Front wall of house has a brick exterior. The interior is plaster. There had been some water damage to the wall that turned a swath of plaster below the window into -- essentially -- dust. Gonna just square off the existing, solid plaster and put drywall in the gap. My questions:
1. can/should I install backerboard underneath the drywall? it would serve two purposes -- a shim to bring the dryall relatively flush with the existing wall...and it would help with any unexpected water intrusion.
2. how do I fasten the drywall to the brick right behind it? Are masonry screws sufficient? other options?
3. probably a stupid question...but do I need to remove the baseboard and the trim under the window sill in order to install? If I were able to slide it in behind the trim and under the sill and then bring it down into the existing gap behind the baseboard (the plaster is GONE from here), can I just fasten it directly through the trim/baseboard? I'm happy to clarify if this doesn't make sense.
Thanks.

Unless your house is structural brick, you should square off the area to the next adjacent studs and then fasten the concrete board and drywall to the studs.
If it is indeed structural brick. you will need to pre drill into the brick and use masonry fasteners like Tapcon screws to hold the drywall or concrete board in place.
A better method may be to simply use concrete board then skim coat the surface with plaster to match the old.
There should be no problem digging out the old plaster from behind the base molding then dropping the new concrete board/drywall into the space behind it.
