Radon gas is a problem nationwide. However, research shows that residents of New Jersey, Philadelphia, and the rest of the northeast corridor are at a higher risk than average. If you have not had your home tested, now is the time to do so.

The only way to be sure your home is free from radon is to have the property tested by professionals. Certified Environmental uses sophisticated equipment to detect radon in the basement and living spaces of your home. Our company standards are much higher than both national and NJ DEP’s regulatory standards and our diagnostic testing and mitigation are the most accurate and rigorous in the industry.

Frequently Asked Questions

Radon is a colorless, odorless radioactive gas that seeps up from the earth. When inhaled, it gives off radioactive particles that can cause lung cancer. According to EPA studies radon is the leading cause of lung cancer among non smokers.

The soil. Radon is produced from the natural decay of uranium that is found in nearly all soils. Uranium breaks down to radium. As radium disintegrates it turns into radon. As a gas, radon moves up through the soil and into the air you breathe.

While radon is present everywhere, and there is no known safe level, your greatest exposure is where it can concentrate indoors. And where you spend most time at home. Your home can have radon whether it be old or new and with or without a basement.

The goal of a radon mitigation system is to reduce the indoor radon levels to below the EPA action level of 4 pCi/L. A quality radon reduction (mitigation) system is often able to reduce the annual average radon level to below 2 pCi/L.

Certified Environmental Contractors were recommended highly to remove an underground tank. The property happened to be my own . I have held a Real Estate license for 22 years in Monmouth /Ocean COUNTY!! I have to say I would not hesitate to recommend them. They were great! They got the job done in a stressful situation for me!!! 5 Stars !!

I had a very challenging radon situation. Certified Environmental came back multiple times until they solved it - they stood by their commitment. They are professionals all the way. (I had used a different company for my system first - BIG MISTAKE - dishonest, avoided my calls, no-shows for appointments - only after looking deep into their reviews did I see people as dissatisfied as I was.) I can't recommend Certified Environmental enough and will be recommending them to my clients going forward without hesitation!

I am a licensed NJ home inspector, Focal Point Home Inspections, located in northern NJ, and have been using Certified Environmental for radon testing using their charcoal canisters. They are very accommodating, getting my order out same day. Test results are usually the next day or 2 days later. Highly recommended.
