There is a weird crack in my wall above the window. The way I would describe it is as if there was a finger pushing it out. What is it?

Question

Is this a job for a professional?

Update:

I just want to know what would cause this crack to happen in the first place. It is not a flat crack as you can see. 

Answer 1

Looks like an expansion crack. Something has expanded and pushed the surface outwards. Get some filler, dig out the area then fill it and smooth it out level.

Answer 2

Sometimes when a home begins to settle cracks develop.  Having a professional check it out if you want to pay this expense?  

Answer 3

Nail working it's way out. Pick off the loose stuff, set the nail. Fill with plastic wood, sand and repaint.

Answer 4

'get a professional' is bad joke -- your ordinary handyman can do this job just fine

Answer 5

Well picking out the loose stuff, patching, sanding, and painting isnt rocket science.
