It is mate to be fair,some of my first cleans have been very messy and taken a fair bit of time and I had wished I had charged more and I might have gotten it but the view I have taken is that after the first clean-esp frames etc,when you go regularly every 2 to 4 weeks the clean is a lot quicker so look at it long term,plus I havent had anyone sack me after a first clean(or ever yet) so at the minute am not worrying about charging more.
Whether I am right is debatable,we are here to clean and make a living so I could be missing out on increased earnings but would rather miss out on a couple of extra quid and have a job long term than get turned down over a first clean price.
the 2 to 4 weeks cycle to cleaning is important to me though,longer than that and I find the frames and windows get pretty dirty so you are losing time cleaning them up to standard again,I find over 4 weeks and its getting towards a first clean scenario,if someone wanted a clean on a basis longer than 4 weeks I would be thinking of charging a bit more then.We have a family friend who has a big country house with georgian windows that has not been cleaned in a while,plus she has mentioned an 8 week period between cleaans which I am worrying about as I feel that is going to make it a long job every time,am going to do the clean and talk to her and try to persuade her to get them done more regularly otherwise it will get dropped when my round fills up but its useful now as I have not got a full round and itll be good experience.
