Radon Mitigation in Bloomington, Minnesota
Bloomington is Minnesota's signature rambler city, block after block of 1950s and 1960s single-story homes over full basements, and it sits in Hennepin County, rated Zone 1 on the EPA Map of Radon Zones. The Minnesota Department of Health reports 2 in 5 tested homes statewide at levels posing a significant health risk, and mid-century basements, where Bloomington families put their rec rooms and spare bedrooms, are exactly the space that matters.
We connect Bloomington homeowners with independent, MDH-licensed mitigation contractors for free written quotes, from East Bloomington ramblers to walkouts above the Minnesota River bluffs.

Radon Levels Around Bloomington
Zone 1
the EPA radon zone for Hennepin County, predicting average indoor levels above 4 pCi/L
Zone 1 is the highest of the EPA's three radon potential categories, and MDH's statewide numbers give Bloomington no exemption: 2 in 5 tested homes high, an average more than three times the national average. County-level test results are published on the MDH data portal, and finished mid-century basements make the stakes practical rather than abstract.
Till Plains and River Bluff Terraces
Bloomington spreads across glacial till plains that drop to terraces and bluffs above the Minnesota River valley, all of it part of the glacial cover the Minnesota Geological Survey maps across the metro. MDH attributes radon to uranium decaying naturally in rocks and soil, and glacial till is the classic Minnesota carrier. On the bluff edge, walkout construction changes how homes meet that soil, which shows up in mitigation design more than in the geology itself.

The core stock is the postwar rambler and split-level on a concrete-block basement, frequently finished into living space decades ago. Those homes are clean single-suction-point candidates, with routing chosen to keep the system discreet. Along the river bluffs, walkouts may need a second suction point to cover the slab. Newer infill and anything permitted after June 1, 2009 carries the passive rough-in required by Minnesota Rules 1303.2400, which a licensed contractor can activate with a fan if a test runs high.
Local Radon Contacts and Test Kits
Bloomington is one of the few Minnesota cities with its own public health division, and metro residents can find every current radon kit program and contact in the MDH Local Radon Contacts directory.
What Does Radon Mitigation Cost in Bloomington?
The Minnesota Department of Health reports a typical installed range of $1,500 to $3,000 statewide. Foundation type, home size, and routing decide where a Bloomington home lands. The cost guide breaks down every factor with primary-source numbers.
Verify Your Contractor's Minnesota Radon License
Before you hire anyone for radon work in Bloomington, check their license. The Minnesota Radon Licensing Act, Minnesota Statutes section 144.4961, requires anyone who performs radon testing, mitigation, or laboratory analysis for compensation to be licensed by the Minnesota Department of Health, and every mitigation system installed under the law must carry an MDH system tag. A licensed professional expects the question. Three things to ask before you sign:
- Can I see your current MDH radon license, and is the company licensed too?
- Will the installed system carry the MDH system tag required under the licensing law?
- Will I get a written, itemized estimate and a follow-up radon test that confirms the system works?
Bloomington Radon Questions
Are Bloomington ramblers prone to high radon?
They sit in EPA Zone 1 Hennepin County on classic glacial till, and their full basements are usually finished living space, which raises the exposure question MDH cares about. The construction era itself is not the risk; the soil under it is. A test settles it for your address.
Will a radon system ruin the look of my finished Bloomington basement?
Installs in finished basements are routine. Contractors typically core the suction point in a utility area or closet and route the pipe through the garage or a chase to the exterior, keeping finished spaces untouched. The manometer ends up somewhere you can check it, not somewhere you have to look at it.
My Bloomington walkout backs the river bluff. Does that change mitigation?
Sometimes. A walkout wall open to grade changes how suction spreads beneath the slab, and bluff-edge homes occasionally need a second suction point for full coverage. Licensed contractors design for it at quote time and prove coverage with the follow-up test.
What does radon mitigation cost in Bloomington?
The Minnesota Department of Health reports a typical installed range of $1,500 to $3,000 statewide, and the EPA cites a national average near $1,200. Finished basements and discreet routing are the common Bloomington variables. Your written quote is free and specific to the house.
