"It was terrific. They were wonderful. They were punctual. They were true to their words. They cleaned up everything. They were pleasant. I don't have any complaints at all. I will recommend them. The result of the pest after they finished was the mold was gone. They did a very successful clean up. They patched up one of my ceiling, even though it was not their job."

"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"

Mold Testing and Remediation FAQs, answered by experts

According to the Environmental Protection Agency (EPA), hazardous waste is generally classified into four main categories:

1. Characteristic Wastes: These exhibit at least one of four hazardous traits: ignitability (flammable, like gasoline), corrosivity (can rust or decompose materials, like car batteries), reactivity (unstable and can explode, like aerosol cans), or toxicity (harmful when ingested, like lead-based paint).

2. Listed Wastes: These are specific wastes from manufacturing and industrial processes that the EPA has officially designated as hazardous. They include byproducts from processes that use solvents, pesticides, and other chemicals.

3. Universal Wastes: These are commonly generated hazardous items that are subject to streamlined regulations. Examples include batteries, pesticides, mercury-containing equipment (e.g., bulbs), and some lamps.

4. Mixed Wastes: This category includes waste that contains both hazardous and radioactive components, making it subject to regulation by both the EPA and the Nuclear Regulatory Commission.

While an air purifier can trap mold spores and stop them from spreading around your home, it’s not the most effective solution for tackling the problem. Mold is caused by excess moisture and humidity, so there’s a good chance you have an issue somewhere else in your HVAC system that needs to be addressed.

Although you can run a DIY test for mold inside your home by buying a test kit, you won’t know whether the strain of mold is dangerous. The best way to test for mold in a home is to hire a professional who can determine the specific type of mold that you have. If you’re worried you exposed yourself to mold and it’s making you ill, you could request a health test. Your personal doctor could test your urine, take a nasal swab, or test some body tissue to determine your potential exposure to mold.

Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.

If you’ve spotted a skunk or know that one of these furry creatures sprayed one of your family members, your answer is fairly obvious. However, a skunky smell in your house that isn’t coming from these critters may be a sign of a dangerous gas leak. If you suspect this, leave your home immediately and call emergency services. It could also be a build-up of dangerous gas in your home’s septic system or plumbing. Call a professional plumber near you to make an assessment.
