Basement drywall
Moisture-resistant drywall is a useful product that gets sold as something it is not, so it is worth being clear about what it actually does.
Moisture-resistant drywall is worth paying for in some parts of a Louisville basement and is close to wasted in others. Since it gets quoted as a blanket upgrade more often than not, here is where the line actually falls. This is for homeowners looking at a board spec they did not choose.
Treated core, and a facing that does not feed mold the way standard paper does. Newer versions use a fibreglass facing instead of paper and perform better again.
The thing it protects against in a basement is ambient humidity. Warm wet summer air meeting cool below-grade surfaces is constant in Louisville, and standard paper-faced board in that environment will eventually grow something along the bottom edge.
Bathrooms and laundry areas, always. The wall behind a wet bar sink. Sometimes the full exterior perimeter where the basement runs humid in summer or the block has shown efflorescence before.
We do not sheet an entire dry basement in it. It costs more per sheet, and in a space with good drainage and a dehumidifier running, standard board on the interior partitions is fine. Spending that difference on better taping under drywall hanging and finishing gets you a visibly better room.
If water is getting in, this is the wrong conversation entirely. Board grade buys tolerance against vapour, not against liquid. We will say so rather than sell you upgraded sheets that fail anyway, because finishing over an active moisture problem turns a nice room into a mold problem.
Behind a shower is a different question again. That gets cement board or a waterproofing membrane, because moisture-resistant drywall is not a tile backer. It is part of basement shower installation.
We look at the space in summer conditions where we can, check the block for efflorescence, and ask what each room is going to be used for. Then the board spec follows, wall by wall, as part of basement drywall in Louisville. Flooring choice follows the same logic under basement flooring in Louisville.
The right board where it matters, standard board where it does not, and the difference spent on something you can see.

Worth knowing
Moisture-resistant board resists humidity and resists mold growth on its facing. It does not survive standing water. If a wall gets wet, the board grade makes no difference at all.
We stay inside about 20 miles of Louisville so the crew is on site when they say they will be. These are the areas we cover most often.
