"I had a great experience with Joe , getting a co-op unit inspected. His price was very reasonable and he was very accommodating when unexpected obstacles occurred on the day of the inspection. He was very thorough and knowledgeable. I love that he explained everything at the inspection, which was very helpful. Everything was also written out in a detailed report that he sent very promptly. We ended up not purchasing the unit. What really helped us with this difficult decision is Joe's leveled and unbiased relaying of what he found at the inspection. He didn't exaggerate any flaws for example. At the end of the day we feel like we dodged a bullet after the inspection and will definitely be hiring Joe again once we find a home to purchase. Highly recommend him."

"My apartment is on the top floor of the building. The fire department broke through the roof, and they filled my apartment with water to put out the fire. They also broke a few walls. The insurance company sent in a fire restoration company to remove my damaged property and the damaged wall, ceiling, and floor materials. However, they were also supposed to clean the remaining walls, floors, and ceilings throughout the apartment that were not damaged/removed.

The building is old, so there is lead paint on most of the walls. As it turns out, the roof membrane contains asbestos, and some of the walls are constructed of cement. The laboratory test results of the samples collected in my apartment indicated that my apartment was contaminated with asbestos from the roof, lead dust from the paint, silica from the cement walls, and mold from water damaged sheetrock surfaces that were not removed. Residual carbon soot was also found on the windowsills in my bedroom.

The Angstrom Mold Inspection Report was very well written, and it included a detailed scope of work for the necessary additional removal and cleaning work that was needed in my apartment. The lab reports documented the presence of contaminants, which substantiated the need for additional work. I gave the Inspection report to my insurance company, and they had the restoration company return to my apartment to perform the necessary additional removal and cleaning work. Then I had the Angstrom Mold Inspection Company return to perform a follow-up inspection and testing, and the lab results came back negative. Thank God!

This company is great, and I fully trust their expertise. Well worth the money."
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."

"John M. was courteous, timely, and professional in his inspection. He was upfront about the issues -- whether they are serious or minor, rare or common, and whether more specialized input is required. His written report was very well done and will serve as a great home guide for us in the future after we move in. Thank you!"

FAQs for radon gas testing projects in Williamsbridge, 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.
