Standard home inspectors are not certified in mold detection and testing but can still check for mold using several straightforward methods. This involves looking for visible signs and conditions that create mold growth. Here’s how they typically do it:
Visual inspection: Inspectors look for visible mold growth on walls, ceilings, floors, and other surfaces. They also check areas prone to moisture, like basements, bathrooms, and kitchens. Mold often appears as black, green, or white patches.
Musty odor: A strong, musty odor can indicate the presence of mold, even if it is not immediately visible. Inspectors will note any unusual smells during their inspection.
Water damage: Inspectors look for signs of water damage, such as stains, discoloration, peeling paint, or warped surfaces. Water damage often leads to mold growth, so these signs are red flags.
Humidity levels: While they might not have specialized equipment, inspectors can sometimes use simple hygrometers to measure humidity levels. High indoor humidity (above 60%) can contribute to mold growth.
Leaks and moisture: Inspectors check for leaks in plumbing, roofs, windows, and doors. Persistent moisture problems can create an environment conducive to mold growth.
Ventilation issues: Poor ventilation can lead to mold problems. Inspectors look at ventilation in areas like bathrooms and kitchens, ensuring exhaust fans are working properly to reduce moisture.
If any signs of mold are found, home inspectors will typically recommend further evaluation by a certified mold specialist who can conduct more thorough testing and remediation if necessary. It’s important to address mold issues promptly, as they can affect both property value and health.
