How to Choose a Radon Mitigation Company in Akron & Cleveland

Last reviewed Oct 29, 2026 · Sources linked in the text

If your radon test came back at or above 4 pCi/L, EPA recommends fixing your home (EPA). In Ohio, who you hire matters, because the state licenses this work. Here is how to compare companies, based on EPA's and Ohio's own guidance.

Step 1: Confirm the Ohio license

The Ohio Department of Health licenses radon mitigation contractors (license numbers start with RC), mitigation specialists (RS) and testers (RT) (ODH).
Look the company up on ODH's Radon Licensure map, linked from its "Hire a Professional" page (ODH). Where a company publishes its license, our radon mitigation listings show it, but always confirm with ODH.
If the same company tested your home and now wants to fix it, Ohio rules require the written contract to disclose that and explain the value of long-term testing and a second opinion (OAC 3701-69-05).

Step 2: Ask EPA's questions

EPA's Consumer's Guide to Radon Reduction suggests asking each contractor, among other things:

Can you explain what the work involves, how long it takes and exactly how the system will work?
Do you charge for diagnostic tests? (EPA notes many contractors give free estimates but may charge for diagnostics.)
Did you inspect the house and review the quality of my test results before quoting?

And to check that each proposal includes:

Proof of state certification or licensing, liability insurance and needed local licenses
A warning device that alerts you if the system stops working
Testing after installation to confirm the system works
Any guarantee to reduce radon to 4 pCi/L or below, and for how long

Step 3: Compare quotes on more than price

EPA says most homes can be fixed "for about the same cost as other common home repairs," depending on the home's size and design and the method needed (EPA). It also cautions that a less expensive system may cost more to operate and maintain.

Mitigation systems "start at $995"	Akron Radon Pros LLC (Akron)
"Most installations in Northeast Ohio fall between $1,800 and $3,500"	Crowley Inspections, LLC
National average about $1,200, with $800 to $1,500 common	National Radon Program Services (Kansas State University)

Each company's or program's own published figure, not a quote. Your price depends on your house.

Step 4: After installation

Retest. EPA recommends testing again after the system is installed, and retesting every two years (EPA Citizen's Guide).
Watch the warning device, usually a manometer. EPA notes fans "may last for five years or more" and manufacturer warranties "tend not to exceed five years" (EPA).
Expect a small increase in your electric bill; EPA says fan systems "will slightly increase your electric bill" (EPA).
