I need to replace the header above a 1sr floor window. It is 2 2x10# at 48 inches across with a piece of osb sandwiched on top of a 2*4. I am curious if I need to build a support "jig" while I am working on the problem area. Windows and siding were recently replaced everything is bone dry now so just was trying to figure out how far the cancer spread and got a little deeper than expected. Thanks in advance for any help or advice.

Are yiu replacing the header or a joist resting on the header– KrisCommented Jan 22, 2021 at 0:29

Both. They both are pretty far gone. The 2x4 as well as the 2*10s. Thanks!– Cliff SuttonCommented Jan 22, 2021 at 1:04

Are the ceiling joists parallel or perpendicular to the header?– KrisCommented Jan 22, 2021 at 1:09

Do you need too?
Probably, but that may depend on exactly how much is above the header/load bearing wall you're taking out.
Should you?
Yes. Build a temporary wall to support the joists, ceiling, upper floors, whatever is above this. The cost in time and supplies is minuscule in comparison to any damage that may happen to the structure while you've got that load unsupported. Additionally, your insurance company could use the lack of temporary bracing as an excuse to not pay a claim, making it even more expensive.
While you're at it, ensure that your load is carried all the way down to the ground. You don't indicate if you've got a slab, basement, or crawl space, but if you're not on a slab, you'll want to build a temporary wall in the basement/crawl space directly below the one you're building above. This will support the joists right where the load is instead of bowing them down with the weight from above. Again, consider the actual costs vs the potential costs to repair damage.
