"I can't recommend REI highly enough. I called and Frank got my inspection scheduled ASAP and well within my time frame. Pete did a very thorough inspection of the home, checking every system and detail, and answering every question I had. He then provided me with a detailed report within 48 hours, well organized, and included estimate ranges for repairs. If I purchase the property, Pete's report will become a dog-eared reference for years to come. The cost was reasonable for having three inspections (house, termite, radon) of a large, old home. Thank you Pete, Frank, and REI!"

"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."

"Scott from Landmark Inspections performed a home inspection of the home my husband and I are purchasing. We are first time home buyers and this is our first home inspection. We were very impressed with Scott from beginning to end. Before the inspection, he was responsive and communcative, answering every one of our phone calls and emails. The inspection was thorough and Scott and his trainee inspector (also Scott) took the time to answer our questions and explain everything they were doing/finding. The inspection did not feel rushed or like Scott was trying to get through it to move on to the next. The report he sent us (48 hours after the inspection, great turn around time) was very throrough, contained useful information about our future home, and clearly laid out a heirarchy for recommended repairs. We also got a termite inspection, sewer scope inspection (which was also performed incredibly professionally by Melvin from Knox & Knox Solutions), and raydon test. In total, we paid a lot of money for these services, but it was money very well spent. We would not hesitate to recommend Scott, Landmark, and the other service professionals with whom he contracts."

"<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 />"

"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 />"

"I am a first time home buyer and had been told about Ross through my realtor. I called to just shop around on prices and he gave me tons of information that helped me decide he was the one. “Medium pricing” for excellent work is how I put it. He responded to all my messages promptly, huge bonus since I am out of state! I got to watch all videos of the inspection and he mentioned how to keep up with things and the maintenance on things. I got lucky with a good home but also a great home inspector. We couldn’t do a roof inspection but he flew a drone up there to look at it, how cool! Definitely recommend Ross and will totally go through him in the future if need be. Thank you!!"

FAQs for radon gas testing projects in Lawnside, 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.
