--- title: "Septic Inspectors & Radon Pros in St. Louis County, MN: 6 Licensed | MN Home Sale Pros" description: "0 MPCA-licensed SSTS inspectors and 6 MDH-licensed radon pros based in St. Louis County, Minnesota, for home sales." canonical: https://mnhomesalepros.com/county/st-louis/ --- [Home](https://mnhomesalepros.com/) › [Counties](https://mnhomesalepros.com/counties/) › St. Louis County # Septic inspectors and radon pros in St. Louis County, MN 0 MPCA-licensed SSTS inspector businesses and 6 MDH-licensed radon businesses list an address in St. Louis County. Many work across counties, and most radon pros list a statewide service area. Minnesota has no single statewide septic-at-sale rule, but many counties and cities require an SSTS compliance inspection at property transfer by local ordinance ([MPCA local SSTS programs](https://www.pca.state.mn.us/business-with-us/local-septic-system-programs)). Ask the county or city SSTS office whether a transfer inspection applies. Inspections must be done by an MPCA-licensed SSTS inspector business. ## SSTS (septic) inspectors None list a St. Louis County address. Use the [statewide list](https://mnhomesalepros.com/septic-inspectors/) or the [MPCA search](https://webapp.pca.state.mn.us/ssts/business-search), which can filter by service county. ## Radon testing and mitigation (6) ✔ MDH radon license Mitigation ### Adamski Builders LLC 239 E Myrtle St, Duluth, MN 55811 ☎ [(218) 727-2495](tel:2187272495) 🌐 [radonab.com](https://radonab.com) 1 MDH-licensed professional * Jamie Adamski (RMITS-00010) Service area (per MDH): Statewide Source: [MDH Radon Service Providers](https://radon.web.health.state.mn.us/serviceProviders.jsf), retrieved 2026-10-12 · [Claim/correct/remove](https://mnhomesalepros.com/list-your-business/?id=M009) ✔ MDH radon license Measurement ### Bluewater Professional Inspections 5220 Otsego St, Duluth, MN 55804 ☎ [(218) 343-5631](tel:2183435631) 1 MDH-licensed professional * Dana Dargontina (RMEA-00430) Service area (per MDH): Statewide Source: [MDH Radon Service Providers](https://radon.web.health.state.mn.us/serviceProviders.jsf), retrieved 2026-10-12 · [Claim/correct/remove](https://mnhomesalepros.com/list-your-business/?id=M040) ✔ MDH radon license Measurement ### Van Dyke Home Inspections LLC 2003 Minnesota Ave, Duluth, MN 55802 ☎ [(218) 391-0356](tel:2183910356) 1 MDH-licensed professional * Kenneth Van Dyke (RMEA-00033) Service area (per MDH): 100 miles Source: [MDH Radon Service Providers](https://radon.web.health.state.mn.us/serviceProviders.jsf), retrieved 2026-10-12 · [Claim/correct/remove](https://mnhomesalepros.com/list-your-business/?id=M254) ✔ MDH radon license MeasurementMitigation ### Glenn’s Fix It LLC 422 Highland Dr, Box 165, Hibbing, MN 55746 ☎ [(218) 969-5543](tel:2189695543) 1 MDH-licensed professional * Glenn Muster (RMITS-00020) Service area (per MDH): Statewide Source: [MDH Radon Service Providers](https://radon.web.health.state.mn.us/serviceProviders.jsf), retrieved 2026-10-12 · [Claim/correct/remove](https://mnhomesalepros.com/list-your-business/?id=M085) ✔ MDH radon license Measurement ### Institute for Environmental Assessment 5525 Emerald Ave, Mountain Iron, MN 55768 ☎ [(763) 315-7900](tel:7633157900) 1 MDH-licensed professional * Amanda Harten (RMEA-00283) Service area (per MDH): Statewide Source: [MDH Radon Service Providers](https://radon.web.health.state.mn.us/serviceProviders.jsf), retrieved 2026-10-12 · [Claim/correct/remove](https://mnhomesalepros.com/list-your-business/?id=M128) ✔ MDH radon license MeasurementMitigation ### Advanced Radon Solutions 914 Bass Blvd, Proctor, MN 55810 ☎ [(218) 491-3752](tel:2184913752) 🌐 [advancedradonsolutions.net](https://www.advancedradonsolutions.net) 2 MDH-licensed professionals * John Ellestad (RMIT-00136) * Zackary Ellestad (RMIT-00139) Service area (per MDH): Statewide Source: [MDH Radon Service Providers](https://radon.web.health.state.mn.us/serviceProviders.jsf), retrieved 2026-10-12 · [Claim/correct/remove](https://mnhomesalepros.com/list-your-business/?id=M013) Data last verified 2026-10-12 against MPCA's SSTS licensed-business data and MDH's radon service provider list. ## Neighboring counties [Aitkin County](https://mnhomesalepros.com/county/aitkin/) · [Carlton County](https://mnhomesalepros.com/county/carlton/) · [Itasca County](https://mnhomesalepros.com/county/itasca/) · [Koochiching County](https://mnhomesalepros.com/county/koochiching/) · [Lake County](https://mnhomesalepros.com/county/lake/) ## Guides [Septic (SSTS) at sale](https://mnhomesalepros.com/septic-inspectors/) · [Radon at sale](https://mnhomesalepros.com/radon/) · [Truth-in-Sale of Housing](https://mnhomesalepros.com/truth-in-sale-of-housing/)
