Hidden Leak Detection Across Galt, Preston and Hespeler

Hy-Pro Plumbing and Drain Cleaning provides water leak detection in Cambridge, locating leaks hidden inside walls, ceilings, basement floors and incoming water lines. We serve homes in Galt, Preston, Hespeler and the newer neighbourhoods between them. Our licensed and insured plumbers average 10 years of experience and use acoustic listening devices and thermal imaging, then confirm each reading visually. For repairs and other plumbing work, our Cambridge plumber team takes calls around the clock.

How Does Hy-Pro Find a Hidden Leak in Cambridge?

We prove the leak on your meter, rule out the usual fixtures, then pinpoint the source with sound and heat readings before anything is opened. You get the location, the cause and a written recommendation. It’s the same method behind Hy-Pro’s plumbing services across Southwestern Ontario.

A leak costs more than most people expect. In 2026, the City of Cambridge charges $2.82 per cubic metre for water and $2.87 for wastewater, so every 1,000 litres a leak wastes adds about $5.69 to your bill. A toilet seeping day and night or a pinhole in a basement line keeps adding to that total until someone finds it.

Our first step is the meter. With every tap, appliance and softener off, we watch the flow indicator. Movement confirms water is escaping somewhere between the meter and your fixtures. Then we close fixture valves one at a time to rule out toilets, the laundry hookups and the fridge line.

When the fixtures check out, the equipment takes over. Acoustic listening devices pick up the hiss of pressurized water escaping through a crack, a loose fitting or a corroded section of pipe, even through concrete. Thermal imaging shows the cooler patch wet drywall or plaster leaves behind. We confirm each finding visually before suggesting where to open.

Some leaks sit under the basement slab. Supply lines that run beneath the floor to a kitchen or laundry room can leak for weeks before you notice damp grout or a warm spot. Our gear narrows a slab leak to a small section of floor, so the concrete work stays as limited as possible.

Housing age in Cambridge shapes the search too. Century homes in Galt and Preston can mix original pipe with decades of patched repairs, while newer subdivisions use PEX lines that leak at fittings rather than along the pipe.

Why Choose Hy-Pro to Locate Leaks in Cambridge

Our plumbers average 10 years of experience, quote before starting and handle emergency calls 24/7 from our Cambridge location. At Hy-Pro, we inspect, show you the evidence and let you choose the repair.

Our paperwork also supports a bill adjustment. Cambridge’s High Water Leak Adjustment Policy requires proof of repair, and the high bill must be issued within the last 90 days. The extra water billed has to be at least twice your average consumption. Our invoices name the leak, the repair and the parts, ready to attach to your application.

The City also limits adjustments to one in any 12 months and two in a 10-year period. That makes an accurate first diagnosis worth more than a quick patch on the wrong pipe.

We’re licensed, insured, Canadian owned and operated. Larger repairs, like replacing a supply line under the slab, are eligible for financing through Financeit, subject to credit approval.

Frequently Asked Questions About Leak Detection in Cambridge

How much does it cost to find a leak in Cambridge?

Time and access drive the cost. A leak traced to one bathroom is a short visit, while a leak under the basement slab or along the buried service line takes more searching. Plaster walls, crawl spaces and after-hours timing also matter. We quote before any work starts. Bring your last few water bills to the visit, since the jump in usage often shows roughly when the leak began.

How do I know if my toilet is leaking silently?

Add a few drops of food colouring to the tank and wait 15 minutes without flushing. Colour in the bowl means the flapper is letting water through. You might also hear the tank refill on its own every so often, a sign it’s losing water to the bowl. Silent toilet leaks rarely leave a puddle, so they show up on the bill before anywhere else. A new flapper fixes many of them, and we handle fill valves and flush valves when it doesn’t.

Can I appeal a high water bill in Cambridge after a leak?

Possibly. The City of Cambridge has an appeal process for bills greater than twice your average consumption and over $250, where no adjustment was granted under the High Water Leak Adjustment Policy. The concern must have happened within the last six months and already gone through the leak adjustment review. Keep your repair invoice and meter photos, since both support your case. Questions go to the City’s Tax and Water Division by email.

What should I do in the first hour after finding a leak?

Close the main shut-off valve, usually beside the water meter in the basement. Open a low faucet to drain pressure from the lines, then move rugs, boxes and electronics away from the wet area. Stay clear of wet outlets and the electrical panel. Photograph the damage and the meter reading, since both help with insurance and any bill adjustment. Then call us, and we’ll take it from there.

What other plumbing services does Hy-Pro offer in Cambridge?

Finding the leak usually leads to the fix. Our Cambridge crews also handle:

  • Slab leak repair for supply lines under basement floors
  • Pipe repair and replacement for pinholed copper and failed fittings
  • Toilet repair for flappers, fill valves and wax rings
  • Water main repairs on the line from the street
  • Water softener service when a valve or drain line sticks

Bring up anything else on your list during the visit, and you’ll have a price before extra work goes ahead.

How do I book a leak detection visit with Hy-Pro in Cambridge?

Call our Cambridge office at 519-622-7770 or request service online, day or night. Tell us what your meter did with everything off and where you’ve noticed damp spots or sounds. If water is still spreading, we’ll guide you through closing the main valve while a plumber is on the way. We also serve Kitchener-Waterloo and Guelph.
