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. We have been EPA-certified for over 25 years. Award winning. Radon is not a secondary endeavor for us… it’s all we do.

"Excellent from beginning to end. Very professional outfit from initial visit, quote, scheduling, work, followup. Price was reasonable, work quality went above and beyond, and radon levels dropped well below even the contractual level."

Radon Detection and Reduction questions, answered by experts

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Yes, most services include testing the generator to ensure functionality. Confirm with your provider.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.
