"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 questions, answered by experts

Signs you may need mold remediation include visible mold growth on walls or ceilings, a persistent musty odor, or health symptoms like allergies and respiratory issues. Areas affected by water damage or excessive humidity are prone to hidden mold. A professional inspection can confirm whether mold remediation is required, especially for large or concealed infestations.

Mold thrives in wet and humid conditions, and the bathroom can often be an ideal place for it to grow. If you are worried about mold, it's a good idea to hire a local mold inspector to inspect your bathroom. 

How you handle the mold depends on the extent of the issue. If it's on the caulk or other surface, a deep cleaning with mold-killing products such as vinegar or bleach may be sufficient. For a large infestation, you'll most likely need professional mold remediation.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Mold grows quickly. It typically begins to grow on drywall about 24 hours after exposure to moisture or humidity. Drywall is a porous material, which makes it particularly hospitable to mold growth. 

While mold growth begins after just a day or so, it can take a few weeks before the evidence becomes visible. Mold spores will typically appear on the drywall surface within three weeks of growth starting.

Many caulk alternatives are safe for use in kitchens and food preparation areas, provided you apply them correctly and let them cure for the right amount of time. If you’re unsure about this step, call in a pro to do it for you. Silicone putty and caulk strips are often used around sinks and countertops due to their waterproof and flexible nature. Always choose products labeled as safe for kitchen use and follow the manufacturer's instructions for proper application and curing.
