Our house was built in 2018 and I understand that some drywall cracks due to settling are normal, but I'm wondering if this cracking is due to the stairwell not being properly supported.
The first three photos are of the stairwell to the second floor. The cracks are in line with the second story floor. The last two photos are of the stairwell leading to the basement. The two stairwells are vertically in the same space. album
We were planning on patching up the drywall ourselves, but I'm hesitant to now if this is a bigger problem. If it's an issue with support any ideas on how it gets fixed or what kind of professional to hire?
