Working in Blackwood
In Blackwood we cover NP12; we also cover Gelligaer, 2.1 miles away, and Risca.
Being a smaller town does not change how we work in Blackwood: free survey, written quote, one team. If your Blackwood home is older and the bathroom still has original pipework or plaster behind the tiles, the survey shows whether a renovation or a refit makes more sense. For listed and period properties in Blackwood, we check early whether listed building consent applies to the work you have in mind.
Supplies across Gwent range from soft to hard depending on the source. 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
- Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
- Layout changes such as moved doors, new stud walls or boxing for concealed cisterns
- New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
- A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
Decisions to make first
How far back to strip
Back to brick gives a clean start. Keeping sound plaster on some walls saves time and money, and the survey shows which walls can stay.
Plaster or boards
Plaster suits dry walls that will be painted. Cement-based tile backer boards are the better base behind showers and under heavy tiles.
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.
