I clean 8 weekly and I use Aworka to organise my round. Thank you to Chris (who runs it) I think he is exceptionally good and very helpful. I am a one man band and it works well for me.
I try to clean 4 days per week and leave a day for rain. I do clean in light rain but not the heavy stuff (can't be bothered). Unfortunately I get a bit busy and put in a fifth day, or work Saturdays doing gutter/fascia jobs etc. I don't mind this because the alternative is shopping with Mrs Window Cleaner at Sainsburys. (A double negative in my book).
I plan my days so all the cleans are in one place (same street or never more than a street away). It's compact and it works for me. Unfortunately I also have some 4 weekly and 12 weekly work which I took on when I first started and now wish I had not. It's well paid (but only if you're in the area). I'm now finding anything other than 8 weeks to be a PIA.
In Aworka, I use the Monday-Friday section to organise my 8 weekly round.
Sunday (which is the first column: start of the week) I use to put in all my work that is not 8 weekly. So every week I have four days of planned and scheduled work (plus one day for rain). Plus the 'Sunday' column with all my work that is 4 or 12 weeks that I need to fit in somewhere during the week. The problem is I am busy during the week and can't always fit it in. So I end up on a Friday running around fitting in the extra work. I don't want to bin it, because it's well paid, but I don't want to keep it because its a PIA. (Any suggestions here would be good).
Daily: I text or phone every customer the day before I clean. Where I am, most custies have locked gates and I am 52 with (not very good bones, according to my dietician), so I don't really want to fall off...anything!
Now for me this texting and phoning actually works; after 8 weeks most want their windows cleaned. If they are in...great. 99% will leave their gate open and some money out, or pay online, if I leave them a slip. The ones that forget, or are on holiday (I clean the fronts only and charge half price, they all know that). I think that's fair and reasonable. I've never lost a customer doing this. Most are apologetic and it rarely happens again. If it happens more than twice they are history. To counteract any potential loss in revenue during the day I tend to over subscribe my work. So if I want £200 a day, I will contact £230 to allow for people on holidays etc.
However, I am still back to the 4 and 12 weekly work. I will either have to change them to 8 weekly, or get more work so I can bin them.
That's a shame
