Should you get a radon test with a home inspection?
Yes. A radon test supplies information a visual inspection cannot provide. EPA recommends testing a home before purchase. An attractive basement, a newer foundation or a neighboring property's result cannot establish the number in the home you are buying.
Ask for any previous report when you order the inspection. Check which level was tested and whether the property has changed since then. This gives your tester useful context without treating an old result as a current measurement.
Does a home inspection include a radon test?
A home inspection includes radon testing only when the inspection agreement specifically includes that service. Confirm the scope with your inspector instead of assuming a radon result will appear in the general inspection report.
- Who is ordering and paying for the radon test?
- Who will authorize entry and equipment collection?
- Which parties need a copy of the completed report?
How long does a radon test take for a home inspection?
The test duration and the report delivery time are separate parts of the schedule. Short-term transaction testing commonly requires at least 48 hours of measurement, with preparation, placement, pickup and reporting arranged around it. Air Sense must confirm the actual schedule for your property.
Provide the inspection-response deadline, not only the closing date. A result delivered before closing may still arrive too late for the contract's inspection process. Leave room for an invalid test to be repeated if necessary.
Can you be in the house during a radon test?
People can generally remain in the house during a radon test while following the tester's written instructions. Normal entry and exit are different from leaving exterior doors or windows open. Keep the device in its assigned location.
- Tell every occupant when testing begins and ends.
- Share the instructions with agents and showing contacts.
- Report an interruption rather than trying to correct the data yourself.
Do you need a radon test with no basement?
Yes. Homes built on slabs or above crawl spaces can also have radon. The absence of a basement does not eliminate the need for a property-specific measurement. Tell the tester about additions, split levels and any space you expect to use regularly.
How is a real estate radon test protected from tampering?
A defensible real estate test starts with documented placement and clear instructions. EPA describes measures such as occupant agreements and tamper indicators. Ask which checks will be used for your test and how an interruption would be handled.
A surprising number alone does not demonstrate tampering. Review the test conditions and the report with the measurement professional before drawing conclusions.
How much does a radon inspection cost?
The radon inspection price should cover the agreed measurement and reporting scope. Ask Air Sense for a property-specific quote at 314-664-9807. A general testing starting price is not a promise about a transaction requiring extra devices, access arrangements or reporting.
- Confirm placement and pickup are included.
- Identify the report recipients before scheduling.
- Ask how a repeat visit would be charged.
Questions before you book
Can a seller order a test before listing?
Yes. A seller can arrange testing before listing and keep the report with the property records. A buyer may still request a new measurement.
What should I send when requesting a test?
Send the address, property type, inspection deadline, access contact and any existing radon report. Include whether a mitigation system is already installed.
