These are my least favourite windows to do and normally don't bother with the hassle of moving the ladders so much as you can't reach the top of the window with the ladder on the sill. ... But I got a call today of the son of a lady's I already do, I didn't turn it down because I know it's gonna be a good price as hers is £14 for a dorma bungalow and the house I'm doing tomorrow is a large detached. How does everyone else do these windows?? I've seen window cleaners rest the ladder on the frame half way up but I'm not keen... Anyone else have any ideas?
