Think you might have a leak?

Signs of hidden leaks include damp patches, mould, reduced water pressure, and unexplained high bills. Our engineers can locate the source quickly—saving you time, stress, and unnecessary repair costs.

Our Technology That Finds Leaks Without Damage

We use a combination of non-destructive technologies to find the exact source of hidden water leaks. Each method helps us locate the problem quickly, reduce disruption to your property, and provide clear evidence for repair and insurance purposes.

Acoustic Leak Detection

'We listen for the leak.' Using acoustic microphones, we detect escaping water inside mains or central heating pipes without lifting floors or breaking walls.

Thermal Imaging

'We see what the eye can’t!'. Infrared thermal cameras show heat patterns that reveal hidden water leaks under floors, behind walls, or within heating systems.

Tracer Gas Testing

'We trace leaks others can’t reach.' A harmless gas is introduced into the pipework, and our sensors follow its path to locate buried or concealed leaks with precision.

Moisture Mapping

'We track where the water’s gone.' Moisture meters measure damp levels across surfaces, helping us confirm the leak source and document the extent of water damage.

FAQs – Leak Detection Coleraine

We prioritise Coleraine call‑outs and can usually attend the same day. For urgent issues (visible damp, ceilings at risk, or heating system losing pressure), we aim for a 2–4 hour response where possible. We cover the town centre and surrounding areas including Mountsandel, Portstewart Road, Ballycairn, and the North Coast corridor. When you call, we’ll assess the severity and book the earliest viable slot. If appropriate, we’ll also give you interim steps to reduce damage before we arrive.

That’s a last resort. Our approach is non‑invasive: thermal imaging to see temperature changes, acoustic listening to pinpoint pipe noise, tracer gas to locate hidden escapes, and moisture mapping to trace the path of water. In most homes we identify the source without any destructive work. If access is necessary, we keep it precise (think a neat inspection hatch rather than a large area lifted) and we’ll always explain why before we proceed.

For most domestic properties, professional leak detection is typically quoted as a fixed visit fee so you know the cost upfront. Prices vary by property size and the techniques required (for example, tracer gas uses specialist consumables). You’ll get a clear, itemised estimate before work begins—no hidden extras. Where relevant, we split detection and access on the invoice so you can use your policy’s trace and access cover if included.

Yes. Many home insurance policies include trace and access cover under Escape of Water. We provide a formal report with photos, test findings, and the exact location of the leak to support your claim. We can also liaise with your insurer or loss adjuster if needed and advise what evidence they typically require. If you’re unsure about your cover, we’ll talk you through the key sections to check before we start.

Tell‑tale clues include: a boiler or heating system losing pressure, warm patches on the floor (underfloor heating), persistent musty odours, discoloured paint or plaster, swollen skirting boards, or a water meter that moves when all taps are off. In Coleraine’s mix of newer estates and older homes, hidden pipe runs in screed or behind plasterboard can mask issues. If in doubt, a non‑invasive survey is the fastest way to confirm.

A plumber fixes; a specialist finds—accurately. We use advanced diagnostics to locate the problem area first, so any subsequent repair is targeted and cost‑effective. This avoids guesswork and large exploratory works. In practical terms, it means less disruption, fewer reinstatement costs, and a quicker path to drying and repair—especially important in properties near the River Bann where moisture control is critical.

Most investigations take 1.5–3 hours. We begin with a brief interview about symptoms, then carry out targeted tests. Before we leave, we explain the findings clearly, advise on immediate steps to prevent further damage, and outline repair options. You’ll receive a written report (with photos) for your records and insurance. If you want us to manage or quote the repair, we can arrange that promptly.

Absolutely. We serve Coleraine and nearby areas including Portstewart, Portrush, Castlerock, Articlave, Macosquin, and Ballymoney. Whether you’re in an older property off Mountsandel Road or a newer development towards University Road, we’re familiar with the typical plumbing layouts and materials used locally, which helps us diagnose faster and minimise disruption.
