Real Engineers. Real Skills. Based just 20 minutes away.
Watford is one of the largest areas we cover, around 20 minutes from our Borehamwood base, and it’s where we run some of our highest call volumes. Whether it’s a flat, a Victorian terrace, or a commercial unit, our engineers use thermal imaging, acoustic survey tools, and tracer gas to find the exact source of a leak before any floor or wall is touched.
Watford’s mix of housing means leaks show up in different ways depending on the property. A sudden spike in your water bill, a ceiling stain that keeps returning, or a boiler that won’t hold pressure can all point to the same underlying problem: water going somewhere it shouldn’t.
We use thermal imaging, acoustic listening equipment, and tracer gas to confirm exactly where a leak is before any repair work is even discussed. Once the source is identified, we’ll walk you through what we found, explain the recommended fix, and, where it’s useful, prepare documentation your insurer will accept.

Great service! We had a leak in the middle of the night and called Primefix around midnight. The job was booked straight away, and the engineer arrived in less than an hour. Aurel inspected our bathroom, quickly found the source of the leak, and fixed it on the first visit. He saved us a lot of trouble and kept the damage to a minimum. Highly recommended! Primefix will definitely be my go to company from now on.Posted on Google![]()

Losing over 40 litres of water a day. Previous firm sent two Engineers daily, cost thousands, never found the leak. PrimeFix sent one engineer the same day I booked. James was brilliant, found it in a couple of hours and left a detailed written report with photos for insurance. That is the difference between a bill and a result

We’ll confirm your quote in writing before any work begins, no call-out fee, no parking costs, and nothing added on afterwards.
Every job is covered by our 18-month workmanship guarantee.
There’s a set process behind every survey: narrow the possibilities down systematically, then confirm the exact source.
We don’t guess, and we don’t open anything up until we’re sure. Here’s what makes that possible.

When a boiler or heating system loses pressure for no obvious reason, that's often the first clue something's leaking. We isolate the circuit, bring it back up to a controlled test pressure, and narrow down the fault area, usually within the hour.

Water moving behind a wall or beneath a floor produces a slight, detectable change in surface temperature, which an infrared camera picks up immediately. Nothing gets lifted or opened until the camera's confirmed where to look.

A ceiling mark with no roof problem behind it, a section of floor that's gone soft, damp that keeps reappearing in the same spot: moisture readings show us how far it's spread and which direction leads back to the source.

Water escaping under pressure has a sound signature of its own. With ground microphones and pipe-correlation equipment, we can detect it even underground or hidden behind finished walls.

Where other methods can't locate a leak, we introduce a safe hydrogen-nitrogen mix into the system and track it using sensitive detectors until we reach the exact point of escape. It's the most precise method available to us, kept for the hardest-to-find leaks.
