Leak Detection in Caerphilly
Caerphilly's mixed property stock spans Victorian terraces through to modern builds, with a significant share of homes built before 1920. Combined sewerage means that pinhole corrosion in copper pipework—accelerated by Welsh Water's naturally soft, slightly acidic supply—can cause hidden leaks that only show as damp patches or higher water bills. We detect these leaks without tearing up floors across CF83, CF84, CF85 and CF86.
Leak detection in Caerphilly uses acoustic loggers and thermal imaging to find hidden water leaks without excavation. Critical in older properties built before 1920 where pinhole corrosion in copper pipework—driven by soft, slightly acidic water—causes damp and high water bills. Building insurers typically cover trace-and-access costs.
Drainage in Caerphilly — what local engineers know
Caerphilly falls under Cardiff council and Welsh Water's supply area. Welsh Water's soft water chemistry—whilst reducing limescale—creates slightly acidic conditions that accelerate corrosion of copper fittings and lead solder joints in older properties across CF83 and CF84. Combined drainage infrastructure means surface water and foul water share the same pipe, raising blockage and surcharge risk in heavy rainfall. Hidden leaks in foundations, heating systems and under-floor runs are among the most frequent call-outs in properties with ageing clay and cast-iron pipework. Acoustic monitoring and thermal imaging pinpoint the exact location without excavation.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Caerphilly properties
- Combined sewerage infrastructure — common in older parts of Caerphilly — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
- Ageing infrastructure in parts of Caerphilly means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With a significant share 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 Caerphilly?
In Caerphilly, 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 Cardiff.
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 Caerphilly affects where these boundaries typically fall, and our local engineers know the CF83, CF84, CF85 networks well enough to identify ownership quickly.
Leak Detection prices in Caerphilly
Every Caerphilly 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 Caerphilly 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.
