How to conduct Mold remediation in tenant spaces

[Sb Carson]

Triplex damaged by mold due to leaking roof of neighboring building.  Water leaked down party wall causiing mold in our building.  Mold is apparent in first floor unit.  First floor walls that had visible mold have been torn out to dry and dehumidifiers are running.  

The neighbor roof leak has been repaired by neighbor.  Now we must get our units repaired and we want to be sure there is no lingering mold.  The building still smells like mold.  We are assuming that remediation is required. Anyone have suggestions for procedure and Philadelphia local company that would deal with mold issues?
