Looking to square up an existing front door
This past week, I noticed a 1/4" gap along the top left side of my front door (viewed from inside). After further investigation, I noticed the frame is out of square. Now, I'm not sure what happened here since my framers installed the door, and it was square during installation. I'm assuming settlement/drying lumber must be the problem here.
But my question to you is how to I square it up?? The actual door is level, but the frame isnt...
To make this even more complicated, the door is trimmed out and it has two sidelights on it...fully finished & stained...
The gap isnt really noticeable until you come down the stairs when you see actual daylight..
Any suggestions on how I can fix this? I'm attaching a photo to give you some reference. The circle shows the area where I'm able to see daylight.
Any help would be greatly appreciated.
