with u ron!!!! im sure if someone came in to clean ya house and it was a pigsty n they took longer to get it clean theyd charge more then go to a rduced rate on a regular clean
sometimes i double it on really big houses, smaller ones i might add a bit, sometimes not at all, depends how busy i am, how much i want the job, where it is, whether i think the custy will be okay with it etc etc, but i wont stop because some dude on a forum says so

and since when do you have to clean all frames etc when window cleaning?? otherwise why aould upvc cleaning exist??
if they wanted that i would price it seperate......why stop at frames, clean there bricks, fascias and soffits, and toilets too, bet you will get loads of recommendations then....
