What is Greenboard Drywall?
This moisture-resistant drywall type is often the first choice of contractors and DIY homeowners when they remodel spaces that are likely to be exposed to humidity because greenboard stands up to water exposure better than standard drywall.
This water-resistant gypsum panel debuted in the 1960s to enthusiastic remodelers and it’s easy to recognize due to the green tint added to the paper that is treated to a wax sealant before it’s sold.
Thicker than standard drywall, greenboard is sold in panels that are either ½-inch or 5/8ths-inch thick.
Pros of Greenboard
- -It’s designed to be installed in areas like bathrooms, laundry rooms and areas subject to outdoor intrusions.
- -Greenboard does a great job of rebuffing organic growths like mold or mildew.
- -It’s available at a variety of retail stores and at varying prices, from hardware to big box stores.
- -It’s a breeze to cut using nothing more than a sharp utility knife and metal straightedge.
- -It’s installed just like drywall, but greenboard comes with more attachment options that run the gamut from screws to grout and other adhesives.
Cons of Greenboard
- -It’s more difficult to cover up seams when taping and mudding sections that have been installed.
- -Greenboard is not waterproof; it just resists moisture better than standard drywall.
- -Greenboard is not fire resistant, so it shouldn’t be used at high-risk locations.
- -Since it’s heavier than regular drywall, ceiling installation calls for special methods or sagging could result.
- -If it becomes completely saturated, greenboard can weaken faster than traditional drywall.

But the Home Advisor website is in the business of calculating averages based on extensive research, so for 2021, you can use these numbers when figuring out how much you are likely to spend on your unique job.

-If your goal is to apply drywall to the walls and ceiling of a 200-square-foot room based on these prices, expect to allocate between $300 and $500 for this part of your rehab project at between $0.40 to $0.65 per square foot.
-Thicker forms of drywall designed to add soundproofing and fire-retardant properties to the sheets are heavier and could cost you as much as $60 per panel, depending upon the benefits accorded to that type of drywall.
Cost of Cement Backer Board
Because cement backer board was originally made to be used on home exteriors (like siding), your search for pricing could be confusing, but if you prefer it over drywall, heating and cooling bill reductions could even out the cost so it’s worth investing in it if you have the choice.
According to Homewyse, you can anticipate spending the following if you purchase cement backer board:
