Im a newbie window cleaner and have just been round to quote windows on a very large new build, aprox 50 windows inside and out! was also asked if i could clean 4 good sized bathrooms and kitchen aswell as cleaning tiled floors all through down stairs and skirting boards and door frames. dont know how long this is going to take me. So going to charge by the hour, any ideas on what i should charge as an hourly rate? I live in Lincolnshire. Cheers Hayley.
