"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.

"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."

Radon Detection and Reduction questions, answered by experts

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.
