hi fellas
You are probably quicker than me, as i cant see me doing 30 windows in an hour and a half...
Maybe with a wfp some guys could do this in that time, but trad (up and down ladders) would defo take me longer, especially the first one which as you guys say will take longer.
Im still thinking of around £45.00 and a bit more for first clean which will include cleaning down all the pvc..
Thanks chaps for your input
