Not every leak announces itself with a dripping faucet. Many of the costliest leaks are hidden — behind walls, under slabs, beneath floors, or underground in the water service line. Warning signs include an unexplained jump in your water bill, damp or discoloured patches on walls and ceilings, a musty smell, warm spots on the floor, or the sound of running water when everything is off. Left unchecked, these leaks feed mould growth and structural damage that costs far more than the original repair.
Our plumbers use non-invasive detection tools — acoustic listening equipment, moisture meters, thermal imaging and pressure testing — to pinpoint the exact location of a leak without tearing open walls and floors unnecessarily. This targeted approach means we open only what we need to, keeping the repair cleaner, faster and less expensive for you.
Once located, we repair the source properly, whether it is a corroded pipe joint, a pinhole leak in copper, a failed fitting, or a cracked supply line. In older North York neighbourhoods with aging plumbing, small pinhole leaks are common and tend to multiply — we can advise whether a spot repair or a section of repiping is the wiser long-term choice.
Slab and underground leaks require special care, and our team is experienced in locating and repairing them with minimal disruption to your property. We also check for leaks that may be affecting only part of your system, so one visit resolves the full problem rather than leaving hidden issues behind.
Every leak detection and repair job includes upfront pricing and a clear explanation of what we found. Catching a leak early is one of the best ways to protect your North York home's value — and if you suspect one right now, we offer prompt and 24/7 emergency service to stop the damage fast.

Frequently Asked Questions
How do I know if I have a hidden leak?
Common signs include a rising water bill, damp or stained walls and ceilings, musty odours, warm floor spots, or the sound of running water when nothing is on. If you notice these, call us for a professional inspection.
Do you have to break walls to find a leak?
Not usually. We use non-invasive tools like acoustic sensors, moisture meters and thermal imaging to pinpoint the leak first, so we open only the exact area that needs repair.
Can a small leak really cause big damage?
Yes. Even a slow, hidden leak can feed mould growth and rot structural wood over time, leading to repairs far more costly than fixing the leak early.
Is leak detection available for emergencies?
Yes. If you have active water damage or a sudden pressure drop, we provide 24/7 emergency leak detection and repair across North York.
