I spend every day huffing and puffing over the results of my window cleans, never happy, never getting the perfect house and certainly never getting a quality first clean.
Yet every day more and nore work pours in, nearly all by recommendation. "you do such a brilliant job that I phoned my daughter up and told her to cancel her cleaner!"
(turned that one down - too far away).
I think they must be more impressed with the frames than the glass sometimes 'cos i'm never impressed.
