Here at Lethenty Mill, I have 45 windows, of which I have now restored 35. I only counted them the other day in desperation! These are old windows, many of them from before my time, and I have patched most of them before (about 20 years ago). Nobody seems to speak about this task now and in our neck of the woods (North East of Scotland) tradesmen are not enthusiastic about taking this work on - even if I was able to afford it! It involves removing rotten sills, repairing frames and rebuilding sashes before you even start painting. I have to admit that I haven't spent enough time on regular painting and now my sins have found me out! Does anyone else have any thoughts or experiences on this subject that they would like to share?
