How to Check for Mold in Your Home

Mold may have subtle signs that make it hard to detect without inspection. Even if you don’t suspect mold damage Sonoma County in your home, performing a simple annual check and keep your home protected and mold free, helping you and your family avoid the risks of mold exposure.

Perform a Visual Inspection

Start by examining areas of your home where mold is most likely to grow. Mold thrives in damp, dark environments, so check for mold warning signs in:

  • Bathrooms (around sinks, showers, and bathtubs)
  • Kitchens (under sinks, inside cabinets)
  • Basements and crawl spaces
  • Attics with poor ventilation
  • Areas with past water damage
  • Around windows and air conditioning vents

Mold can appear as black, green, white, or even pink spots on walls, ceilings, and floors. If you notice discoloration or fuzzy growth, there’s a strong chance mold is present.

Look for Water Damage and Moisture

Mold needs moisture to grow. If your home has a history of water damage from leaks or flooding, check for:

  • Water stains on ceilings or walls
  • Warped or peeling wallpaper/paint
  • Soft or rotting wood
  • Condensation on windows or pipes

A moisture meter can help detect hidden damp areas where mold might be growing behind walls or under flooring.

Test Indoor Air Quality

Mold spores can become airborne, leading to poor indoor air quality. Professionals use air sampling tests to compare indoor air quality to outdoor air. However, you can also conduct a simple DIY test using:

  • Home mold test kits (available online or in hardware stores)
  • HVAC filter checks: if your filters are clogged with dust and black particles, it could be a sign of mold contamination

Check for Musty Odors

Mold often has a distinct, musty smell. If you notice a persistent earthy odor, especially in basements, attics, or enclosed areas, it could indicate hidden mold. Even if you can’t see it, the smell alone is enough reason to conduct further inspection. In extreme cases, mold infestations may require professional odor removal for complete remediation.
