Standing water in yard and window well

[Robert S.]

My basement has flooded, possibly due to standing water in one of the window wells. There is water pooling up under the mulch next to the window well on the side of the house, and I can see water seeping into the window well. The house is a year old, and I am out of warranty. Is it normal to see standing water under the side of the yard under the mulch? Also, I cannot step into the backyard as it is very muddy. The builder has corrected grading issues twice before where there was standing water in my backyard, but it looks like the issue was never resolved. How did the water get into my basement? Could there be a crack somewhere? I am really hoping someone could help me with this, as I never slept after this happened and am worried. We put a lot of effort into finishing the basement. The carpets are damaged as well. I have a restoration company coming tomorrow, but for now, I have put a sump pump in to drain the water out. I have attached a video link for reference. Thank you, guys. Video https://drive.google.com/file/d/1-PVmNYqz2zUTy0wHpx65SG7aJ9U...
