Just had a call from a lady wanting a one-off conservatory clean. Windows and PVC but not the roof. She would like it done ideally before xmas as she has family round. I wasn't going to be working tomorrow but as it's a one-off urgent clean I'm seeing pound notes... A nice little bonus. Before I ask for a price the obvious question is: "What's a conservatory?" But what sort of figure would you have in mind? Hourly rate, 1.5x hourly rate, 2x?
