"We would definitely recommend Nu-Life Resources for any mold or ventilation problems that you might have. The crew was great, arrived on time and when they were through we couldn’t even tell they had been here. They were also great about answering any questions I had about the job."

"Our home has a radon mitigation system. We asked Janet to take Radon measurements, review the existing system, and make recommendations. She took measurements for 48 hours and determined that our radon levels were actually very low and that no further remedial efforts were needed. The price was very fair and no attempt was made to sell us something that we don't need."

"Dan judged that they could meet their guarantee (of 2pCi/l) with a slab penetration in a far corner of the basement that caused almost no loss of use of any basement basement space. The installation by Austin and Dan was very neatly done both in the basement and on the outside of the house. The result was a reduction of radon level from 5.6 to 1.2."

"<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 />"

"After a home inspection I was told that I needed to <br /> remediate a ?black substance? aka mold from the roof of my attic crawl space. <br /> The black stain covered most of the plywood and some rafters. I was told it was <br /> probably due to poor ventilation. <br /> I had less than two months to remediate before closing. This <br /> was a first for me so knowing where to begin and who to call was the most <br /> difficult decision to make. Not many people talk about mold in their home so <br /> finding a contractor was going to be a challenge. <br /> I went right to Angieslist and started looking and I came <br /> across Enzyme Life Sciences. I read the many reviews and saw pictures from one <br /> customer who had the same issue I had. There were before and after pictures of <br /> the job performed. I thought if my roof sheathing could look like that I would be happy. <br /> So I called and talked to Mike Partlow who understood my problem and he talked <br /> me through three part process of cleaning the mold and removing the stain. Mike <br /> is out in Albany but has trained contractors throughout the NYS region so being <br /> in Buffalo was not an issue. I talked with a few other contractors and some <br /> were either booked for the next few months or were on vacation ? (during <br /> December). Ultimately, I decided to go with Enzymes Life Sciences and I?m so <br /> glad I did. Within a week, Mike sent out a gentleman named Scott who cleansed <br /> the mold from the attic. The attic looked clean as promised. Mike also gives a <br /> 5 year warranty that is transferrable to the new owners which was very <br /> advantageous when adding it to the amended home contract with the buyers. <br /> Mike also stuck with me after the job checking in with me to make <br /> sure the sale was going through with the cleansing completed. That's one other thing <br /> to look for when shopping for a contractor; Mike is there for you and stands behind his work. <br /> Finally, the house closed on schedule within a few days of the final inspection. <br /> I can?t say enough about Enzyme Life Sciences, if you need to get rid of any <br /> mold in your home Mike is your guy. <br />"

"We did not end up getting a home inspection, because the sellers backed out of our contract. But Ian helped us work through asbestos issues related to the home and the contract and was knowledgeable and offered incredible professional services. He was kind and very nice to work with."

"Greg was very personable and very thorough in his home inspection. He gave good advice on home maintenance, showed us how things worked and answered all of our questions in a way we could understand. He emailed us a report immediately upon completion of the inspection. I would recommend him and would not hesitate to use him again."

"I can't say enough positive things about Jay.  He meticulously went over every detail of the observable part of the house. We discussed many items in the appropriate context of the need for repair as opposed to cosmetics. At the conclusion of the process I felt not only informed about the house, but educated as to what are and aren't real issues, how to examine things and what to expect from "keep an eye on" items for the future. For items that are "real issues," I understand what they are and why they are so. For things that are not "real issues" I understand why that is so as well.  <br> <br>While not formally part of the inspection, and thus as courtesy, he offered his personal opinion on the ease/complexity of making future adjustments in the house that we may chose to address based on preference, which was extremely helpful. <br>Most importantly, the formal report was received within a few hours of completion of the inspection. <br> <br> <br> <br>"

FAQs for radon gas testing projects in Nassau, NY

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.
