If you need a check if the 900-year-old spire of Norwich Cathedral needs a spot of restoration or some repairs, you need to send someone up there to check it.
Or in this case it's a pair of steeplejacks with a head for heights that runs in the family - father and son, Chris and Sam Milford
At 315 feet or 96 metres, Norwich Cathedral is the second tallest in England after Salisbury.
It's forty years since the last repair project at Norwich Cathedral but this time there is no need for scaffolding.
Chris and Sam are not only great climbers they have the masonry skills to replace damaged stonework and fill in failed mortar. They're also hoping to remove the gold cockerel weather vane for re-gilding.
Work began constructing Norwich Cathedral in Norman times in 1096 and it took nearly 50 years to complete.
Maintaining Norfolk's finest building has always been a labour of love. In the 1960s death watch beetle had taken its toll.
