Thermal Imaging Leak Detection
Infrared surveying detects the subtle temperature differences that betray escaping hot water, hidden moisture and underfloor heating faults, all without touching a surface.
Thermal imaging in practice
Thermal imaging enables us to detect subtle temperature differences across floors, walls and ceilings that may indicate the presence of moisture or leaking pipework.
Using an infrared camera, we can identify abnormal heat patterns caused by escaping hot water, moisture affecting building materials, underfloor heating faults and hidden plumbing leaks.
Thermal imaging is entirely non-contact and non-destructive, allowing us to quickly survey large areas without causing damage. While thermal imaging does not directly see water, it provides valuable information that helps narrow down the area requiring further investigation.
Thermal imaging reveals heat patterns caused by:
- Escaping hot water
- Moisture affecting building materials
- Underfloor heating faults
- Hidden plumbing leaks
Thermal imaging: your questions
Specific answers about this method. For anything else, call us on 0333 772 4776.
Not directly; it sees temperature. Escaping hot water and evaporating moisture change surface temperatures in telltale patterns, which lets us narrow the search area before confirming the leak with other methods.
Extremely. The camera maps the heating loops through the floor and shows exactly where a loop runs cold or where heat pools abnormally, which is usually the failure point.
No. Thermal imaging is entirely non-contact and non-destructive; we survey large areas of floors, walls and ceilings without disturbing a single surface.
