Regarding stonework that has naturally aged (changed colour), is still soot blackened, like on period houses. Of which some would say is part of the character of old houses.
Does, or will, the run of soapy water down the sills etc from wfp alter the stone's 'patina' by basically cleaning it. Something that maybe not evident on the first clean, but after 3 years...?
Just wondering as i am part-time traditional and wondering if there might always be a market for traditional in this way.
maybe something that time will tell
and something perhaps for prospective ladder legislation to take account of.

Comment: Its worth considering that a lot of modern ingenuity doesn't actually take into the account the nuances of intricate things. Like stone cleaning damages the stones natural 'crust' leading to erosion, uPVC windows look sh!te on period property, because, for a start, the proportions are wrong, etc etc...
