Came back from holiday to find several small piles of whitish powder on the wooden floorboards in corner of kitchen.
(I can't post photo as don't know how to).
I wiped them away and within a week they are back.
These are distinct piles of dust, NOT fine layer of dust and definitely not rust red.
I have had a preservation company guy round who prodded the floorboards and skirting with a damp meter and said there's no evidence of dampness.
The distinct piles of dust are only in this corner on about four floorboards and there is no musty or bad smell.
Any thoughts please.....
