I have just pulled this thread back up because of a young lad I saw working yesterday. He pulled up in a sighwritten van two doors down from me after I had started, he was gone before I had finished.
I wouldn't have said it was his van.
His brush literally did not touch the entire surface of the glass. Where it did touch it only got done once. Didn't do the frames or the sills. Well, not properly in my opinion. Yet interestingly he rinsed well
You really don't have to worry about these people, they will always be there and they appear to be getting away with it.
