Working in Llantwit Major
We work right across Llantwit Major — CF61 — and in neighbouring Bridgend and Barry.
Llantwit Major gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Llantwit Major 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. Whether your Llantwit Major bathroom needs a refresh or a full strip back to brick, the written quote shows both where both are realistic.
Most of South Glamorgan has moderately hard water. 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
- Tiling, fitting of the suite and furniture, making good and decorating, then handover
- Layout changes such as moved doors, new stud walls or boxing for concealed cisterns
- New hot and cold pipework and wastes, with isolation valves to each fitting
- New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
Decisions to make first
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.
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.
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.
