My family moved into a place 5 months ago and there was mold growing.  We tried to fix it but did not have any luck.  We called SERVPRO to come help us.  They were here the same day which was much appreciated.  Though they could not yet do anything as they mentioned the source has to be determined and stopped, they educated us on the process and even scanned everywhere with their fancy camera to see if they could find the leak. We will use them once the issue is stopped.
