ya its depends, some buildings made out of clay or ceramic will crack split and turn to powder, wood ones can rot and crack and plastic ones usually just fade and glue wares out. our sets over 10 years old and every so often a brige gets removed , houses gets moved around every so often and stuff changed.



the biggest issues tend to be critters wild, or our black lab/ greyhound mix bella lol, and usually hind wind is another issue
