Drywall is a part of most residential homes and a material to consider when building. Most commonly used in homes is Gypsum-board drywall. Gypsum-board is not water-resistant and is prone to moisture damage and mold growth. Choosing a water-resistant drywall for areas in your home that are prone to moisture is a good choice.
Moisture-prone rooms you may want to consider include the kitchen, bathrooms and basements. Being exposed to moisture, these room are more likely to see water damage or mold growth. Regular drywall does not protect your home from water and mold damage and may need to be replaced in these moisture-prone rooms. Installing moisture-resistant drywall from the very start is the best and most cost efficient choice.
On average, standard drywall cost $0.34 to $0.41 per square foot while upgrading to moisture-resistant will cost $0.40-$0.48 per square foot. Though every room in your home does not need moisture-resistant drywall, installing it in the moisture-prone rooms is an inexpensive upgrade that could save you from costly repairs down the road.
