i try to prolong the initial conver, to find out what it is they really want. oh course they want the windows cleaned thats a given, but what of the future.
another thing i now do is when going to do the 1st clean i say "im coming monday,have a look at your windows ,give price SEE IF ITS A GO-ER "
when i get there any sign of bother ,dog plop garden,a connie "wed like that cleaning every 3 or 4 cleans instead of upstairs windows " "spiders eggs need removing from in by the hinges " or other nonsense
i say im sorry its not suitable for my ladders you need one of the water pole guys . asap i block them on my phone and on facebook hopefully before they leave a sh/tty review
