The nickel and dime comment from Paul is spot on.  I've been sent letters and charged for cleaning siding twice and the work was done and a message left for Kuester with no return call.  I have neighbors with terrible looking yards, dirty siding, and others but they never receive a notice so this is personal for some reason.  I've always paid my dues in advance and also cut grass for a vacant house beside me regularly but they still nickel and dime.  If you have a choice STAY AWAY!  Oh yea I even took proof into show the siding was cleaned with a date stamp on the cleaning and nothing was done!
