Working in Merthyr Tydfil
As well as Merthyr Tydfil itself (CF47 and CF48), we survey in Aberdare, Rhondda and Ebbw Vale.
In Merthyr Tydfil, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. A renovation survey in Merthyr Tydfil looks behind the surfaces, at joists, pipework and wiring, before any figure is put on paper. For listed and period properties in Merthyr Tydfil, we check early whether listed building consent applies to the work you have in mind.
Supplies across most of Mid Glamorgan are soft. That leaves you free to choose matt black, brushed brass or clear glass without worrying much about limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- New hot and cold pipework and wastes, with isolation valves to each fitting
- Tiling, fitting of the suite and furniture, making good and decorating, then handover
- New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
Decisions to make first
Pipe material
Copper suits exposed runs and the area near the boiler. Plastic pipe is quicker under floors and inside walls, and long runs need fewer joints.
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.
