I have absolutely no hesitation in whole heartedly recommending The Sash Doctor. Les has done a magnificent job on our sash windows, our house is grade II listed so we needed an expert. And we found one. Our windows were in a sorry state, many wouldn’t open after years of neglect, they were draughty, they rattled and several were rotten, but since he has completed a full restoration they look like new windows. In fact they are no doubt better than when they were fitted, we have no more draughts.
