Some past "plumber" decided it was OK to cut a notch for a 1-1/2" PVC pipe directly through all the 2x4 studs on one end of a window header. The result, shown in the photos, is a buckling wall.
The studs are actually pinching the PVC pipe now, which maybe helped to arrest the problem.
Of the four studs affected by this, one is a cripple under the window, and the other three are king/jack studs. The window opening is only ~38" but this is on the ground floor of a 2 story house.
(This is US-style construction, in case that wasn't clear).
Methods I'm considering to remedy:
Replace at least the 3 king/jack studs. Obviously correct but will require some temporary shoring.
Leave the existing studs, but sister some new wood with some stout lags or bolts. Would have to contend with having to straighten the wall first.
Pull the wall back to straight (clamps, big post, etc.) and fill the notch with new wood.
As it happens I have access to both sides of this wall due to the work going on. So I can work easily from the inside or outside.
Looking for feedback on any/all of these ideas or alternatives!
I'm experienced enough to execute any of these ideas, and have the tools do to so. But this is bad enough that I'd value other's opinions on the approach. Ultimately I want to choose a solid long-term repair whilst avoiding excess cost/labor/etc. But I've no need to "cut corners" or do only a "band aid" fix.
Thanks so much.
Just as a commentary: among the stupid things I've discovered over the years of rebuilding my house, this is the most thoughtless.
