Indoor Air Quality in Ballwin, MO

An indoor air quality test in Ballwin, MO is a 48-hour continuous monitoring assessment, not a spot check. Air Sense Environmental records particulates, VOCs, CO2, CO, temperature and humidity in Ballwin homes at one-minute intervals and turns the data into a written report with specific fixes.
What does an indoor air quality test measure in a Ballwin home?
- Particulate matter (PM2.5 and PM10) from cooking, candles, smoke and HVAC systems
- Chemical vapors (VOCs) from paints, cleaners, new flooring and furniture
- Carbon dioxide and carbon monoxide, which point to ventilation and combustion problems
- Temperature and relative humidity; sustained humidity above 60 percent is a warning sign
- Radon (optional), measured against the EPA action level of 4.0 pCi/L
When should Ballwin homeowners test indoor air quality?
Ballwin sits on the rolling upland of west St. Louis County, where clay-heavy soils over limestone bedrock hold radon in the ground until a house draws it in. These are the situations and Ballwin home types where a test pays off:
- Allergy or respiratory symptoms that ease when you leave the house
- After a renovation, new flooring or new furniture
- Humidity that stays high, or a musty smell from a basement or crawl space
- Before buying or selling a home
- Split-level and two-story homes from the 1960s to 1990s subdivisions off Manchester Road, most with full basements
- Walkout-basement homes on the hillier lots toward Castlewood State Park
How does indoor air quality testing work in Ballwin?
- Monitor placement. One or more continuous monitors go in the rooms where the family spends its time.
- 48 hours of data. Readings are logged at one-minute intervals through normal daily life.
- Written report. You see each pollutant against its healthy range, with the specific fix for anything outside it.
What happens after the indoor air quality results?
The report names the problem, and Air Sense Environmental installs the fix it calls for: an AprilAire whole-home dehumidifier for high humidity, an energy recovery ventilator for stale air and rising CO2, or a radon mitigation system when radon is at or above 4.0 pCi/L. The main indoor air quality testing page covers the equipment and the full process.
How much does indoor air quality testing cost in Ballwin, MO?
Pricing depends on the size of the Ballwin home and how many monitoring locations it needs; most single-family homes need one or two monitors. Call 314-664-9807 for a free consultation and an exact quote.
