Every PrimeFix engineer holds NVQ Level 2/3 qualifications, Gas Safe registration, and NICEIC approval where relevant. The company itself is CHAS accredited and SafeContractor approved.
As our home base, Borehamwood gets our quickest response times. Our engineers use thermal imaging, acoustic surveys, and tracer gas testing to trace hidden leaks accurately. No unnecessary drilling or digging.
By the time you notice a rising water bill, a damp patch that won’t dry out, or showers growing weaker by the day, water damage may be spreading through your home.
Using thermal imaging, acoustic listening equipment, and tracer gas, our engineers locate the exact source with minimal disruption to your property. Once we’ve confirmed where the leak is, we’ll walk you through the findings, recommend next steps, and provide documentation for an insurance claim where needed.
Every quote is confirmed in writing before any work starts. No call-out fee, no parking charges, and no surprises on the invoice.
We back our work with an 18-month workmanship guarantee.
Every water leak detection job follows the same process: starting broader and narrowing the search for the leak as you get closer.
We don’t guess, and we don’t open anything up until we’re certain we’ve found the source of the leak. Here’s the equipment behind every investigation.
When a boiler or system keeps losing pressure with nothing visibly wrong, that's often the first clue. We isolate the circuit, bring it up to a controlled test pressure, and narrow down the fault area, usually within the hour.
Water moving behind a wall or under a floor changes the surface temperature just enough for an infrared camera to detect it. No tiles lifted, no plaster opened. The camera searches first, so we don't have to.
A soft patch of floor, a stain that keeps coming back, a ceiling mark with no roof leak to explain it: moisture readings tell us how far the water has spread and point us toward the source.
Escaping water under pressure has its own sound signature. Our ground mics and pipe-correlation equipment can pick it up even underground or behind finished walls.
For leaks that won't reveal themselves 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's our most precise method, reserved for the hardest cases.

Straight answers to the questions we're asked most. If yours isn't here, call 020 8108 0400 and we'll talk you through it.
We charge by the hour: £120 +VAT for the first hour, then £60 +VAT per half hour after that. There’s no call-out fee, and you’ll get a confirmed price before any work begins. Parking, ULEZ, congestion charge, and fuel surcharges are never added on top.
Plan for one to two hours in most cases. The exact time depends on your property’s size and pipework layout. We’ll confirm a realistic window when you book.
In the vast majority of cases, no. Between thermal imaging, acoustic tracing, moisture mapping, and tracer gas, we narrow the source down long before any opening-up is considered. Most jobs finish without a single tile or panel disturbed.
Yes, every time. You’ll receive a full digital report detailing where the leak was, which methods confirmed it, and what we found. This is the standard format major UK insurers expect for trace and access claims.
Either works. Our emergency line runs 24/7, 365 days a year, with no extra charge for out-of-hours callouts. For anything non-urgent, we’ll simply book a time that fits your schedule.
