Working in Blackwood
We work right across Blackwood — NP12 — and in neighbouring Gelligaer and Risca.
Being a smaller town does not change how we work in Blackwood: free survey, written quote, one team. If your Blackwood cloakroom has no window, we size and duct the extractor fan so the room clears properly. We survey cloakrooms in Blackwood with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly.
Hardness differs from one part of Gwent to the next. Taps and wastes will need an occasional descale, and chrome or brushed finishes are easier to keep clean than polished brass. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
- A concealed cistern frame or WC unit where the space allows
- Strip-out of the old fittings, waste removal and making good on the hall side
- Splashback or feature tiling and a new floor, often LVT or porcelain
Decisions to make first
Under-stair layout
Headroom drops quickly under stairs. The basin and the space in front of the WC need standing height; the low end of the room can take the cistern or storage.
WC style
A wall-hung WC on a frame gives the most floor space and looks neat. A back-to-wall pan in a short furniture unit is easier to fit against an uneven wall.
Rules that apply in Wales
In Wales, Part H covers a new drainage connection and the Welsh Part F covers ventilation, with rates similar to England. The Welsh Part P has a wider notifiable list, so check with your electrician whether the cloakroom lighting and fan need to be notified.
