Help! Balcony leak caused a drip in house (minor mold formed)

We had a bad storm & flood here a few weeks ago. As a result of several inches of water collecting on a limestone balcony at my parents' house, their dining room started dripping a couple of hours later. It only lasted a few hours and was the only time it ever happened (was also the worst storm that's ever hit their area, normal downpours weren't even close to being that bad). A small amount of mold started to form on the drywall ceiling (about 1 ft by 1 ft in 2 different areas & was light green), so we cut it out and wiped what else we could see with a bleach/water solvent.

The bleach/water solvent worked like a gem, but I'm worried about a couple of other things... a) the areas we can't see & reach, such as between studs & plywood or something like that. b) any contamination the small amount of mold caused in the house, such as by releasing spores on the walls, carpet etc...

Does anybody have any experience or advice on how to proceed? I've been warned about "model cleanup specialists" because they can get pricy and I wouldn't be sure if they're needed and do a great job. I don't know much about mold other than the negative things I've read about it over the years (especially extreme cases like what Katrina caused, but this is obviously a much more minor instance than something like that).

To fix the balcony, we're either putting copper flashing to prevent it from leaking again, or sealing/tarring & drilling holes in the front to drain any buildup of water. If anybody has a recommendation on either of solutions, I'd love to hear opinions. The copper flashing route will probably be much more expensive bcz it requires removing the limestone first & cutting into the brick, but if it is a permanent solution that works, we don't mind spending the extra $. We just want to make sure it's properly done & the way to go.

I appreciate any input, advice, etc...

 

Thx for the reply Bill. We've had a few people out to check it out this week and it looks like the problem wasn't too bad. The leak is being fixed, the drywall that was damaged is being replaced, and the mold is being remediated. An air sample test of the room showed that the mold wasn't toxic, so that was good news.
