"Absolutely professional! The closest I get to "bad news" is that they test but they don't remediate... because they take avoiding conflict of interest VERY seriously. I will definitely have Bona Fide do the follow-up testing to ensure the contractor does the job right, and would recommend the company to anyone."

"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

Biohazard Remediation FAQs, answered by experts

It’s worth it to get mold remediation as soon as you discover a mold in your home. Mold is a fungus that can be hazardous to your health and cause damage to your home and its belongings. Mold testing and inspections are the best way to know if you have a mold issue in your house. Once detected, call a professional mold remediation company immediately to get it taken care of.

Mold is a fungus that typically grows in warm, moist environments, which is why it's so often found in bathrooms, attics, and under sinks. It survives by digesting decaying organic materials, which makes it very helpful for removing dead plant matter around the world. However, if it starts eating away at your drywall, window frames, and flooring, it can harm your home and your health.

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.

Yes, it is common for mold to grow on the underside of the siding due to the moist atmosphere. When there is an abundance of moisture, mold has the ideal environment to spread and thrive. This fungus can be found on virtually any surface, both indoors and outdoors. Generally, it is most active when the environment is warm, damp, and humid.
