Working in Caerphilly
As well as Caerphilly itself (CF15 and CF83), we survey in Risca, Pontypridd and Gelligaer.
Homes in and around Caerphilly vary, so we look at the floor, the walls and the water system before we price anything. A renovation survey in Caerphilly looks behind the surfaces, at joists, pipework and wiring, before any figure is put on paper. For listed and period properties in Caerphilly, we check early whether listed building consent applies to the work you have in mind.
Hardness differs from one part of Gwent to the next. Easy-clean glass and good-quality brassware are money well spent. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Repairs to rotten floorboards, joists or other timber found once the room is open
- Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
- A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
- Layout changes such as moved doors, new stud walls or boxing for concealed cisterns
Decisions to make first
Combining rooms
Taking out the wall between a bathroom and a separate WC gives one larger room, but it is structural work and may need building control.
Heating
Moving the radiator, adding a heated towel rail or laying underfloor heating is simpler while the room is stripped.
Rules that apply in Wales
Wales applies its own building regulations, including a wider Part P and its own Parts F and H. Structural and drainage changes go through building control in much the same way as in England.
