The Hidden Mold Problem in St. Louis Homes
While most homeowners look for mold in basements and bathrooms, the biggest threats are often above and below your living space - in attics and crawl spaces.
In St. Louis, with our humid summers and stormy spring season, it’s the perfect environment for hidden mold to thrive.
Why Mold Grows in Attics & Crawl Spaces
Attics and crawl spaces often lack proper ventilation. When moisture builds from poor drainage, leaky roofs, or HVAC condensation, mold spores settle fast. Most people don’t realize it’s there until:
Their roof shows signs of sagging or rot
Their energy bill spikes due to insulation issues
They begin experiencing unexplained allergies or breathing problems
Warning Signs You Might Have Hidden Mold:
Musty odors rising through vents or floors
Cold spots or soft wood in the attic or crawl space
Insulation that looks wet, discolored, or deteriorating
Past leaks or flooding events, especially near the roofline or foundation
