COST

Without seeing the property this is really difficult to estimate, but these are the things that are taken into consideration.

•    Hire and erection of scaffolding - required for health and safety
•    Size of area for pargeting  
•    Preparation of surfaces
•    Cost of materials
•    Intricacy of pargeting required
•    Travelling distance and time

A relatively straight forward job, for example a small house front with two panels, could be as little as three days work.  Renovating the front of a listed building could take a month.
