"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

Knowing what to expect during a mold inspection can help make the process easier. Prepare by closing doors and windows for 48 hours, turning off HVAC systems for at least two hours, and avoiding disinfectant chemicals for at least 48 hours. 

The mold inspection process takes between 24 and 48 hours. Your professional will check walls, fireplaces, air ducts, vents, and windows for visible spores. They will also take an outdoor base air sample. Your pro will send these samples to a lab for testing and advise you on the findings.

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.

While home mold tests can provide a simple identification of mold presence, they lack accuracy and reliability. These kits may detect mold spores but can't pinpoint the source or identify the type. Professional testing, combined with an inspection, is more comprehensive and leads to actionable next steps. 

Poor maintenance can cause some health concerns, although these are more common in commercial misters than residential versions. For example, stagnant water can become a breeding ground for bacteria, some of which can be dangerous to human health, especially when inhaled. Regular flushing of the system before seasonal use should prevent issues like these.

Otherwise, avoid using mosquito misters with pesticides or plant misters with fertilizers near humans. These misters are not designed for cooling sprays around decks or patios, but for more utilitarian purposes.

Areas of your home may provide an ideal environment for green or black mold. Most molds love moisture and will thrive in wet or damp areas. Some types of mold, such as Stachybotrys chartarum, grow well on materials commonly used in homes, such as gypsum board and wood. Mold may also grow in areas where there are leaks, such as in bathrooms, kitchens, or basements.
