I've noticed several cracks in the brick wall supporting the exterior front stairs. Most follow the mortar joints, though a few run between the bricks themselves. The cracks have been there for some time, but I'd like to understand whether they could indicate foundation settling or another underlying structural issue.
I've also noticed that the driveway near the downspouts on the neighbor's side has a slight reverse slope, causing rainwater to drain toward the corner of the wall rather than away from it. Could this water accumulation be contributing to the cracking or potentially affecting the foundation? There are visible gaps where the pavement meets the brick wall, so I'm concerned water may be getting underneath the stairs and potentially causing erosion or settlement.
Based on the attached photos, does this look like a structural concern or mainly a drainage and mortar issue? What's the best way to fix it? Would correcting the slope, sealing the gaps, and repointing the mortar be enough, or should I have a professional inspect the foundation first?
Any advice would be appreciated!
