Leak Detection & Repair in Belfast

Vetted & insured engineers Clear pricing before work starts G3-qualified for unvented cylinders No gas work — plumbing only

If your water meter moves with every outlet closed, you have a leak. Our Belfast team confirms it, locates it non-destructively, and quotes the repair from evidence rather than guesswork.

Belfast water notes: Belfast's supply from the Mournes and Antrim hills is soft — scale is a minor factor, and the workload tilts toward the city's older terrace pipework, winter freezes and conversions. Belfast's parlour terraces off the Ormeau, Lisburn and Antrim Roads carry early-1900s plumbing bones, alongside postwar estates and the Titanic Quarter's modern apartment blocks. Mains supply here is managed by NI Water.

How non-invasive leak detection works

Each method has a job. Thermal cameras find hot-water and heating leaks fast; acoustic microphones hear mains-pressure leaks through solid floors; capacitance moisture meters map how far the water has travelled and in which direction concentration rises; tracer gas finds weeping joints that make no noise at all. Your Belfast engineer selects the combination that suits the construction and reports what was found before any repair is priced.

Signs you have a hidden leak

The classic tells in Belfast homes: a water bill that's risen with no change in use, background sound of running water at night, a warm stripe across a floor, skirting or plaster damage that returns after redecorating, and pressure loss on sealed systems. A ten-minute meter test — everything off, read, wait an hour, read again — is the cheapest first diagnostic you can do yourself.

Detection to repair, one accountable job

Once located, the repair is quoted from evidence: what pipe, what failure, what access. We open the smallest area that allows a proper repair, replace the failed section rather than patching it, and re-test at pressure. Where flooring or tiling must come up, you approve the scope first, and everything is photographed for your records or your insurer.

Leak detection cost in Belfast

A detection survey in Belfast is a from-£149 fixed band depending on property size and methods needed, agreed before booking. The repair is quoted separately once the leak is proven — you're never committed to a repair price before anyone knows what's actually wrong. Trace-and-access is commonly covered by buildings insurance; our reports are written to support that claim.

Frequently asked questions

Can you find leaks in underfloor heating in Belfast?

Yes. Thermal imaging shows the loop layout and the anomaly at the leak point, and pressure testing confirms which circuit is losing water. UFH leak repairs are precise work — locating first is essential.

What causes hidden leaks in Belfast homes?

Corrosion pinholes in ageing copper, failed soldered or compression joints, abraded pipes rubbing on joists, nail and screw punctures from past work, and weeping pushfit connections. Belfast's supply from the Mournes and Antrim hills is soft — scale is a minor factor, and the workload tilts toward the city's older terrace pipework, winter freezes and conversions.

Which areas of Belfast do you cover?

All of Belfast, including Dundonald border, Stranmillis and Cavehill, plus surrounding villages and suburbs.

How do you find a leak without ripping up floors?

Acoustic listening equipment, thermal imaging, moisture mapping and tracer gas, used in combination. The point is to prove the location from the surface so any opening-up is minimal and targeted.
