When M Thomas Water Services replaced my lead water pipe, I was expecting lots of disruption and mud. Unbelievely it was a painless experience. It was all completed in no time at all using what they referred to as 'trenchless technology'. The whole thing was over in no time and I have had absolutly no issues since. I would highly recommend them. - Geraint Jones (Penarth)
