Radon mitigation quotes in Bloomington, Minnesota
Bloomington is the Twin Cities’ largest first-ring suburb, built out substantially in the postwar decades with ramblers and split-levels, plus newer development along the I-494 corridor.
Postwar housing brings predictable, competitive quotes. Bloomington homeowners hire independent, MDH-licensed contractors for free.
Bloomington and Hennepin County
Bloomington routes through our Hennepin County territory alongside Minneapolis, Minnetonka, St. Louis Park, and Hopkins. EPA places Hennepin County in Zone 1 on its Map of Radon Zones. Minnesota licenses radon measurement and mitigation professionals through the Department of Health.
If the result surfaced in a transaction
Bloomington turns over steadily at family price points, and radon testing is routine in Twin Cities inspections. Minnesota sellers disclose known radon information and provide the MDH publication before a purchase agreement is signed; the remedy is negotiated between the parties.
Those duties are set in Minnesota, not in Hennepin County — Minnesota radon disclosure rules has the statute and the agency behind it, including what a seller must hand over and what stays negotiable.
The housing you’re mitigating
Expect postwar ramblers and split-levels on block or poured foundations, most with full basements and many with sump systems where drain tile makes a sealed-pit design efficient. Split-levels deserve zone-by-zone quotes naming every foundation section. Newer corridor construction is conventional poured work.
Radon results do not stop at a municipal boundary, and neither do the contractors quoting here: the same Hennepin County soil and the same building era run through Minneapolis, Eagan and Maple Grove, which is why a reading in one of them is worth knowing about when you are interpreting yours. For the wider picture, radon across Minneapolis–St. Paul sets out how results vary between communities here, and what a system costs in Minneapolis–St. Paul covers the price drivers before you start collecting numbers.

Bloomington questions, answered straight
We have a split-level. How does a system get designed around that?
By treating the house as its zones — basement slab, any slab-on-grade section, and any crawl area, commonly all on one fan. The failure mode to watch for is a quote that silently skips a zone.
What is a sealed sump-pit system?
It uses drain tile you already have. Sealing the pit with an airtight lid and drawing suction from it can depressurize the whole perimeter tile network beneath the foundation, often without coring the slab. Your pump keeps operating under the lid.
How much does mitigation cost in the Twin Cities?
Straightforward basement installs are commonly quoted in the low four figures, with multi-zone foundations, finished-basement routing, and historic masonry quoting higher. We publish a full cost breakdown rather than promising your number.
Which doors, windows, and fans have to stay shut for the measurement?
Keep windows and outside doors closed except when someone walks through, starting 12 hours before the device goes live and continuing until it comes out. Whole-house fans and window units stay off; the furnace and central air run normally. In a Bloomington spring or autumn, an open window is the most common way a test gets invalidated — and inside a purchase contract, a compromised measurement is one the other side can reasonably refuse to accept.
We are buying a house that already has a system. Do we still test?
Yes, inside the inspection period if the calendar allows. The presence of hardware tells you something was done at some point. It says nothing about whether it is doing anything now. Failures here are quiet: motors stop without warning, gauges get disturbed, and renovation crews cut into risers. Confirm the manometer columns are offset, listen for the fan, ask for the original post-mitigation report and the installer's MDH license, then run your own short-term test and negotiate from a current number.
