Flemington, NJ —

A recent inspection has uncovered mold growth in 33 classrooms across Hunterdon County schools in New Jersey, according to local news reports. The discovery has prompted school officials to take action and left many parents wondering about the safety of school buildings—and their own homes.

Mold in schools is more common than many people realize. Older buildings, combined with humidity and occasional water intrusion from leaks or storms, can create the perfect conditions for mold to grow. When mold is found in a school setting, it often raises questions about whether similar problems might exist in homes throughout the community.

What We Know About the Hunterdon County Discovery

According to mycentraljersey.com, mold was found in 33 classrooms within Hunterdon County schools. While the full scope of the situation is still developing, discoveries like this typically prompt building assessments, remediation efforts, and communication with families.

Hunterdon County, located in western New Jersey, has a mix of older and newer school buildings. Many structures in the region date back decades, and aging infrastructure can sometimes lead to moisture problems that allow mold to take hold.

Why Mold in Schools Matters for Homeowners

When mold is discovered in public buildings, it often serves as a wake-up call for the surrounding community. The same weather patterns, humidity levels, and building materials that contribute to mold in schools can also affect homes in the area.

New Jersey experiences humid summers and can see significant rainfall throughout the year. These conditions, combined with older housing stock in many communities, mean that mold can easily develop in basements, bathrooms, attics, and areas around windows where moisture tends to collect.

Parents who are concerned about mold exposure at school should also consider whether their own homes might have hidden mold problems. Common signs include:

  • Musty or earthy odors, especially in basements or closets
  • Visible dark spots on walls, ceilings, or around windows
  • Recent water damage from leaks, flooding, or burst pipes
  • Condensation on windows or walls
  • Peeling paint or wallpaper that seems damp

How Mold Grows and Spreads

Mold needs three things to grow: moisture, warmth, and organic material to feed on. Drywall, wood, carpet, and even dust can provide food for mold spores. Once mold starts growing, it releases spores that can settle on other surfaces throughout a building.

The EPA notes that controlling moisture is the key to controlling mold. This means fixing leaks promptly, ensuring good ventilation in bathrooms and kitchens, and addressing any water intrusion as quickly as possible.

Steps Homeowners Can Take

If news of mold in local schools has you concerned about your own home, there are several steps you can take:

  • Inspect your home visually. Look for signs of water damage or visible mold growth, especially in areas that tend to be damp.
  • Check humidity levels. The EPA recommends keeping indoor humidity below 60 percent, ideally between 30 and 50 percent.
  • Fix leaks immediately. Even small drips can create conditions for mold to grow over time.
  • Test for mold. If you suspect mold but cannot see it, testing can help confirm whether spores are present on surfaces in your home.

MycoTest's state-by-state environmental hazard map shows elevated risk in New Jersey due to the state's dense older housing stock and humid climate.

Frequently Asked Questions

How do I know if my home has mold after hearing about mold in schools?

Look for visible signs like dark spots on walls, musty odors, or areas with past water damage. If you suspect hidden mold, a surface sampling test can detect settled mold spores even when growth is not visible to the eye.

Can mold in a school affect my child even if our home is mold-free?

Children can be exposed to mold spores while at school if mold is present in the building. School officials typically address mold problems through professional remediation. If you have concerns, contact your school district for information about their inspection and cleanup efforts.

What should I do if I find mold in my home?

Small areas of mold (less than about 10 square feet) can often be cleaned by homeowners using soap and water or a diluted bleach solution. Larger areas or mold in HVAC systems should be handled by a professional remediation company. Testing before and after cleanup can confirm the mold has been addressed.
