the relief valve pipe and fittings on top.
- Look under sinks and appliances. Check supply lines, shut-offs and the floor behind the dishwasher and washer.
- Call us if the meter moved. The leak is likely hidden and needs professional detection.
How Much Water Does a Leak Waste?
| Leak | Approx. water lost |
|---|---|
| Dripping faucet (1 drip per second) | about 11,000 litres a year |
| Running toilet | up to 750 litres a day |
| 3 mm crack in a supply pipe | hundreds of litres a day |
| Burst supply line | over 1,000 litres an hour |

Leak Detection Process and Cost
From the first call to the final report, here is what to expect and what it typically costs.
How Our Leak Detection Service Works
- Call and describe the symptoms. We ask about stains, sounds and your water bill so the plumber arrives with the right equipment.
- Confirm the leak. Meter and pressure tests show whether water is escaping and from which line.
- Pinpoint the source. Acoustic, thermal and moisture tools locate the leak without tearing out walls.
- Repair the leak. We open a small access point, replace the damaged fitting or section and pressure-test the line.
- Report for insurance. You get photos, readings and a written cause-of-leak summary for your insurer or property manager.
Leak Detection & Repair Cost in Toronto
Every home is different, so we confirm the price before any work begins. Typical ranges before tax:
| Service | Typical cost |
|---|---|
| Leak detection visit (one area) | $250 – $450 |
| Full-home leak detection with report | $450 – $750 |
| Accessible pipe or fixture leak repair | $200 – $450 |
| Leak inside a wall or ceiling | $450 – $1,000+ |
| Slab leak repair or reroute | quoted after detection |
How Long Does It Take?
Most leak detection visits take 1 to 3 hours. Simple fixture and pipe repairs are usually done on the same visit, while slab leaks and leaks that need a reroute are scheduled after we confirm the best repair. Drywall patching and painting are done after the line has been tested and dried.
Slab Leak Repair
When a supply line leaks under a basement floor, we locate it to within a few centimetres and either repair it through a small opening in the concrete or reroute the line through walls or ceilings, whichever causes less disruption and lasts longer. Rerouting is often the better choice in older homes where more leaks are likely.

Leak Detection Tips for Toronto Homeowners
Check your water meter twice a year, replace rubber washing machine hoses every five years, know where your main shut-off is, and consider a smart leak detector or automatic shut-off valve near the water heater and laundry. If your home has Kitec, Poly-B or original galvanized pipes, a plumbing inspection can catch failing fittings before they leak.

Leak Detection FAQ
-
How do you find a water leak without opening walls?
We use non-invasive water leak detection tools: acoustic sensors, thermal imaging cameras, moisture meters, pressure testing and tracer gas. Together they narrow the leak down to a small area, so only a small access hole is needed for the repair.
-
How much does leak detection cost in Toronto?
A leak detection visit for one area typically costs $250 to $450, and a full-home detection with a report $450 to $750. Repair costs depend on where the pipe is and how much needs to be opened. We confirm the price before work starts.
-
How can I tell if I have a hidden leak?
Turn off every tap and water-using appliance and watch your water meter for 30 minutes. If it moves, water is escaping somewhere. Higher bills, stains, musty smells and the sound of running water are other common signs.
-
Do you repair the leak on the same visit?
In most cases, yes. Once the leak is located, our plumbers repair the damaged pipe or fitting right away and pressure-test the line before leaving.
-
How long does leak detection take?
Most visits take 1 to 3 hours depending on the size of the home and how many lines need testing.
-
What is a slab leak and how is it repaired?
A slab leak is a leak in a water line running under a concrete floor. We locate it precisely, then either repair it through a small opening in the slab or reroute the line above the floor.
-
Will my insurance cover leak detection?
Many home insurance policies cover the cost of finding a sudden leak and the resulting water damage, though not always the pipe repair. We provide photos, readings and a written report you can submit with your claim.
-
Can a small leak really cause serious damage?
Yes. A slow leak inside a wall can rot framing, damage subfloors and grow mould for months before it shows. Finding it early is far cheaper than repairing the damage later.
-
What is the difference between a leak and a burst pipe?
A leak is a slow loss of water from a joint, fitting or small crack. A burst pipe is a sudden failure that releases a large amount of water and needs emergency service.
-
Do you find leaks in condos and commercial buildings?
Yes. We trace suite-to-suite leaks, riser and fan-coil leaks in condos and leaks in offices, stores and restaurants, and we provide reports for property managers.
-
Can I fix a leak myself?
Simple fixes like tightening a supply line or replacing a toilet flapper are often DIY. Hidden leaks, slab leaks and leaks in walls need professional detection and repair.
-
Do you offer emergency leak repair at night?
Yes. Our plumbers are available 24/7 across Toronto and the GTA. Shut off the main water valve and call (905) 625-8777.
