5 Compelling Signs That Your Commercial Building Has Mold

Mold is a type of fungus that can grow in damp environments, and it is often found in buildings where moisture is present. Commercial buildings, in particular, are at a higher risk of mold growth due to their size and complexity. 

If left unchecked, mold can cause health problems for the building’s occupants and structural damage to the building itself. In this article, we will discuss five compelling signs that your commercial building has mold.

1) Odor

The smell of mold is often described as musty or earthy, and it can be a clear indication that mold is present in the building. This odor is caused by the microbial volatile organic compounds (MVOCs) that mold produces. MVOCs can be released into the air by active mold growth or when the mold is disturbed. 

The smell can be particularly strong in areas with high humidity, such as basements, bathrooms, and kitchens. If you notice a persistent odor that you cannot identify, it is essential to investigate the source. 

2) Visible Mold Growth

Another sign that your commercial building has mold is visible growth. Mold can appear as black, green, brown, or white spots on surfaces. It can grow on walls, ceilings, floors, carpets, and even furniture. 

If you see any signs of mold growth, it is essential to take action immediately. Mold can spread quickly and cause significant damage to the building’s structure and its occupants’ health.

3) Water Damage

Water damage is a common cause of mold growth in commercial buildings. When water damage occurs, it provides a perfect environment for mold to grow. If left unchecked, mold can begin to grow within 48 hours of exposure to moisture. 

This means that if your building has experienced any form of water damage, such as leaks, flooding, or burst pipes, it is essential to act quickly to prevent further damage. Inspecting the affected area for signs of mold growth is crucial, as mold can cause structural damage to the building and health problems for the building’s occupants. 

4) Respiratory Problems

Mold can cause a range of health problems, particularly for people with respiratory issues. Exposure to mold can cause symptoms such as coughing, wheezing, and shortness of breath. If your building’s occupants are experiencing respiratory problems, it is essential to investigate the cause and take action to prevent further exposure.

5) Increased Humidity

High humidity levels can create an environment that is conducive to mold growth. If your building’s humidity levels are consistently above 60%, it is essential to take steps to lower them. 

This can be achieved through proper ventilation, dehumidifiers, and air conditioning systems. By reducing the humidity levels in your building, you can prevent mold growth and improve the overall air quality.


Mold growth can be a significant problem in commercial buildings, and it is essential to take action to prevent and control it. If you notice any of these signs in your commercial building, it is essential to take action immediately.
