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.
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.”
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.
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.
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.
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.
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.
