Active Radon Management LLC services western North Dakota.

We offer free in person, over the phone or FaceTime bids within 25 miles of Bismarck/Mandan. Outside of this area, we offer free bids over the phone or FaceTime.

When traveling out of town, we like to keep costs low. If you live outside of the Mandan/Bismarck area and want a mitigation system from us, talk to the neighbors as well! The more people we can service in one trip, the lower our traveling prices are for everyone included.

We love seeing all of the small towns dotted across the state, and we strive to make mitigation available to everyone regardless of where you may live.
