When a customer in Newtownards noticed their boiler pressure dropping and unexplained damp patches appearing on the floor, they called B Keenan Plumbing & Heating to investigate. Our leak detection team was dispatched to quickly locate and repair the source of the problem before it caused further damage.
The Challenge
Heating system leaks can be difficult to pinpoint — especially when they’re hidden beneath floors or behind walls. In this case, there were no visible signs of escaping water above ground level, making it impossible to know exactly where the issue was without specialist equipment.
The property owner had already experienced a steady loss of boiler pressure and was concerned about the long-term damage that a hidden leak could cause to their home and heating system.
Our Leak Detection Process
Our experienced engineer arrived equipped with the latest leak detection technology, including thermal imaging and acoustic listening devices. This advanced, non-invasive approach allowed us to locate the leak without unnecessary floor removal or disruption.
After a full survey, our diagnostics confirmed that a leak on the central heating pipework was present beneath the floorboards in one section of the living area. The exact spot was identified quickly and efficiently — saving hours of guesswork and minimising property damage.


The Solution
Once the leak location was confirmed, our team carefully lifted the flooring and exposed the affected section of pipe. The damaged joint was repaired, and the system was refilled, repressurised, and tested thoroughly to ensure there were no further leaks.
By using modern detection methods, we were able to complete the job in a single visit, keeping disruption to an absolute minimum.
The Outcome
✅ Leak located precisely without unnecessary excavation
✅ Heating system restored to full pressure
✅ Minimal damage to flooring and décor
✅ Fast turnaround — problem resolved the same day
