Easy Steps to Avoid Moisture-Related Damage

When summer arrives, so does the problem of humidity in commercial buildings. High relative humidity (RH) impacts building materials, indoor air quality, and the functioning of HVAC systems. Here are some tips for identifying common problems and what to do about them.

Risks of High Humidity

When the RH hits 60% or above, conditions become ideal for mold growth. Drywall, ceiling tiles, and carpeting can absorb and keep moisture even after removing a water source. Condensation collects on cold surfaces, particularly in mechanical rooms or regions with limited ventilation.

This moisture buildup can affect sensitive assets such as electronics, archived records, and merchandise. Warning signs include warped wood, rusted hardware, and persistent odors pointing to inadequate moisture control.

Building Systems that Support Drying

The HVAC system is central to indoor moisture control. It must be the right size for the square footage and maintained to regulate temperature and RH. Inefficient systems, or those that short-cycle, often fail to dehumidify effectively.

Steps to Lower RH

To ensure effective humidity control in commercial buildings, keep HVAC drain pans clean and condensate lines free to avoid water buildup. Filters should be updated regularly to maintain maximum airflow and system efficiency. In high-traffic areas where regular HVAC performance may be inadequate, consider installing a specialist dehumidifier—low-grain refrigerant (LGR) devices are particularly effective. Additionally, incorporating data loggers or building automation systems enables continuous monitoring of relative humidity (RH), assisting facility managers in identifying and addressing moisture concerns before they worsen.

Everyday Steps Facility Managers Can Take

  • Seal leaks and air gaps: Prevent humid outdoor air from entering through windows, doors, or utility penetrations.
  • Ventilate properly: Install or maintain exhaust fans in high-moisture areas like restrooms or kitchens.
  • Be mindful of indoor plants: Overwatering can increase humidity and create localized condensation.
  • Limit porous flooring: Avoid carpets in areas prone to moisture.
  • Inspect hidden spaces: Mechanical chases, ceiling voids, and closets often harbor unnoticed humidity and mold.

When to Call a Restoration Professional

If you observe visible mold, musty odors, or unexplained water stains, it’s time to call certified professionals. Technicians trained in water damage and microbial remediation use thermal imaging, hygrometers, and air sampling tools to diagnose and address issues thoroughly.

For complex environments—such as data centers, healthcare facilities, or manufacturing plants—more advanced techniques like Small Particle Remediation (SPR) and HEPA filtration may be necessary to restore safe conditions.
