Among other things, an energy audit that I had done showed two "holes" in the insulation -- which I believe was caused by a failure of our contractor to install fiberglass insulation in these areas. I am considering two options:
1) Cut out the sections of drywall and install the fiberglass insulation as it probably should have been done in the first place, or
2) Drill a few small holes in the drywall and spray in insulative foam.
I am sure both options would be pretty easy for a seasoned pro, but I am no seasoned pro and the thought of putting holes in otherwise perfectly good looking drywall scares me. Which method would likely be the least intrusive? Most effective? Are there other options to consider?
I guess I should point out that the drywall in question is high on the wall near the ceiling and that the only way to access the area is through the finished side.
