Glazing emergencies strike without warning. Whether it’s a broken window caused by severe weather, attempted break-in, or accidental damage, knowing exactly what to do in those crucial first moments can prevent further damage, protect your property and ensure the safety of occupants.
This comprehensive guide walks you through the essential steps every property manager, developer and trade professional should know when facing emergency glazing situations.
Time is critical in glazing emergencies. Industry data shows that properties with broken glass face security risks within hours, while unprotected openings can lead to water damage, energy loss and structural integrity issues. The faster you take appropriate action, the better you can protect your investment and minimise costly repairs and safety risks.
At SGC Glass, our 24/7 emergency glazing service across London, Essex and surrounding areas has responded to countless glazing emergencies since 1995. Our experience shows that prompt action combined with professional help makes all the difference in emergency outcomes.
Immediate safety measures: Your first priority
When confronted with broken glass, safety must come first. Glass shards pose serious injury risks, while exposed openings create security vulnerabilities and weather exposure problems.
Essential safety steps:
- Clear the area immediately: Keep people, especially children and pets, away from broken glass
- Avoid touching glass fragments: Even small pieces can cause severe cuts
- Wear protective footwear: Never walk near broken glass in bare feet or soft shoes
- Switch off electricity: If glass damage affects electrical fittings or wiring
- Document the scene: Take photos for insurance purposes before cleaning begins
Never attempt to remove large glass pieces yourself. Professional emergency glaziers have the proper equipment and training to handle dangerous glass fragments safely.
Assessing the extent of the damage
Understanding the full scope of damage helps you communicate effectively with your emergency glazier and insurance provider. Different types of glazing require different repair approaches and timescales.
Key damage assessment points:
- Window frame condition: Check if the frame is intact or if structural damage extends beyond the glass itself. Damaged frames may require more extensive repairs.
- Glass type identification: Single glazing breaks differently than double glazing. Sealed unit failures in double glazing may not be immediately obvious but can compromise energy efficiency.
- Security implications: Ground-floor windows and shopfronts create immediate security risks that require urgent attention.
- Weather exposure: Openings facing prevailing winds or rain need faster protection to prevent internal damage.
- Size and accessibility: Large windows or high-level glazing requires specialist equipment and techniques for safe repair.
Temporary protective measures you can take
While waiting for professional help, appropriate temporary fixes can prevent further damage and improve security. However, these are short-term solutions that should never replace proper glass repair.
Safe temporary protection options:
- Plastic sheeting: Heavy-duty plastic can provide weather protection for smaller openings. Secure firmly to prevent wind damage.
- Plywood boarding: For larger openings or security reasons, properly fitted boards offer better protection than plastic sheeting.
- Duct tape: Only suitable for small cracks to prevent spreading. Never use on large breaks or security glazing.
- Clear polycarbonate sheets: Temporary solution that maintains some visibility while providing weather protection.
Remember that temporary fixes should only be used until professional emergency window repair can be completed. They don’t provide the same security, weather protection or energy efficiency as proper glazing.

How quickly should you expect professional response?
Response times matter in glazing emergencies. Industry standards show that professional emergency glazing services typically aim to reach properties within a few hours of initial contact.
SGC Glass operates 24/7 emergency services with strategically positioned teams across London, Essex and surrounding areas, ensuring rapid response when you need it most. Our goal is on-site attendance within hours, not days, minimising security risks and preventing further damage.
Common glazing emergencies and responses
Different emergency situations require different responses. Understanding common scenarios helps you take appropriate action and communicate effectively with emergency services.
Storm damage and severe weather
High winds can cause multiple window failures simultaneously. Severe weather emergencies often require rapid boarding up services to protect entire buildings while replacement glass is sourced.
Break-in attempts and vandalism
Security glazing failures need immediate attention due to ongoing crime risks. Emergency glaziers can install temporary security measures while sourcing appropriate replacement security glass.
Seal failure in double glazing
Though less dramatic than broken glass, seal failure compromises energy efficiency and can lead to costly energy bills. Professional assessment determines whether immediate repair is necessary or if temporary measures suffice.
Structural movement damage
Building settlement or structural issues can crack glazing systems. These situations require careful assessment to address underlying causes alongside glass replacement.
Types of emergency glazing repairs
Emergency repairs vary significantly depending on glass type, location and damage extent. Understanding different repair approaches helps set realistic expectations for timescales and costs.
Standard window glass repairs
Single pane windows are typically quickest to repair, with emergency glaziers often carrying stock sizes for immediate replacement. These repairs can usually be completed within hours.
Double glazing emergency repairs
Sealed unit failures or complete breakages require specialist materials and techniques. Some repairs may need temporary boarding while replacement units are manufactured to exact specifications.
Commercial and security glazing
Shopfronts and commercial glazing often use specialist glass types requiring particular expertise. Emergency glaziers should stock common commercial glazing materials for rapid response.
Fire-rated and safety glazing
Specialist glazing systems need exact replacements to maintain safety certification. Emergency repairs may require temporary solutions while sourcing compliant replacement materials.
Preventing future glazing emergencies
While some emergencies are unavoidable, regular window maintenance can prevent many common problems. Professional glaziers can identify potential issues during routine inspections.
Preventive maintenance recommendations:
- Annual frame inspections: Check for wear, movement or seal deterioration
- Regular cleaning: Proper cleaning reveals developing problems early
- Weather seal maintenance: Replace worn seals before water penetration occurs
- Security film application: Additional protection against impact damage
- Professional assessments: Expert evaluation of high-risk glazing installations
SGC Glass provides comprehensive commercial repair services and maintenance programmes to help prevent emergency situations developing.
