Oxburgh without scaffolding - or is it?

We got rid of the scaffolding outside but when I arrived today there was the scaffolding tower in the saloon! (see extra)
The ceiling is so high they need it to clean the  coving and this week textile experts are also coming to examine the pelmets and the very old curtains which are a feature of this room but are affected adversely by the light from the south-facing windows. We are on winter opening so the house is only open Thursday - Sunday,  making it easier to carry  out this sort of work.
