What Is Mold? Health Risks & Home Damage

Mold can grow anywhere moisture exists. It's more than just an eyesore — it can harm your health and home.

What Is Mold?

Mold is a type of fungus that spreads through airborne spores. While it’s natural outdoors, its presence indoors signals a problem. Molds can be black, green, or white, and often produce a musty smell. Dark wall spots or unpleasant odors at home may be signs of mold contamination.

Mold flourishes in damp, humid areas, feeding on wood, drywall, fabric, and even dust. If moisture persists, mold colonies can form and cause damage.

Mold as an Indoor Pollutant

According to the World Health Organization (WHO), microbial pollution — including mold — significantly impacts indoor air quality. Long-term exposure to damp environments can increase health risks.

The Centers for Disease Control and Prevention (CDC) also warns against ignoring visible mold or musty odors, as they indicate unhealthy indoor conditions.

Why You Should Care About Mold

Mold presents risks to both your health and home. Even non-allergic individuals may experience irritation in the eyes, skin, or nose. (We’ll explore symptoms in the next article: “How Mold Affects Your Health.”)

Mold typically signals an underlying moisture issue, like leaks or condensation, which can lead to serious structural damage. It may discolor paint, warp wooden beams, and even crumble drywall or ceiling tiles.

Dutch experts highlight that certain wood-decaying molds (like huiszwam) can weaken structural components. Repairs can be costly — prevention is best.

How Common Is Indoor Mold?

You’re not alone. According to the European Environment Agency (EEA), about one in six homes in Europe is affected by mold or dampness.

  • Moist basements
  • Poorly ventilated bathrooms
  • Leaky roofs or pipes
  • Drying laundry indoors

Even new homes can develop mold if airflow is poor. Mold can begin to grow within 48 hours of moisture exposure. Often, mold shows up as “black spots” on ceilings or as a damp smell in basements. Don’t ignore these signs. Health officials recommend removing mold and resolving its moisture source immediately.

Key Reasons to Care About Mold in Your Home

🩺 Health Concerns

Mold releases microscopic spores into the air. Inhaling them can cause:

  • Allergic reactions (sneezing, runny nose, itchy eyes)
  • Asthma attacks
  • Respiratory discomfort

Some types also produce toxins (mycotoxins). Even non-toxic species can harm health in high quantities.

👃 Unpleasant Living Conditions

Mold spreads musty odors and creates unsightly black or green patches. Affected rooms feel damp — even with heating on.

🏩 Property Damage

Mold degrades the materials it grows on. It can:

  • Bubble or peel paint
  • Loosen wallpaper
  • Rot wood or drywall

💧 Moisture Problems

Mold is often a red flag for hidden moisture — like leaks or excess humidity — which can also lead to wood rot or pest infestation.

In Summary

Mold is more than a visual nuisance — it signals an unhealthy home. Leading health bodies (WHO, CDC, EEA, RIVM) stress the importance of keeping indoor spaces dry and mold-free.
