"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

"Mike Smith, The Mold Hunter, Inc., was an extremely easy and professional mold remediation company to work with. Mike was prompt with communications throughout the process, answered all our questions and gave detailed explanations of what was going to be done from testing to remediation, and he provided a detailed and accurate estimate of the cost. His employees were very thorough, competent, and respectful of our property. Mike even gave suggestions as to how we could do some preparation ourselves in order to save money. What more could you ask? We highly recommend Mike for testing and mold remediation."

Mold Testing and Remediation FAQs, answered by experts

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. 

Most grass mold isn’t harmful to humans. Slime molds in particular aren’t toxic and may even possess some benefits. Other molds, like powdery mildew and snow mold, generally aren’t a concern, but can still cause allergic reactions and respiratory distress in those with high allergy risk and compromised immune systems.  

Several factors affect the color of mold, including humidity levels, age of the mold, and amount of light it receives. A patch of mold that starts out green may darken and turn black as it ages. A species of mold may be green if growing in one environment, but be black in another environment. Color usually isn't a reliable way to determine mold species or risk.

If you would like the insurance company to potentially help you pay for the mold remediation, you need to inform the insurer. When you notify your insurance company, they may say that you need a mold inspection before receiving any money for mold remediation. It’s possible that the insurer would not pay for this inspection unless they find mold.
