Leak Detection in Slough
Slough's hard-water supply (Thames Water) accelerates pin-hole corrosion in copper pipes, making hidden leaks common in properties across SL2 and SL3. Older cast-iron and galvanised pipes in Edwardian properties often develop pinholes or slow seeps that aren't immediately visible. Detecting these leaks early saves money on your water bill and prevents structural damage to properties in Slough.
Leak detection in Slough uses acoustic sensors and thermal imaging to find pinhole corrosion in copper pipes and slow seeps in cast-iron or galvanised pipework. Hard-water scale damage is the primary cause. Detection takes 1–2 hours and pinpoints the exact leak location.
Drainage in Slough — what local engineers know
Thames Water's hard-water supply creates unique leak patterns in Slough. Copper pipe corrosion (pin-hole pitting) is the leading cause of slow, hidden leaks in post-1950s homes. Slough Council's building records show that a notable share of Edwardian properties here still use galvanised steel pipework, which is prone to internal scaling and rust perforation. The separate sewer system means external leaks can go unnoticed until damage appears in walls or foundations. Properties in SL1 experiencing water meter creep but no visible leaks almost always have pin-hole corrosion in the hidden sections of their supply line.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Slough
- Separate sewer system across most of Slough: 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 Slough 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.
- Slough has Environment Agency flood warning areas nearby along the River Thames corridor — basement and ground-floor properties can face sewer backflow during heavy rain; non-return valves are strongly recommended.

Who's responsible for drains in Slough?
In Slough, 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 Slough.
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 Slough affects where these boundaries typically fall, and our local engineers know the SL1, SL2, SL3 networks well enough to identify ownership quickly.
Leak Detection prices in Slough
Every Slough 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 Slough 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.
