Mold After Storms: St. Louis Risks & How to Stop It Early

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.

Absolute Restoration and Roofing uses professional-grade equipment to:

• Identify moisture hotspots with infrared and hygrometers

• Contain affected areas to stop airborne spread

• Remove damaged materials and treat exposed framing
