A local job example

Targeted access beneath a concrete floor

Lisburn · Detached home · Around May 2026

The problem

We received an enquiry about a hidden leak beneath the solid concrete floor of a Lisburn home. Finding the affected pipe before opening the floor was central to the investigation.

The investigation

The engineer combined thermal imaging with tracer gas testing to locate the leak. The results guided a small excavation over the affected section of pipe.

The outcome

The pipe was repaired during the same visit. A trace-and-access report recorded the investigation and repair for the homeowner’s insurer.

Start with the symptoms

You do not need to know where the leak is before calling. Explain what you have noticed and any previous tests or repairs. The investigation is chosen to suit the symptoms, pipework and access.

Know what happens after it is found

Specialist methods help focus access where it is needed. Engineers usually repair leaks too, but the findings, access and parts determine what can be completed during the visit. Agree the repair scope and price before work begins.

Questions before you book

Can you attend urgently in Lisburn?

Call to explain the urgency and confirm availability. If water is actively escaping, use the telephone rather than waiting for a callback. An enquiry does not book an emergency visit.

What will the survey cost?

The quote depends on the property and problem. Agree the investigation price before booking and ask about separate access, repair, report or attendance charges.

Will the engineer repair the leak?

Engineers usually repair leaks. Completion during the detection visit depends on the findings, access, parts and agreed scope. Ask what is included and whether further attendance is needed.

Will walls or floors need to be opened?

Specialist checks help narrow down the source and focus access work. A floor or wall may still need opening to reach the pipe. Agree any access and making-good work before proceeding.

Can I get a report for an insurance claim?

Tell us before booking. A leak-detection report is needed for claims assistance following a leak; agree its content and cost with the contractor. PCLA’s optional water-damage survey and claims service are separate. Insurance cover depends on your policy and circumstances.

Who carries out and charges for the work?

You contract with and pay the independent contractor directly. NI Leak Detection arranges the introduction and receives no commission or financial reward for it.
