Drywall solutions: Drywall is one of the most commonly used materials for building interior walls and ceilings in homes, offices, and commercial buildings. It’s affordable, easy to install, and gives a clean, smooth finish. However, traditional drywall does not hold up well during storms, especially when there’s heavy rain, flooding, or high humidity. Once water seeps into drywall, it can cause swelling, mold growth, bad odors, and even structural damage. In the worst cases, entire walls must be torn down and rebuilt.

As severe weather events become more frequent due to climate change, it’s important to start thinking ahead. This means choosing better, more storm-resistant materials and smarter designs. Let’s look at some of the most effective drywall solutions that can protect buildings during future storms.

1. Moisture-Resistant Drywall (“Green Board” or “Blue Board”)

Moisture-resistant drywall is a step up from regular drywall. It is coated with a moisture-blocking material, which helps it stand up better to humidity and minor water exposure. It’s often used in bathrooms, kitchens, basements, or laundry rooms—places where moisture is expected but not extreme.

However, it’s important to understand that this type of drywall is not waterproof. If your home floods or is hit by a heavy storm, moisture-resistant drywall can still be damaged. But in areas that are only slightly damp or humid, it works much better than traditional drywall.

2. Waterproof Drywall with Fiberglass Facing

Instead of the usual paper coating, this drywall has a fiberglass surface. Paper on traditional drywall tends to absorb water quickly and can become a breeding ground for mold. Fiberglass-faced drywall, on the other hand, does not absorb water as easily and offers better protection against mold and mildew. It’s a good choice for homes in coastal areas, storm-prone regions, or places that often deal with wet weather.

Popular products in this category include DensArmor Plus and Securock. These boards also perform well during cleanup after a storm, since they are less likely to crumble or fall apart when exposed to water.

3. Cement Board (or Concrete Backer Board)

Cement board is one of the strongest and most water-resistant materials available for wall construction. It’s made of cement and reinforcing fibers, making it highly durable. Unlike drywall, it doesn’t absorb moisture and will not support mold growth.

Cement board is typically used behind tiles in bathrooms and kitchens, but more builders are now using it in entire rooms or lower levels of buildings in flood-prone areas. It is heavy and costs more than drywall, but it can last much longer and offers excellent protection during storms and floods.

4. Magnesium Oxide (MgO) Boards

Magnesium Oxide boards are a newer and more advanced building material that is gaining popularity around the world. They are made from natural minerals and are resistant to water, fire, mold, insects, and even extreme temperatures. These boards are very strong and do not break down or weaken when exposed to moisture.

Even though they are more costly than regular drywall, MgO boards are worth the investment when living in neighborhoods that are at risk for ongoing storms or floodings. MgO boards promote long-term resiliency and eliminate the costs of repairs once a disaster happens.

5. Elevated Wall Design and Flood-Ready Construction

In areas where flooding is common, smart construction methods can reduce the damage when water does enter a building. One useful method is elevated wall design. Instead of running drywall all the way down to the floor, builders stop a few inches short and use waterproof or removable materials on the lower part of the wall.

This can include plastic panels, vinyl trim, or moisture-resistant wainscoting (decorative wood or paneling). If flooding happens, the bottom portion of the wall can be easily removed, cleaned, or replaced, without tearing out the entire wall. Electrical outlets can also be installed higher on the wall to keep them out of reach of floodwaters.

6. Removable Wainscoting Systems

Some homeowners and builders are now using removable wainscoting, which covers the bottom part of a wall and can be taken off quickly if a storm is coming or after a flood. These panels are usually made of PVC, composite wood, or other water-resistant materials. This design makes it easy to access and dry out wall interiors, which helps prevent mold and speeds up recovery.

7. Sealed Drywall and Protective Coatings

Another solution is to use sealed drywall systems, where the joints, seams, and screw holes are sealed with special waterproof compounds. Then, a waterproof primer and paint are applied over the entire wall. This creates a barrier that helps keep water out and reduces damage if there’s minor flooding or water leaks. This system doesn’t make drywall waterproof, but it adds an extra layer of defense.

Why These Solutions Matter?

Traditional drywall is not built to withstand today’s increasingly unpredictable weather. Floods, hurricanes, and severe storms are becoming more common, and with them comes the risk of major water damage inside homes and buildings. Migrating to the use of denser drywalls and intelligent building design assists:

• Lessen repair expenses following storms
• Preserve from mold and health hazards
• Extend the lifetime of a house’s interior
• Enhance safety for families and residents

Final Thoughts:

Preparing for future storms means thinking differently about the materials we use in construction. Instead of only using what is cheapest or most familiar, it’s now more important to use materials that can protect homes during extreme weather.

Moisture-resistant drywall is a good first step, but in high-risk areas, homeowners should consider fiberglass-faced boards, cement board, or magnesium oxide panels. Blended with intelligent design elements like top-level outlets, sealed walls, and lower, removable panels, these materials can potentially greatly reduce damage and recovery time after a storm.

FAQ Drywall solutions for future storms:

Q: How do you cover drywall against rain?

A: Keep it stored or covered with plastic or tarps. Place moisture-resistant drywall in wet areas and close joints with water-blocking paint or coatings.

Q: What are the problems with drywall?

A: It soaks up water easily, can grow mold, breaks easily when wet, and may need full replacement after flooding.

Q: How long is drywall good for?

A: If kept dry and undamaged, drywall can last 30–70 years. But water or impact damage shortens its lifespan.

Q: How can drywall damage be repaired?

A: Small holes can be patched with filler. Larger damage may need cutting out the damaged area and replacing it with a new drywall piece.
