Humidity Control for Gym Floor Installation: Protecting Materials & Deadlines

Installing a new gymnasium floor is a significant investment for any school or facility, and success depends on more than just skilled craftsmanship.

Humidity control is critical — especially during the hot, humid summer months when excess moisture can warp wood, delay progress, and jeopardize the entire project.

That’s why a high school contractor in Illinois turned to Garrett McKenzie for a temporary dehumidification solution that kept materials safe and ensured the project stayed on schedule.

The Situation:

During summer recess, a new gymnasium floor was slated for installation at an Illinois high school. With high seasonal humidity posing a serious threat to wood flooring, the contractor sought reliable climate control to stabilize conditions inside the gym.

The challenges were clear:

• Control interior humidity to protect sensitive wood flooring
• Condition a specific indoor area (the gymnasium)
• Manage equipment access with limited site entry options

The Response

Garrett McKenzie began by assessing the space, measuring cubic footage, and analyzing anticipated humidity levels.

Based on this evaluation, our team deployed a 5,000 CFM desiccant dehumidifier, a unit well-suited to manage indoor conditions for large spaces like gymnasiums.

To overcome access issues, our crane-equipped delivery vehicle was used to place the unit on-site safely. The dehumidifier was connected to house power, with ducting routed directly into the gymnasium. Temporary ductwork and layflat extensions ensured even airflow distribution across the space.

The Execution

Despite logistical challenges, the installation was completed quickly by Garrett McKenzie technicians.

Within just two hours of startup, the dehumidifier had reduced the gym’s relative humidity to below 15% — creating a stable, dry environment ideal for flooring installation.

By providing site-specific layout planning, equipment setup, and on-site technician support, we ensured the contractor could begin flooring installation without delay or risk of material damage.

The Result

The new gymnasium floor was installed successfully, without issues related to moisture or warping.

By deploying the right equipment and tailoring the solution to site conditions, Garrett McKenzie kept both the materials and project timeline fully protected.

This case highlights our role as a trusted partner for commercial contractors who require reliable climate control solutions to protect investments and maintain tight deadlines.
