Being a smaller town does not change how we work in Dumbarton: free survey, written quote, one team. For listed and period properties in Dumbarton, we check early whether listed building consent applies to the work you have in mind. In Dumbarton flats, the title deeds and the flat below are considered before a renovation is planned, particularly for moving the WC or adding a vent.
Supplies across most of Greater Glasgow 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
- Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
- New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
- Layout changes such as moved doors, new stud walls or boxing for concealed cisterns
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 Scotland
In Scotland, structural work, altering drainage or forming a new bathroom may need a building warrant, which must be granted before that work starts. A straight refit rarely needs one. Electrical work is tested and certified to BS 7671.
