Working in Caerphilly
We work right across Caerphilly — CF15 and CF83 — and in neighbouring Risca and Pontypridd.
Homes in and around Caerphilly vary, so we look at the floor, the walls and the water system before we price anything. If the only toilet in your Caerphilly home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips. If you are refreshing a dated cloakroom in Caerphilly, a wall-hung WC and slim vanity can change the room in a few days.
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
- A concealed cistern frame or WC unit where the space allows
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- Splashback or feature tiling and a new floor, often LVT or porcelain
- Strip-out of the old fittings, waste removal and making good on the hall side
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.
Door
An outward-opening door is usually needed so it does not hit the WC. A sliding door suits a narrow hallway where an outward door would block the way.
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.
