A comprehensive maintenance guide for property managers and building owners. Covers cleaning protocols, inspection checklists, maintenance schedules, and repair vs replacement decisions for storefronts, office buildings, and commercial properties.

The diagram below identifies the critical inspection points on a typical commercial storefront. Each numbered point requires regular examination during maintenance inspections.
Following a structured maintenance schedule prevents costly emergency repairs and extends the lifespan of your commercial glass installation. Below is a recommended schedule for typical commercial properties.
| Frequency | Task | Performed By | Purpose |
|---|---|---|---|
| Weekly | Clean entrance glass doors and sidelights | Janitorial staff | Appearance and hygiene |
| Monthly | Clean all interior glass, partitions, and mirrors | Janitorial staff | Appearance and tenant satisfaction |
| Monthly | Check automatic door operation and sensors | Maintenance staff | Safety and ADA compliance |
| Quarterly | Clean exterior storefront and window glass | Professional window cleaning | Appearance and longevity |
| Quarterly | Inspect door hardware (hinges, closers, pivots) | Maintenance staff | Prevent glass stress damage |
| Semi-Annual | Full professional glass inspection | Glass contractor | Identify seal failures, cracks, safety issues |
| Semi-Annual | Automatic door operator service | Door operator technician | Manufacturer warranty compliance |
| Annual | Weather seal and gasket replacement assessment | Glass contractor | Prevent water and air infiltration |
| Annual | Energy performance assessment | Energy auditor | Identify degraded IGUs and efficiency losses |
| As Needed | Emergency glass repair or board-up | Glass contractor | Safety, security, weather protection |
Use this checklist during your semi-annual professional inspections. Each item should be assessed and documented with photos and condition ratings.
Proper cleaning technique extends the life of commercial glass and maintains its appearance. Improper cleaning is one of the most common causes of premature glass degradation.

Commercial glass should receive a professional inspection at least twice per year -- ideally in spring (after winter weather stress) and fall (before winter weather). High-rise buildings, properties in high-wind corridors, and buildings with extensive curtain wall glazing should be inspected quarterly. After any severe weather event (high winds, hail, or temperature extremes), an additional inspection is recommended. Regular inspections identify seal failures, stress cracks, hardware wear, and safety concerns before they become expensive problems.
Use pH-neutral glass cleaners or a solution of mild dish soap and water. Avoid ammonia-based cleaners on Low-E coated glass (interior surface) as ammonia can damage the coating over time. Never use abrasive cleaners, razor blades on tempered glass (risk of nickel sulfide scratch damage), or pressure washers at close range on sealed IGUs (can damage seals). For hard water stains on exterior glass, use a commercial hard water remover containing oxalic or phosphoric acid, followed by thorough rinsing. Always test any new cleaning product on a small inconspicuous area first.
Commercial glass should be replaced when: IGU seals have failed (fogging between panes), cracks extend across the glass or reach the edge, tempered glass has any chip or crack (risk of spontaneous failure), safety glass labels are missing in required locations, glass does not meet current building code requirements, or energy performance has degraded significantly. Repair may be viable for: minor surface scratches (can be polished), small chips in non-tempered glass away from edges, failed caulking or gaskets (resealable), and hardware issues (hinges, closers, pivots) that do not affect the glass itself.
The most common commercial glass issues in the DMV area are: (1) IGU seal failure causing fogging between panes -- typically occurs after 15-20 years or sooner with direct sun exposure; (2) failed door closer mechanisms causing glass doors to slam and stress glass; (3) hard water staining from sprinkler systems hitting glass facades; (4) thermal stress cracks starting at the glass edge, especially on tinted or coated glass; (5) failed weather seals allowing water infiltration; and (6) scratched glass from improper cleaning techniques or construction debris.
Automatic glass door maintenance should include: monthly cleaning of the glass panels and sensors, quarterly lubrication of pivot points and track systems, semi-annual inspection of the automatic operator motor and control board, annual replacement of weather seals and sweeps, and immediate attention to any unusual sounds, slow operation, or sensor malfunctions. The automatic operator should be professionally serviced per the manufacturer schedule (typically semi-annually). Keep the floor track clear of debris, and ensure the safety sensors are clean and properly aligned.
A commercial glass maintenance contract is a scheduled service agreement that includes regular cleaning, periodic inspections, priority emergency response, and discounted repair rates. Typical contracts include bi-annual professional inspections with detailed condition reports, quarterly or monthly cleaning service, 24/7 emergency response with guaranteed arrival times, preferred pricing on replacement glass and hardware, and a single point of contact for all glass-related needs. Expert Glass Repair offers customized maintenance contracts for commercial properties throughout the DMV area.
Preventive measures include: installing protective film on ground-level glass in high-traffic areas, adjusting automatic door closers to prevent slamming, redirecting sprinkler heads away from glass surfaces (prevents hard water staining), maintaining proper HVAC temperature consistency (prevents thermal stress cracks), trimming landscaping away from glass surfaces, installing bollards or barriers in vehicle-traffic areas, and scheduling regular professional inspections to catch issues early. A proactive maintenance program costs significantly less than reactive emergency repairs.
