I want to know when there is a need for mold removal once the contractor has removed the mold, is their a possibility of needs for other contractors to come in to do some repair work if you have mold on the drywall, floors, ceilings, and in the bathrooms (like in the shower and around the tub?

Any info will be appreciated.

Thanks in advance.

First tell us how the contractor removed the mold, what did he do and what did he use. Was it really just drywall in the shower or was it blue board or backer board?
