Search for local professionals with active radon certifications and ask which test method they use for your situation, including short-term kits or continuous radon monitors.
DIY kits are usually the lowest-cost option, while professional testing costs more but often includes setup, chain-of-custody handling, and documented results for real estate needs.
Yes. Testing during the inspection period helps you make informed decisions and can support negotiation if levels are elevated.
Turnaround depends on test type and lab processing. Continuous monitors can provide readings quickly, while mailed short-term kits take longer due to lab transit.
Confirm the result as needed and start comparing local mitigation contractors right away so you can move from testing to reduction without delay.
