Questions about ensuite installation in Monmouthshire
Can an ensuite go anywhere?
It needs a route for waste water. Gravity drainage is best; where that is not possible, a macerator or pump can work. We check at the survey.
How noisy are macerators?
Modern units are quieter than older ones but still audible. We use them only where gravity drainage is not possible and fit them to reduce noise.
Do you carry out ensuite installation across Monmouthshire?
Yes, across the whole of Monmouthshire, including Brynmawr, Abergavenny.
