Finding a qualified radon professional near River Falls

Check national certification

Wisconsin DHS recommends hiring someone certified by one of two EPA-recognized programs:

1. NRPP: search at nrpp.info
2. NRSB: search at nrsb.org

Pick “measurement” for testing or “mitigation” for installing a system, then enter your ZIP code. Some people hold one certification and not the other, so filter for the job you need. DHS says nearly 150 contractors across Wisconsin hold one of these credentials.

If the company is from Minnesota

Many Twin Cities–area radon companies also hold a Minnesota license, which the Minnesota Department of Health issues and renews every year. That’s a solid sign. It doesn’t replace asking about NRPP or NRSB certification for a Wisconsin job, but a company that meets both is a good place to start. Our Wisconsin vs. Minnesota rules page explains the difference.

Your local Radon Information Center

Pierce and St. Croix counties are served by the Northwest Central Wisconsin Radon Information Center at the Dunn County Health Department. Staff can explain a test result and point you to low-cost kits. Current contact details are on the DHS Radon Information Center page.

Questions worth asking every contractor

• Who on the crew holds the certification, and what’s the number?
• Do you check sub-slab airflow before choosing a suction point?
• Where do the fan and pipe go, and where does it discharge?
• How do you handle frost and condensation in the pipe?
• What sealing is included?
• Is a post-mitigation test included?
• What does the written warranty cover?

Wisconsin DHS recommends getting estimates from at least three companies. Put the answers side by side before you choose.
