Depends Commercials it may be included on my Residential it is never included how do I know how long fall is going to take when its April or May and I am doing the estimate. I also give them the option not to have a clean up when you get busy your understand why I never finish all my cleans up any way just to much work and it always snows 1-2 weeks too soon.
I have heard of companies requiring clean-ups for all their clients and charging them an hourly fee.
I am aware of companies that mow their lawns weekly even after the lawns quit growing and either mulch or bag the leaves till they have all fallen. They charge the same as a mow.
I personally make my clients aware I do leaf clean-ups and have them contact me if they are interested and it is an extra charge.
I think what you have demonstrated is something I have felt for many years here. Which is the threads 10 years ago were better they were more lively and often about business related topics that get no mention at all now.
