Every body is going to loose a customer at some point, I havnt yet and it wont be over using the wfp, it will be because there moving house or something, I wouldnt even consider using trad method on the outside of houses it takes to long and thats not because im a newbie my mate has been cleaning windows for 16 years and we did a time challenge on my house, I beat him by 4 mins, times that over a year and thats a lot of money. Like I said in my last post eventually trad will have to change to wfp.
