Anyone ever use a whaler for temporarily supporting a span like this (9'). This is a garage under, 1-1/2 story. 2 of the 3 sandwiched 2x's have significant rot and ant damage. No sagging visible yet but replacing is required. Shame that $7 worth of flashing would have prevented it($650,000 house, 7yrs old).
Anyhow, I am trying to avoid touching the garage door and some ductwork on the garage ceiling if at all possible. Avoiding this would be difficult with a traditional temp wall.
I was thinking whaler would be lagged into 1st floor rim. Set on 4x4.
Let me know your thoughts good or bad.
