Have a 35 year old house; split level style.
Never had any drywall cracks, etc.
I have just noticed a (new) drywall crack running vertically along a wall
Beginning at the ceiling, ends at a window, and picks up again underneath
the window down to the floor.
This is all on the second level of the house.
Nothing has propagated to the first level.
I guess the simple thing is just to say the house has "settled," a bit, but
after 35 years ?
What causes these sort of cracks ?
Any thought on would be appreciated.
