We had the water line for the water softener come loose in the middle of the night and flood the garage. When we woke up and discovered it, we immediately tore all the wet sheet rock, etc out, dried everything with fans and treated for mold. Now for the repair, we are totally stumped. It's an older house - about 38 yrs old. There is the outside wall which is limestone, then there was this thin, cardboard like moisture barrier, then the framing 2x4's. After pulling out the wet moisture barrier which was like paper when wet, there was just the stone wall. Because the 2x4's are anchored to the stone wall you can't easily just slip new moisture barrier behind them for a quick fix. We've gotten a variety of opinions from six different carpenters,contractors and a mason guy, which include taking down the outside stone wall to install new moisture barrier, installing new barrier between studs, and removing stud frame inside to attach moisture barrier to and then anchor back in place. There are minor cracks in stone wall (from stones not being placed correctly we're told), however one carpenter who also has a number of yrs of masonry experience told us the wall was very stable. He's the one that recommended pulling studs down, putting moisture barrier on studs/frame and re-anchoring to stone wall. We can't get a hold of him though to get work done. Makes me think he's maybe nervous or unsure about job? What would you say is the most economical, and adequate fix? Please Help!
