Worry about the woodwork? (4)
I believe the answer is:
fret
'worry about the woodwork?' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for fret that I've seen before include "Worry - bar on the fingerboard of a stringed instrument" , "Worry; sort of saw" , "Worry excessively" , "Fog" , "Worry; wet mist" .)
