Doors sticking?

Door sticking is one of the first signs to look for if you are suspecting foundation issues.

Now looking at the reveal at the top of the door, the reveal should be straight. If the reveal is bigger on one side compared to the other, it is time to investigate further. Are there cracks in the drywall? Is there any odd lumps or bumps in the drywall, if the answer is yes then it is time to call Superior Foundation Repair.
