:? I am about to move into a new bungalow, but have a query about the sealant around my window frame. There is mould growing on the sealant, and I have the sealant itself, but do I need to take the mouldy sealant off or do I leave it on and put the new stuff on over the top?[size=18][/size]
If there is space to add more sealant, treat the existing with neat chlorine, wash and dry, apply another layer on top.
Or, cut out a wedge of the existing sealant to remove the mouldy bits and apply fresh sealant.
