Bricks, Masonry, Asphalt and Concrete - Cracked exterior brick

I have an approximately 50 year-old brick house. I notice that all around the house there are small cracks in the bricks. I do not believe the cracks are a problem overall, but I do not like the looks of the cracks. Also, on some of the bricks there are some brown spots. Is there anything I can do to correct the cracking problem/spot problem? I have heard that you can replace the brick, but more than just a few bricks are affected. I was told to powerwash/seal the brick---but what about the cracks? I love the house. If anyone has any advice, I would greatly appreciate it---thanks in advance!! : )

The only solution to the cracked brick are like you were told cut them out and have them replaced.

If brown spots will come off with power washing, and there are enough of them to warrant this, then have cracked brick replaced then wait for them to set and then power wash the whole job.

Thanks for the information; does anyone know if replacing the cracked bricks is something I should hire someone for? Thanks! : )

yes you need someone who can cut out the brick using a power saw with masonry blade, and someone who can re install brick with mortar, this dose not have to be a bricklayer, but he will have the tools to do the job.
