If it fails: the first hour
What the site contact should do before the technician arrives.
- Clear broken glass from walkways to prevent injury
- Photograph the damage for insurance before boarding
- Call for emergency board-up service
- Restrict customer or public access to the immediate area
What fails
What a service call includes
- Assess whether the glass is tempered, laminated, or an insulated unit before ordering replacement
- Board or temporarily secure a broken panel to close the security gap immediately
- Measure and order code-compliant replacement glass matched to the opening
- Remove old glazing bead and gaskets and re-glaze with new material
- Replace failed insulated glass units rather than just the visible pane
- Repair or reinforce a damaged frame before resetting glass
- Verify replacement glass meets safety glazing requirements for the location
- Clean and inspect surrounding frame and hardware during the same visit
Preventive checklist
The items a maintenance program should carry for this system. Build a combined checklist across systems with the checklist builder.
Quarterly
- Inspect glazing beads and gaskets for cracking
- Check for stress cracks starting at panel edges or corners
- Look for fogging between panes on insulated units
Annual
- Full frame inspection for corrosion or looseness affecting glass fit
- Verify safety glazing compliance in door and low-height locations
- Check caulking and weatherproofing around glass perimeters
What it costs
| item | typical range | what moves it |
|---|---|---|
| Emergency board-up | $150 to $400 | Priced by panel size and after-hours response requirements. |
| Tempered glass panel replacement | $300 to $900 | Larger storefront panels and custom sizes push toward the higher end. |
| Insulated glass unit replacement | $500 to $1,500 | Cost depends on unit size and whether low-E or other coatings are specified. |
| Laminated safety glass replacement | $400 to $1,200 | Used in higher-risk or sound-dampening applications, priced higher than standard tempered. |
| Reglazing (gasket and bead replacement without new glass) | $150 to $400 | Lower cost fix when the glass itself is intact but the seal has failed. |
National ranges. Local labor, access, after-hours timing and materials move them. Multi-site programs usually price below one-off calls.
When this is an emergency
A shattered or missing storefront panel counts as an emergency because it leaves the space open to weather, pests, and unauthorized entry.
How to choose a provider
- Ask whether the provider stocks common storefront glass sizes or has to special-order
- Confirm they can identify and match tempered, laminated, or insulated glass correctly
- Ask about after-hours board-up response time separate from the permanent repair
- Get a quote that specifies glass type, thickness, and whether the frame needs work too
- Ask if they check safety glazing code compliance as part of the estimate
Questions
Why did the glass crack with no impact?
Stress cracks can develop from thermal expansion, a small edge nick from manufacturing or installation, or slight frame movement, and they tend to spread over time even without a direct hit.
What is the difference between tempered and laminated glass?
Tempered glass shatters into small, less dangerous pieces when broken. Laminated glass holds together via an inner layer even when cracked, which is why it is often specified for higher-security or sound-control applications.
Why is one pane of the window foggy?
This means the seal on an insulated glass unit has failed and moisture has gotten between the panes. The whole unit needs replacement since the seal cannot be repaired.
How fast can a broken storefront panel be boarded up?
Most commercial glass providers offer same-day or overnight board-up service, with the permanent glass replacement following once the correct panel is sourced.
