I think we have a winner.


I'd get outside and make sure the yard is correctly pitched away from
the house on all side. Why is that gutter overflowing? Where the
downspouts end, the bare minimum is to have a long splash block to get
the water away. Much better is a length of flexible pipe that can
take it 6ft or so away, but that can't always be done.

And get outside in a heavy rain and see what is really going on. You
may find water screwing things up that you never expected. I was
having a problem and went outside to find that the flex pipe on the
downspout was not shoved on high enough. When there was a heavy
rain, the pipe was overflowing right at the foundation. If I didn't
look during a heavy rain, I'd never have realized it.
