Leak Detection in Llandudno
Pinhole corrosion in copper pipework is endemic in Llandudno, caused by the soft water supplied by Welsh Water and its slightly acidic pH. Tiny holes appear silently in pipes behind walls and beneath floorboards across Llandudno (LL30–LL33), causing water loss, damp, and expensive remedial work. Early detection prevents thousands in water damage and mold remediation.
Leak detection in Llandudno uses acoustic, thermal, and radar technology to locate hidden leaks from pinhole corrosion and cast-iron decay. Soft water from Welsh Water accelerates copper corrosion; early detection saves thousands in water bills and structural repair.
Drainage in Llandudno — what local engineers know
Welsh Water's supply to Llandudno is famously soft, which prevents limescale but leaves pipes vulnerable to corrosion. Victorian properties in Llandudno have original copper pipework that may be 100+ years old; Edwardian properties also commonly feature copper now at the stage of pinhole failure. Conwy Council's building inspection data shows that Llandudno's older residential stock (24% Victorian, 12% Edwardian) bears high rates of concealed corrosion damage. Cast-iron drains in Llandudno are equally susceptible to rust and perforation. When damp or rising water bills signal a leak, underground detection using acoustic and thermal imaging can locate the exact fault point without excavation in LL30–LL33 properties.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Llandudno properties
- Combined sewerage infrastructure — common in older parts of Llandudno — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
- Ageing infrastructure in parts of Llandudno means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With 36% of properties built before 1920, salt-glazed clay drainage and lead-solder copper pipework are common — pipe collapse, root ingress and joint failure are recurring call-out drivers.

Who's responsible for drains in Llandudno?
In Llandudno, 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, Welsh 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 Conwy.
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 Welsh Water rather than paying for the repair yourself. The combined sewer layout that dominates Llandudno affects where these boundaries typically fall, and our local engineers know the LL30, LL31, LL32 networks well enough to identify ownership quickly.
Leak Detection prices in Llandudno
Every Llandudno 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.
