"The home inspections performed by Bill were professional, descriptive and comprehensive. I hired Bill to perform two home inspections and I was extremely delighted with his knowledge and expertise of the various components within the inspection process. He provided his professional and honest opinion based on his knowledge and experience, which assisted with decisions in the home purchase process. We appreciated his thorough services."

"As a first time home buyer at the age of 26, I was not sure what to expect with the inspection. Scott was a pleasure to work with from the start. He was very professional from our first phone call. He made it very clear how the process would work on the day of inspection and outlined all costs before we even scheduled with him. This professionalism continued into the day of the inspection. He was early to the house. He was very thorough as he inspected every inch of the outside and inside of the house, top to bottom. He allowed us to walk along with him and effectively answered any questions we had. He got our report back to us the next night after the inspection because he knew we were on a tight timeline with closing. Everything he mentioned to us as we walked through the house was on the inspection report with pictures included. He even answered promptly when I had additional questions after we heard back from the selling side about our repair request. I highly recommend using Scott for your home inspection. I will be using him again when I move next."

"<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 />"

"It went so good! We had Brian come out and he did a fantastic job! He showed up early and did the whole outside and when we got there he walked us around and showed us all the things he had taken picture of. He took us through each room explaining each thing and telling us what was very important to fix right away. He was very friendly and listened to any and all concerns we had during the inspection. Also the write up they do about all of their finding is wonderful! They include picture and detailed descriptions of each thing so you don't have to question what was wrong. They add arrows and circles to the photos also so you don't have to guess where the problem is. I was very happy with this service and would recommend them to anyone!"

"I can't say enough about how professional they are.  I met the regional manager at the property and he explained what we were looking for and how he would test for radon. He also explained how their system worked and how it might be implemented if there was a problem. The test results are evaluated by a 3rd party testing company so I knew the results would be accurate and wouldn't be influenced by SWAT Environmental.. <br /> The tests came back positive with fairly high levels of radon (over 80 PiC/L).  James came out a second time and explained how they would install the system and retest, guaranteeing that they would get the radon down below 4 PiC/L  They scheduled the installation within a week.  The installation technician, Sean, was unbelievable.  He was neat, courteous and did a fantastic job with the installation. All holes were clean and neat, the exterior work was excellent and they even took the pipe up through the overhang to the roof - minimizing the visual impact of the system on the home.  The pipe and fan system were painted to match the gutters and really fit in with the rest of the house. <br /> The system brought radon levels down to 30 PiC/L but not enough to resolve the issue.  The house is unusual construction - it's on a two level slab and the floors and ceilings are beam and plank construction - no joist cavities.  The house was originally built and owned by an architect so the construction is unique and unlike any other house we've seen. I'm not surprised we had problems getting the radon levels down on the first try.  The amazing thing is they came back and installed a second system AT NO ADDITIONAL COST.  Their guarantee is more than just giving your money back - they continued to work on the two systems until radon level met EPA standards.  <br /> That's how amazing this company is.  There was never a suggestion of them pulling out or making excuses.  I can't say enough about how professional this company is.  I work in the construction industry and never have I run into a company that is as committed to resolving problems and great customer service as this one. If I could hire these guys to do my construction work my life would be so much easier and I'd hire them tomorrow if Sean or James wanted to jump ship. <br />"

FAQs for radon gas testing projects in Audubon, NJ

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.
