"Dave was extremely helpful in giving grounded, low cost solutions for my ongoing mold issue. Proving sound and reliable advice in a sea of so much overwhelming information was invaluable. He took the time to look over a previous report that provided misguided information and recommendations and took the time to walk me through the correct steps saving me so much time and headache. Thank you so so much. I highly recommend this company for their mold services and consult."

Mold Testing and Remediation questions, answered by experts

While bathroom mold, commonly known as black mold, does not produce harmful mycotoxins, it can still pose health risks. If disturbed, mold spores can become airborne and potentially cause allergic reactions, respiratory problems, skin irritations, and other health issues. This is especially true for individuals with allergies or sensitivities. While bathroom molds are not as dangerous as other mold species, prompt action is crucial to mitigate health risks and prevent further spread. 

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.

Some of the signs that could mean your water is contaminated, such as cloudiness or bubbliness, could also be non-problems that don’t affect your water’s potability. However, if your water smells or tastes strange, it’s a good idea to stop drinking it and test it immediately. If your well water is contaminated, the best way to discover that is to test it.

Both an air purifier and a dehumidifier can help prevent future mold growth, but neither can remove existing mold. An air purifier will improve air quality and trap mold spores in the air, whereas a dehumidifier will reduce moisture in the environment. Keep in mind that you need to make sure your air purifier uses HEPA filters, which are rated for mold removal.

You probably have mold on your shower curtains because mold and mildew thrive and spread in warm, dark, wet, and unventilated spaces. Your shower is the perfect environment, especially the shower curtains, because they trap water in the folds and creases, plus they’re exposed to the most water spray. The best way to ensure mold stays off your shower curtains is to keep it dry so it doesn’t have a place to grow. Doing this can also help keep mold off your bathroom ceiling.
