Am in the process of swapping to wfp and i am looking at every house with a view to doing them all wfp and where the best place is to park the van ect to make it all run like a well oiled machine, but there are some windows that are going to be a pain to do with with wfp namely balcony windows, windows over a flat roof, and upstais french doors with railings infront of them. So d you do these window trad, leave them or is there a special way that i will be able to get to them with my pole?
