Real Engineers. Real Skills. Real Accreditation. Based just minutes from Cockfosters.
Cockfosters sits well within our coverage area, around 20 minutes from our Borehamwood base, and we visit regularly. Our engineers bring thermal imaging, acoustic survey tools, and tracer gas to every job, confirming exactly where a leak is before any floor or wall is touched.
A leak doesn’t always announce itself straight away. It might be a water bill that’s climbed for no clear reason, a damp patch on a wall that never quite dries, or a boiler that keeps losing pressure. All of these point to the same thing: water escaping somewhere it shouldn’t be.
We don’t start with assumptions. Thermal imaging, acoustic listening equipment, and tracer gas let our engineers confirm exactly where a leak is before any repair is even discussed. Once we’ve found the source, we’ll explain what it means, recommend the right fix, and put together insurance documentation if it’s needed.

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

Your quote is confirmed in writing before any work starts, no call-out fee, no parking costs, nothing added on afterwards.
Every job comes with our 18-month workmanship guarantee.
We work through a fixed process on every job: rule out the obvious first, then confirm the exact source.
Nothing is opened up until we’re certain. Here’s the equipment that makes that possible.

A boiler or heating system that loses pressure with no clear cause is often the first sign of a leak. We isolate the circuit, build it back up to a controlled test pressure, and narrow the fault down, usually within an hour.

Water travelling behind a wall or under a floor creates a small temperature difference that an infrared camera can detect straight away. Nothing gets opened until the camera has pointed us in the right direction.

A floor that's gone soft, damp reappearing in the same place, a ceiling stain with no roof fault to explain it: moisture readings show how far the water's spread and which way it's travelling.

Pressurised water escaping through a pipe makes a sound of its own. Ground microphones and pipe-correlation equipment let us detect it even beneath concrete or hidden behind finished walls.

For leaks other methods can't find, we introduce a safe hydrogen-nitrogen mix into the system and track it with sensitive detectors until we locate the exact point of escape. It's the most precise method we use, reserved for the hardest cases.
Every quote is confirmed in writing before work starts. No call-out fee. No hidden charges.
