Leak Detection in Petersfield
Petersfield's Thames Water hard supply causes pin-hole corrosion in copper pipework—microscopic holes that weep water into walls and under floors, remaining invisible for months. Victorian properties in postcodes GU31 and GU32 often contain cast-iron drainage that rusts and develops pinpoint leaks, slowly saturating masonry. A water bill spike, damp patches creeping across plaster, or mould on interior walls signals a hidden leak in Petersfield requiring professional detection before structural damage escalates into dry rot and timber decay.
Hidden leaks in Petersfield typically result from pin-hole corrosion in copper pipes caused by Thames Water's hard supply, or rust perforation in Victorian cast-iron drainage. Leak detection equipment in Petersfield uses acoustic and thermal imaging to locate water escapes without excavation, preventing wall damp, mould, and structural damage from prolonged water ingress into Petersfield masonry foundations.
Drainage in Petersfield — what local engineers know
Thames Water's hard supply across Petersfield (GU31, GU32, GU33, GU34) accelerates corrosion in copper pipes—pin-hole leaks are the signature failure mode in Petersfield. East Hampshire council building control requires leak repairs to meet damp and mould regulations. Petersfield's Victorian and Edwardian housing stock contains cast-iron waste pipes and clay foul drains; both corrode and crack over 120+ years. Detecting leaks early in Petersfield prevents costly structural repairs—dry rot, timber decay, and foundation settlement follow prolonged water ingress.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Petersfield
- Separate sewer system across most of Petersfield: 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 Petersfield 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 Petersfield?
In Petersfield, 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 East Hampshire.
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 Petersfield affects where these boundaries typically fall, and our local engineers know the GU31, GU32, GU33 networks well enough to identify ownership quickly.
Leak Detection prices in Petersfield
Every Petersfield 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.
