Working in Llanelli
We cover every part of Llanelli, including SA15, and nearby Gorseinon (5.2 miles) and Swansea (10.3 miles).
In Llanelli, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Llanelli 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. If you have just bought a house in Llanelli, renovating the bathroom before moving in saves living through the dust.
Water across much of Dyfed is 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
- A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
- Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
- Repairs to rotten floorboards, joists or other timber found once the room is open
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.
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.
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.
