Our battle with the dreaded worm is hopefully over. Rentokil have now successfully treated the Mill tower and will issue a 30 year guarantee for the work completed. I am now a woodworm expert after spending so much time with the Rentokil guys, not sure that this is a good thing as I seem to be obsessing about every pile of dust I see , which isnt good in a windmill of this age. Plenty of dust to look at! With our guarantee in place we are now set for the next 30 years !
