I am about to close on a new house that was completed in July. On outside walls, I notice there are substantial number of bricks that have small cracks. In a couple places, the line cracks run through a few bricks. This is my first house and I do not know if I should be concerned over this and where I can turn for help. I have attached two photos. One shows the cracks on an individual brick and the other shows the connected cracks through a few bricks. Any advice is deeply appreciated.
