Moved to our house 2.5 years ago, one wedding and 2 babies later I still haven't got round to engaging a window cleaner.
DH has done it once I think, I've cleaned them a little from what I can reach from the inside. They don't look very dirty at all considering!
However I would like to engage a window cleaner but money is tight. Can you just ask them to come round as a one off? I was thinking they probably only need doing several times a year. My parents get theirs done once every 6 weeks but they have lots of trees around their house and are forever getting bird poo on their windows. I don't think we've ever had any! Thoughts?
