We replace lead pipes and old water mains using moling and trenchless techniques. Less mess, faster job, lower cost — and your block paving stays exactly where it is.
Tell us where and what — we’ll come back within the hour.
Traditional pipe replacement means tearing up everything in the way. Moling pulls a brand-new MDPE pipe through a single underground bore — leaving lawns, paving, and tarmac untouched.
Two small access pits at each end — block paving, lawns and patios stay intact, so you save hundreds in reinstatement costs.
Most domestic supply replacements are completed inside a single working day — water back on the same evening.
We install WRAS-approved blue MDPE — the same modern polyethylene pipe used by water companies, with a 25-year design life.
Replace your old lead supply with food-grade MDPE and remove the health risk for good — particularly important for young families.
No skip hire, no jackhammers, no patio relays. We pass the savings on — and there’s no surprise reinstatement bill at the end.
We backfill, reinstate the two access pits, sweep up and leave the site as we found it. No surprises, no half-finished mess.
Moling is a no-dig technique used for replacing water mains and laying new supply pipes. A small pneumatic “mole” is launched underground from one side of your property and travels in a straight line beneath driveways, lawns and roads to the other side.
Once the mole arrives at the receive pit, the new MDPE pipe is connected and pulled back through the bore. The result: a brand-new, lead-free water supply with only two small access holes to fill in.
Most domestic moling jobs run 4–8 hours, with the water turned back on the same day.
Send a few details — postcode, what’s wrong, when you’d like it done. We come back within the hour with a fixed price.
If needed, we visit to plan the bore line, confirm pipe length, and check the route is clear of obstructions.
We dig two small access pits, mole through the ground and pull a new WRAS-approved MDPE pipe into place.
Pits backfilled, ground reinstated, water tested and turned back on. We hand over paperwork and walk you through it.

Replaced our lead supply pipe in a single morning. Two small holes in the lawn and you’d never know they were here. Honest pricing, did exactly what was quoted.DSDaniel S.Portsmouth · Lead pipe replacement
Burst main on a Sunday — they were out within an hour, isolated the leak, and had us back on by the afternoon. Saved the block paving I was dreading losing.RPRachel P.Guildford · Emergency mains
Brought a new water supply 30 metres across the front garden without lifting the gravel drive. Brilliant work and far cheaper than the quotes from bigger firms.MJMark J.Newbury · New supply install

For a standard domestic supply replacement (around 10–25 metres), we’re usually on and off site within a single day — often by lunchtime. Larger or longer runs may need a second day for reinstatement.
The whole point of moling is that we don’t need to lift the surface. We open a small access pit at each end (typically 600mm × 600mm) — your block paving, gravel, lawn or tarmac in between stays untouched.
Yes. We pull a new WRAS-approved blue MDPE pipe through, isolate and cap the old lead supply, and ensure your new pipe is bonded and tested before going live. The old lead is removed safely.
