How do I know if I have a leak if I can’t see it?

It’s hard to miss water dripping from your ceiling or an unexpected new water feature springing up from the middle of your garden, but how do you know if you have a water leak if the symptoms are not so obvious?

Here’s a few quick and simple things to keep an eye on that could suggest you need the help of specialist leak tracing equipment.

  • Is your water meter spinning when your taps are off? If your water usage is high but your internal and external taps are closed, your washing machine and dishwasher aren’t running and you see no visible signs of water above ground, it could mean that you have an underground leak.
  • Have you been surprised by usually high water bills? While it’s common for water usage to fluctuate throughout the year, if you’ve received a bill from your water company that doesn’t seem to reflect your actual usage, it may signal a hidden leak requiring immediate attention.
  • Has your heating stopped working or your boiler lost pressure? A water leak in your heating system pipework can cause your boiler to lose pressure and will most likely require professional leak detection equipment to locate.

Tracer gas leak detection

Tracer gas leak detection

The use of tracer gas is an ingenious, yet deceptively simple approach to finding a water leak in your home. In simple terms, we’ll replace the water in your pipework with a safe gas and use a sensitive above ground detector to find anywhere that it escapes.

The pressurised gas is harmless and travels effortlessly through common building materials making it the perfect way to discover the source of your leak.

Clean, non-invasive leak detection

Ironically, tracer gas leaves no trace. The gas escapes upwards from faulty pipes towards ground level allowing our technicians to detect its presence with no damage to floor, walls, ceiling or garden.

Certified for safe use in all pipework

Tracer gas is certified for use in residential and commercial pipework due to its non-toxic, non-corrosive and non-flammable properties. Our team of experts have been professionally trained in its use and have used the method to locate hundreds of water leaks in Hertfordshire, Surrey and London.

Thermal imaging leak detection

Thermal imaging leak detection

Our specialist thermal imaging equipment lets us see behind your walls or beneath your floor to spot possible hidden water leaks.

Using a thermographic (infrared) camera, we can quickly determine even the smaller change in a pipe’s temperature and begin our efforts to access and repair the problem.

Quick and effective thermal leak tracing

There’s a reason the police use infrared cameras in their helicopters. Our thermal equipment can be quickly configured for use in your home and requires zero direct access to your pipework.

See through walls (and under floors)

Just as a doctor will review an x-ray for signs of a problem, we’ do the same with thermal images of your home or garden. Sometimes our camera will alert us to a particular area and we can use another method to pinpoint the location of your leak more precisely.

Endoscopy leak detection

Endoscopic leak detection

Using a small camera and a flexible support, the process of endoscopic detection allows us to access hollow walls and recesses to look for the source of your leak. The camera’s light illuminates the cavities of your home to help the camera relay a real-time picture feed back to a screen viewed by one of our team.

Endoscopic cameras provide a convenient and highly effective method through which to closely examine pipework and defects, before full access and repair.

Perfect for tight spaces

The small size of the endoscope camera means we don’t need a large space to access a void and find your leak. Access can usually be obtained via an existing hole, crack or light fitting.

Trace & Access FAQs

Dealing with insurance companies can be a frustrating experience, especially when you’re claiming for cover you’ve probably never needed before. We’ve included some of the most common questions regarding trace and access below.

Remember, if you still have a question, you can call us now on 0800 037 7078.

 How do I know if my insurance policy includes trace and access protection?

Trace and access cover is commonly included on most buildings insurance policies but the specifics of your own protection may be limited by the location of a leak or a required excess payment.

We highly recommend calling your insurer to fully understand what you are and are not covered for as soon as you suspect that our trace and access service may be needed.

 Why should I use a specialist to find my leak instead of a local plumber?

Leak detection is a specialist form of plumbing that requires particular unique equipment and expertise beyond that carried by most general local plumbing companies. All of our leak technicians are fully qualified plumbers with the added benefit of specific and intensive training for leak detection work.

I cannot recommend Miracle Leak Detection highly enough. We've dealt with numerous tradespeople and this gentleman is an absolute star. He is a thoroughly professional guy, gave very good advice, was not pushy or over-bearing and is also a genuinely nice person. He knows his stuff and we would not go anywhere else. 10/10!

Miracle Leak Detection saved me after our boiler lost pressure in the middle of a freezing cold night. An engineer arrived the next morning after I called to look for the source of the problem.
