I dont know why this is such a problem. It seems getting the balconies done which are causing concern so Trevor has the right idea - read his thread and the important bit
- If, when we arrive, they are in, we knock and clean the balcony windows. If they are out, TOUGH!
Its the managed compromise between getting the overall job done, safety and cost. Any other solution is just hedging the ecomics of the job.
A no brainer!
