Fully qualified engineers, on your doorstep within minutes.
Radlett sits just minutes from our Borehamwood depot, so engineers can usually be with you the same day. We use thermal imaging, acoustic surveys, and tracer gas to find the exact source of a leak before any floor or wall is touched.
A water leak isn’t always obvious and may present itself as a rising water bill, a damp patch that won’t dry out, or a shower slowly losing pressure.
Rather than break into walls or floors to search, we bring thermal imaging, acoustic listening equipment, and tracer gas to pinpoint the source first. Once we know exactly where the leak is, we’ll explain what we’ve found, advise on repair, and put together insurance documentation if you need it.

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

You’ll receive a written quote before any work begins. No call-out fee, no parking charges, no surprises on the invoice.
Every job is backed by our 18-month workmanship guarantee.
We follow the same disciplined process on every job, working from broad checks down to a precise fix on the leak.
Nothing gets opened up until we’re certain we’ve found it. Here’s the kit we use to get there.

A boiler or heating system that keeps losing pressure, with no obvious fault, is often the first sign something's wrong. We isolate the circuit, bring it up to a controlled test pressure, and narrow the fault area down, usually inside an hour.

A leak moving behind a wall or under a floor shifts the surface temperature just enough for an infrared camera to catch it. Nothing gets lifted or opened. The camera does the first pass so we don't have to.

Recurring stains, a soft patch underfoot, a ceiling mark with no roof leak in sight: moisture readings show us how far the water's travelled and which direction to search.

Water escaping under pressure gives off a distinct sound. Ground mics and pipe-correlation kit can detect it even underground or sealed behind finished walls.

When nothing else reveals the leak, we introduce a safe hydrogen-nitrogen mix into the system and track it with sensitive detectors until we reach the exact escape point. It's the most precise method we have, kept for the toughest cases.
Every quote is confirmed in writing before work starts. No call-out fee. No hidden charges.
Charged in 30-minute increments 1h after arrival. No call-out fee. £120 +VAT for the first hour.
