Re: Renegotiating offer after home inspection
If the walls have no major visible signs of mold (in the garage) i'd leave them alone, perhaps use it as a point of negotiation, but wash them lightly with a water and bleach solution, let them dry out really well, put some fans on them, and then prime and paint with a semi-gloss, caulk the base and corners and leave it alone... if there's mold behind the walls, why disturb it? drywall is fine in the garage, its the carwashing thats the problem!! if you are looking for a more durable material that is mold resistant, use hardi-board...much much more durable than drywall...
no one has put their guess on the costs, i'd say about $5-600 for a sub panel upgrade, and about $3000+ to R&R the garage drywall... but once you strip the garage, depends what your local regs are for mold remediation, if you have to glove-bag moldy drywall add another $1500-2000 to that price...and since you have the drywall off, run some more wiring for power, add some lights, retape your vapor barrier...
