"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

It's never a good idea to mix chemicals, particularly bleach with an acid like vinegar. Doing so can produce chlorine gas, which is lethal. Choose either vinegar or bleach–or another cleaner, then stick with using that cleaner every time you wash your washing machine.

If you do accidentally mix vinegar and bleach, open a window and leave the area immediately. Take any pets or children with you.

You can throw away moldy things if desired, but you can also clean the mold from certain items. Saving wood furniture by cleaning the mold is possible. You also can clean mold from plastic, metal, and glass materials. It’s far more difficult to clean mold from paper, carpet, cardboard, and mattresses.

If you have the appropriate dehumidifier for the volume in your home then no, they shouldn’t be left on all day. Dehumidifiers have a motor that operates a compressor. In some ways, this is similar to a car and like a car, a dehumidifier needs periods of rest. Ideally, you would run a dehumidifier less than 45 minutes per hour with a break for 15 minutes. Still, this is the upper limit of what you should do.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Mildew and mold are not different—mildew is a specific type of mold and yes, it can become dangerous if left untreated. It would be amazing if we were all biochemists but because we most likely aren’t, it isn’t wise to assume any mold is mildew on sight alone. Harmless mold and toxigenic mold (which can be deadly) look very similar, so if you see any new mold that looks even a little suspect, call a mold professional immediately.
