How Water Damage From Storms Affects Drywall and What to Do

Water damage is one of the most common—and costly—issues homeowners face. Whether it's caused by a roof leak, plumbing failure, overflowing appliance, or flooding, drywall is often one of the first materials affected. Acting quickly can minimize damage, reduce repair costs, and help prevent mold growth.

How Water Damages Drywall
Drywall is made of a gypsum core wrapped in paper. While it's durable under normal conditions, it readily absorbs moisture. As drywall becomes saturated, it can:
•    Stain or discolor
•    Swell or soften
•    Sag or warp
•    Bubble or peel paint
•    Develop mold or mildew
•    Lose its structural strength

Even if the surface appears dry, moisture can remain trapped inside walls, creating conditions for mold growth and additional damage.

Common Causes of Water Damage
•    Roof leaks
•    Burst or leaking pipes
•    Appliance leaks (dishwashers, refrigerators, washing machines)
•    Ice dams
•    Foundation or basement water intrusion
•    Overflowing sinks, tubs, or toilets
•    Storm or flood damage

What to Do Immediately
1. Stop the Source
Identify and stop the leak as quickly as possible. Shut off the water supply if necessary or contact a qualified professional.

2. Dry the Area
Use fans, dehumidifiers, and proper ventilation to remove moisture. The sooner materials dry, the less likely mold is to develop.

3. Inspect the Damage
Look for:
•    Soft or crumbling drywall
•    Water stains
•    Bulging walls or ceilings
•    Mold or musty odors
•    Damage to insulation behind the drywall

4. Determine Whether Repair or Replacement Is Needed
Minor Damage
If drywall has only been slightly damp and dries quickly, repairs may include:
•    Stain-blocking primer
•    New texture if needed
•    Repainting

Moderate to Severe Damage
If drywall has become soft, swollen, moldy, or structurally compromised, the damaged sections should be removed and replaced. Wet insulation should also be evaluated and replaced if necessary.

Signs It's Time to Replace Drywall
•    Drywall feels soft or spongy
•    Ceiling begins to sag
•    Visible mold growth
•    Persistent musty smell
•    Paint continues to bubble after drying
•    Cracks or deterioration around the damaged area

Prevent Future Problems
•    Repair leaks promptly.
•    Inspect plumbing and roofing regularly.
•    Maintain gutters and downspouts.
•    Use dehumidifiers in damp basements.
•    Address small water issues before they become major repairs.
