How Mold Affects Children’s Health: What NYC Parents Should Know

Living in New York City means close quarters, high humidity, and older buildings—conditions that make mold a persistent issue in many homes and apartments. While mold is a health concern for anyone, young children are especially vulnerable to its effects.

At Crown Mold Specialists, we’ve worked with many NYC families who discovered that mold exposure was affecting their children’s health—often without realizing it right away. If you’re a parent in the city, understanding how mold impacts kids and what to look out for can help you protect your family’s well-being.

Why children are more sensitive to mold

Children breathe more air relative to their body weight than adults, meaning they inhale more mold spores when present in the environment. Their immune systems are also still developing, which makes them less capable of fighting off allergens, toxins, and irritants released by mold.

Health issues linked to mold exposure in children

1. Respiratory problems
Mold spores can irritate the airways, leading to coughing, wheezing, shortness of breath, or worsened asthma symptoms. Children with pre-existing respiratory conditions are especially at risk.

2. Skin rashes and irritation
Direct contact with mold or mold-contaminated materials can cause itchy, red, or inflamed skin in sensitive children.

3. Allergic reactions
Runny nose, sneezing, eye irritation, and sinus congestion may all result from mold allergies. These symptoms often persist indoors and improve when children are away from home.

4. Increased risk of infections
In rare cases, prolonged exposure to mold—especially toxic black mold—may weaken a child’s immune response, leading to more frequent respiratory infections.

5. Fatigue and difficulty concentrating
Some families report that children exposed to mold at home seem tired, unfocused, or irritable. While these symptoms can have many causes, chronic exposure to indoor mold may contribute.

Where mold hides in NYC homes

Even clean, well-kept apartments can have hidden mold problems. Common mold hotspots include:

  • Behind walls and under floors

  • In poorly ventilated bathrooms

  • Inside closets or behind furniture placed against exterior walls

  • Around windows and HVAC units

  • In basements, laundry rooms, or near plumbing leaks

What NYC parents can do

Look for signs early
Musty smells, condensation, peeling paint, or recurring allergies in your child should prompt a closer look. If you rent, notify your landlord immediately.

Get a professional mold inspection
DIY tests may not catch hidden mold. Our team uses professional-grade tools to detect moisture and mold—even behind walls.

Improve home ventilation
Ensure your home is properly ventilated, especially in bathrooms and kitchens. Use dehumidifiers to keep indoor humidity under 50%.

Act quickly
Don’t wait for visible mold to appear. If your child’s health symptoms line up with other mold signs, it’s best to get your space tested and treated.

Final thoughts

Mold is more than just a nuisance—it can seriously affect your child’s health and quality of life. Fortunately, with the right knowledge and quick action, you can reduce the risk and keep your living space safe.
