  • Why should I inspect for mold?

    Scientific studies have revealed that the air inside of homes and buildings can sometimes be more polluted than outside air. When mold is found thriving in indoor environments, the health risk or hazard to susceptible individuals can increase significantly. At particular risk, can be children, the elderly, or the chronically ill, and those who suffer from respiratory ailments, such as allergies, or asthma.


    Mold inspections are sometimes requested when the fungal contamination indoors exceeds an individual's ability to perform adequate clean up, or when the occupant is suffering from suspected mold associated health problems. Professional mold inspection services are frequently requested when fungal contamination exceeds ten square feet and is beyond a person or company's ability to safely clean up, or when unseen contamination is creating mold odors, or health concerns, or when the presence of mold is involved in imminent litigation, or a physician is trying to isolate a harmful organism. Consumers can contact professional mold inspection services, such as those provided by Bay Cities Mold Inspection.
