Overview

Leak Detection & Repairs

Hidden leaks are sneaky: a slow drip behind a wall or under a slab can run for months, spiking your water bill and rotting timber, plaster and flooring before you ever see a drop. The longer it runs, the more it costs to put right.

JGH Plumbing locates leaks precisely rather than tearing your home open on a hunch. We follow the evidence — water-bill spikes, damp patches, mould, warm spots on floors — pinpoint the source, and carry out the repair. Catching a hidden leak early is dramatically cheaper than repairing the water damage it causes, which is why a quick call at the first sign pays for itself.

FAQs

Leak Detection & Repairs — your questions answered

How do you find a leak you can't see?
We work from the evidence — water-meter readings, damp patches, mould, warm spots and pressure changes — to narrow down the location, then pinpoint the exact source. The goal is to find it precisely so the repair is targeted, rather than opening up walls and floors on a guess.
My water bill suddenly went up — could it be a leak?
Very likely. An unexplained jump in usage almost always means water is escaping somewhere — a running toilet, a leaking pipe, or a hidden underground leak. We can investigate and tell you where it's going, then fix it.
Will you have to cut open my walls or floors?
We aim to avoid unnecessary damage by locating the leak precisely before any access work. Sometimes a small, targeted opening is needed to reach the repair, but pinpointing the source first means we keep that to a minimum.
Is a small leak really worth fixing straight away?
Yes. A slow leak does most of its damage out of sight — rotting timber, ruining plaster, feeding mould — and it keeps adding to your water bill the whole time. Catching it early is far cheaper than repairing the damage it causes later.
Can you fix a burst pipe in an emergency?
Yes. A burst or split pipe is an emergency and we treat it as one — call us 24/7. The first thing to do is turn the water off at the meter to stop the damage, then call us and we'll get there as fast as we can.
Do you repair the leak or just locate it?
Both. We find the source and carry out the repair, so you're not left with a diagnosis and a separate job to organise. The repair is backed by our lifetime workmanship warranty.
