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 There was a red flag for a VOC called Methylene Chloride--Banned outdated paint.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

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.

Unfortunately, asbestos is not easily identified and can often be hidden in plain sight in your home. While it can look like fluffy fibers, tiny pieces can also appear in materials like plastic or cement, making it impossible to identify on your own properly.

Plus, since asbestos is so dangerous when disturbed, you should never root around to try and find it. This job is best for a professional who can test for the material properly.

No, rubber mulch isn’t toxic and is considered safe to use around pets. However, pets, especially dogs, may try to chew on or eat rubber mulch, which can cause choking. Consider monitoring your pets and their behavior when around this mulch type to see how they respond to it.

Not necessarily. If the mold is only on the surface or in small areas, you may be able to clean it effectively without removing all the caulk. However, if the mold has deeply penetrated the caulk or the caulk is damaged or deteriorating, you should remove the caulk completely and replace it to ensure thorough mold removal and prevent future growth.

Living in a house with smoke damage could be safe on a temporary basis, but it depends on the severity and type of smoke damage. If you have major smoke damage or soot present from a fire, you should relocate to keep you and your family safe. Breathing in soot can cause respiratory issues, and it can contain carcinogens, so move out until you get professional remediation done. Your insurance company may cover the cost for alternative housing while your professional works.
