Identifying Mold Growth in Commercial Buildings: Common Places to Look Out For

5/15/2023 (Permalink)

As a disaster restoration company, we often receive calls about mold growth in commercial buildings. Mold can cause structural damage, so it's essential to identify and address mold growth promptly. In this blog, we'll discuss the common places to find mold in a commercial building, so you know where to look out for it.


Bathrooms are one of the most common places to find mold in commercial buildings. The high humidity and moisture from sinks, showers, and toilets create a perfect environment for mold growth. Mold can grow on the walls, ceilings, floors, and grout of the bathroom. If you see discoloration or stains on these surfaces, it may be mold growth.

HVAC System

The HVAC system in a commercial building can be a breeding ground for mold. Mold can grow in the air ducts, evaporator coils, and drip pans of the HVAC system. If the HVAC system is not properly maintained, mold spores can spread throughout the building, causing hazards and structural damage.

Roof and Ceiling

A leaking roof or damaged ceiling can lead to moisture buildup, which can cause mold growth. If you see discoloration or stains on the ceiling, it may be an indication of mold growth. In addition, mold can grow in the insulation and walls surrounding the roof and ceiling.

Basement and Crawlspace

Basements and crawlspaces are often damp and humid, which makes them an ideal environment for mold growth. Mold can grow on the walls, floors, and ceilings of these areas. If there are any leaks or water damage, it can lead to mold growth. It's essential to monitor the humidity levels in these areas and address any water damage promptly.


Kitchens can be a hotbed for mold growth, especially if there are plumbing issues or leaks. Mold can grow on the walls, ceiling, floors, and cabinets of the kitchen. It's essential to monitor the plumbing system and address any leaks or water damage promptly to prevent mold growth.

In conclusion, mold growth can be a serious issue in commercial buildings. Bathrooms, HVAC systems, roofs and ceilings, basements and crawlspaces, and kitchens are some of the common places to find mold in a commercial building. If you suspect mold growth in your commercial building, it's essential to consult a professional disaster restoration company, such as our SERVPRO of Commerce City team. They can assess the extent of the damage and recommend the appropriate course of action to address mold growth safely and effectively.
