"Mold Neutralizers is the best in the business! I should know because mold has displaced me three times. For years I suffered through unusual and devastating health symptoms. When I finally had an appointment with a functional medicine doctor, she told me I had mold toxicity, and that I should have my home inspected. I could not believe it. My house was pristine, but I called Mold Neutralizers because I was very sick and needed answers. It was the best decision I have ever made because mold was found hiding under my bathroom vanity and in my HVAC system. From that moment on Mold Neutralizer went to work. Their expert team isolated the mold, and I hired them to remediate. At every turn they went over and above to help me. I sincerely thank every one of them. Because of them I feel safe again. Mold Neutralizers are experts in their field. They are honest. They are caring. Dont hesitate to call them! Ronda"

"Larry answered my call and explained why we have no need to remediate what was safe in its present condition, notwithstanding the re-roofing we are about to perform on the house. In other words, although he could have suggested we engage him for some remediation work for which I apparently would have had no need, he was honest and talked me out of paying for something I did not need. Class act."

"We discovered we had mold in our home after we had a leak. Matt and his team tested our home for mold, then we completed the dry fog remediation treatment. They gave me post tests to show the mold has all been killed. They were very thorough everything went just as planned. Excellent job, I am very impressed!"

"Noah scheduled an estimator to come to my house 30 minutes after my phone call. Moises came and gave me a reasonable price. He was prompt and courteous. The next day Hiram and Orge came to do the work. They were prompt and friendly. They did an excellent job removing the mold. Brian called me to keep me appraised of what they did and how long they will be leaving the dehumidifier and other drying equipment in the garage. This company is prompt, professional, and courteous and did an excellent job. I would definitely use them again."

"I had a great experience with Quality Restoration. Adrian came out quickly to assess the mold remediation damages, explained everything clearly, and gave me a very fair quote. He started the work right away, which I really appreciated. The remediation process went smoothly and we received passing clearance testing results. Now they’ll be starting the repairs soon. Adrian has been professional, responsive, and easy to work with throughout the entire process. Highly recommend Quality Restoration if you need mold remediation or restoration work done."

Mold Testing and Remediation questions, answered by experts

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.

It’s unlikely your leaves are a hazard, especially if you get to them while they’re dry. However, a couple of rare risks exist. University studies suggest that decaying leaves can produce organochlorines, toxic pollutants similar to man-made PCBs (polychlorinated biphenyls), so avoid keeping them in an enclosed area.

Also, leaves and compost may cause the growth of fungi that can cause diseases like histoplasmosis and aspergillosis, as well as mold spores that are unhealthy for human lungs. Again, severe issues are rare, but those with compromised immune systems or allergies to mold should wear face masks when directly handling leaves.

If you’re worried mold might still be lingering after you’ve cleaned your items, here are signs to watch for:

  • Musty smell

  • Visible spots or stains

  • Allergy symptoms when you’re around the item

  • Damp or sticky feel.

If you notice these signs, it might be time to let go of the item or get professional treatment.

No—there are key things that help you determine if it’s mold versus mildew. Mildew is a specific type of mold. Both can trigger allergies, asthma, and respiratory symptoms, though mold is typically more severe than mildew.

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.
