Is Your Home Making You Sick?

Is Your Home Making You Sick? What You Need to Know About Indoor Air and Mold Testing

If you or your family members have been experiencing unexplained allergy symptoms, headaches, fatigue, or respiratory issues, you may be wondering: Could my home be making me sick? Many people consider air testing for mold as a first step, but according to experts, this may not always be the best approach.

The Connecticut Department of Public Health (CT DPH) advises that air testing for mold is often unnecessary and can even be misleading. Instead, the key to improving indoor air quality starts with identifying and fixing the underlying causes of poor air quality.

Why Air Testing for Mold Might Not Be Helpful

1. No Set Standards for “Safe” or “Unsafe” Mold Levels
Unlike carbon monoxide or radon, there are no official health-based guidelines for acceptable mold levels in homes. Some people are more sensitive to mold than others, so test results alone don’t always explain health symptoms.

2. Testing Won’t Tell You the Source of the Problem
Mold spores are naturally present in all indoor spaces, meaning a test will almost always detect some level of mold. However, the real issue isn’t whether mold is present—it’s whether moisture issues are creating unhealthy mold growth.

3. Testing Won’t Solve the Problem
Even if a test detects mold, it won’t tell you what’s causing it or how to fix it. Instead of spending money on unnecessary testing, experts recommend a simple, practical approach: Find and fix moisture problems first.

Signs Your Home Could Have an Indoor Air Problem

• Musty smells that don’t go away
• Visible mold growth on walls, ceilings, or furniture
• Condensation or high humidity inside your home
• Frequent water leaks from pipes, roofs, or basements
• Worsening allergies, asthma, or respiratory symptoms

What to Do If You Already Have an Ice Dam
What You Should Do Instead of Testing

If you suspect mold or poor indoor air quality is affecting your health, try these steps before paying for air testing:
• Talk to your Medical provider – They can help you see if your symptoms are related to mold. Understanding How Doctors Treat Mold-Related Illness Differently & Choosing a Doctor that’s Right for You
• Inspect Your Home – Look for leaks, water damage, and visible mold.
• Fix Water Problems Quickly – Repair leaks, clean up water spills, and use dehumidifiers in damp areas.
• Improve Ventilation – Open windows when possible, use exhaust fans, and ensure HVAC filters are clean.
• Remove Water-Damaged Materials – Discard soaked carpets, ceiling tiles, and insulation that may harbor mold.
• Choose Low-Emission Cleaning Products – Harsh chemicals can worsen air quality, so opt for safer alternatives.

When Is Air Testing Useful?

In some cases, air testing may help if:
• A professional has already identified a possible mold source, and testing can confirm its spread.
• You need documentation of contamination for a landlord, insurance claim, or legal case.
• There are multiple suspected pollutants (not just mold) contributing to indoor air quality issues.

Don’t Test First—Fix First!

If you believe your home is making you sick, air testing for mold should not be your first step. Instead, focus on identifying and eliminating moisture issues, improving ventilation, and reducing potential irritants. If symptoms persist despite these changes, consider consulting an indoor air quality specialist.
