Why radon testing matters in Hopkins
Older basements with stone or block foundations, sump pits, and unsealed floor cracks are nearly purpose-built for radon entry — testing is essential rather than optional in homes of this era.
Hopkins is served by Hopkins Public Schools and sits in Hennepin County, classified by the EPA as Zone 1 — the highest radon-risk category. Combined with older urban-adjacent clay with creek-proximity moisture considerations near Minnehaha, the inspection considerations specific to Hopkins are real and worth pricing in.
