What is best for sealing around cables into the loft please? In particular, is there a non-setting sealant?
I ask as I am replacing some lighting cable. I know I need to make a good seal around cables to guard against condensation in the loft. Some sites recommend silicone sealant. While that has worked so far it seems to me it will make life hard if future work is needed - eg on changing light fittings. So I've looked around for the electrical equivalent of Boss White or Dum Dum without success so far.
