Mold Detection: Signs, Health Risks & Remediation Steps

Identifying Mold in Your Home

Visible & Olfactory Clues

  • Fuzzy/cottony patches: black, green, white, orange
  • Persistent musty, earthy odor

Health Symptoms

  • Allergic: sneezing, rhinitis, itchy eyes, skin rash
  • Respiratory: cough, wheeze, asthma exacerbation
  • Severe: hypersensitivity pneumonitis, invasive infection (immunocompromised)

Moisture Sources

  • Roof/pipe leaks, condensation, flooding, high humidity (>60%)

Action Plan

  1. Find & Fix Moisture Source – essential; mold returns without it.
  2. Clean Small Areas (<10 sq ft): Detergent + water, or 1 cup bleach/gallon water (never mix with ammonia). Wear N95, gloves, goggles.
  3. Discard Porous Materials: Moldy drywall, carpet, insulation, ceiling tiles.
  4. Dry Thoroughly: Dehumidifiers, fans, ventilation.
  5. Prevent Recurrence: Maintain <60% RH, exhaust fans, prompt leak repair.

When to Hire Professionals

  • >10 sq ft contamination
  • HVAC system involvement
  • Sewage/black water source
  • Occupants with high‑risk health conditions
