Reliable, Non-Destructive Water Leak Detection Across Barnet

Not every leak announces itself. Sometimes it’s an unexplained jump in your water bill, a patch of damp that never fully clears, or taps that seem to have lost their usual pressure.

Instead of opening up walls and floors on a hunch, our engineers use thermal imaging, acoustic listening equipment, and tracer gas to confirm the source before any work begins. From there, we’ll talk you through what’s been found, outline the repair, and prepare insurance documentation if it’s needed.

Precision without the mess

We confirm the leak's exact position before considering any invasive work, so most jobs never require opening a wall at all.

Straightforward pricing

£85 +VAT for the first hour, £42.50 +VAT per half hour after. No call-out fee, no parking charges, nothing added later.

Documentation insurers trust

Every job ends with a full technical report, built to a standard recognised by major insurers for trace and access claims.

The Detection Methods Behind Every Barnet Survey

Every investigation follows the same structured approach: rule things out methodically, then close in on the source.

We never open up a property on a guess. Here’s the equipment that makes that possible.

Water Leak Detection in Barnet

Pressure Test

If a heating system or boiler keeps dropping pressure with no visible cause, that's usually the first indicator. We isolate the circuit, build it back up to a controlled test pressure, and narrow the fault down, typically within the hour.

Thermal imaging water leak detection

Thermal Imaging

A leak travelling behind a wall or beneath a floor creates a subtle temperature shift, exactly what an infrared camera is built to catch. Nothing needs lifting or opening. The camera scans first, before any tools come out.

Moisture Readings

A ceiling stain with no roof leak nearby, a floor that's gone soft, marks that won't stop reappearing: moisture readings map how far water has spread and which direction it's coming from.

Acoustic Tracing

Pressurised water escaping through a pipe produces a sound signature all its own. With ground mics and pipe-correlation equipment, we can pick it up even beneath concrete or behind sealed walls.

Gas Trace

For the leaks that stay hidden from everything else, we introduce a safe hydrogen-nitrogen mix and follow it using sensitive detection equipment until we find the exact escape point. It's our most accurate method, kept in reserve for the hardest cases.
