I have a single-family home with brick all around. The home was built in the early 80s. Some of the mortar is starting to crack here and there. I had a tuckpointer come and give me an estimate on repairing it, and he told me something interesting. He said if a horizontal crack is as long as the brick itself, that brick needs to be removed and reset because most likely, the mortar between the brick and its neighbor is most likely broken as well and needs to be replaced. The cracks I have are very thin, they're just long (nearly the length of a brick).
Is what he said true? Thanks,
