Agree with the blue one, you shouldn't have washed them inclusive of clearing, price as separate jobs, usually around the same amount, unless your doing gable ends as well, then the wash is more, you can then pitch a combined wash and clear together at say 10% off.
None of these guards or brushes work, had a few where like smurfs picture shows they become part of the problem.
I never price per meter, price for the job, gutter style ( square, round, o-gee ) ground access and of course a premium if over conservatory or extension.
Regular customers are priced the same as 1 off's - people will either pay it or not, never lost a window clean job because they didn't want to pay for a gutter clear - if people sign up for a yearly gutter inspection clear then the price is reduced because they only take half the time of full gutters
