Radon Testing · $165
Measure an Invisible Risk Before Closing
Radon cannot be seen or smelled. Professional testing provides property-specific information so buyers and homeowners can decide whether further action is appropriate.
What the Service Includes
Professional Test Setup
Testing equipment is placed in an appropriate area of the home according to the selected protocol and property conditions.
Documented Results
You receive results that explain the recorded level and the practical next step when additional evaluation or mitigation is warranted.
Who Should Test
- Home buyers who want property-specific information before completing a purchase.
- Homeowners who have never tested or whose home has changed significantly.
- Owners testing after mitigation, major renovations, or changes to the lowest occupied level.
Plan radon testing around your inspection deadline
Radon testing can be coordinated with a residential home inspection. Share the property address, inspection deadline and access arrangements when requesting the service. Ask TMK to confirm the test period, setup arrangements and expected delivery of results before choosing an appointment.
The EPA’s Home Buyer’s and Seller’s Guide to Radon calls for at least 48 hours of measurement; some devices require longer. Allow time for setup, results and any recommended follow-up before your inspection deadline.
Help the occupants prepare
For a short-term test lasting 2–4 days, EPA guidance calls for closed-house conditions beginning at least 12 hours before testing and continuing throughout the test. Keep windows shut, use exterior doors for normal entry and exit, and leave the equipment undisturbed. Follow TMK’s full instructions for the selected protocol, including ventilation and any existing mitigation system. Tell TMK if testing conditions change so they can be reviewed.
Why Conditions Matter
Radon levels can vary from one property to the next. Foundation type, air movement, weather, and building conditions can influence results, which is why testing the actual home is more useful than relying on neighborhood averages.
Frequently Asked Questions
How much does radon testing cost?
TMK’s radon testing service is $165.
Can radon testing be added to a home inspection?
Yes. It is commonly scheduled with a residential inspection. Tell us when booking so we can coordinate timing and access.
What does an elevated radon result mean?
Radon results are reported in picocuries per liter (pCi/L). The EPA recommends reducing radon when the level is 4 pCi/L or higher and considering reduction between 2 and 4 pCi/L. A lower result does not establish a risk-free level.
TMK explains the recorded level and the practical next step, which may include further evaluation by a qualified radon-mitigation professional. Discuss the result and any recommended follow-up before your inspection deadline. Radon testing does not include mitigation.
Can occupants disrupt a test?
Test protocols require appropriate closed-building conditions and equipment that remains undisturbed. We explain the requirements when scheduling.
