Hidden Water Leaks Found and Repaired Before They Spread

Some leaks are obvious, like a dripping tap or a puddle under the sink. Others stay hidden inside walls, ceilings and floors for months, quietly damaging drywall, subfloors and finishes and creating the damp conditions mould needs. Northlife Plumbing provides leak detection and repair for homes and businesses across Toronto, from North York condos to detached houses in Scarborough and Etobicoke. We locate the source first, so you're not paying to open walls in the wrong place.

Once we've found the leak, we explain what's causing it and give you an upfront price for the repair before any work starts. Our licensed and insured plumbers fix everything from loose fittings and worn supply lines to corroded sections of pipe, and we clean up when the job is done. For active leaks and burst pipes, we're available 24/7.

Signs You May Have a Hidden Leak

Hidden leaks usually leave small clues before they turn into major damage. If you notice any of these, it's worth having your plumbing checked:

A water bill that rises without explanation
Stains, bubbling paint or soft drywall
Musty odours or visible mould
Warped flooring or loose tiles
Running water sounds when everything is off

Our Approach: Locate, Quote, Repair

We start with simple checks that rule causes in or out, such as watching the water meter with all fixtures off and inspecting visible supply lines, valves and connections. Then we narrow down the location so any opening is as small as possible. You get a clear explanation and price before we repair anything, and we test the line afterwards to confirm it stays dry.

What to Do While You Wait for Us

If water is actively leaking, close the nearest shut-off valve or the main water valve. Keep away from outlets and appliances near the water unless you can switch off their power safely. Move belongings out of the way, catch drips with a bucket or towels, and then call us, day or night.

Our Leak Detection and Repair Services Include:

Hidden Pipe Leaks: We trace leaks inside walls, ceilings and floors and repair the damaged section with as little disruption as possible.

Fixture Leaks: Dripping taps, running toilets and leaking shower valves are repaired so you stop paying for water you never used.

Under-Sink Leaks: Loose connections, worn supply lines and failed drain fittings under kitchen and bathroom sinks are fixed and tested.

Pipe Replacement and Repiping: When older pipes keep developing leaks, we replace the affected sections or repipe for a longer-lasting fix.

Water Line Leaks: We locate and repair leaks on the water line that supplies your home or business.

Frequently Asked Questions

How can I tell if I have a leak when I can't see any water?

Turn off every tap and water-using appliance, then check your water meter. If the reading keeps moving, water is likely escaping somewhere. Other clues include a rising bill, musty smells and stains on walls or ceilings.

Will you have to open my walls to find the leak?

Not always. We work to pinpoint the source before opening anything, and if access is needed, we keep the opening as small as possible. We'll explain exactly what's required before any work starts.

What affects the cost of leak repair?

The location of the leak, how easy it is to reach and the type of pipe involved are the biggest factors. A loose fitting under a sink is a quick fix, while a leak inside a finished wall takes more work. You always get an upfront price to approve first.

Is a small drip really worth fixing?

Yes. Even a slow drip wastes water every day, and leaks usually get worse over time. A hidden leak can also cause rot and mould long before you see it, so fixing it early is usually simpler and less costly.
