"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"

"Satisfied overall. Service was very prompt and friendly. Air test had to be redone so that was an inconvenience. My biggest complaint is that the explanation of results was vague so I had trouble understanding the severity or health consequences of my situation. It was impossible for me to justify the cost of remediation when I didn't even understand the problem."

"Ongoing water intrusion from our windows over the years led to mold issues throughout several rooms in the house. After bringing out three different companies to evaluate the situation, Steven and the team at Nexgen Property Restoration stood out right away. They were fair on pricing and offered a non insurance discount since we chose to handle everything out of pocket. With multiple areas needing to be opened up, that savings really helped. The remediation process was handled professionally from start to finish and the quality of work gave us the confidence to move forward with them for reconstruction as well. Having one company manage everything made the process a lot easier. The final result came out great and their warranty gives us peace of mind moving forward. Definitely recommend Nexgen if you?re dealing with paying out of pocket"

Mold Testing and Remediation FAQs, answered by experts

If you believe mold is hidden somewhere in your home, don’t delay inspecting it, as it can be dangerous, especially to people with breathing problems and allergies. While it’s possible to learn how to check for mold yourself, we advise most people to hire a professional mold inspector, who can look more thoroughly. You can also purchase mold test kits if you aren’t sure if your home has mold, but a true human inspector is still your best bet.

According to the EPA, mold allergies are common and can cause skin irritation, respiratory problems, headaches, and other allergic reactions. Mold allergies can also trigger asthma attacks in people with asthma. Additionally, some molds produce mycotoxins, which can lead to very serious conditions, like lung cancer.

Professional carpet cleaning can cause mold if the job is not done properly. There are two ways this can happen—if your carpet cleaner fails to dry the carpet properly, or if your carpet cleaner uses an excessive amount of water during the cleaning process. Mold can grow wherever moisture is present, so make sure you hire a pro who knows the process inside and out.

Before you start removing mold, turn off the furnace. Clean away any visible mold from accessible areas using a mixture of water and mild detergent. Change air filters and check for moisture sources like leaks. If the problem persists or it's widespread, hire a local HVAC company for professional cleaning.

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.
