I had several water leaks when my house was new. For smaller leaks that are caught quickly, the remediation guys just used the dehumidifiers and fans for a few days. They used moisture test gizmos to check the drywall down at floor level to make sure it had dried out. For a larger leak that went on a little longer, they cut out the bottom 12" of drywall to expose the framing, and also pulled up the flooring working from the wet area out until the flooring was coming up mold-free. A few cabinets had to get pulled out as well. These leaks were on interior walls so no insulation to worry about. After a week of fans and dehumidifiers my builder put everything back together - new drywall, flooring, and paint. In your case where the unfinished wood was totally submerged, I think I'd want to rip and replace it all since it will likely dry unevenly and warp, plus it will take quite a long time for the bottom of the wood to dry which will allow mold to grow. I personally wouldn't be too concerned about mold on the framing just yet for a short-term dousing like yours. Once the framing is dry any mold will die, and your builder can hit it with some bleach if it really bothers you.

You can rent a blower fan, or you can even call one of the remediation/clean up companies and ask them to put a dehumidifier in the house for a few days. Of course, the co. is going to try to sell you on a full clean up, so you'll have to stand firm on just having them dry up.

A good example of why you don't buy a house with zero setback on one side. Some basic info adding on to what Suzi said above. Stucco walls are only resistant to water. If there is no eaves protecting them from rainfall or if there are winds causing rain to hit them, they can get fairly wet inside. They have a space behind the stucco and any water that penetrates flows down the inside and out the weep screed. Soil needs to be 4" below that and the ground needs to slope away from the house at 5% minimum. 2% is allowed for a hard surface. If the project had a geotechnical report, it could make additional requirements. I guess that is a long preamble for my next statement, which is that the weep screed is there to get water out of the wall from rain and maybe some spray from watering - not drip watering. His ground level better NOT be higher than your cement slab. Clearly, there can NEVER be standing water above your slab level. He is totally wrong about his liability based upon what we see in your information, limited as it may be. Even without the zero lot line variable, it is routine large damage payments for excess watering, sprinkler leaks, or changes in grade drainage issues causing problems for downhill lots. Also, do your eaves hang over into his property? Are you in a HOA? Edited to add: I noticed this in a forum dedicated to old houses. Stucco houses built before about 1980 or so probably don't have a weep screed at all. Is this an "old" house, whatever that means.

No there is not a full width track as this is a frameless door. They typically just use the small pieces of track as a guide to minimize the amount of metal. Look for a CRL water deflector/wiper seal for shower doors, These get applied with either clear silicone caulk or VHB tape.
