Mold Mitigation in St. Louis: Why Speed Matters
If you’ve had a leak, flood, or storm damage, mold isn’t just a possibility—it’s a near guarantee if you don’t act fast. St. Louis weather conditions, especially during the summer, create the perfect breeding ground for mold spores to grow in walls, carpets, basements, and HVAC systems.
At San Juans Restoration, we’ve seen homes overrun with mold in just 48 hours. That’s why we treat every call like an emergency.
How Mold Spreads in Midwest Homes
Mold thrives in dark, damp environments—and it doesn’t take much. After a water intrusion, spores can begin spreading within 24–48 hours. Here’s how it often happens:\n- A roof leak drips into an attic or ceiling insulation\n- Basement floodwaters aren’t fully extracted\n- Humidity builds in a closed-up room without ventilation\n- A washing machine or sink overflow goes unnoticed for hours
In neighborhoods like Florissant, Ballwin, and South City STL, we see a high number of mold cases due to older homes with poor airflow and hidden wall cavities.
Signs of Hidden Mold Damage
Even if you don’t see it, mold could already be growing behind your walls. Warning signs include:\n- Musty or earthy odors\n- Discoloration on drywall or ceilings\n- Allergic reactions like coughing, sneezing, or eye irritation indoors\n- Increased humidity, especially in corners and closets\n- Peeling paint or bubbling surfaces
SJR uses moisture meters and thermal imaging to detect moisture inside your walls—without cutting anything open.

Mitigation Tools Used by SJR
Our certified mold specialists follow a multi-step mitigation process:\n- Containment setup to isolate affected areas\n- Negative air pressure machines and HEPA filtration\n- Removal of mold-infested materials (drywall, insulation, carpet, etc.)\n- Treatment with EPA-approved antimicrobial sprays\n- Dehumidifiers and air scrubbers to clean and dry the air
We finish with a post-remediation inspection and can help arrange third-party clearance testing if needed.
Mold & Your Insurance: What’s Covered?
Many homeowner policies in Missouri will cover mold remediation if it was caused by a covered water event, such as:\n- Storm or roof leaks\n- Burst pipes\n- Appliance failures
However, if mold is considered the result of long-term neglect or poor maintenance, it may not be covered. That’s why quick reporting and documentation matter.
San Juans Restoration provides full inspection reports and photo evidence that support your claim—and we’ll even speak directly with your adjuster.
