Leak Detection in Grantham
Grantham's hard water supply accelerates pin-hole corrosion in copper pipework—a creeping problem often invisible until rot appears in walls or ceilings. Properties across Grantham postcodes NG31, NG32, NG33, and NG34 sit on Anglian Water's notoriously hard supply, making silent leaks a recurring risk in Victorian and Edwardian stock. Early detection stops the damage before it becomes structural.
Leak detection in Grantham identifies hidden water loss in copper and iron pipes corroded by Anglian Water's hard supply. Thermal imaging and acoustic sensors locate leaks behind walls, under flooring, and within radiator circuits before saturation causes structural damage in Victorian and Edwardian homes across NG31, NG32, NG33, NG34 postcodes.
Drainage in Grantham — what local engineers know
Anglian Water's supply to Grantham (and South Kesteven council area) has a hardness of 280–320 mg/L calcium carbonate—among England's hardest. This accelerates corrosion in older copper pipe runs and solder joints, and also creates mineral deposits in ferrous pipes that eventually perforate. Grantham's separate sewer system means surface-water leaks often go unnoticed for weeks. Water-authority bills spike sharply when even small weeps persist.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Grantham
- Separate sewer system across most of Grantham: 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 Grantham means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With 32% 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 Grantham?
In Grantham, 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, Anglian 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 South Kesteven.
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 Anglian Water rather than paying for the repair yourself. The separate sewer layout that dominates Grantham affects where these boundaries typically fall, and our local engineers know the NG31, NG32, NG33 networks well enough to identify ownership quickly.
Leak Detection prices in Grantham
Every Grantham 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.
