Dont worry, i am not going to get started on best removal and application methods etc. Basically, i am too impatient, and rubbish at the task from start to finish, and so i am going to get someone else to do it, better than i ever could. I have been quoted £50 for a tiled shower enclosure with tray. Does this sound ok price wise? (to me it seems good for something i hat/cannot do). The sealant is not in shocking condition, but has just started to part company and so discolour with the tray.
