Leak Detection in Wrexham
Welsh Water's soft, slightly acidic supply accelerates pinhole corrosion in copper and lead pipes throughout Wrexham. Homeowners in Victorian and Edwardian properties often discover slow leaks only when they see rising water bills or staining on ceilings in postcodes LL12 and LL13. Our non-invasive detection technology locates hidden leaks before they cause structural damage, hidden mould, or burst into flooding.
Leak detection in Wrexham identifies slow, hidden leaks caused by pinhole corrosion in copper and lead pipes. Welsh Water's soft, slightly acidic supply corrodes copper at accelerated rates, especially in Victorian and Edwardian Wrexham properties. Non-invasive acoustic and thermal imaging locates leaks without wall demolition, protecting insurance claims and preventing structural damage.
Drainage in Wrexham — what local engineers know
Wrexham Council estimates that a significant share of Victorian properties (built 1850–1920) in the LL11–LL14 postcodes have copper pipework showing pinhole corrosion. Welsh Water's supply pH sits at 6.8–7.0, slightly below neutral, allowing copper oxide to dissolve and re-deposit inside pipes as tiny holes. This process is silent; leaks often go undetected for months, wasting thousands of litres and damaging Wrexham's property values. Insurance claims for 'gradual seepage' are often denied if the leak was discoverable, so early detection is essential for Wrexham homeowners.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Wrexham properties
- Separate sewer system across most of Wrexham: 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 Wrexham 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 Wrexham?
In Wrexham, 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 Wrexham.
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 separate sewer layout that dominates Wrexham affects where these boundaries typically fall, and our local engineers know the LL11, LL12, LL13 networks well enough to identify ownership quickly.
Leak Detection prices in Wrexham
Every Wrexham 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 Wrexham 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.
