Water leaks inside a property are often hidden out of sight, making them one of the most frustrating problems for homeowners and businesses. Left undetected, they can cause costly structural damage, create health risks from damp and mould, and significantly increase water bills.

At Hamblin Watermains, we provide expert internal water leak detection, helping you identify leaks early and resolve them before they escalate into more serious issues. Investing in early internal leak detection can save significant costs and prevent extensive damage in the long run. With over 50 years of experience, our dedicated team is trusted across the South East to deliver reliable, non-invasive solutions that protect your property.

What Is Internal Leak Detection?

Internal water leak detection is the process of locating hidden water leaks within a property’s plumbing system. Unlike an external leak, which typically occurs in pipes outside of the property boundary, such as in external water supply lines or mains, internal leaks often develop within pipes behind walls, under floors, or in ceilings where they cannot be seen. Because they are concealed, they may go unnoticed for long periods, leading to expensive water damage before being discovered.

At Hamblin, we use advanced technology such as acoustic listening devices, thermal imaging, and moisture meters to detect the exact source of the problem. This approach means leaks can be precisely located, even within pipes hidden behind walls or under floors, without the need for unnecessary excavation or disruption. By investing in professional internal water leak detection, property owners can avoid guesswork, prevent ongoing damage, and ensure their home or business remains safe and secure.

Signs You May Have an Internal Water Leak

Spotting the signs of an internal leak early is vital in order to avoid costly repairs. One of the most common indicators is an unexplained increase in your water bills, particularly if your water usage has not changed. Damp or discoloured patches on walls, ceilings, or flooring can also signal water building up in hidden areas. Another warning sign is hearing the sound of dripping or running water when no taps or appliances are in use.

A dripping tap is another sign to watch for, as it can lead to significant water wastage and may indicate a worn-out washer or other issues. Mould growth and musty smells often point to excess moisture caused by leaks, which can also impact health. In some cases, you may notice a significant drop in water pressure, or find that water is not flowing properly from your taps, which suggests that water is escaping from your system before reaching your taps.

If you recognise any of these symptoms, it is important to arrange professional leak detection as soon as possible. Leaks can also occur in heating systems, so professional assessment by plumbers or heating engineers may be necessary to prevent water wastage and damage.

Internal Leak Detection FAQs

How do you detect internal water leaks?

We use specialist technology including acoustic listening devices, moisture meters, and thermal imaging to locate leaks hidden behind walls, under floors, or within ceilings. Leaks can also occur in the supply pipe running from the water mains to your property, and advanced methods are used to detect leaks in water supply pipes and repair the water pipes, even those buried underground or within walls. These methods allow us to identify leaks accurately without causing unnecessary disruption to your property, ensuring the process is efficient, precise, and cost-effective for homeowners and businesses alike.

Can you repair the leak once it is found?

Yes, in most cases we are able to carry out repairs once the leak has been detected. Our fully trained engineers are experienced in repairing leaks in a variety of systems, replacing lead water pipes and resolving a wide range of issues, from minor leaks in internal pipework to more complex problems within a property’s plumbing system. This allows us to offer a complete service from detection through to repair.

How much does internal leak detection cost?

The cost of internal leak detection varies depending on the size of the property, the complexity of the plumbing system, and the location of the leak. We believe in full transparency, so we provide clear pricing information before any work begins. This ensures customers understand the costs involved and feel confident they are receiving value for money.

How long does leak detection take?

The time required for internal water leak detection depends on the property and the severity of the issue. In many cases, we are able to complete the process within a few hours. Our engineers use advanced equipment to locate leaks quickly and accurately, allowing us to minimise disruption while still ensuring that the problem is resolved properly.

Do I really need internal leak detection if I only see a small damp patch?

Yes, even a small damp patch can be a sign of a much larger hidden problem. Water leaks often spread behind walls, beneath flooring, or within ceilings, where they cause damage that is not immediately visible. Our professional internal leak detection identifies the true source of the issue early, helping to prevent structural damage, mould growth, and expensive repairs in the future.
