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

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

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

Radon is a colorless, odorless gas that can cause lung cancer; testing ensures safe indoor air quality.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Yes, DIY kits are available, but professional testing provides more accurate results and comprehensive reports.
