Had a message on face book from a young lady asking am I a window cleaner,to that I replied yes,and this was the response. Great thanks. When r u free? I would like a one off of windows and sills etc If that ok? And then windows cleaned every 6 weeks or so through the summer? Now I'm not a fan of one offcleans,and this is the first time I have been asked for summer cleans. I'm not being proud or pig headed,as that's why I'm asking peoples opinions before I text back. But let's face it,I'm going to use my UBIK and time scrubbing them frames up,then next summer she will call me again to do same. What should I do?
