first clean and additional cleans on a construction site you do need a cis card if your building firm have windows cleaned after the CML then you dont
easy clean there are a few points that confuse me about your post
ive just got a 2 year contract to clean every new house for one of the biggest housing developers in this country...and 500 of them a month @ £15.00 each.....
your going to travel from lands end to john o groats to clean windows
??
i work for the countrys biggest house builder the one with the oak leaf but only work in the north westand yes befor payment you need a cis card the most that 2 men can clean in a day is 10 first cleans how the hell are you going to do 500 in a month with all that traveling and knowing building sites as i do most completions are at the end of every month so you would end up doing 500 in 2 weeks also there are some dirty sites and say 25 to 50 %will need a reclean thats up to 750 houses in 2 to 4 weeks
on the sites that i work on there are possibly 7 diffrent styles of house all diffrent windows my smallest is quite a bit more than yours if you want to come and work for me i will give you £15 cash and no cis card
