The U.S. Department of Housing and Urban Development (HUD) recommends that all people purchasing a home have it tested for mold by a qualified professional. Inhaled mold spores are known to cause potential health issues in some people, which are usually similar to allergy symptoms. In addition, some molds produce potentially toxic substances called mycotoxins. People with respiratory diseases like asthma or COPD, allergies or compromised immune symptoms are generally most prone to mold related health problems. If a significant mold problem is present, it means water/moisture is also a problem, which can lead to major structural damage. Even if a mold problem is not noticeable, you could be breathing in mold spores that are potentially harmful. For the safety of your family and home, having a professional mold inspection done is a wise investment.
