"They did a great job.  It took two tries but they were able to remove enough soil to pass DEQ's test.  They filled the hole and left the property clean.  They came in within their estimate. <br />"

"Oregon Restoration devised a plan to remediate the light mold in our attic.  Do your homework.  Mold is caused by something and you need to fix the cause not just remediate the problem.  Ryan referred me to Balanced Energy Solutions who corrected the inadequate air flow and improper venting which created the mold growing environment.  i.e. poor soffit ventilation, inadequate roof ventilation, and improperly vented bathroom fans.  Once this was done Ryan returned and created a negative air flow environment in he attic with a HEPA exhaust to the outside while working.  This scrubbed the air of the chemicals and any mold that was released.  His work was quick, neat, and efficient.  I inspected the attic later in the day and it looked great.  He guarantees a passing mold inspection post work and gives 3 subsequent annual inspections. <br /> They do not do mold inspection but remediation.  I would advise not to use one company for both as there is a conflict of interest as they would be creating their own work.  Just get a bid from someone that does this and you will see.  I experienced this while getting my bids and it is worth getting several bids from mold inspectors, and mold removal companies but definitely not someone who does both.  An inspector can test the mold for a fee to tell you what type it is but it doesn't really matter.  It's mold and you have a problem that needs correction.  Save your money and fix the problem and the mold.  I'm so pleased I contacted them and followed their advice to get an independent inspection, have the air flow corrected, and finally remediate the mold.  Also if you are able to follow the inspectors into every nook and cranny of the area you need work done.  The more knowledge you have the better of a job you will get done. <br />"

"The whole process from testing, system design and installation went better than I ever expected. Everyone at this company was professional, competent and friendly. They answered all my questions, the installation went great and they were able to reduce my radon levels to barely detectable levels. I would recommend this company to anyone needing radon mitigation."

"Roland arrived promptly to the condo and had started before I even got there. He was prompt, thorough and professional in his inspection and communication. The inspection was at 9 AM on a Thursday morning and I got his full report with pictures via email by 10 that night. Roland also sent over the Radon report sunday evening (takes 2-3 days to collect the data)."

"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

"This was a very thorough inspection with a lot of detail.  We have put our home on the market and wanted to address significant issues prior to negotiations.  This provided us with the list of items to address. We gave it to our contractor who then made the repairs.  We now have certification of the inspection and the repair work. <br />"

"I hired Environmental Works on the recommendation of a co-worker. Not only was it the least expensive of the three bids I received but it was also the only company that offered a lifetime guarantee on its work. The entire installation of a radon mitigation system in my home took less than six hours. The company guarantees that its radon mitigation system can keep radon levels below 2.7 pCi/L. A three-month radon monitoring test, completed ten months after the installation of my mitigation system, indicated radon levels at 1.4 pCi/L. I am very pleased with the work that was performed at my home."

FAQs for radon gas testing projects in Salem, 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.
