Non-invasive detection of slab leaks, hidden pipes, and underground lines.
A leak you can see isn't the dangerous kind. The dangerous kind is the one moving silently behind drywall, under a concrete slab, or beneath your front yard for weeks before anyone notices. By the time the water bill spikes — or the warm spot appears on the floor, or the mystery musty smell shows up in a closet — the damage already extends well beyond the leak itself.
Elite Plumbing Services operates as a specialist leak detection company in Markham. That distinction matters. Most plumbing companies will respond to a leak; very few are equipped to find one that isn't yet visible. Our detection work is built on acoustic equipment, thermal imaging, pressure differential analysis, and tracer gas — not guessing where to start cutting drywall.
Different leaks behave differently. The detection method has to match the leak type, the building material, and the access conditions on-site.
We use electronic amplification equipment to listen for pressurized water moving through a leak point under the slab. Spot repair or full reroute options explained in detail.
Thermal imaging, acoustic listening devices, and moisture meters to open exactly the right spot — no exploratory holes.
Pressure testing, ground microphones, and tracer gas for buried lines between meter and house.
Pressure testing per circuit and acoustic location for pools and irrigation systems.
Combustible gas detectors, pressure-decay testing, and utility coordination when needed.
Whole-home systems with automatic shutoff valves and smartphone notifications.
"The detection visit itself costs more than a general service call. The total repair bill — including restoration — almost always ends up lower."
Water saturates area. Subfloors swell. Drywall wicks moisture. Not yet visible.
Mold colonies form. Water bill rises. Flooring may warp or feel warm.
Structural damage. Insurance claims. Expensive remediation.
A homeowner in Markham called us after a third plumber failed to locate the source of a recurring damp spot... Our technician located the leak... The homeowner chose the reroute. Total intervention: one targeted ceiling opening... The repair held, the bill stabilized.
Equipment calibrated on every job. Static pressure tests performed twice. Single targeted openings. Honest recommendations. We explain all options.
"Third plumber I called... Elite walked in, ran their equipment... Single ceiling cut, fixed in one visit."
"They walked me through both options... Reroute held perfectly. Almost a year now."
"Came back same-day, no charge... The fact that they didn't argue about a callback says everything."
Unexplained spike in water bill, warm/damp spots, sound of running water when off, mildew smells, discoloration.
Acoustic equipment for slab, thermal imaging for walls, ground microphones and tracer gas for mains. Non-speculative.
Detection is non-invasive. Only targeted repair opening is made — sized to the actual work needed.
Most appointments within 24-48 hours. Same-day for active damage.
Yes — detection and repair by the same team whenever possible.
Flat diagnostic fee. Repair quoted after location. Detection fee often credited toward repair.
The most expensive leak is the one you suspected but didn't act on... Calling early is dramatically cheaper than calling on time.
If you've noticed signs of a hidden leak in Markham — unexplained bill increases, damp spots, warm floors — get the source located before the damage compounds.
