Mold growth in a commercial building can be difficult to detect. It often begins as small spots on walls, ceilings and floors that are difficult to see with the naked eye. Spores spread quickly throughout a building if it isn’t taken care of immediately, so knowing where it’s likely to grow is important for preventing a major infestation. A mold infestation needs the right environment, and there are six common places in your business that are perfect for mold growth. 

1. Mold in HVAC System

When it comes to the HVAC system, mold can grow on the indoor air unit, the drain pan, and the ductwork.

There are two main reasons why this occurs: 1) there is a lack of proper ventilation in your building because of poor design or improper maintenance; 2) there is excessive moisture or condensation in these areas as a result of leaks or clogging up with dust or dirt (from lack of cleaning!).

Mold growth on these surfaces can be quite difficult to remove. If you have any concerns about mold growth in a commercial building, then call Burggraf today for mold help!

2. Bathrooms with Mold Damage

Bathrooms are a common place to find mold because they tend to be warm, humid, and have a lot of moisture. If you have a leaky faucet, shower-head or water damage in your bathroom, mold can grow easily on surfaces like walls/ceilings. Mold can also grow on things like shower curtains or stall doors where there’s excess moisture from frequent use of the fixtures. Finally, if there are cracks in your cement subfloor that allow water seepage below the surface (or if you have floor drains), it’s possible for mold spores to get into those crevices, too. 

3. High Humidity Areas (basements and crawl space)

Wet areas are not the only places where mold can grow. Areas with high humidity are also common sites for mold growth, like basements and crawl spaces. When water is continually introduced in these spaces because of plumbing leaks or condensation buildup, it creates a perfect opportunity for mold to thrive. Even if there is no actual moisture present in these spaces, high levels of humidity create an environment where molds can quickly develop and spread throughout your building. This includes onto drywall surfaces inside your office and frequently visited areas in your commercial space. Basements and crawl spaces are not the only high humidity areas in your building. Keep an eye on areas that seem more humid than others, and get a hygrometer if you suspect you have too much humidity in one area. 

4. Kitchen Mold Damage

The kitchen is a common place for mold to grow. It’s a place where warm, moist air can easily collect. The sink and dishwasher drain pipes are common spots where you might find mold growing. If your building has an exhaust fan that runs continuously or periodically, this can also create a good environment for mold growth in the kitchen because of its constantly moist conditions.

5. Mold within Roof 

Roofs can easily collect mold because they’re exposed to rain, snow and sunlight. Because mold likes a warm and moist area, the roof of your business is a primary spot for mold growth. 

Roof surfaces can be subject to moisture intrusion from groundwater or accumulated precipitation on the surface itself. This is especially true if your building has flat roofs. If the roof  isn’t sloped for drainage, the precipitation can lead directly down into the building structure below. There may be water damage occurring as a result of this infiltration into your building’s interior walls, floors and ceilings. 

6. Mold Found Under Carpet

If you have carpet in your business, it could be hiding a moldy mess. Mold can grow both in the padding of your carpet and behind it. If you suspect your office has a problem with mold, inspect the padding to look for any signs of damage or discoloration. You may also want to look at the subfloor and floorboards above air vents and air currents are likely to blow around dust and debris.

There are many different places you might see mold growth in a commercial building, but if you’re looking to avoid it all together, try to keep these areas clean and dry. The best way to do this is by taking care of your HVAC system and changing filters regularly, at least once every three months. If you notice any signs or symptoms of mold growth in your building, then contact our certified professionals who will assess the damage and get to work quickly.
