Leak Detection

We find leaks without wrecking your floors

Non-invasive leak location for coastal and remote WA homes — we find slab leaks, failing mains and pressure faults without tearing up your floors on a hunch.

Leak Detection We find leaks without wrecking your floors

A slab leak can weep for months before you ever see a mark, while your water bill quietly climbs. Finding it without tearing up the house is the whole job. North Contracting uses acoustic and pressure-based location to pinpoint the source first, so we open one spot instead of the whole floor. Kim has traced leaks across coastal homes, holiday rentals and remote WA properties for over twenty years. We follow the water to where it is, fix it properly, and lodge the WA paperwork.

“We open up one spot, not the whole floor.”

01

Find the leak before you break the floor

Guesswork is expensive. Jackhammering a slab to chase a sound you half-heard costs you money and leaves you with a repair on top of a repair. We locate first. Using acoustic listening gear, pressure testing and thermal clues, we narrow a hidden leak down to a single point before anything gets opened. That means one targeted access hole, not a trench across your living room. On coastal homes with tiled floors and slab-on-ground construction, that difference is the whole job. You get a clear answer on where the water is and what it will take to fix it.

02

Slab leaks and water main faults

The leaks that do the real damage are the ones you cannot see. A pipe failing under the slab, a water main weeping somewhere between the meter and the house, a joint that has given up beneath a paved driveway. Salt-laden air and shifting sand soils are hard on buried pipework along the Turquoise Coast, and old galvanised mains corrode from the inside out. We trace the line, confirm the fault, and tell you plainly whether it is a spot repair or a section that needs replacing — no upselling, no surprises when the quote lands.

03

When the water bill climbs and nothing looks wrong

A bill that jumps with no change in how you live is usually water escaping where you cannot see it. Before we dig or drill, we isolate the system and test it methodically — meter readings, pressure holds, fixture checks — to confirm there genuinely is a leak and roughly where it sits. Sometimes it is a running toilet or a garden line; sometimes it is under the slab. Either way you get a straight diagnosis rather than a shrug. For holiday rentals where nobody is on site between guests, catching a silent leak early saves a flooded return.

04

Bore, pump and pressure systems

Plenty of coastal and rural WA blocks run on bore water, rainwater tanks and pressure pumps rather than mains alone. These systems fail differently — a pump that short-cycles, pressure that drops overnight, a foot valve or fitting letting go underground. We know how these setups are plumbed on self-sufficient properties and how to test them without guessing. If your pump keeps kicking in when no tap is open, something is leaking on the pressure side, and we will find it. Off-grid and remote setups are our normal, not an exception we send someone else out for.

05

One licensed plumber, start to finish

The plumber who inspects your leak is the one who does the repair — Kim, licensed and accountable, not a subcontractor you have never met. That continuity matters on leak work: the person who heard the pipe and read the pressure is the same person deciding how to open it up. Every job is done to WA standards with the compliance paperwork lodged, so if you ever sell or insure the property, the record is clean. Clear upfront quote, honest scope, proper fix.

Questions

Good to know.

Can you find a leak without digging up my floor?
Yes. That is the point of proper leak detection. We use acoustic listening equipment, pressure testing and thermal clues to pinpoint the source before anything is opened. In most cases that means a single targeted access point rather than tearing up a whole floor or trenching the yard. We only open up once we know where the water actually is.
My water bill jumped but I can't see any leak. What now?
A bill that climbs with no change in usage almost always means water escaping out of sight — under a slab, along a buried main, or a fixture running quietly. We isolate the system and test it methodically to confirm the leak exists and locate it. Silent leaks are common on porous coastal blocks where water drains away without leaving a visible mark.
Do you work on bore water and pressure pump systems?
Yes. Many coastal and remote WA properties run on bore water, rainwater tanks and pressure pumps, and these fail differently to mains supply. If your pump short-cycles or pressure drops overnight, something is leaking on the pressure side. We know how self-sufficient and off-grid setups are plumbed and test them without guesswork.
How far will you travel for leak detection?
We service Perth's northern suburbs, Lancelin, Nilgen, Jurien Bay and the Turquoise Coast, plus the Pilbara and regional WA subject to availability. Remote and coastal work is our normal — Kim spent six years based in Newman working across the mines and remote communities. Call 0412 448 545 to check availability for your area.
Will the repair be compliant if I sell or insure the property?
Yes. Every job is completed to WA standards with the proper compliance paperwork lodged. That keeps your records clean for insurance and future sale, and it means the fix is done correctly rather than patched. You deal with a licensed plumber and gas fitter throughout — Plumbing Licence PL10419.
