Second Story Deck repair

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.

It always amazes me, with the number of awesome span calculators out there on the web, that people get this wrong. On the other hand, that is the hard dimension to get right. Congrats on getting it fixed up!
