Who is behind this website?
Air Sense Environmental is responsible for the services presented on JeffCo Radon. The county-focused name organizes the information for local readers; it is not a separate business location.
Photos are drawn from Air Sense’s provided installation assets. They illustrate equipment and construction details without claiming that the pictured job occurred in Arnold, Festus or another Jefferson County community.
How should you use this information?
A house may have more than one ground-contact area to describe. Use these pages to think through the original basement, a crawl space or an addition before requesting work. The goal is a complete description of the building, supported by its actual radon measurement.
- Include later additions when explaining the layout.
- Locate available access to each foundation area.
- Distinguish an indoor test result from a system indicator.
How do you request a visit?
Phone 314-664-9807 or send a request through the contact page. State whether you need a first test, help discussing a result or an assessment of an existing installation. Include the address so service details can be confirmed for that property.
