Everything You Need to Know About Drywall

Drywall, also known as plasterboard, sheetrock, or wallboard, is a critical component in the construction of most modern homes. It’s used primarily for interior walls and ceilings as a time-efficient and cost-effective alternative to traditional lath and plaster. Despite its widespread use, drywall is not impervious to damage, particularly water damage, which can compromise both its appearance and structural integrity.

What Happens When Drywall Gets Wet?

When drywall gets wet, it can lead to serious issues. One of the primary problems is that wet drywall can expand significantly—up to ten times its original size. As it expands, the drywall loses its strength, making it prone to sagging, breaking, or even collapsing. This not only undermines the structural integrity of your home but can also create safety hazards.

Moreover, water-damaged drywall is highly susceptible to mold growth, which can be harmful to your health and require costly remediation. Toxic black mold, in particular, can develop on or behind wet drywall, creating an unsafe living environment.

Should You Replace Wet Drywall?

If your drywall has been exposed to water, you may wonder whether it’s better to repair or replace it. The answer depends on the extent of the water damage.

Testing for Moisture: To assess the damage, you can use moisture meters—either non-penetrating or penetrating. A non-penetrating moisture meter will give you a general idea of the moisture levels, while a penetrating meter can provide a more accurate reading by measuring moisture inside the wall. Alternatively, you can use a screwdriver to test the drywall’s integrity; if it easily penetrates the surface, the moisture content is high, and replacement is likely necessary.

Replacement vs. Repair: If the drywall is severely compromised, it’s best to replace it entirely, along with any affected insulation. This approach helps prevent future problems, such as structural weaknesses or mold growth. However, if the exposure to water was minimal and the moisture hasn’t penetrated deeply, you may be able to repair the drywall by cleaning, sanding, and repainting the affected area.

How Long Does It Take to Dry Out Water Damage?

The drying time for water-damaged drywall varies based on several factors, including the drying methods used and the local climate. In dry, desert-like conditions, drywall will dry out faster, especially with the use of industrial fans and dehumidifiers. Conversely, in humid climates, the drying process may take longer.

To speed up the drying process, consider removing baseboards and sealing the room while running high-quality dehumidifiers and fans. However, if mold is present, the drying process will need to be followed by mold removal and remediation.

How Do You Fix Drywall That Got Wet?

The process for repairing water-damaged drywall depends on the severity of the damage:

Minor Damage: For minimal water exposure, you can start by cleaning the affected area and scraping off any flaking paint. Sand the area smooth, then prime and repaint the surface. This process should restore the drywall’s appearance and integrity if the damage is not too severe.

Extensive Damage: For more extensive water damage, where the drywall has become soft or moldy, complete replacement is often the best option. Replacing the drywall ensures that all compromised materials are removed, preventing future issues.

Is Repairing Drywall Worth It?

If your drywall has been exposed to significant amounts of water or has been wet for more than 30 minutes, replacement is generally the best course of action. Attempting to repair severely damaged drywall can lead to future problems, including mold growth and structural instability.

In cases where mold is present, it’s essential to hire a professional to handle the removal and replacement process. A skilled contractor can safely remove the damaged drywall without spreading mold spores, ensuring a safe and effective repair.
