Leak Detection in Holywood
Holywood's soft-water supply is a double-edged sword: it prevents limescale buildup but the slightly acidic pH aggressively corrodes copper fittings. Pin-hole leaks emerge silently in Holywood homes, often going unnoticed until water staining or mould appears. Detecting these leaks early protects your Holywood property from hidden damage and saves thousands in remedial work.
Leak detection in Holywood identifies pin-hole corrosion, usually caused by soft water attacking copper fittings. Acoustic and thermal imaging pinpoint leaks in Victorian and Edwardian properties across BT18, BT19, BT20, BT21 without damaging walls.
Drainage in Holywood — what local engineers know
Northern Ireland Water supplies Holywood with notably soft water (typically 50–80 mg/L hardness), which is gentler on boilers but devastating for copper longevity. Holywood's Victorian properties (especially BT18 and BT19) contain original copper pipework installed in the 1920s–1950s, when corrosion inhibitors were rarely used. The town's separate sewer system also means leak detection requires careful distinction between foul and surface water drains — a critical factor for environmental compliance in Holywood. Belfast council enforces water-company advisories about corrosion in Holywood postcodes BT20 and BT21.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Holywood properties
- Separate sewer system across most of Holywood: 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 Holywood means drain blockages from grease, wipes and root ingress remain the most common call-out reasons

Who's responsible for drains in Holywood?
In Holywood, 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 Belfast.
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 Holywood affects where these boundaries typically fall, and our local engineers know the BT18, BT19, BT20 networks well enough to identify ownership quickly.
Leak Detection prices in Holywood
Every Holywood 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. However, 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.
In summary, Leak Detection in Holywood is backed by a 12-month workmanship guarantee. Furthermore, every job includes a written completion report. Consequently, you have full documentation if the same fault recurs.
