Atlanta Home: Master Bathroom Drain Leaks in to Garage

[Amit Bhavsar]

Hello Experts: we just had home inspection done for a home in metro Atlanta, and the inspector told us that the Master Bathroom Drain leaked in to the garage. See Pictures below. Not sure if this is a large fix or a small fix. I will be talking to contractors however, not sure how I evaluate each one as everyone can give their version of the story and justify charges and how much to estimate

Any tips/guidance will be appreciated on the right way to proceed. Also recommendations of plumbers you have worked with appreciated. Thanks in advance.
