The price of drywall ranges from $12 – $20. Moisture-resistant drywall costs $14 – $18 per panel. You will pay $0.40 – $0.50 per foot to install it. It is more expensive than standard drywall. While it is moisture-resistant, it is not fully waterproof.

Here are some of the notable features of the green board.

Moisture resistant

The most prominent feature of green board drywall is its moisture resistance. It means that this type of drywall handles moisture better than standard drywall. Hence, it is installed in areas with high moisture levels.

It cannot be installed outdoors or in showers since it is not waterproof.

Thicker than standard drywall

Green board is thicker than regular drywall. The extra thickness provides its moisture resistance capabilities.

The thickness on the green board comes from wax infused in the material used to make the drywall panel.

However, exposure to water makes it weak and it tears down easily. Therefore, it should be installed in areas of moisture and not water.

Not fire resistant

Moisture-resistant drywall is not fire resistant. If the building code in your area requires you to install fire-resistant drywall, the green board will be useless. It may be the same thickness as fireproof drywall, but it is not fire resistant.

Fireproof drywall slows down the spread of fire. However, wax that is used in moisture-resistant drywall will melt when exposed to fire or heat. Consequently, the fire will spread fast if you use moisture-resistant drywall.

Durability

Green board lasts longer than standard drywall. Moisture-resistant drywall is made with more gypsum than standard drywall.

In addition, the layer of paper ensures that the drywall has superior moisture handling capabilities and protects it from environmental factors that may reduce its lifespan.

Uses of moisture-resistant drywall

As its name suggests, moisture-resistant drywall handles moistness better than standard drywall.

As a result, it can be installed in areas of the house that have more than ordinary moisture levels.

Green board can be installed in the following areas:

  • Bathrooms
  • Sink
  • Laundry rooms
  • Basements
  • If you are building your home in a humid region
  • Utility rooms
  • Crawl spaces

Moisture-resistant drywall, however, is not waterproof. Consequently, it should not be installed in areas that have water such as

  • Saunas
  • Steam rooms and
  • Indoor pools.

Benefits of moisture-resistant drywall

  • Easy to use and install.
  • Eco-friendly.
  • Good for insulation
  • Numerous design options.
  • Balance humidity in rooms.
  • Good for sound insulation
  • Lightweight enough to install in ceilings, walls, and other areas.

Factors that determine the cost of drywall installation

Type of drywall you use

There are many types of drywall you can install in your home. Each type of drywall has its purpose and price.

Standard drywall is the most common gypsum board used to finish homes. Depending on the building code, you may require waterproof, fireproof, and soundproof gypsum. Standard gypsum does not possess these capabilities.

Therefore, you will pay more to get these specialized drywall types.

The size of your home

The larger the house, the more drywall you need. Consequently, the more you will pay.

The larger your home, the longer the drywall installation job will take. Therefore, you will pay more for labor.

Drywall finishes

There are up to six levels of drywall finish. They range from

  • Level 0 – where you only hang the gypsum to cover the walls. It is mostly a basic, near-shoddy job as it leaves the joints and fasteners exposed.
  • Level 1 – It improves slightly on level 0 by covering up the joints and fasteners.
  • Level 2 – Improves on level 1 by covering the whole wall with compound in preparation for tiling.
  • Level 3 – Smooth walls due to a second layer of compound.
  • Level 4 – An additional layer of compound that gets the wall ready for painting.
  • Level 5 – Proper finish which may include painting and other decorations.

DIY or hire a professional

Drywall installation is an easy task that you can easily DIY. It is often a two-person job. Thus you will need help. If you DIY successfully, it will save you lots of money that you would pay to hire professional installers.

DIY installation costs almost three times less than if you hire a pro.

Pros charge per hour or by the size of the house. The longer it takes to install your drywall the more you will pay. Similarly, the larger your home, the more you will pay.

Drywall thickness

Drywall is available in ¼, ½, ⅜, and ⅝ inch panels. The thicker the drywall you choose, the more you will pay. If you are on a budget, you can purchase the ¼ inch panels that are more affordable.

If you want to soundproof, the thicker the drywall you choose, the better the results. ⅝ inch thick drywall panels are used to soundproof and fireproof homes or rooms.

Shape and height of your home

If you are installing drywall on high ceilings, you can expect to pay more. Additionally, if your house has odd shapes, you will pay.

The higher the ceiling the more work needs to be done to install drywall. The task may require more than two people to complete successfully.

If your house has an odd shape, you will purchase more drywall panels as they have to be cut to fit. Hence, the installation will cost more than in an ordinary shaped house.

Shape and height of your home

Removal

If your drywall installation involves the removal of existing drywall, expect to pay more.

If you hire pros, they will charge you to remove the existing drywall. To lower or eliminate the removal cost, bring down the existing drywall before the pros arrive.

Additionally, the removal of existing drywall increases the project period. Thus, you will pay more.

Types of drywall

  • Green board. It is moisture-resistant drywall. It gets its name from the green paper that covers the gypsum and fiberglass that make up the board. The green paper and additional wax on the board make it moisture-resistant.
  • Purple board. Covered with a purple paper layer, it is waterproof, mold, and mildew resistant. It is also the most expensive type of drywall.
  • Plasterboard is a drywall type manufactured with plaster veneer. It is also known as the blue board.
  • Fire Resistant. Also known as Type X drywall. It is recommended in building codes for its capability to slow the spread of fire. There are different categories of fire-resistant drywall depending on how long it can stop the spread of fire.
  • Soundproof drywall. It is installed to keep noise from coming in or going out of noise-sensitive rooms.
