And your feckless decorator were to trash the edges of your new carpet by piping corking along them, what do you do next ?
As far as I can see we need to get the carpet lifted, fit skirting then relay the carpet with the edges trimmed off.
Are there other options for neatening up the join from stair carpet to wall? ( walls needed lining paper so any join was always going to be a bit tricky).
What options are there for stair skirting?
