Rewiring around cornicing, panelling and original joinery.
This is the part that worries people most, and rightly. The features are why the house is worth what it is worth, and a careless rewire destroys in a fortnight what took a century to acquire. The answer is that the cable routes are planned around the features before anything is opened up.
- Cornicing and ceiling roses. Wherever the floor layout allows, cables drop from the joist void above rather than being chased through a decorated ceiling from below. Lifting boards upstairs is almost always better than cutting plaster downstairs.
- Lath and plaster. It is brittle and it fails in sheets rather than neat holes. Fixings, back box choice and where a cable can be pulled are all different from modern plasterboard, and treating it like plasterboard is how ceilings come down.
- Panelling, shutters, dado and picture rails, deep original skirtings. These are exactly what an inexperienced installer cuts straight through. Lifting and refitting a section of skirting, or routing behind it, is slower and is the right answer.
- Floors and doors. Boards are lifted to a protocol, numbered, and refitted with screws rather than nails. Parquet and original boards get planned around, not through.
- Where surface containment is honest. In cellars, attics, garages and outbuildings, a neat surface run beats butchering historic plaster to hide a cable nobody will ever see.
And the thing nobody puts in writing: we fill and bond the chases we make and leave them ready, but we are electricians rather than plasterers. At quote stage we tell you exactly what making good is included and what your plasterer and decorator pick up. That conversation before the job is far better than the same conversation after it.
