    What we do

    Specialist moling & full-service plumbing

    One trusted local team for everything from hidden leaks to complete bathroom installations.

    Our specialism

    Replace your water main — without digging up the garden.

    Moling is a trenchless technique that uses a pneumatic mole to bore a tunnel between two small access pits and pull a new MDPE pipe through. Less mess, less disruption, lower reinstatement costs.

      An air-driven mole bores a clean tunnel and pulls the new MDPE pipe through.

    Grange Plumbing fitted our new bathroom from start to finish. The work was immaculate and they kept everything tidy throughout. Couldn't recommend them enough.

    Called them about a leak under the drive. Used moling so no trenches dug — finished in a day and the lawn was untouched. Honest, fair pricing.

    Had moling done to replace our old water main. No mess in the garden, finished in a day. Far better than the trench quotes we had from others.

    Pinpointed a hidden leak under the kitchen floor that two other plumbers couldn't find. Quick, clean and reasonable. Top marks.

    Replaced our supply pipe from the boundary to the house using moling. Driveway and garden completely undisturbed. Brilliant work.

    Professional, punctual and tidy. Sorted a stubborn dripping tap and fixed our outdoor tap the same visit. Will definitely call again.
