The complaint is that there is a water leak in the powder bath ceiling We found water stains and mold on the powder bath ceiling and wall There is no bathroom above the area so we cut open the powder bath ceiling and found no plumbing in the area of the water stains We did find the clear condensation line for the hvac unit is in the area and it is chewed up where mice or rats have been trying to get in to the water in the line we counted at least 6 holes in a 2 foot section This is not a plumbing issue it is a hvac issue Need to send out an hvac company Job completed No estimates needed This is a vacant house no one to sign
