When was the last time you thought about the air inside your home?
For most of us, indoor air is an afterthought—even though we spend nearly 90% of our time inside. Whether you’re in a historic Charleston home or a modern new build along the South Carolina coast, the air you breathe could be harboring pollutants that affect your health and quality of life.
Here in Charleston and surrounding South Carolina communities, professional indoor air quality testing can uncover hidden hazards and help you create a cleaner, healthier home. One of the first questions many homeowners ask us is: How much does indoor air quality testing cost? Let’s take a closer look.
Why Indoor Air Quality Testing Matters in the Lowcountry
South Carolina’s warm, humid climate is ideal for mold growth, and older homes in Charleston are more likely to contain outdated building materials that may harbor asbestos, lead, or other environmental hazards. Even new homes are not immune—many contain volatile organic compounds (VOCs) from flooring, paint, cabinetry, and adhesives that linger in the air long after construction is complete.
Common indoor pollutants include:
- Mold spores
- Lead dust
- Volatile Organic Compounds (VOCs)
- Dust mites, pet dander, and allergens
Over time, these contaminants can contribute to chronic allergies, respiratory issues, fatigue, and other unexplained health problems. Testing your indoor air is the first step toward restoring a safe and comfortable living environment.
What Impacts Indoor Air Quality Testing Cost?
Several factors influence how much you’ll pay for IAQ testing in the Charleston area:
1. Type of Pollutants Being Tested
Different tests have different requirements and costs:
- Mold testing may involve air sampling and surface swabs sent to a lab.
- Lead testing may involve dust wipe samples or surface evaluations.
The more pollutants you need tested, the higher the overall cost.
2. Size of the Home
A larger home means more sampling locations and longer inspection times. A modest bungalow may only require a few samples, but a multi-story home with an attic or crawlspace might need a full-panel assessment.
3. Age and Complexity of the Property
Older homes in Charleston’s historic districts often require more in-depth inspection due to legacy materials and complex layouts. Homes with additions or known water damage may also require expanded testing.
4. Urgency
Need your results fast? Rush analysis and expedited lab processing often carry an added fee—especially in real estate transactions or after water damage.

When Should You Consider Indoor Air Quality Testing?

- You experience unexplained allergies, headaches, or respiratory issues at home.
- Your home smells musty or has visible mold growth.
- You’ve had recent flooding or water damage.
- You’ve recently completed a remodel or renovation.
