Should I replace my blue board after it got wet from a water heater leak?

My hot water heater leaked a week ago and created about an inch of water in my storage area of my basement. The storage area is unfinished and is blue boarded and the walls are insulated, and on the other side of the wall is a finished bath and carpeted playroom. The playroom carpet pad got wet and the baseboard moulding in the playroom and bath pulled away from the wall a bit. I cut holes between each stud in the storage area and pulled back the insulation today (nine days after the leak), and the backside of the blue board to the bath and playroom is damp. I am airing it out now. My question is should I replace the blue board to the playroom and bath, or would I be ok by drying out the blue board, wash with borax and/or bleach, and not replace the blue board to the finished rooms?

microban is your friend. if it's not warped you can prevent mold from ever growing by getting a gallon of microban and a pump up sprayer. spray the effected areas and air dry. fans down there also would help, air should be circulating

By airing it out I hope you mean you are running fans on the watered boards.

Fiberglass insulation will not dry out even with fans blowing on it. It must be removed. Just 1% moisture will ruin the claimed insulating R-value.

I saw mold on homes after the Katrina repairs were made and were sprayed and treated and the owners needed money to tear out the repairs and open up everything. Just removing the bottom 4' of drywall was not sufficient as rveryone learned quickly.

A week ago..... the mold is there now, the board is now cottage cheese, the framing wood is wet.... If caught and forced air dried soon- ok.

Be safe, Gary
