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 There was a red flag for a VOC called Methylene Chloride--Banned outdated paint.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

The duration of mildew smell in carpets depends on several factors, including the extent of moisture, cleanliness, and ventilation. If promptly addressed, the smell can diminish within a few days to a couple of weeks after thoroughly drying and cleaning the carpet. However, in severe cases or if not properly treated, the smell might persist. Persistent odors could indicate deeper mildew growth, requiring professional cleaning or, in extreme cases, carpet replacement to completely eliminate the smell.

Many types of mold spores and fungi spores are constantly present in the air, but they need a friendly surface and moisture to grow. Should some of these spores land on paper or wood with significant moisture present—such as drywall with a paper cover that is soaking up water from a leak—mold or fungi could begin growing. Dampness from leaky pipes, condensation on windows, leaks in a roof, flooding in a basement, or high, prolonged humidity in a small area all can create the excess moisture that mold and fungi need to grow in your home.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.

Yes, mold can build up in a dehumidifier if not properly emptied and clean. Clean it every few weeks by removing dirty water, scrubbing with a mild dish soap, and allowing it to fully dry before reassembling. 

If high moisture levels have led to mold growth on your drywall, mold remediation may be your best bet. The average cost of mold remediation is $2,400 , but the total price depends on how much you need to repair and the location. Removing mold from drywall may cost you between $300 and $825 , but the overall price could be higher if you need to fully replace several walls in your home.
