Mold Bros is a local family business, we offer something most of these big businesses cannot: personal, flexible and direct service. There is no 1-800 number to call, no call center, just direct contact with the people who will be helping you remove harmful mold from your home. Being in the northeast we know that our environment is a breeding ground for mold. With a lack of solid options, most companies offer lackluster service and unreasonable prices. We believe that taking care of our customers includes their wallets.

"They are top quality .They were wonderful, professional, timely and did a great job."

"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 There was a red flag for a VOC called Methylene Chloride--Banned outdated paint.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"

Mold Testing and Remediation questions, answered by experts

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.

The four types of hazardous waste are toxic, corrosive, flammable, and reactive. These four types fall under the EPA’s designation of characteristic hazardous waste. The EPA also categorizes hazardous wastes as listed, which includes specific byproducts or unused chemicals from manufacturing and industrial processes, universal waste, including bulbs, mercury, pesticides, batteries, and various other common substances, and mixed waste containing radioactive material.

Dehumidifiers do not directly remove mold or spores from the air. However, by lowering the room’s humidity, spores are less likely to flourish when landing on surfaces.

If you're wondering about black stains on brick at your home, the answer is that you're not looking at efflorescence. While efflorescence can be darker when certain types of salt are involved, black staining is caused by carbon staining, pollution from vehicles, and chimney soot. Black stains can also be caused by organic materials like lichen, algae, or mold.
