How to Identify a Mold Infestation

1. Persistent musty smell

When mold is hidden behind building materials or in non-visible locations, homeowners must rely on their sense of smell. The spores release volatile organic compounds that produce an odor often described as “musty.” While some stale air can occur in areas without proper ventilation, like a basement, a persistent stench that worsens over time is likely caused by fungus.

2. Year-round allergy symptoms

Most airborne allergens are active for only one or two seasons of the year. For instance, grass pollen is highest from May through August. However, mold growing indoors isn’t impacted by seasonal temperature changes. As a result, many individuals that suffer from a mold allergy will experience upper respiratory issues year-round, such as sneezing, itchy eyes, and a runny nose. Individuals with asthma are also likely to notice an increase in symptoms in the home.

3. Squishy flooring or walls

Building materials can hold a substantial amount of moisture, but it’s likely to occur alongside noticeable damage. With wood flooring, a springiness can occur, while drywall and vinyl or laminate flooring are prone to bubbling. These issues commonly coincide with mold and are particularly common after a water-related problem occurs, such as flooding or sewer backups. For that reason, water and mold mitigation needs to occur as soon as possible after major moisture events.
