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 (3) ✔ MPCA SSTS licensed Inspector ### Zierke Soil Testing, LLC 28587 Jeffrey Ave, Chisago City, MN 55013 ☎ [(651) 249-1346](tel:6512491346) ✉ benzierke@gmail.com Certified staff: Benjamin J Zierke Also licensed: Designer License L119, expires 2028-04-14 · bonded, insured Source: [MPCA SSTS](https://services.pca.state.mn.us/api/doc/v1/ssts/licensed-businesses), retrieved 2026-10-12 · [Claim/correct/remove](https://mnhomesalepros.com/list-your-business/?id=SL119) ✔ MPCA SSTS licensed InspectorIntermediate InspectorAdvanced Inspector ### AT Septic Inspection & Design Inc 49861 Government Rd, Rush City, MN 55069 ☎ [(320) 980-0235](tel:3209800235) ✉ atsepticinspections@gmail.com Certified staff: Amy J Thompson Also licensed: Designer, Installer, Maintainer, Service provider, Pipelayer License L3886, expires 2027-08-12 · bonded, insured Source: [MPCA SSTS](https://services.pca.state.mn.us/api/doc/v1/ssts/licensed-businesses), retrieved 2026-10-12 · [Claim/correct/remove](https://mnhomesalepros.com/list-your-business/?id=SL3886) ✔ MPCA SSTS licensed InspectorIntermediate InspectorAdvanced Inspector ### Thompsons Sewer Service & Soil Testing Inc 49861 Government Rd, Rush City, MN 55069 ☎ [(320) 358-9941](tel:3203589941) ✉ pcthompson2010@hotmail.com Certified staff: Amy J Thompson, Cindy L Thompson, Gerald P Thompson, Phillip E Thompson Also licensed: Designer, Maintainer, Service provider License L261, expires 2027-03-20 · bonded, insured Source: [MPCA SSTS](https://services.pca.state.mn.us/api/doc/v1/ssts/licensed-businesses), retrieved 2026-10-12 · [Claim/correct/remove](https://mnhomesalepros.com/list-your-business/?id=SL261) ## Radon testing and mitigation (2) ✔ MDH radon license MeasurementMitigation ### Solution Enhance LLC 2816 183rd Ave NE, East Bethel, MN 55092 ☎ [(651) 424-3075](tel:6514243075) 🌐 [solutionenhance.com](https://solutionenhance.com/) 2 MDH-licensed professionals * Ngao Vang (RMEA-00616) * Yia Xiong (RMITS-00053) 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=M234) ✔ MDH radon license MeasurementMitigation ### Hss 3140 Viking Blvd NE, Wyoming, MN 55092 ☎ [(763) 434-3263](tel:7634343263) 🌐 [homesafetysolutionsinc.com](https://www.homesafetysolutionsinc.com/) 2 MDH-licensed professionals * Henry Donnay (RMIT-00134) * Walt Donnay (RMIT-00027) 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=M114) Data last verified 2026-10-12 against MPCA's SSTS licensed-business data and MDH's radon service provider list. ## Neighboring counties [Anoka County](https://mnhomesalepros.com/county/anoka/) · [Isanti County](https://mnhomesalepros.com/county/isanti/) · [Kanabec County](https://mnhomesalepros.com/county/kanabec/) · [Pine County](https://mnhomesalepros.com/county/pine/) · [Washington County](https://mnhomesalepros.com/county/washington/) ## 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/)
