Why is everyone scared to put in a high price for jobs like these.....there georgian...there a pain in the arse trad or not...more so trad,,but still a pain.
Id go round with the woman comment on how lovely her house is how beautiful her garden looks. Tell her how glad you are that she contacted you cos she obviously takes pride in her home and garden etc and you take pride in your work of cleaning windows, let her know that you are reliable and friendly and any one that works for you takes the same pride in there work and are equally as respectable and friendly.
Ask her,,,Have you cleaned them yourself before cos if she has she will know how difficult they are to clean and she wont then expect us to do it for peanuts.
Id then charge £60-£80 depending on a few more factors eg distance.
Look for her reaction and its not difficult to read what shes thinking. Remember you can always come down in price but never go up..... if she says 'great thats fantastic, i thought it would be alot more than that'.... then you got the price wrong.
If she umms and arrrs and cringes her face slightly and says...'ooooh its a bit pricey...but...i really need them doing..... ok then.' Then your bang on!
So what if she hits the roof and says no.... wait for her to calm down and explain why...and if she still says no then ask her what price would she be happy with youll be amazed at how little they will drop the price...most of the time alot less than if u dropped it cos you feel bad and are desperate.
Its happened to me loads.
And now i never just put a note through the door with a quote..i will always arrange to see them in person. The chance of you getting the job increases massively.
