Yes, it is possible to have a mold problem even if the air quality test in your home does not show an elevated level of mold. Mold spores are not always present in the air at detectable levels, and they can grow in areas that are not easily visible, such as behind walls, under floors, or in heating and cooling systems.
Mold needs moisture to grow, so if there is a leak or water intrusion in your home, even if it is small, it can create the conditions for mold growth. Mold can also grow on surfaces that are not visible, such as the backside of drywall or under carpeting.
If you suspect that you have a mold problem, even if air quality tests do not show elevated mold levels, it is important to address the issue promptly. Mold can cause health problems, especially for those with allergies or asthma, and it can also damage your home and belongings. A professional mold inspection can help identify any hidden mold and determine the best course of action to remediate the problem.
