Experienced, accredited engineers, ready to reach you fast.
Barnet falls well within our regular coverage area, just 15 minutes from our Borehamwood base. Engineers arrive equipped with thermal imaging, acoustic survey tools, and tracer gas to trace a leak’s exact source without opening up floors or walls unnecessarily.
Not every leak announces itself. Sometimes it’s an unexplained jump in your water bill, a patch of damp that never fully clears, or taps that seem to have lost their usual pressure.
Instead of opening up walls and floors on a hunch, our engineers use thermal imaging, acoustic listening equipment, and tracer gas to confirm the source before any work begins. From there, we’ll talk you through what’s been found, outline the repair, and prepare insurance documentation if it’s needed.

Hi Mohammad , We really appreciate your feedback. And we’re delighted you’re happy with the service provided.Posted on Google M NTrustindex verifies that the original source of the review is Google. Never in my life have I come across a company this professional 👌🏻They explained everything clearly from the start and found and fixed the leak under my shower tray without breaking a single tile. They even put the shower tray and screen back perfectly like nothing had ever happened. Another company quoted me more than double the price, but these guys charged £727 and did an amazing job. Both engineers were amazing.Definitely the best around. Highly recommend.

Hi Andreea, Thank you for your kind words! We’re delighted you had a great experience.Posted on Google Betty CawelyTrustindex verifies that the original source of the review is Google. Aleks from PrimeFix found my leak in an area I would never have expected. It took some time and wasn’t a cheap job, but it was a very difficult leak to find. He worked carefully and managed to locate it with minimal damage. Big thanks to Aleks and the PrimeFix team for their hard work and professionalism. Highly recommended.

Hi Matt , Thank you and we really appreciate the feedback. Gland we would help and of course we’re always here if you need any further support in the future 🙏🏻Posted on Google Kirsty BrownTrustindex verifies that the original source of the review is Google. ⭐️⭐️⭐️⭐️⭐️ We had an underground leak at my 88-year-old mother’s property and contacted Prime Fix Group Ltd. The engineer arrived promptly and, after carrying out an assessment, called me directly to explain the issue, the required work, and all costs involved, as he did not want to stress my mother with the situation. Very professional service from start to finish with no hidden fees at all. Everything was explained clearly before any work was carried out. We submitted the report to our insurance company, who recognised Prime Fix as highly qualified engineers. Highly recommended.

Every quote is confirmed in writing before work starts, with no call-out fee, no parking charges, and nothing extra added to the invoice.
All work comes with our 18-month workmanship guarantee.
Every investigation follows the same structured approach: rule things out methodically, then close in on the source.
We never open up a property on a guess. Here’s the equipment that makes that possible.

If a heating system or boiler keeps dropping pressure with no visible cause, that's usually the first indicator. We isolate the circuit, build it back up to a controlled test pressure, and narrow the fault down, typically within the hour.

A leak travelling behind a wall or beneath a floor creates a subtle temperature shift, exactly what an infrared camera is built to catch. Nothing needs lifting or opening. The camera scans first, before any tools come out.

A ceiling stain with no roof leak nearby, a floor that's gone soft, marks that won't stop reappearing: moisture readings map how far water has spread and which direction it's coming from.

Pressurised water escaping through a pipe produces a sound signature all its own. With ground mics and pipe-correlation equipment, we can pick it up even beneath concrete or behind sealed walls.

For the leaks that stay hidden from everything else, we introduce a safe hydrogen-nitrogen mix and follow it using sensitive detection equipment until we find the exact escape point. It's our most accurate method, kept in reserve for the hardest cases.
Every quote is confirmed in writing before work starts. No call-out fee. No hidden charges.
Discounted rates for landlords, HMOs, and managing agents with multiple properties. Dedicated account manager included.
No hidden extras: no parking, fuel, ULEZ, or Congestion Charge surcharges. Materials at trade cost plus 30% markup, fully itemised on the invoice.
Account-client portfolios receive discounted rates from the published prices.
