We are a group of Certified Industrial Hygienists (CIHs), Qualified Environmental Professionals (QEPs), and Certified Indoor Environmental & Microbial Consultants (CIECs) that performed air quality testing in residential and commercial spaces, frequently in response to occupant health complaints, odor complaints, or for precautionary measures. We also conduct mold inspections, asbestos, inspections, XRF lead paint testing, chemical vapor testing, formaldehyde air testing, environmental mycotoxin testing, phase 2 assessments, and more.

Ground water infiltration occurred through the concrete slab in two rooms on the ground floor of the house causing water damage and mold growth on the overlying flooring. The cause of the water infiltration appears to be associated with cracks and a crater in the concrete slab, which is believed to have been caused by pile driving work being performed during the construction of an adjacent building.
Mold in HVAC Coil Compartment
Construction/demolition work in an apartment unavoidably released high levels of dust that migrated into adjacent apartments. Dust containment methods, such as negative air filtration and poly sheeting, should have been used to prevent dust migration into adjoining spaces. Settled dust samples were collected from a table & curtain rod in a nearby apt, which revealed the presence of substantially elevated levels of silica and asbestos in the dust. Asbestos and silica are known carcinogens.

"The owner of the company, Phil Tantella, spent time on the phone with me giving me lots of information beyond what his scope involved. He was so helpful and knowledgeable. Working with his company was a good experience from start to finish. The process takes time, and Phil stayed in touch, keeping me up-to-date so I could move forward with other planning."

"My wife and I are first time home buyers, and we are extremely happy we ended up using True View for our inspection. Evan Weiss was our inspector, and he was absolutely fantastic. He was over 20 minutes early and got us started ahead of time. He was unbelievably thorough, and for first time buyers, he made sure we understood every note that he made. He went out of his way to make sure we were good before moving on to other parts of the house. He also had great advice for general things to keep in mind for maintenance and other tips for first time home owners. If you're thinking about using True View, I suggest you pick up the phone and book them today. We're so happy that we did, and in particular, we're so happy Evan was our inspector."

FAQs for radon gas testing projects in Astoria, 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.
