TE certified will have to cut approximately 20 sq/ft of sheet rock, reroute the stack as it drops down the wall, drill a new hole through the flooring, reroute the drain line and tie it into the main trunk line. Sheet rock will not be replaced or repaired by TE certified. also, in addition to the last estimate provided, we would need to reroute two 1 1/2 PVC drain lines and tied into a 3 inch ABS line raising that 3 inch ABS line and notching it through studs, ensuring proper slope on all drainage connections. Approximately 4x drain lines would need to be reworked. also, we would need to be abandoning two gas lines and rerouting the way that they run. No permits would be required
