Window Wells & Grading

I would like to enlarge a window and put in a window well. The ground slopes in the backyard and after a heavy rain, water pools in the middle of the yard a bit. Is there anything I need to worry about with regard to grading.

I know 2 people that have window wells and they both had flooding in their basement. Is there a relationship with window wells and flooding?

Sure looks like you could add fill and raise that grade at least 6" to get the water to run away from the house toward the yard.
If the well does not have the proper drainage in the bottom of the pit, grade does not run away from it, foundation wall was not waterproofed before back filling, waters going to get in.

Yep----the new window well will need a drain----

Does your house have perimeter drains and a sump pump?

If not, your new larger window will require some trenching and a sump pit-

That part might be more work than adding a window and a window well-

Grading, gravel, and a properly installed vertical drain leg into your weeping system is pivotal.

I would add a battery back up to the list as well if your sump runs during rain storms.

A good sump system a must but there is not replacement for proper grading and moisture direction.
