# M Thomas Water Services Ltd

M Thomas Water Services is a family-run water engineering company based in Cardiff, serving domestic and commercial clients across South Wales. As Welsh Water-approved qualified engineers and members of the Water Industry Approved Ground Worker Scheme (WIAPS), they specialise in trenchless water pipe replacement and repair solutions.

The company distinguishes itself through advanced moling technology that replaces and repairs water pipes of all diameters—from large commercial mains to small domestic feeds—without extensive excavation. Their pneumatic moling units navigate beneath driveways, lawns and patios, eliminating surface disruption that traditional methods require. This makes them particularly valuable for lead pipe replacement projects where property preservation is essential.

M Thomas Water Services addresses the full spectrum of water infrastructure challenges. They locate and repair leaks, replace aging water mains, handle common supply work, and provide both domestic and commercial moling services. Their expertise spans residential properties through to large-scale commercial installations, offering customers a single qualified point of contact for complex water engineering problems.

What sets them apart is their commitment to cutting-edge technology combined with professional service standards. Rather than defaulting to disruptive digging, they prioritise minimally invasive solutions that protect customers' properties whilst delivering reliable, long-term fixes. This approach, combined with their Welsh Water approval and WIAPS membership, positions them as trusted specialists in water services across South Wales.
