"When my son tested positive for lead I was obviously very anxious to get my home tested. I reached out to my local Department of Health for guidance and they told me to make sure that whomever does the testing be EPA certified and use XRF, which is why I chose Lead and Mold Detectives. They got back to my request for an estimate in record time and made an appointment for me for the following week. Tested the entire house using XRF and kept me in the loop throughout the process. Very happy with their work and would use them again in the future."

Quendrim's advice and assistance helped us tremendously into making sure we have a safe environment for us and our kids. Report was easy to read and understand and the lead abatement people were able to go off that report to fix everything. Thank you!!!"

"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.

Lead Testing and Removal FAQs, answered by experts

Lead exposure poses serious health risks, particularly for children, and can be present in paint, pipes, and soil.

When a surface that contains lead dust is disturbed, the dust can float about in the air for roughly an hour before settling again. Since you cannot see the dust, it is important always to wear protective gear when working with any materials that may contain lead paint and to keep children, pets, and others away from the area for as long as possible

Some causes of brown well water—like excess tannins or dissolved iron—don’t pose a health risk. In other cases, harmful bacteria might be the culprit. If your well water has suddenly turned brown, it’s a good idea to use a home water test kit to get a better sense of what’s going on with your water. Consider calling a professional for an expert opinion before drinking the water and hoping for the best.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

Unfortunately, lead dust does not look different from any other type of dust. You cannot detect it with the naked eye. To determine if you have lead dust in your home, you will need to hire a local company to take a sample from the paint and test it for you in a lab.
