Why Fenestration Inspections Matter in Commercial Properties

Doors, windows, and other fenestration components are often taken for granted in commercial buildings, but they play a critical role in energy efficiency, occupant safety, and building performance. According to the U.S. Department of Energy, commercial buildings lose an estimated 30% of their heating and cooling energy through inefficient windows and doors. Beyond energy loss, poorly maintained fenestration can compromise life safety, accessibility, and even security.

Common Issues We See

• Damaged or deteriorated seals around windows and doors leading to water intrusion

• Broken or misaligned hardware affecting door function and security

• Fire doors with missing labels, excessive gaps, or obstructed operation

• Inoperable or poorly fitted emergency egress doors and windows

• ADA access barriers, such as heavy or non-compliant door closers

Even small deficiencies in fenestration systems can create safety risks, liability exposure, and higher operating costs.

What Our Fenestration Inspections Include

Aligned with the CCPIA Commercial Standards of Practice (ComSOP), Guardian’s inspections are visual evaluations that typically cover:

• Observation of exterior and interior doors and windows for condition and operation

• Identification of gaps, seal failures, and weatherproofing concerns

• Verification of visible fire door labeling and closure

• Review of accessibility and egress requirements

• Documentation of hardware function and safety concerns
