Mold After the Storm: Why St. Louis Homes Are at Risk and How to Stop It Early
After a heavy storm, most homeowners look for obvious roof damage or flooding. But what many miss is the slow, quiet threat that starts inside walls, attics, and basements: mold.
In humid regions like St. Louis, just 24–48 hours of trapped moisture is enough for mold spores to activate. And if you don’t catch it early, it spreads fast.
Common Post-Storm Mold Triggers
Leaky roofs or attic condensation
Flooded basements or crawlspaces
Wet drywall, flooring, or insulation
Poor ventilation after water intrusion
Even minor leaks around windows or flashing can lead to hidden colonies that impact air quality and cause wood rot over time.
Signs You Might Already Have Mold
A musty smell, especially after storms
Allergies or respiratory issues indoors
Dark spots or stains on ceilings/walls
Peeling paint or warping surfaces
If your home has had recent leaks and now smells “off,” mold could already be present behind the scenes.
Why DIY Isn’t Enough
Bleach and surface sprays don’t solve real mold problems. In fact, they often just discolor visible spots while the roots remain active inside your walls or subfloor.
