Onto the garden. A half brick to be precise... No cracks on the chimney that I can see, can see where the brick came from and 2 or 3 of the others look 'weathered' but not quite ready to give up the ghost. House is 1950s ex-council and passed the buying survey 3yrs ago. Am I foolish to just leave well alone? Or when the chimney falls through the roof will the repairing builder tsk at me and wonder why I didnt act now?
