Yes — every engineer holds relevant qualifications (NVQ Level 2/3, Gas Safe registration, NICEIC approval where the job calls for it), and PrimeFix itself is CHAS accredited and SafeContractor approved.
Using thermal imaging, acoustic surveys, and tracer gas testing, our specialists pinpoint hidden leaks fast — without unnecessary damage to your property.
Most leaks don’t start with a flood. They often show up as a higher water bill, damp patches, or a boiler that keeps losing pressure. By the time water is visible, it may already have caused hidden damage.
That’s why we use specialist detection equipment first. Thermal imaging, acoustic technology, and tracer gas help pinpoint leaks with minimal disruption. Once the source is confirmed, we explain the problem, recommend the repair, and can provide a report for insurance claims if needed.
Every job follows the same process, in the same order. We don’t guess, and we don’t open anything up until we’re certain. Here’s the equipment behind every investigation.
A boiler or system that keeps losing pressure with nothing visibly wrong is often the first clue. We isolate the circuit, bring it up to a controlled test pressure, and narrow down the fault area — usually inside the hour.
Water moving behind a wall or under a floor changes the surface temperature just enough for an infrared camera to pick it up. No tiles lifted, no plaster opened. The camera does the searching first.
A soft patch of floor, a stain that keeps returning, a ceiling mark with no roof leak to explain it. Moisture readings tell us how far it's spread and point us toward the source.
Escaping water under pressure has its own sound signature. Ground mics and pipe-correlation equipment pick it up, even underground or behind finished walls.
For the leaks that won't show up any other way, a safe hydrogen-nitrogen mix is fed into the system and followed with sensitive detectors until it reaches the exact point of escape. It'sour most precise method, reserved for the hardest cases.

Common questions about water leak detection, answered plainly. If you don't see what you're looking for, call us on 02081080400 and we'll talk you through it.
Our leak detection call-outs are charged hourly — £120 +VAT covers the first hour, then £60 +VAT for each half-hour after that. There’s no call-out fee, and you’ll get a confirmed price before anyone picks up a tool. Parking, ULEZ, congestion charge and fuel surcharges are never added on top.
Most surveys wrap up in one to two hours, though it depends on the property size and how the pipework’s laid out. We’ll give you a realistic estimate at the time of booking, not after we’ve arrived.
Almost never. Thermal imaging, acoustic tracing, moisture mapping and tracer gas let us narrow down the source before any opening-up work is even considered. Most jobs are resolved without touching a single tile or panel.
Always. Every survey ends with a full digital report covering the leak source, the methods we used to find it, and our findings — written to a standard accepted by every major UK insurer handling trace and access claims.
Both. We run a 24/7 emergency line, 365 days a year, with no out-of-hours surcharge. If it’s not urgent, we’re just as happy to book a slot that suits your schedule.
