  1. Is this mold?

    HVAC
    I took the front panel off of my AC air handler looking for a common wire for a smart thermostat. When I took the panel off, I found a couple of wires have what I think is dried mold on it, but I'm not sure. Does anybody know what else it could be? These wires are above the coil. Whatever it is...

  12. After a flood, okay to remove less than bottom 2 feet of drywall?

    Drywall & Plaster
    Some emergency flood restoration workers say that it's necessary to remove drywall touched by water, starting at the floor, up to two feet (60cm). To me, that sounds suspiciously like a magic number, not necessarily supported by science. Would it work to simply remove the baseboard, and then...
