   Not sure, I have no interest in having other people do things to my house, I   
   do DIY.   
      
   I assume the answer to your question is "sometimes", based on what's been done   
   to other houses previously.  If it's double brick, they pump in stuff through   
   drilled holes.  If it's single brick, they attach foam sheets then put   
   pebbledash over it.   
      
   My house is double brick with just an air gap.  R of 6 is enough for me.
