What should you include in your request?
Give the street address and community, such as St. Peters, Wentzville, Cottleville or Lake Saint Louis. If the inquiry is about new construction, say whether the builder left radon documents or labeled piping. Include a callback number and any approaching inspection date.
- Address of the St. Charles County property
- Existing report with every page included
- Builder notes or photos of labeled vent piping
- Sump location and basement access details
- Date by which you need the next step confirmed
What needs to be confirmed before the visit?
Ask which parts of the house must be accessible and whether the appointment is for a measurement or an installation assessment. Sending a request starts the scheduling discussion; wait for direct confirmation of the visit and its scope.
For an occupied home or a purchase, arrange entry with the owner or responsible representative. Follow the testing professional’s preparation instructions rather than making changes around the equipment on your own.
Have a report already?
A report is most useful when it includes the measurement dates and room location. Keep those pages together. If an existing system is involved, provide its available installation records too; a photo of the gauge alone cannot establish the indoor radon concentration.
