Slab leak detection in Northern Ireland
Concerned about a leak beneath a concrete floor? Start with an investigation, then agree what needs to happen before floors are opened and repairs begin.
Investigate before opening the floor
A slab leak is a leak in pipework beneath a concrete floor. Recurring damp, changes in heating-system pressure or an unusual patch of warmth can be reasons to investigate, but none confirms a hidden pipe leak on its own.
NI Leak Detection introduces independent contractors across Northern Ireland. Describe the affected rooms and what you have noticed so the contractor can assess the enquiry and agree a suitable investigation.

- Which rooms and floor finishes are affected, and when symptoms began.
- Whether damp is persistent or appears at particular times.
- Any changes in heating pressure or water use, if you have meter readings.
- Known pipe routes, previous repairs and available floor or heating plans.
- Access restrictions and who can authorise investigation and any further work.
You do not need to identify the pipe or cause before contacting us. Start with your observations; the contractor can explain which checks are appropriate.
Need help with an active leak?From suspected leak to an agreed next step
01 / Discuss
Agree the survey
Explain the symptoms and floor construction where known. Confirm the investigation scope, attendance, price and any report you need with the contractor.
02 / Investigate
Narrow down the problem
The contractor selects tests for the suspected system and explains the evidence, limitations and any further checks needed. Agree proposed opening-up before it begins.
03 / Repair
Plan access and repairs
Independent engineers usually fix leaks and carry out repairs. Confirm what can be done, what access is required, and whether further attendance or other trades are needed.
Agree what happens to the floor
Specialist investigation can help limit unnecessary opening-up, but it does not guarantee an exact access point or a damage-free result. Floor construction, finishes and pipe access affect the options.
Ask the contractor to separate investigation, opening-up, pipe repair and reinstatement in the agreed scope. Confirm who will restore the floor and finishes, and any separate costs. A detection visit does not automatically include all of this work.
About non-destructive leak detectionNeed a report for a claim?
Tell the contractor before booking if you need a leak-detection report. Agree what it will contain and whether it is included in the price. NI Leak Detection can help with a trace-and-access or water-damage claim when requested; this requires a leak-detection report.
A loss assessor’s escape-of-water damage survey is a separate service. Check cover and evidence requirements with your insurer; a report does not guarantee payment.
Read about trace and accessSlab leak-detection questions
Does damp flooring prove there is a slab leak?
No. Describe the symptoms without assuming the cause. The investigation needs to establish whether pipework is leaking and explain any uncertainty.
Will the entire floor need to be lifted?
The amount of access depends on the findings and construction. Discuss the proposed access before agreeing work; neither a single-tile opening nor a completely non-invasive repair can be promised.
Can the leak be repaired during the visit?
Engineers usually repair leaks, but the work depends on access, parts and the agreed scope. Ask what can be completed during the visit and what may need a return appointment.
Who do I book and pay 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.
