How to Protect Your Commercial Property from Summer Humidity and Mold Growth

Summer in Northeast Ohio brings not only higher temperatures but also elevated humidity — the perfect conditions for mold growth if your commercial property isn’t prepared.

Mold can threaten tenant health, damage your facility, and interrupt business operations, making proactive prevention critical for commercial property owners and managers. Here’s how you can protect your building from moisture challenges during the hot summer months:

1. Understand Mold’s Ideal Conditions

Mold thrives in warm, damp environments with poor airflow. During Northeast Ohio’s humid summers, condensation and elevated indoor moisture create ideal breeding grounds, especially in:

• Basements

• Storage or utility rooms

• Mechanical spaces

• Areas with roof leaks or plumbing issues

Recognizing these high-risk zones is the first step to prevention.

2. Maintain Proper Ventilation

Good ventilation helps control humidity and improves airflow, reducing stagnant, damp conditions where mold can develop. Property managers should:

• Ensure HVAC systems are maintained and operating properly

• Check that exhaust fans are working in restrooms, kitchens, and other moisture-prone spaces

• Consider adding dehumidifiers in problem areas

3. Address Water Intrusion Immediately

Heavy rain and storms in Northeast Ohio can lead to roof leaks, drainage backups, or flooding. Quick action is essential:

• Inspect roofs, windows, and doors for leaks

• Check and clean gutters and downspouts

• Repair any water damage as soon as possible

4. Control Indoor Humidity Levels

Keeping indoor humidity between 30% and 50% is recommended to prevent mold growth. You can:

• Install or calibrate humidity sensors

• Use commercial-grade dehumidifiers where necessary

• Schedule routine checks of HVAC systems to monitor moisture controls

5. Educate Tenants and Staff

Encourage tenants, employees, and maintenance teams to report any signs of mold or moisture right away. Mold can often develop behind walls or under flooring before becoming obvious, making early detection critical.

6. Work with a Professional

If mold does appear, partner with a professional mold remediation contractor to ensure it is safely and thoroughly removed. Professionals can also help you create a long-term moisture prevention plan customized for your property.
