Is regrading going to help with my water issues?
Absolutely! I would start here first and then look at your downspouts in the area where the water is the problem. Don’t let anyone tell you, adding mulch or top soil is the trick Regrading with these two materials will not compact tight enough to run the proper amount of water away from the foundation. A good compactable soil is the answer, half clay soil and good old earth will do great job. If clay is not available then good old earth will be fine. Make sure they tamp it down tight.
