The Northwest's most experienced firm. Residential and commercial radon testing, mitigation, and system design for homes, schools, businesses. Radon-resistant design for new homes.

Radon Detection and Reduction questions, answered by experts

Mitigation reduces radon levels, protecting your health and complying with safety standards.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Testing typically costs between $150 and $500, depending on the method used and the number of areas tested.

Results from radon testing usually take a week to process after the test period ends, with expedited services sometimes available for urgent cases.

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.
