Hidden leaks can cause major damage if left untreated. From slow drips behind walls to heating system faults beneath floors, our team in Belfast specialises in non-invasive leak detection.

We use:

• Thermal imaging cameras to scan walls, ceilings, and floors for signs of hidden water.
• Acoustic microphones to listen for pipe leaks under concrete and tiled areas.
• Tracer gas technology to detect small leaks in central heating and sealed systems.
• Moisture mapping to confirm damp spots and assess water spread.

Case study:
A homeowner in South Belfast reported damp patches in their living room. Our engineers used infrared thermography to locate a leaking pipe joint beneath the floorboards. Only a small section was lifted, the repair was completed the same day, and the insurer accepted our Trace & Access report without issue.

Finding a leak is only half the job. At NI Leak Detection, our qualified plumbers in Belfast repair most leaks the same day, so you don’t need to bring in a second contractor.

We carry out:

• Pipe joint repairs – fixing small but persistent leaks in copper and plastic pipework.
• Central heating and boiler repairs – sealing leaks in radiators, valves, and underfloor heating systems.
• Underfloor and concealed pipe repairs – accessing hidden pipework with minimal disruption.

Our diagnostic credit promise means if a leak isn’t found on the first visit, your diagnostic fee is credited towards the repair — keeping costs fair and transparent.

Case study:
In Andersonstown, West Belfast, a burst joint on a central heating pipe was causing loss of boiler pressure. Our team located the fault using acoustic detection, lifted only one tile, and completed the repair the same day. The client recovered costs under their Trace & Access insurance cover.
