I'm not sure how I ignored your first sentence. I also asked a question about it, which *you* ignored:
"Did you mean at basement footing or front porch footing?"
If it seems like I ignored it, maybe it's just a misunderstanding on my side.
Thanks anyway!
Regrading the outside will probably be the most help, as pointed out by the post above. It will make sure this is done once I have patched the various holes in basement walls and possibly front porch wall.
Waterproofing the exterior walls would only stop the water from penetrating the wall but wouldn't stop the water from pooling against the wall, so I don't see that as a solution; at least not a complete solution.
Footing perimeter drain would probably help evacuate the water away. Did you mean...
The front downspout is draining on the left side of the house (opposite corner seen in the picture), I would be surprised if this had any influence. The back of the house one empties back right corner of the house, and water runoffs towards the back of the garden. Which made me rule downspouts...
I recently discovered water is seeping through basement walls from under the front porch. Posting this to get fact-checked and read your suggestions on how to address the issue.
Given how close to water main the seeping was, I suspected the underground water was seeping through the foundation...
