Water leaked under laminate floor boards. What's the plan?

[Silver Gaia]

1. We had a similar thing happen in our family room,

which was added by a previous owner atop what had been a concrete patio. As I recall, we used an oscillating saw wih a flat blade to saw along the joining lines of the laminate we needed to replace so that it could be lifted out. Our piece had to be replaced because it had warped, but we just removed the appropriate parts of the new piece and used flooring glue so that it could be laid in flat to replace the damaged portion. You can't tell unless you know what you're looking for, so WE know, but no one else notices. I hope that helps you!
