Exterior property decoration

[andyandclare]

We were hoping someone else has experienced this problem and can offer some advice.
We have owned our property since 2007 and it is now well overdue for a lick of paint to the outside. The property is a 3 storey duplex and we own the top 2 floors, with our neighbours owning the ground floor apartment.
 Here is where the problem lies, we have approached our neighbours with 2 quotations to decorate the whole block in one go, but our emails remain ignored.
 It makes sense to decorate all in one go 1.To reduce the cost & 2. To prevent the paint/colour fading if decorated at different times.
Any advice on where we go from here would be appreciated.

Andy some people are not good with e-mail and often do not regularly check their mail, and in many cases change their e-mail address as they are cut off for non usage by their provider.  Which is a long winded way of saying they may not be ignoring your mails, so can I suggest that you try to contact them through some other means.  Hopefully you'll then get an answer, or even better the right answer to paint the villa.
