Hello jplaya517 and welcome to the Community.
Often a stair-stepping crack in the veneer of the brick is usually sign that the foundation is compromised and the house is settling.
Other signs of foundation problem from settling are cracks in the interior walls, sticking doors and windows.
Accurately measure the distance between the actual blocks to determine if the crack is simply mortar aging or if there is actually a shift in position of the blocks or bricks.
If there is rapid change in the cracks then this means that the house is currently and actively moving and getting to the root cause becomes more urgent.
When a foundation is compromised, carefully inspect the top story of your home from the outside using a ladder. Look for cracks that appear above window frames – this is the most common place for damage to become visible.
If your foundation is compromised it is important to fix the root problem. This is not usually a DIY project and you should contact a professional foundation specialist to evaluate your situation.
I would get several quotes. Make sure you get detail explanation exactly what is the cause and how they plan on repairing.
Thank you for your inquiry.
Hello again jplaya517,
You could repair the cracks with mortar repair products that are available in caulk tube form or a dry power that would require mixing. Rapid Set is mortar mix is very good for repairs. If after repairing the mortar it stays secure and does not continue to crack you are in good shape. But if you have new cracking and separation that is when you may have to contact a professional for help.
Sometimes garage floor slabs are poured separately or not as thick and have a tendency to shift. The problem still needs to be address.
I hope the simple repair will work for you.
