The boss, err wife, had a guy down the street put a doorway in and build a patio deck for my mother’s upstairs apartment.
He seriously undersized the main header beam (a single 2×10) and didn’t support it on the posts. After 6 years it had developed almost a 2 inch sag, very visible from the street.
I did some research and decided to put a doubled 2×12 beam in under the original.
I used a 100 year old screw jack with a strong back to raise the sagging beam up.
I notched the support posts to inset the first 2×12 under the joist support beam (which he cut to mount the handrail posts.)
Then I Twinned the second 2×12 under the outer beam.
I hooked everything together with a couple of Simpson strong tie support brackets and 5/8” galvanized bolts. Then I put a couple of 1/2 galvanized above that for additional support.
I finished up the twinning process adding in some vertical 2×8 ties with 1/2 galvanized bolts and a few dozen galvanized framing nails.
Appreciate any comments.
