"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

Yes, mold can grow under your shower tiles if they aren’t thoroughly waterproofed. Even if you have a durable, non-porous tile material, water can make its way through grout or gaps around the edges of the shower. This will slowly erode the grout, which can cause tiles to come loose. It can also trap moisture behind tiles, and within a day or two, mold and mildew can rapidly grow.

While fiberglass dust is not generally considered toxic, inhaling the fibers can cause irritation to the respiratory system, eyes, and skin. Short-term exposure may lead to temporary discomfort, including coughing, throat irritation, and shortness of breath. However, prolonged or chronic exposure can result in more severe respiratory problems. Unlike asbestos, fiberglass is not associated with life-threatening illnesses. To minimize health risks when working with fiberglass materials, it is essential to use proper safety measures, such as wearing protective equipment like masks and goggles.

Painting over mold is not an effective solution and can actually make the problem worse. Instead, it traps moisture, which allows mold to grow and spread beneath the surface. Mold must be completely removed before painting to ensure the problem doesn’t recur. If mold is painted over, it may eventually seep through the new layer of paint, causing discoloration and peeling.

Odors, humidity problems, and health symptoms like headaches or allergies.

Yes, mold under silicone caulk can potentially cause health issues, which may be more noticeable in people with asthma, allergies, or other respiratory conditions. Mold releases spores into the air, and inhaling these spores can cause symptoms such as coughing, sneezing, eye irritation, and skin rashes. It's important to address mold issues promptly to protect your health.
