If you suffer from frequent sinus infections, the cause might be hiding in your home—not just your immune system. In many New York City apartments and buildings, indoor mold is a hidden contributor to chronic sinus issues that are often misdiagnosed or left untreated.
At Crown Mold Specialists, we often receive calls from NYC residents who are struggling with ongoing congestion, facial pressure, and headaches—only to discover mold was the root of the problem. Here’s what you need to know about the connection between mold and sinus infections.
How mold affects your sinuses
Mold releases tiny spores into the air, which can be inhaled and trigger irritation in the nasal passages. For some people, this exposure leads to chronic inflammation, blocked sinuses, and even fungal sinus infections.
This is especially common in NYC homes with:
-
Poor ventilation
-
Window condensation
-
Leaky pipes or ceilings
-
Hidden mold behind walls or under flooring
Symptoms of mold-related sinus issues
-
Persistent nasal congestion
-
Facial pain or pressure
-
Post-nasal drip
-
Headaches
-
Coughing or sneezing
-
Symptoms that improve when you leave your home
If you’ve seen multiple doctors, taken allergy meds, or used nasal sprays without lasting relief, mold exposure might be worth investigating—especially if symptoms return when you’re indoors.
Who’s most at risk?
-
Individuals with asthma, allergies, or other respiratory conditions
-
Children and seniors with weaker immune systems
-
People living in high-humidity or water-damaged environments
What you can do
Check your living space
Look for musty odors, discolored walls, or areas prone to moisture—like bathrooms, kitchens, and closets. Mold may be hidden behind drywall or under flooring.
Improve air quality
Use HEPA air purifiers, open windows when weather allows, and run exhaust fans in high-humidity areas.
Control indoor humidity
Keep indoor humidity levels below 50% using a dehumidifier, especially in basements or window-heavy rooms.
Schedule a professional inspection
If you’ve ruled out medical causes and suspect your environment is affecting your sinuses, our team can conduct a mold assessment to find hidden issues.
Final thoughts
If you’re dealing with repeated sinus infections and can’t figure out why, mold might be the missing piece of the puzzle. Getting rid of hidden mold in your NYC home can relieve sinus pressure and improve your overall health.
