Leak Detection in Woking
Woking's hard water doesn't just scale radiators—it corrodes copper pipes from the inside, creating pinhole leaks that waste thousands of litres and inflate water bills. Detection isn't guesswork: our technicians use acoustic and thermal imaging to pinpoint leaks in Woking properties across GU21, GU22, GU23, and GU24 without digging up gardens or floors. Thames Water charges premium volumetric rates; finding leaks fast saves money and prevents water escape into your property's structure.
Leak detection in Woking identifies pinhole corrosion in copper pipes (caused by Thames Water's hard water), joint failures in Victorian cast-iron soil pipes, and buried-run leaks using acoustic and thermal imaging, pinpointing damage without excavation in postcodes GU21–GU24.
Drainage in Woking — what local engineers know
Thames Water supplies Woking with hard water (typically 300–350 mg/L calcium carbonate equivalent), accelerating pinhole corrosion in copper pipes installed before 2000. Cast-iron soil pipes in Victorian properties (20% of Woking stock) develop joint leaks where hard water deposits stress gaskets over decades. Edwardian homes (14%) often feature original pipework at end-of-life, making leaks inevitable. Surrey Heath Council's separate sewer requirements add urgency: leaks into surface water drains breach environmental regulations. Acoustic leak detection, thermal imaging, and tracer dye methods are non-invasive first steps in Woking, avoiding unnecessary excavation and cost.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Woking
- Separate sewer system across most of Woking: 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 Woking means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With 34% 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 Woking?
In Woking, 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, Thames 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 Surrey Heath.
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 Thames Water rather than paying for the repair yourself. The separate sewer layout that dominates Woking affects where these boundaries typically fall, and our local engineers know the GU21, GU22, GU23 networks well enough to identify ownership quickly.
Leak Detection prices in Woking
Every Woking 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.
