How can you find a water leak?

There are many ways to find water leaks, both big and small. Depending on the size of your home or business, and the location of the potential leak, there are different methods you can use to track it down.

Here are some tips:

  • NCheck all exposed pipes for moisture or wet spots; this is often a telltale sign that there is a slow drip somewhere along the line.
  • NAnother way to find tiny leaks (or those hidden behind walls) is by scanning your property with a thermal imaging camera—this will show any temperature differences caused by water seeping through cracks or holes.

If you have access to your home’s main water shut-off valve, another method is shutting off all appliances and fixtures that use water in your home, then checking your meter reading after two hours has passed; if the dial continues moving even when nothing should be running, chances are good you’ve got a leak somewhere.

What are the signs to look out for?

Water leaks can have many different signs, some more clear than others. However, these may be included – rapidly using up water, seeing damp patches on walls or ceilings, navigating through higher humidity/moisture or condensation levels inside a property or encountering strong smells. Other signs to look out for include hearing the sound of running water when none should be present, issues with your boiler losing pressure suddenly as well as structural problems – spongy flooring and cracking/visible water stains/damp. Don’t wait, book a leak detection survey today!

Who is responsible for fixing water leaks at a property?

According to most laws, if the sewage or water is on your land, then it becomes your responsibility. However, if the pipes are located elsewhere, such as pavements or roads (external to your property), then it typically falls under the local water company’s duty. It’s important to remember that you might be able to use ‘trace and access’ cover on your insurance policy for water leakages.

Will my property get damaged when carrying out leak detection work?

To avoid damaging your property, we recommend always using non-invasive leak detection methods. In some cases, however, we may need to make tiny holes – for example, to allow a borescope camera inside a wall or area under the floorboards so that we can see and identify the water leak.

Do you have to turn off the water to find the leak?

Depending on the location of the water leak, we may need to turn your water off for a short period of time. However, we will always consult with you before doing so and only keep the water off for as long as necessary. In some cases, we won’t need to turn your water off at all.

How long will it take you to find the leak?

This is not a straightforward question to answer, as it will depend on the individual case. However, we can say that in most cases, this will be done within a day. It usually only takes a few hours, but it depends on how hidden the leak is and its size of it. The layout of your property can also play into how long fixing the issue will take. We would be happy to discuss this with you further when we come to do your leak detection survey.

What makes a water leak detectable?

Our leak detection team is specifically trained to notice clues that allude to water leaks, investigate them using high-tech equipment, locate the source of the leak, and identify its root cause. These telltale signs can be anything from moisture levels (detected with a moisture meter) and acoustic or thermal readings (picked up by acoustic or thermal imaging leak detection) to more pungent odours or visible indications of a problem.


How can a property be dried after a water leak?

Depending on the part of your house affected by the water leak and what materials are involved, we will use dehumidifiers, air movers/fans, and sometimes heaters to dry out your home. Sometimes, we need to use water pumps (for example, in flooded basements).

Will you provide a water leak detection report?

Yes, we can give you records of the investigations and work we have done – this comprises proof we have gathered during. This could be handy to provide your insurance company with several motives, not limited to the fact that they may pay for it!
