By Mike Sweeney

Posted on July 2, 2025

Leasing a modular office or mobile office trailer from Triumph Modular offers a flexible, cost-effective solution for your temporary workspace needs. As our valued customer, you play an essential role in maintaining the safety, comfort, and functionality of your leased space. Routine upkeep helps protect your investment and ensures compliance with lease terms.

Routine Cleaning and Interior Care

Maintain a clean and professional environment by regularly cleaning both the interior and exterior of your leased mobile office. We recommend:

  • Touch-up painting and trim repair as needed
  • Regular floor walks to check for humps, loose tiles, or torn carpet
  • Inspect ceiling tiles for stains, which may indicate water leaks

HVAC System Maintenance

For efficient climate control and air quality in your temporary office space, perform the following HVAC tasks:

  • Replace air filters at least every 3 months (more often in dusty conditions)
  • Run the heating and cooling systems regularly to ensure proper function
  • Test all speeds and settings on A/C units
  • Run the heater occasionally to burn off start-up odors
  • Contact a licensed technician if coils or contactors need cleaning

Roof and Gutter Maintenance

Proper roof and gutter care helps prevent costly leaks or water damage. To keep your unit protected:

  • Clear all roof drains, gutters, and downspouts of debris
  • Inspect roof after storms or heavy snow for bubbles, bulges, or damaged shingles
  • Ensure flashing and drip edges are intact
  • Use a plastic shovel (never metal) to remove snow buildup

Plumbing and Electrical Maintenance

Tenants are responsible for plumbing and electrical hookups. Ongoing maintenance should include:

  • Check for leaks and tighten drain connectors
  • Insulate exposed water lines in cold climates
  • Test lights, switches, and outlets monthly
  • Replace lightbulbs as needed

Structural Safety and Flooring

Inspect structural elements to avoid safety hazards:

  • Walk the floor to spot warping, soft spots, or tile damage
  • Ensure skirting remains intact and free from pest intrusion

Pest Prevention

Reduce the risk of infestations by:

  • Sealing openings and trim gaps
  • Trimming back surrounding vegetation
  • Scheduling professional pest control when needed

Test Safety Equipment

For compliance and safety in your modular office unit:

  • Test smoke detectors and fire extinguishers monthly
  • Replace batteries and recharge equipment as needed

Winterization Tips

If your mobile office will be unoccupied during cold months:

  • Drain all water lines and water heater
  • Turn off breakers and add antifreeze to waste traps
  • Support both hitch and rear to prevent warping
  • Inspect roof seams and caulking before the first freeze
