Burlington, Vermont sits in a region with naturally occurring granite bedrock that releases radon gas as uranium decays. The Vermont Department of Health estimates that nearly one in three homes in Chittenden County has elevated radon levels above the EPA action level of 4.0 pCi/L. This makes Burlington a prime market for radon testing services. The city’s housing stock includes many older homes built before modern radon-resistant construction practices, as well as newer developments where buyers increasingly request testing during real estate transactions. Winter heating seasons trap radon indoors, creating peak demand from October through March. The market is moderately competitive with a handful of established firms, but many homeowners still test infrequently or not at all. Starting a radon testing business here offers strong potential if you can differentiate through quick turnaround, digital visibility, and trusted local recommendations.
Vermont does not currently mandate state-level certification for radon testers, but you must follow the Vermont Department of Health’s Radon Program guidelines. The most credible path is to obtain certification through the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB). Both require passing an exam and completing continuing education credits every two years. Without certification, you cannot legally provide testing for real estate transactions if the client relies on your results for a mortgage or disclosure.
You must register your business with the Vermont Secretary of State. Burlington city requires a General Business License from the City Clerk’s Office. Additionally, you need a Sales and Use Tax account from the Vermont Department of Taxes because you will be selling a service subject to the state’s 6% sales tax on testing fees (radon testing is taxable in Vermont). Check with the City of Burlington’s Codes and Permits Department to see if you need a home occupation permit if you operate from a residence.
Carry professional liability insurance (errors and omissions) and general liability coverage. Many real estate agents and home inspectors will only refer testers who can show proof of insurance. Vermont also has a limited radon disclosure requirement: sellers must disclose known radon levels and testing history. Ensure your test reports include disclaimers about measurement uncertainty to limit liability.
While the EPA does not license individuals, following the EPA’s Radon Measurement Protocol is essential. Use only NRPP‑listed continuous radon monitors (CRMs) or charcoal canisters with lab analysis. Keep clear records of all tests, including device calibration certificates, for at least three years.
