"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."

"James (company owner & inspector) provides an excellent service ($430). He is knowledgeable (18 years experience), punctual, had a quick turnaround time (37 page report available next day), and provided a wealth of information to explain findings. He also provides a Radon test (not purchased) and a Sewer Scope test (using sonar imaging, $125) separately upon request. I was equally pleased when James provided a home inspection (2014) on another Vancouver home I own."

"My crawl space was flooded due to a hot water leak, major moisture damage and unfortunately I did not know about Willamette restoration and used another company to dry out crawl space but walls in laundry room and entry had to be tore down and that's when Willamette Restoration came into picture and saved the day. They completed the finish work walls, flooring, countertop, painting, replacing cabinets and I cannot say enough about their professionalism, timely manner in getting the job done. They went above and beyond my expectations and their cost was far less than a quote by another company. If you want excellent workmanship Willamette Restoration should be your company of choice."

FAQs for radon gas testing projects in West Linn, OR

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
