Leak Detection FAQ – North London

What does a leak detection service involve?

Leak detection involves a structured inspection using specialist equipment to locate hidden water leaks. The process depends on the type of system, access available, and the symptoms observed on site.

In most cases, we use a combination of non-invasive methods to narrow down the affected area before any opening up is considered.

What types of leaks can you find?

We investigate a wide range of leaks in domestic and light commercial properties.

  • Underground water supply leaks
  • Leaks within walls, floors, and ceilings
  • Underfloor heating system leaks
  • Central heating pipework leaks
  • Intermittent or hard-to-trace leaks

What equipment do you use for leak detection?

We use a range of professional leak detection equipment depending on the situation. This may include acoustic listening devices, thermal imaging cameras, tracer gas systems, pressure testing equipment, moisture meters, and pipe tracing tools.

All equipment is selected to provide accurate results while minimising disruption. Where appropriate, multiple methods may be combined as part of a structured investigation.

For those who require further technical detail, equipment used by professional leak detection specialists is manufactured by companies such as

Sewerin

FLIR

Tramex

Is leak detection accurate without digging?

Modern leak detection methods are designed to locate leaks with a high level of accuracy without unnecessary excavation. Techniques such as acoustic detection, tracer gas, and thermal imaging allow us to narrow down the affected area before any opening up is required.

The level of accuracy depends on site conditions, pipework, and access, and in many cases a combination of methods is used to improve confidence in the findings.

Will you need to dig or open up walls?

In most cases, no. Our aim is to reduce unnecessary disruption by narrowing down the likely leak location using non-invasive methods.

If opening up is required, this is usually limited to a small, targeted area and only recommended once sufficient evidence has been gathered.

How long does a leak detection visit take?

A typical visit takes between 3 and 4 hours depending on the complexity of the issue, the size of the property, and the type of system being investigated.

More complex or intermittent issues may take longer, particularly where multiple methods are required.

Do I need to prepare anything before the visit?

Yes, a small amount of preparation helps improve the accuracy of the inspection.

  • Avoid using hot water for at least 3–4 hours before the visit where possible
  • Ensure access to affected areas, meters, and plant rooms
  • Provide any relevant background information or previous reports
  • Ensure parking is available close to the property

Can you detect leaks in underfloor heating systems?

Yes. Underfloor heating leaks can be investigated using a combination of thermal imaging, tracer gas, and pressure testing depending on the system and conditions.

These methods help identify the likely area of concern before any intrusive work is carried out.

Do you provide a report?

Yes. All leak detection visits include a clear explanation of findings, and where required, a written report with supporting images and recommendations.

 

  • Summary of findings
  • Photographic and/or thermal images where applicable
  • Explanation of likely cause
  • Recommended next steps
  • Documentation suitable for insurance claims where relevant

Is your report suitable for insurance claims?

In many cases, yes. Our reports are designed to clearly document the findings and support repair planning, which may assist with insurance claims.

Requirements can vary between insurers, so we recommend checking with your provider if you are unsure.

We provide leak detection services across North London and surrounding areas.

If you are unsure whether we cover your location, please get in touch and we will confirm availability.

What happens after the leak is found?

Once the likely leak location has been identified, we explain the findings clearly and outline the most sensible next step.

This may involve repair work, further investigation, or targeted opening up depending on the situation.

Do you carry out repairs?

Our primary focus is leak detection and diagnosis. Where appropriate, we can provide guidance on repair options or refer you to a suitable contractor.

This ensures the investigation remains independent and focused on accurate diagnosis.
