Water damage to drywall is a frequent issue in households. When drywall absorbs water, it creates an environment conducive to mold growth, leading to additional damage. Whether the water damage stems from a roof leak, air conditioner malfunction, flooding, or another source, it’s integral to address repairs promptly. 

According to HomeAdvisor, repairing drywall costs approximately $500 on average, with variations depending on the extent of damage. Repairing damage promptly is more economical than replacement. Therefore, addressing water damage immediately can save money by preventing further deterioration that may necessitate costly replacement.

Furthermore, damp drywall can compromise your home’s structural integrity. Although drywall itself isn’t load-bearing, its deterioration can adversely affect surrounding structures, leading to significant issues and potentially creating unsafe conditions for occupants it is because drywall becomes an ideal breeding ground for harmful bacteria and mold, posing potential health risks.

The Safe Moisture Levels in Drywall

In our homes, the moisture level can vary, with humidity typically hovering around 50%. But when When it comes to drywall, it’s essential to maintain the right moisture balance for safety. So, what exactly is the safe level of moisture for drywall?

Drywall is considered safe when its moisture content falls between 5% and 12%. Even if the moisture level creeps up to 17%, the drywall can still be salvaged. However, any moisture level beyond 17% indicates significant damage, rendering the drywall unusable and necessitating replacement.

A Simple Guide to Identifying Wet Drywall

Examine its color

Look for discolored patches on the wall where the paint used to be white – this could indicate water stains.

Inspect for signs of mold growth

Mold thrives in damp spots like bathrooms, kitchens, basements, and crawl spaces, and can even hide under wallpapers. Pay close attention to areas near ceilings and walls, where visible mold might be present.

Scrutinize the flooring

Cracks or holes may suggest moisture seepage from the subfloor. Look for dry rot where the flooring meets the walls – if you find any, replace the affected wood promptly.

Assessing Moisture Levels Using Moisture Meter

Following a flood, gauging the moisture content in affected areas provides valuable insight into the extent of water damage. This assessment, particularly concerning drywall, lays the groundwork for restoring your home to its pre-damage condition.

Professionals employ various types of moisture meters to measure drywall moisture, including:

1. Pin-type meter: Equipped with probes or pins, this meter measures the moisture content of drywall and other affected materials.

2. Pinless moisture meter: Commonly used for assessing moisture in flooring, this meter operates without probes.

3. Thermo hygrometer: Designed to measure relative humidity, this device provides a comprehensive overview of moisture levels in affected areas.

Where Else Could Moisture Linger?

Whether facing a burst pipe or a severe weather event, understanding the extent of moisture after the incident is needed for assessing the water damage restoration process. Moisture tends to lurk in various places such as drywall, wood, carpeting, and other surfaces. Here are the key areas where moisture commonly hides following a flood:

Carpeting

Those who have encountered water damage in carpeted areas understand how saturated both the carpeting and padding can become. Even when efforts are made to dry out the carpeting, residual moisture may persist, fostering mold growth and other issues over time.

Wood Floors

Ideally, the moisture content of wood in interior spaces should range from 6% to 8%. However, post-flood, moisture levels can skyrocket to over 20%. With the aid of dehumidifiers and drying equipment, wood can gradually return to an acceptable moisture level over time.

Furniture

Furniture, with its combination of fabric, cushions, and wood components, is a magnet for hidden moisture. The drying process for large pieces of furniture can be prolonged due to the materials involved.

Ceilings

Often composed of drywall or similarly permeable materials, ceilings are susceptible to water damage, especially in cases of roof leaks. Elevated moisture readings may signal the need for removal and replacement of affected ceiling sections.

Early Detection & Professional Aid in Drywall Water Damage

It’s important to know effective methods for identifying water damage in drywall because early detection allows for prompt action to prevent further damage and mitigate potential health hazards associated with mold growth.

FAQs

How long does it take for water to leak through drywall?

The time it takes for water to leak through drywall can vary depending on factors such as the amount of water, the severity of the leak, and the condition of the drywall. In some cases, water may start seeping through relatively quickly, especially if the drywall is already compromised or if there’s a significant amount of water present. However, it may take several hours or even days for noticeable signs of water damage to appear on the surface of the drywall.

Does wet drywall always need to be replaced?

While wet drywall can often be dried out and salvaged, it ultimately depends on the extent of the water damage. If the drywall is only slightly damp and the damage is caught early, it may be possible to dry it out effectively and avoid replacement. However, if the drywall is extensively saturated, shows signs of mold growth, or has been exposed to contaminated water, replacement may be necessary to prevent further damage and ensure the safety of the building occupants.

How do you know if drywall has water damage?

Several signs indicate drywall has water damage. These include discoloration or staining on the surface of the drywall, peeling or bubbling paint or wallpaper, a musty odor, soft or sagging areas, and visible mold growth. Additionally, if the drywall feels damp to the touch, it likely has water damage. It’s important to inspect the drywall thoroughly, including areas that may be hidden from view, such as behind furniture or in closets, to identify any potential water damage.

How much water can drywall absorb?

A drywall can absorb a significant amount of water, especially if it is not properly sealed or if the water exposure is prolonged. On average, drywall can absorb up to 15% of its weight in water. However, once saturated, drywall becomes weakened and may lose its structural integrity. It’s essential to address water damage promptly to prevent further absorption and potential damage to the drywall and surrounding structures.
