How to properly insulated shiplap sheathing on brick veneer

Recently bought a fixer upper 1929 two-story house in Texas. What would be the correct way in insulating the exterior walls if the walls have a layer of brick veneer followed by an air gap, followed by both interior and exterior shiplap sheathing, then finally drywall. Do I need to gut the wall, taking down the interior shiplap, exposing the studs and exterior shiplap sheathing? Any suggestions on how to approach this.

Hi Anthony,
Seems like it would be okay to retrofit dense-pack cellulose in your walls, assuming that they are not leaking. If rain water is getting into the walls, that needs to be fixed first.
Dense-pack cellulose is an environmentally-friendly option that provides decent R-value and some air sealing and would avoid the collateral damage of completely gutting your walls.
If you did choose to gut the walls, you'd have the opportunity to do better air sealing, you'd have more options for insulation, but that's a much bigger project.

Thanks for the suggestion. My only concern with this method would be moisture. I don't no if I have any gaps on the other side, or if moisture would collect when I dont have a vapor barrier in place. As much as it pains me, I may have to gut the walls just to have the peace of mind.
