My gutters get overwhelmed in very heavy rains and then dump water off
the ends into a depressed area that fills the window well from the
sides, not the top so covers don't help although they are in place.
There is a large tree with ground roots that I will remove and order a
load of dirt to re-grade the area away from the house foundation and
window well. I also have a covered patio that has had the dirt
underneath it eroded over time (also a family of foxes dug a den there
several times) so I need to fill in under there since it is another
low point next to the house. Or I might call in a mud jacker to fill
New larger gutters and drains would also help.
However, I am probably to paranoid to leave it at that and will
install a larger sump pump.
The last two heavy rains I ended up outside bailing water out of the
window well to keep from going in the basement. It's not a lot of fun
when you are soaking wet, cold, muddy, and tired of bailing water.
