Des Moines, Iowa, sits in an area with some of the highest radon levels in the United States. The Iowa Department of Public Health estimates that nearly 70% of Iowa homes have radon levels above the EPA action level of 4.0 pCi/L. In the Des Moines metropolitan area — including suburbs like West Des Moines, Ankeny, Urbandale, Clive, and Altoona — the combination of clay and loam soils, plus cold winters that keep homes sealed tight, creates an ideal environment for radon accumulation. Homebuyers are increasingly aware of the health risk, and real estate transactions commonly require a radon test before closing. This creates a steady, year-round demand for professional radon testers. The market is moderately competitive, with a mix of independent specialists and larger mitigation companies that also offer testing. A focused testing-only business can carve out a niche by offering faster turnaround, better reporting, and localized expertise.
As of 2025, Iowa does not require a specific state license to perform radon testing. However, the Iowa Department of Public Health (IDPH) strongly recommends that testers become certified through a national program. Two widely recognized certifications are the National Radon Proficiency Program (NRPP) and the National Radon Safety Board (NRSB). Many real estate agents and home inspectors in Des Moines will only work with NRPP or NRSB certified testers. Certification involves passing an exam (online or in-person), completing continuing education every two years, and adhering to a code of ethics. The cost is roughly $200–$300 for the initial exam and application, plus annual renewal fees.
You must register your business with the Iowa Secretary of State (https://sos.iowa.gov) and obtain a local city business license if you operate within Des Moines city limits. The City of Des Moines requires a "General Business License" for any home-based service business; the fee is approximately $50–$100 per year. You will also need a Federal EIN from the IRS if you plan to hire employees or operate as an LLC. Liability insurance is strongly recommended — most Des Moines real estate offices will require you to carry at least $1 million in general liability coverage. Radon-specific errors and omissions (E&O) insurance is also wise and costs around $500–$800 per year.
Even without a state license, the EPA’s “Protocol for Conducting Measurements of Radon and Radon Decay Products in Homes” outlines the accepted methods. In Des Moines, the most common approach is using continuous radon monitors (CRMs) for a 48-hour test. You must follow placement guidelines: test in the lowest livable level, avoid bathrooms and kitchens, set up away from drafts, and keep windows and doors closed during the test. Violating these protocols can lead to claims of fraud in a real estate transaction.
