Vapor Barrier On Brick?

Doing a reno where the propane insert turned into a rip out and reframe...
Found (very light) mold on drywall surrounding the old wood fireplace, which is surrounded by brick. Not sure how to approach this mold situation, any idea?
There was no insulation around the old insert, and it is very drafty. But I dont want to fill the cavities and find it full of mold in a few years.

Any help appreciated.

Cold climate btw

Re: Vapor Barrier On Brick?

wood fireplace = HOUSE FIRE.

Supply OUTSIDE combustion AIR for ALL oxygen using heating devices.

Keep outside damp & cold air out of chimneys with top mounted spring loaded dampeners that are SHUT when not in use. and still close legacy smoke damper to reduce air changes in chimney.

Don't operate fireplace in a condensing mode( too low of heat to insure stack gases are still in a vapour phase(no liquids))

Avoid paper Gyp boards....

Vapour barriers installed in fireplace footings/ ash dumps, rain screen chimney construction....Flashed multi- wythe damproofed construction with air cavity rain screen/vent space.
