Thanks guys , for that input , my question , was as i soon found out was based on my first close up with cast guttering, and as it turned out , that guttering was diferent to most, in that there wasnt a nut and bold holding the lengths together . There was a tapped bottom bit , so my question of weather anyone drilled out the rusted in bols , prob doesnt realy apply to most .
I found a sealant that can be used in wet conditions , seemed to work ok , time will tell.
Ihad another prob, the customer enquired about my public liability , Yep " got a million pounds worth" , ..but in windowcleaning ..mmmmm he was a stickler for it being right , and , ive yet to resolve this. Anyone else have apropriate insurance ?
