Thermal Imaging Leak Detection in Northern Ireland

If you’ve noticed damp patches, staining, recurring mould, or a pressure drop in your heating system and you can’t see an obvious cause, thermal imaging can help narrow the search.

We use infrared imaging as part of a structured leak investigation to identify temperature patterns that may be linked to hidden leaks, so any access and repair work can be more targeted.

Thermal Imaging Leak Detection in Northern Ireland

When people usually look for thermal imaging

Thermal imaging is often useful when you have symptoms like:

  • Damp patches that keep coming back
  • Ceiling stains below a bathroom or pipe run
  • Wet flooring, lifting laminate, or musty smells
  • Recurring mould on an outside wall or internal partition
  • Boiler pressure dropping or heating not behaving normally
  • A suspected underfloor heating issue

Need advice?

If you are unsure whether it's a leak, we can talk through what you're seeing and advise what to check next.

What thermal imaging leak detection actually does

Thermal imaging cameras measure surface temperature differences.

In the right conditions, those temperature patterns can indicate areas affected by:

  • Heat loss from hot water or heating pipework
  • Moisture movement that's cooling a surface as it evaporates
  • Affected zones around pipe runs, floors, or walls

Thermal imaging does not "see through" walls or floors. It reads surface temperatures, and we interpret what we see in context with your symptoms and the building materials.

When thermal imaging is useful, and when it isn't

Thermal imaging can be useful for

  • Heating system leaks, including suspected underfloor heating zones
  • Hot water pipework where heat patterns help identify a likely route
  • Large areas where guesswork could lead to unnecessary opening-up
  • Damp or staining where the source is unclear and needs narrowing down

Thermal imaging has limits

It may be less helpful on its own when:

  • The suspected leak is on cold mains water
  • Insulation, drafts, or recent heating use affects readings
  • The surface material makes interpretation difficult

In those cases, we may use other checks to confirm the source and location.

How our thermal imaging process works

We keep the approach simple and clear, so you know what's happening.

  1. 1

    Symptom review

    You tell us what you've noticed, where it's happening, and how long it's been going on.

  2. 2

    Targeted checks

    We assess likely systems and zones, such as heating, hot water, cold supply, bathrooms, or pipe runs.

  3. 3

    Thermal scan

    We scan the relevant areas and look for unusual temperature patterns that may help narrow the search.

  4. 4

    Confirm the source and location

    Where needed, we use additional checks to verify what the imaging is suggesting.

  5. 5

    Next steps explained

    We explain what we've found and talk you through repair options and any access work that may be needed.

Repairs can sometimes be carried out on the day, depending on what's found, access, and parts required. If a repair needs more time or specialist access work, we'll explain the options before anything proceeds.

What you get at the end of the visit

You'll leave the visit with:

  • A clear explanation of what we found
  • The most likely source and location, where it can be determined
  • Practical next steps to stop the problem and limit further damage
  • Photos and thermal images where they help show the affected area
  • Repair options explained, with no pressure to proceed beyond what's agreed

Thermal imaging and insurance documentation

Some home insurance policies include Trace and Access cover. This can contribute towards the cost of locating and exposing a hidden leak, but cover depends on your policy terms and your insurer’s decision.

If you need documentation for an insurance query, we can provide a clear report with supporting notes and images, based on the investigation carried out.

We do not handle claims on your behalf, but we can provide information that may help you communicate what was found.

Common scenarios we see

These are a few examples of where thermal imaging can help as part of the investigation:

Ceiling stain below a bathroom

Imaging can help narrow the likely route of pipework before targeted access is considered.

Heating pressure dropping

Thermal patterns may help identify a suspect zone, with follow-up checks used to confirm.

Damp patch with no visible source

Imaging can help prioritise the most likely area to investigate, reducing guesswork.
