About Us
Addlestone is a north Surrey commuter town with a layered housing history, and that shapes the kind of work we do here. Victorian and Edwardian terraces sit near the centre around Chertsey Road and Woburn Hill, while the 1950s and 1960s commuter boom filled out New Haw and Woodham with suburban semis along Woodham Lane. More recently, the Addlestone ONE regeneration added a layer of town-centre flats. Many of the older homes across KT15 still have lead supply lines in the ground. Addlestone sits within the area we cover, alongside nearby places we serve such as Woking, West Byfleet and Guildford.
Wherever you are in the town, our process is the same. We dig two small access pits, one near the boundary stop tap and one near the property, then drive an impact mole between them and pull a new MDPE supply pipe through behind it. Your driveway, lawn, patio and any paving stay intact, and most Addlestone jobs are completed in a single day.

What is Moling?
Trenchless moling is a no-dig method of replacing a buried water supply pipe, and it suits Addlestone’s ground particularly well. The town sits on London Clay overlain by Thames river-terrace sands and gravels, so the soil shifts from heavy, slow-draining clay to free-draining gravel within a short distance, often with high groundwater close to the surface. Open trenching through that mix is slow and messy. With moling, we excavate two small pits (one near the boundary stop tap, one where the pipe enters the property), drive an impact mole through the ground between them, and pull a new MDPE pipe in behind it. The old lead pipe is disconnected at both ends and left in the ground, and the route in between is undisturbed. On Addlestone’s clay-and-gravel terrain, leaving that ground intact is a real advantage over a full open dig across your front garden.
Why Replace Lead Pipes?
Addlestone is supplied by Affinity Water, and the water here is hard, around 255 mg/l as calcium carbonate. The lead in tap water comes from the old pipe itself, dissolving into water that has been standing overnight in an ageing lead line. Combined with the town’s stock of pre-war and post-war housing, that means a fair number of original lead supply lines across KT15 are still in service.
Most Addlestone homeowners get in touch after one of these:
- A failed lead test or a flag from their plumber
- A letter from Affinity Water about lead in the supply
- Discoloured or metallic-tasting tap water
- Noticeably low water pressure compared to neighbours
- A solicitor or surveyor raising it during a property sale
Replacing the lead supply pipe with modern MDPE via moling is the standard fix, and on most Addlestone properties it’s a single-day job that leaves your surfaces as we found them.
