on a more affluent part of my work a few have moved out and not been replaced and i have lost £200 a month through it and its hard to replace as they are behind locked gates and not easy to get at etc
Also , you arent the only cleaners to think , lets target the big houses , they get hammered by leaflets and canvassers , its good as has been said to target this stuff as a nice part of your work , but like commercial etc i find its just another string to the bow and dont get to caught up trying to get rid of all lower priced work as hourly rate is all the same ....
I find the bigger stuff needs more managing too , ringing ahead , not today etc etc and you end up putting up with it because its £60 a month or whatever
unless you live on top of this kind of work , its not the answer to all your problems
