"We spent some time live with molds and we don’t know it was mold. We are trying 2 times to clean it out with some cleaning companies, but it was useless. Finally we got lucky with Bio 911- very professional, sharp, deeply attentive for details, even for our lifestyle depending on appearance of mold and compared with other not expensive. Thank you very much for Bio 911 and personally Kirill for outstanding work."

Customers say: Super punctual

"I found Mold Remedies online and called them up and spoke and met with Richard. We made an appointment the very next day for him to inspect our mold problem. He was prompt and courteous, and he gave us great advice on how to address the issue. He did not charge us, as he told us we could fix the issue on our own. I like that -- he was trustworthy, fair and honest. I will hire him in a minute if I have a big mold issue in the future. (He also coincidentally took care of our neighbor''s home, who had a large mold issue, and they were very happy.)"

"We hired McCormick to remodel our master bathroom, and the process couldn’t have been smoother. Khaled guided us through everything, and his team was skilled and respectful. They handled the job efficiently, stayed within budget, and kept our home tidy. Now, our bathroom feels like a relaxing oasis, with high-quality finishes and a modern touch we love. McCormick’s attention to detail really made the difference, and I’d gladly hire them for future remodels. This experience was everything we hoped for."

"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 questions, answered by experts

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.

Bleach and vinegar are both home remedies for killing mold and mildew, but neither is the best answer. A professional cleaning company or mold remediation company can do the best job. If you want to attempt killing mold yourself, however, reach for plain white vinegar before bleach. Vinegar is a mild acid, and when used properly, it can kill about 80% of mold varieties, along with their spores. It’s also much safer to use than bleach, as it doesn’t include toxic chemicals and isn’t generally dangerous to human or animal health.

The answer depends on the size of your home, the type of mold, and your ventilation systems. However, the best answer would be no, you shouldn’t stay in your home. Arrange to be away from your home during the mold remediation process, as mold is often most dangerous when it’s being removed due to the particles being released into the air. Some contractors won’t proceed with the remediation if you or other household members are in the home.

Mold grows at the fastest rate the environment it’s in will let it. The space between your vinyl flooring and the base flooring it’s on is a perfect environment for mold growth, allowing for rapid spread and contamination. Preventing this involves a proper installation of the flooring and constant humidity control.

Pros will take safety precautions such as sealing areas, using HEPA filters, and controlling airflow.
