Who is behind this website?
Air Sense Environmental operates this site and provides the services described. St. Charles County Radon names the geographic focus of the information, not a second contractor or a county office.
Installation photographs come from the provider’s image collection. A pictured pipe or utility room illustrates a component; its inclusion does not establish a St. Charles County job location or a measured outcome.
How should you use this information?
Start with the page that matches your immediate question. A new-home owner can review passive piping, while a homeowner considering sump suction can prepare questions about drainage access. Neither guide replaces an assessment of the actual foundation.
- Save any builder documents about existing vent piping.
- Have the complete test results ready to discuss.
- Identify the sump, basement rooms and accessible equipment.
How do you request a visit?
Use the contact page or dial 314-664-9807 to describe the property. Mention whether the question concerns initial testing, activation of an existing pipe or a new mitigation proposal. Air Sense will need to confirm the appointment details.
