"**"Do not contact him?he?s a complete scammer and unlicensed. I was looking for an air testing service on Angi, and he called me. I explained over the phone that our newly renovated home had a strong chemical smell, so we wanted an air quality test. He said he could do it and asked for a deposit. About 15 minutes after I paid, I double-checked with him about the testing details, then he told me that he didn?t have the equipment to do the test. Then he refused to refund my deposit. First, he never mentioned the deposit was non-refundable. Second, the cancellation was entirely his fault?he suddenly claimed he couldn?t do the test due to lacking the tools. This is outright fraud: he took my money, won?t return it, and can?t even provide the service. I?ve already filed a complaint with the BBB. Everyone, beware of this scammer!"** "

If you suspect you have mold in your home, basement, attic or commercial building, or are concerned about black mold or toxic mold, call Mold Inspection Service today to schedule a certified mold inspection. We also offer indoor air quality assessments with mold testing and will come take air samples to determine if your indoor mold spore levels are higher than they should be.

Mold Testing and Remediation questions, answered by experts

Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.

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.

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.

Although fiberglass dust is generally not considered toxic, inhaling excessive amounts of it can lead to health risks. Irritation to the respiratory system, eyes, and skin are common effects of fiberglass particle inhalation. While short-term exposure to the dust may only cause temporary discomfort, long-term or chronic exposure can lead to more severe respiratory problems.

Proper safety measures, such as wearing appropriate protective equipment, including masks and goggles, should be observed when handling or working with fiberglass materials to minimize health risks. It is important to note that, unlike asbestos, fiberglass is not associated with life-threatening illnesses.

There are a few signs that might indicate that mold is living behind your drywall. You might notice water stains on your walls or the ceiling, or see the wallpaper begin to peel. Wearing a mask, you could prod at any suspicious areas with a screwdriver; if the wall feels weak or soft, it’s likely there is water damage and possibly mold.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
