Risk Factors
Prevention Recommendations
Keep indoor humidity below 50% using a dehumidifier, especially in basements and bathrooms. Your area's average outdoor humidity of 67% means indoor levels will naturally run high without active dehumidification.
Run exhaust fans during and 30 minutes after showers. Vent the dryer outdoors. Open windows when weather permits to reduce moisture buildup.
With a median home built in 1972, check for roof leaks, foundation cracks, and plumbing issues. Older homes often have inadequate vapor barriers.
Use a humidity gauge ($10-20) in bathrooms, basements, and crawl spaces. Act quickly on musty odors, condensation on windows, or visible dark spots on walls and ceilings.
If you suspect mold, hire a certified mold inspector ($200-600). DIY testing kits are unreliable. A professional inspection may assess moisture and hidden growth; sampling is used when appropriate.
Control Indoor Humidity
Keep indoor humidity below 50% when possible and fix leaks promptly to reduce mold growth. A dehumidifier can help control humidity in damp areas.
hOmeLabs 50-Pint Dehumidifier - ~$230 →Mold Risk in Glenwood, NJ
ZIP code 07418 shows moderate mold risk with a score of 45/100. Some environmental factors — including 67% average humidity — create conditions where mold can develop without proper moisture management.
Why Mold Matters
Indoor mold exposure affects approximately 4.6 million asthma cases in the U.S. annually, according to EPA estimates. Health effects include:
- Allergic reactions — sneezing, runny nose, red eyes, skin rash
- Asthma triggers — mold can trigger asthma symptoms in sensitive people, including children
- Respiratory effects — dampness and mold exposure are associated with sinus and bronchial symptoms
- Property damage — untreated mold degrades drywall, wood framing, and insulation
Humidity Profile for 07418
The annual average relative humidity in this area is 67%. Sustained indoor humidity above 60% can encourage mold growth, and leaks or wet materials can also support it.
Summer humidity averages 69%, creating peak mold risk conditions from May through September. Air conditioning helps by reducing humidity, but condensation on ductwork and drip pans can become mold sources if not maintained.
Housing Age Factor
The median home in ZIP 07418 was built in 1972. Homes from this era may have some moisture management gaps, particularly around older windows, bathrooms, and crawl spaces.
Flood History
This area has 1 NFIP flood insurance claims, indicating water intrusion events that create ideal mold conditions. After flooding, mold can begin growing within 24-48 hours on wet building materials. Even occasional flooding can leave hidden moisture in wall cavities and under flooring.
About This Assessment
This mold risk score combines NOAA humidity data, Census housing age data, FEMA NFIP flood claim records, and EPA water system violation data. Individual home mold risk depends heavily on maintenance, ventilation, and past water damage events not captured in area-level data.

Frequently Asked Questions
What factors increase mold risk?
Indoor humidity above 60%, poor ventilation, past water damage, and moisture intrusion can increase mold risk. Basements, crawl spaces, and bathrooms without exhaust fans are the most common problem areas. Flooding or persistent indoor moisture can raise mold risk in a home.
How do I know if I have mold?
Common signs include a persistent musty smell, visible discoloration on walls or ceilings, and allergy symptoms (sneezing, itchy eyes, congestion) that worsen indoors. Check behind furniture, under sinks, and around windows for hidden growth. If you suspect hidden mold, a professional inspection ($300–$600) can investigate moisture and possible hidden growth.
How much does mold remediation cost?
Professional mold remediation typically costs $500–$6,000 depending on the affected area and severity. Small patches (under 10 sq ft) can often be cleaned with household products. Larger infestations may call for containment, HEPA cleaning, material removal, and help from a qualified professional. Most homeowner insurance policies do not cover mold unless it resulted from a covered event like a burst pipe.
