Experienced, accredited engineers, ready to reach you fast.
Barnet falls well within our regular coverage area, just 15 minutes from our Borehamwood base. Engineers arrive equipped with thermal imaging, acoustic survey tools, and tracer gas to trace a leak’s exact source without opening up floors or walls unnecessarily.
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.
Every quote is confirmed in writing before work starts, with no call-out fee, no parking charges, and nothing extra added to the invoice.
All work comes with our 18-month workmanship guarantee.
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.
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.
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.
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.
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.
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.

We work on an hourly rate: £85 +VAT for the first hour, then £42.50 +VAT per half hour after that. You’ll get a confirmed price before anything starts, with no call-out fee and no added charges for parking, ULEZ, or congestion.
Most surveys finish within one to two hours, depending on the size of the property and how accessible the pipework is. We’ll give you a realistic estimate at the point of booking.
Very rarely. Thermal imaging, acoustic tracing, moisture mapping, and tracer gas usually locate the source without any opening-up at all. Most jobs are completed with nothing disturbed.
Yes, as standard. Every survey produces a full digital report showing where the leak was found, the methods used to confirm it, and our conclusions, formatted to what major UK insurers require for trace and access claims.
Both are possible. Our emergency line operates 24/7, 365 days a year, with no out-of-hours surcharge added. For non-urgent leaks, we’ll book a convenient time instead.
