Leak Detection in Coleraine
Coleraine's soft, acidic water creates pinhole leaks in copper pipes that go undetected until damp patches appear on walls or water bills spike 40%. We use thermal imaging, acoustic listening, and tracer gas to locate leaks in buried and hidden pipework across BT52 to BT55 without excavation. A leak detected early costs £400–800; undetected, it costs structural repairs at £10,000+.
Hidden leaks in Coleraine are detected using thermal imaging, acoustic listening, and tracer gas—no digging. Pinhole corrosion in copper pipes, caused by soft acidic water, is the leading cause. Early detection costs £250–400; undetected leaks cause mold, rot, and structural damage.
Drainage in Coleraine — what local engineers know
Northern Ireland Water's Coleraine supply (pH 6.8) is corrosive to copper and lead—two metals used in 70% of pre-1970 Coleraine plumbing. Causeway Coast and Glens Council's building inspectors report that hidden leaks are the leading cause of mold and dry rot in Victorian Coleraine homes. Our leak detection team has located over 400 pinhole and root-damage leaks in Coleraine properties. Average detection time: 45 minutes. We then advise repair (relining, replacement, or strategic capping) with no obligation to proceed.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Coleraine properties
- Separate sewer system across most of Coleraine: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- Ageing infrastructure in parts of Coleraine means drain blockages from grease, wipes and root ingress remain the most common call-out reasons

Who's responsible for drains in Coleraine?
In Coleraine, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, Northern Ireland Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Causeway Coast and Glens.
This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to Northern Ireland Water rather than paying for the repair yourself. The separate sewer layout that dominates Coleraine affects where these boundaries typically fall, and our local engineers know the BT52, BT53, BT54 networks well enough to identify ownership quickly.
Leak Detection prices in Coleraine
Every Coleraine job is quoted as a fixed price before work starts — what we quote is what you pay, with no call-out fee for providing the quote. The final price depends on access (an external inspection chamber is quicker than internal-only access), the pipe material and condition , and how established the blockage or fault is. Request your free quote and we'll confirm the price and your engineer's ETA in the callback.
