"Angstrom Testing used a moisture meter and found that one of the kitchen walls and an area of the kitchen ceiling in my mom's apartment were wet. Then they took an air sample in the kitchen and sent the sample to the lab to determine the level of mold in the air. After that, they made a cut into the wet area of the kitchen ceiling and found a dripping water pipe. The top side of the ceiling was black with mold. They also took a piece of sheetrock out of the top of the wet kitchen wall and found more mold on the back of the wall (yuck!!).
They called me two days later with the air test results, and they told me that the level of mold in the air was very high. They also told me that there was probably a connection between my mom's symptoms and high levels of mold in the air. Makes sense. They also told me that that my mom should stay upstairs with me and my husband until we get rid of the moldy ceiling and wall in her apartment.
A few days after they called, Angstrom emailed me a report with all of the details of what they did and found. In the report, they wrote recommendations and procedures that a mold removal contractor should follow to safely remove the mold and dry and treat the wood wall frames and wood ceiling. Since the level of mold in the air was so high, they said in their report that the kitchen air should be cleaned with an air cleaner and that the kitchen appliances, cabinets, and floor should be wiped down to get rid of all the mold spores that were laying around.
I really appreciated all the work they did and all of the advice that they gave me to help me and my mom. My mom is now living upstairs with me and my husband, and she says that she is already starting to feel better. Although my husband is not too happy (LOL). Great company! Thanks.

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.

"We are moving into an older house with asbestos covering on the pipes. A representative from JBH came in for an estimate and gave us a very accurate idea of the overall cost. Something that we were not able to confirm at the time of the removal...we were told this was a family-owned business and that someone from the family would come in to do the removal. Neither of the men who showed up introduced themselves as part of the family... The men from JBH showed up on time (very polite guys), removed all the asbestos, and then brought us down to show the work they had done. We were supposed to bring in an independent contractor for air monitoring, but the people we reached out to never returned our calls (they'll get their OWN review on Angie's List). In all the craziness of our move, we forgot that we never actually booked an air monitering company. We called JBH the day of the scheduled removal to let them know about the situation and to see if we should reschedule - they ended up calling someone in on our behalf to do the monitering. Not the ideal scenario, but it was great that they did the extra legwork with practically no notice. We did have to call JBH ourselves to follow up on the air testing results, which was the one downside."

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.
