"I hired Marty to perform a home inspection on a home I was interested in buying. I was so impressed by his work so I hired him again for another home. His work is superb. He takes his time and really analyzes every square inch of the home. He answered all of my questions thoroughly and also explained anything he found with great detail. His prices are cheaper than anyone else and his work is expensively performed. He is a true professional and I would highly recommend him to anyone."

"Overall, I'm satisfied with a passing grade. Initial appointment and set-up (with Jenn) for the service were above average(4/5). The mitigation test was done correctly and promptly. Setting the appointment for the installation was easy. The overall installation was satisfactory. However, it was below my expectations as (1) a dedicated separate electric outlet should have been used instead of an existing one I used in the garage for my mosquito control unit. If required, an additional outlet is included in the estimate for the work provided. (2) the fan's wire should have been appropriately put, as any loose wires (which we had) might have been caught in the garage tracks. Below the grades given for James Soos (the guy with the cowboy hat), I would give him a below grade for his interaction with customers (not friendly acts like these jobs are below his grades). He also messed up our porch and carpets with his dirty shoes. My expectation for people who come inside our house is to have shoe protection. I would give him a failing grade (2/5). Otherwise, the installation was okay, and the tech who installed the fan and the pipes was excellent (4/5). Additional electric work James Soos (the cowboy hat guy) did was above average (4/5), though not personable (2.5/5). Post mitigation testing was done properly and was easy."

"I had got my House Inspected from Mark on Aug 2022. everything went fine until I moved into the house. Couple of months after move-in I found old dried water marks in storage and HVAC room in my basement. I was hoping that these water marks were owing to old water heater leaks but then in early 2023 there was heavy rainfall and the HVAC room basement started leaking water into the room. It was then I found that there was a crack in the basement wall. This crack is next the furnace duck and quite easily visible. Mark suggested that he is a season home inspector but I doubt because he missed visible evidence of prior basement flooding and a basement crack that was easily visible. I contacted Mark and send him proofs of his grave mishaps. He asked for proofs whether i have applied the suggested fix per inspection report, to which I promptly responded and then he stopped responding on my emails. He is not the person to get you house inspected"

FAQs for radon gas testing projects in Mendham, 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.
