Advanced Leak Detection
Without Unnecessary Damage
Hidden water leaks can result in serious water damage, mould growth and further damage to property if not identified quickly. Invasive investigation can often cause more damage than the leak itself.
Our specialist leak detection services use advanced leak detection systems and equipment to detect leaks accurately while causing minimal damage to the building structure.
Techniques we use include:
- Thermal imaging to trace moisture and temperature differences
- Tracer gas to identify hard to find heating system leaks and water pipes
- Acoustic listening devices and water leak detectors
- Pressure testing for central heating systems and plumbing networks
- Targeted investigation of boilers, valves and pipework
Whether the issue relates to central heating system leaks, external leaks, commercial leak scenarios or pressure loss in a heating system, our engineers have the knowledge and expertise to deal with the problem efficiently.
By identifying leaks early, we help prevent more damage, reduce repair costs and protect the long term integrity of your commercial buildings.
