Front door gap

Afternoon everyone. I am trying to find the best lace to post this question so please move if needed. The front door to my house currently has this lovely gap around the lock. Putting weather stripping in the area doesn't fill the gap. Unknown how best to fix this, any suggestions would be appreciated.

 

Has that gap always been there? is there any evidence of the wall having moved any?

 

Does the gap go away if you push the door closed tighter?

 

Gaps been there since we've moved in. Don't see the gap disappearing when the door is pushed together. I do notice that the alarm sensor is even with door, so it makes me believe the gap has been there for awhile.

 

So what is your complaint... the gap to the left of the door? Is it drafty? If the gap is largest at the lock, my guess would be that someone screwed the screws in too tight with no shim behind the jamb.

Normally when a door is installed, you use a 78" level, hold it against the hinges, plumb and shim the door, then you do the same thing on the latch side. So if your jamb isn't straight, but I'd bowed at the latch, the solution might involve removing your strike plate screws, removing the trim on that side, then insert shims between the jamb and the 2x4 framing to make the jamb straight again.

But if the gap is large at the top left corner and all the way down, that won't help. You would likely also need to shim the hinge side if the door jambs are spread open. You could check by measuring the width of the opening with a tape measure at various points... the sides should be parallel.

And it's possible that the door is not original to the jamb... they sometimes don't fit as well as the original door.

 

Thanks for the help everyone. If the door isn't original, will need to look into some solution. Renting the house and I doubt the owner is going to fix this. At least I know what to look into going forward.
