"Traditional pipe replacement companies WANT to dig trenches — because they charge you by the metre for excavation AND reinstatement. We've eliminated that entire cost with technology they refuse to invest in."
If you're dealing with any of these frustrations, you're not alone. These are the exact problems our clients come to us with every day.
Homeowners needing supply pipe replacement without excavation
Property managers wanting minimal disruption to tenants
Commercial properties needing pipe renewal with zero downtime
Listed buildings or properties with sensitive landscaping
Developers needing efficient pipe infrastructure upgrades
Internal plumbing work (we specialise in external pipes)
Boiler or heating system problems
Gas pipe work (we handle water systems only)
Drain and sewer work
Survey & Planning
We survey your existing pipe route using the latest technologies, planning the optimal approach for trenchless replacement.
Trenchless Installation
Using moling, pipe bursting, or slip-lining techniques, we replace or renew your main pipes from entry and exit points only — no trenches required.
We pressure test the new installation, verify flow rates, and hand over with full documentation and warranty.
We use pipe bursting, slip-lining, moling, and CIPP lining — choosing the optimal technique for each situation. Two small access points replace hundreds of metres of open trench.
From dreading a month-long excavation nightmare to having brand-new pipes installed in 1-2 days with your property looking exactly as it did before.
Trenchless pipe replacement uses specialist 'no-dig' techniques to replace or renew underground pipes without excavating a trench along the full pipe run. We only need small entry and exit pits, preserving your garden, driveway, and landscaping.
Trenchless methods typically save 30-60% compared to traditional excavation when you factor in reinstatement costs for driveways, paths, and landscaping. The savings are even greater for longer pipe runs.
We use pipe bursting (replacing old pipe with new), slip-lining (inserting new pipe inside old), moling (creating new routes), and CIPP lining (curing a new pipe inside the existing one) or excavation.We choose the best method for each situation.
Most residential jobs are completed in 1-2 days. There's no waiting for trench backfilling or surface reinstatement because we don't dig trenches. Your property is fully usable throughout.
We use trenchless methods wherever possible to minimise disruption. When excavation is needed, we restore the area to its original condition as part of our service.
That's the whole point — in most cases it won't. We only need small access points at each end of the pipe run. Your driveway, garden, paths, and landscaping remain untouched.
Yes, this is one of the biggest advantages of trenchless technology. We can replace pipes that run under driveways, walls, and other structures that would be impossible or very expensive to excavate.
