Experienced, accredited engineers, based just around the corner.
Potters Bar is one of our regular coverage areas, roughly 15 minutes from our Borehamwood base. Our engineers arrive with thermal imaging, acoustic survey tools, and tracer gas, so the leak’s source is confirmed before any work touches a floor or wall.
Leaks don’t always show themselves clearly. It might be a water bill that’s higher than usual, a stubborn damp patch, or water pressure that’s quietly dropped off.
Rather than guessing and opening things up, we use thermal imaging, acoustic listening equipment, and tracer gas to identify exactly where the problem is first. Once confirmed, we’ll explain the findings, recommend a repair, and provide documentation for your insurer if you need it.
You’ll get a written quote before we start any work, with no call-out fee, no parking costs, and no extras added afterwards.
Every job carries our 18-month workmanship guarantee.
Our process is the same for every job: check systematically, eliminate the unlikely, and zero in on the source.
We don’t open anything up until we know for certain. Here’s the equipment we rely on to get there.
Unexplained pressure loss in a boiler or heating system is often the earliest warning sign. We isolate the circuit, restore it to a controlled test pressure, and narrow the fault area, usually inside an hour.
A leak moving under a floor or behind a wall causes a small but detectable temperature change, which is exactly what an infrared camera picks up. Nothing needs to be lifted or opened first; the camera leads the search.
Recurring marks, a floor gone soft in one spot, a ceiling stain with no roof issue behind it: moisture readings tell us how far the water's spread and which way to trace it.
Water under pressure escaping through a pipe creates a distinctive sound. Ground mics and pipe-correlation equipment can detect it even below concrete or behind sealed-up walls.
When other methods can't locate the leak, we use a safe hydrogen-nitrogen mix introduced into the system, tracked with sensitive detectors until we reach the exact point of escape. It's our most precise method, saved for the most difficult cases.

It’s charged hourly: £85 +VAT for the first hour, then £42.50 +VAT per half hour after. We confirm the price before starting, with no call-out fee and nothing added for parking, ULEZ, or congestion charges.
Typically one to two hours, depending on the property’s layout and how the pipework runs. You’ll get an accurate estimate when you book, not a surprise once we’ve arrived.
Almost never. Between thermal imaging, acoustic tracing, moisture mapping, and tracer gas, we can usually pinpoint the source without opening up any part of the property.
Yes, always. A full digital report is produced for every job, covering the leak location, the detection methods used, and our findings, in a format major UK insurers accept for trace and access claims.
We offer both. Our emergency line is staffed 24/7, 365 days a year, with no out-of-hours surcharge. If it’s not urgent, we’ll simply arrange a time that works for you.
