Boiler *might* have caused water intrusion... who do I call?

Question

apologies if this is a super basic question, but this is my first time owning a home and not sure who to call.

So my boiler seems to be leaking -- I think this may have been happening for a while, but the problem is that my bedroom is right next to the boiler. I'm worried, based on the white circular pattern (mold? sediment?) where water has been presumably pooling (1), if water might have intruded into the adjacent wall space and under my carpet through the slab, and who knows where else, and caused mold growth.

What is the process for stuff like this? Should I just call a general contractor to fix the boiler and possible water damage for the wood underneath? But I don't know if they would be very thorough about any mold growth... should I call a mold inspector before, afterwards, or even during? (Maybe I am being a bit crazy about the mold, I am kind of sensitive to air quality though as I have sinus issues...)

You call a plumber and get the water heater replaced. Most of the white junk appears to be mineral build-up from ignoring a leak for a long time.

Have the new one installed properly to code with a drain pan. Not like this one was, with no drain pan evident.

If you want to rip the house apart on the possible suspicion that there could be mold, you'll need someone other than a plumber, too. Presumably a mold remediation specialist if you're particularly paranoid about it. I'd suggest fixing the leak and keeping an eye out for actual signs of a further problem before ripping the house apart, but it's your house.
