Our one-story wood framed house was built in 1913, and has 2X4 wall studs, ceiling joists, and rafters. There is a window in the front exterior wall about a foot away from the front door on the "strike" side of the door jamb.

When the front door is slammed, the front wall that includes the window shakes. I've tried running long screws through the door jamb on the "strike" side into the adjoining stud, but that didn't improve things.

Now I'm wondering if I could stop the shaking by going into the attic on that end of the house and bracing the plate above the jamb with short lengths of 2X4 run from the plate to the first joist. The ceiling below the joists is gypsum board over the lath that used to hold plaster.

Any suggestions would be welcome!
