Mold growth can silently spread within homes, causing health risks and structural damage if left unchecked. For homeowners in St. Louis, where humidity levels often fluctuate, early mold detection is essential. This article outlines key signs of mold growth, inspection techniques, and preventative measures to protect your home.

1. Common Early Signs of Mold Growth

• Musty Odor: A persistent, earthy smell is often the first indication of hidden mold.

• Visible Discoloration: Black, green, or white patches on walls, ceilings, or floors.

• Water Stains: Stains or discoloration from past water damage can indicate mold behind surfaces.

• Peeling or Bubbling Paint: Moisture trapped within walls can cause paint to peel or bubble.

• Allergy Symptoms: Increased sneezing, coughing, or congestion indoors may signal mold spores in the air.

2. High-Risk Areas to Inspect

• Bathrooms: Check around sinks, tubs, and under tiles where moisture accumulates.

• Basements: Poor ventilation and humidity make basements prone to mold.

• Attics: Roof leaks or insufficient ventilation can create ideal conditions for mold growth.

4. How to Prevent Mold Growth

• Ventilation: Use exhaust fans in bathrooms, kitchens, and laundry rooms.

• Prompt Repairs: Fix leaks and water damage immediately.

• Proper Drainage: Ensure gutters and downspouts direct water away from the home’s foundation.

• Regular Cleaning: Clean areas prone to moisture, such as bathrooms and basements, using mold-resistant products.
