Connecticut Department of Public Health (nationally certified lists)
Connecticut radon professionals
92 people compiled from official CT DPH PDFs. 55 measurement only, 16 mitigation only, 21 both. Source lists dated 3-31-2025 (updated April 4, 2025). Retrieved 2026-09-07 (US/Pacific).
If you are not sure you need a pro yet, see when a DIY radon test kit is enough or how to test a home for radon.
Connecticut does not issue a state radon license. CT DPH maintains these lists under Conn. Gen. Stat. § 19a-14b of companies or individuals on approved national radon proficiency programs (NRPP or NRSB). Names, companies, cities, and phones are transcribed from the official PDFs — nothing invented. Mitigation listings also note CT Department of Consumer Protection home-improvement contractor (HIC) registration where printed. Asterisked measurement names are marked as analytical measurement providers on the CT DPH list. Some firms are based outside Connecticut and still appear on the DPH lists. Company spellings follow the PDF (including odd wraps such as LplLC).
Always verify the credential is still current with CT DPH, NRPP, or NRSB (and CT DCP e-License for HIC numbers) before hiring. This index does not rank contractors or take referral fees.
