Structural. Hoping I can get some help for my house. I plan
Hoping I can get some help for my house.

I was wondering if the following solution would work, taking into account the whole floor will receive hardwood Ripping 11 7/8s lvl in half and sistering the sagged joists after jacking them level. - that would mean a 5 15/16 lvl screwed onto one side of the 2x8 joists. - what would be my screw pattern here? - would I be using sds screws? - would I have to glue the lvl to the 2x8 joists? - would I have to do the whole floor or just the LHS that is sagging that much. Thank you in advance … read more
