How to properly support the header when expanding a door opening

framingplastersupport

I'm opening up a closet in our 1958 home.

I believe (I plan to get confirmation from a licensed contractor or engineer) that this is not a load bearing wall considering that the opening runs parallel to the joists in the attic above, the wall is an interior wall for a bedroom behind, and considering the way this was installed (both sides of header not resting on a support).

I'd like to remove the left side of the closet opening to get as close to the exterior wall (masonry) as possible. I plan to keep the 2×4 headers in place just because it will be a whole lot less work for me. I am wondering if I should install a framing bracket of some sort to provide support to the 2×4 headers that will no longer have the 2×4 vertical support.

From what I can see here, and assuming not a load-bearing situation, I'd do this:

  • Remove the existing header. You may need to use a recipro saw to cut fasteners behind the plaster on the room side.
  • Since you have access from the back side, run a new, full-width double 2x6 header. If you don't have trimmer studs or other support available, fasten the header into the king studs with lag bolts. I'd probably use 3/8" x 4", properly pre-drilled and countersunk.
  • Toenail into the pin studs to anchor them to the header.

Optionally use construction adhesive where needed for additional support.
