£200  FFS haha. Joke and plss take.

I would have told her no problem, £200 because they have not been cleaned since I last cleaned them. Money paid into my bank account before I begin. I always offer old customers my service back but bump up the price. I'm happy to do work at a premium. Received a call from a rich guy saying he only had 12 windows. He texted his address and I saw it was a £750k house. I text back the real price and not heard from him since. I think he bumped the windy cleaner and thought he would get a newbi to do it for a tenner a month or he was selling up. Great getting customers this time of year because we are all busy so give a good price and don't need to explain anything because they need you more than we need them.

I'm cleaning 4 of her neighbours this morning so I'll smile and wave at her if I see her!

She basically replaced me with a cheaper cleaner who charged £25 but the skylights will not have been cleaned for 3 years now as they don't have a 47ft pole!🤣

If you’re responsible for that persons work you MUST inspect their work, it’s basic management.
Once you’ve gained confidence in them,  you don’t  have to be so dilligent.

you can use hypo on tarmac.
I think somewhere someone once said you cant - to be honest its not down long enough to cause an issue
