"When I called the mold company for my lab results. They gave me a person named Ricardo Echeverria, Senior Mold Analyst to call for the results. He verbally told me that the cause was something like a remodel, construction going on. There was a red flag for a VOC called Methylene Chloride--Banned outdated paint. I sent Ricardo and email asking if I can have a report of what he said in writing. I only received a contaminants list. I said, I am not a scientist and do not understand the lab results.I never received a response back from him. I called Jeremiah Bancroft a few times and asked for a written explanation of the causes. He could not supply me with a written explanation because it was a legal issue. I asked for his help. I need your help. Jeremiah said, go to your primary care for a doctors note. That was the last time I spoke to him on September 19, 2024"

"I needed to have a mold issue addressed in my condo which had developed due to a leak in the roof. I contacted Aerotek Environmental having received their contact details from Angi Ads. From my first contact with Brandon of Aerotek Environmental he was the most helpful of all that I had spoken to about my issue. In addition to giving a reasonable cost estimate, Brandon took the time to carefully explain the step by step remediation process that his company would provide which included digital photos before, during and on completion of work. Having decided to use Aerotech the process ran very smoothly from setting the schedule date through the actual work and payment for services. Communication with Brandon was excellent - If I called or sent a text Brandon would either promptly answer or respond in a very short time. On the scheduled day, Felix Castro (job foreman) and his team arrived on time. Felix explained in detail exactly what he and his team would be doing. On completion of the work, Felix ensured that all debris was removed and provided full details as to what had been done and what he and his team found to be the most likely area of the leak. I am very satisfied with the entire process of working with Brandon who along with Felix and his team provided excellent customer service and would not hesitate to call in again should the need arise. I would highly recommend Brian and Aerotek Environmental to anyone in need of mold remediation services"

FAQs for indoor air quality testing projects in New Castle, DE

You should test your home's air quality if you or your family experience health problems like allergies or respiratory issues, as these could be linked to indoor contaminants. Also, consider testing if you're concerned about mold, radon, carbon monoxide, or if you've recently had home construction, demolition, excavation, or remodeling that could have released chemicals into your indoor air.

An indoor air quality test typically takes one to three hours to complete. After the inspection, you'll receive a detailed written report within two to 10 days. The evaluation includes comprehensive air sampling from all designated areas in your home. Your specialist will review the findings with you and provide clear guidance on steps to take if any issues are found, helping ensure your indoor environment meets health and safety standards.

A certified indoor air quality consultant or inspector is the right professional to perform your indoor air test. While some home inspectors have certifications, they often subcontract this specialized work to trained professionals with advanced tools. This expert will thoroughly evaluate air samples from every area in your home and clearly explain the findings to you. Be sure to confirm your tester's credentials before scheduling your service.
