Alex called to let me know his ETA, and he and Ali worked rapidly and efficiently for three straight hours to cut, fit, install, and clean up. Despite the hard work and labor, he was courteous and friendly the whole time. I highly recommend Glass Express and Glazing Service.

Frequently Asked Questions
Yes, we are proud to offer same-day glass replacement for broken or damaged glass on windows, roof lights, and other glazed fixtures. We understand that shattered glass can pose immediate safety hazards, compromise security, and cause inconvenience or disruption to your property. Our mobile teams are equipped with a wide selection of stock glass types and sizes, allowing us to quickly assess the damage onsite, safely remove the broken glass, and install a new, high-quality pane usually within hours of your initial call. This rapid response service is designed to minimize your downtime, restore safety, and ensure your property remains weatherproof and secure as swiftly as possible. We also prioritize urgent cases such as break-ins, storm damage, or accidents, providing peace of mind that your property is protected without delay.
We replace a broad spectrum of glass types to suit various structural, safety, security, and aesthetic requirements. This includes standard clear float glass suitable for internal and external glazing, toughened safety glass designed to shatter into small, blunt pieces for safety, laminated security glass that remains intact when broken, double and triple-glazed units for insulation and noise reduction, acoustic glass for soundproofing, tinted or reflective glass for privacy or heat control, and decorative patterned glass for aesthetic enhancements. For roof lights, we also supply specialized low-iron or UV-protective glass, which maximizes light transmission and reduces UV damage. Our team can advise on the best type of glass for your specific application, ensuring durability, safety, and energy efficiency.
If your window or roof light shatters after hours, your first priority should be safety, security, and preventing further damage. We provide 24/7 emergency glazing services, so you can contact us at any time. Our rapid-response team typically arrives within 1 to 2 hours, equipped with the necessary tools and stock glass to perform emergency repairs. We will secure the area by temporarily boarding up the damaged window or roof light with sturdy, weatherproof materials to prevent weather ingress, unauthorized access, or injury from shattered shards. Once the immediate danger is mitigated, we arrange to replace the broken glass as soon as possible—usually the next working day—restoring your property’s safety, security, and insulation without unnecessary delays.
Deciding whether you need a repair or a full replacement depends on the extent of the damage and the integrity of the existing glazing. Small chips, minor cracks, or hardware issues like handles and hinges are often repairable without replacing the entire unit. However, if the glass is shattered, has large cracks, or if the seal around the unit has failed—causing condensation, fogging, or loss of insulation—then a full replacement of the glass unit is generally the most effective long-term solution. Our experienced technicians will carry out an on-site assessment, examining factors such as safety, energy efficiency, and security, and advise you whether a repair is sufficient or if a full replacement will provide better value, durability, and performance.
Yes, we install new roof lights, including fixed skylights, roof windows, and ventilated roof lights, tailored to your specific needs and architectural style. Whether you’re looking to add natural light to an extension, loft conversion, or new build, our team provides professional installation services. We work with a variety of styles, sizes, and glazing options to ensure your roof light is secure, weatherproof, and compliant with building regulations. Our installation process includes proper sealing, flashing, and waterproofing to prevent leaks and drafts, ensuring your new roof light remains durable and energy efficient.
Absolutely. If your existing roof light is cracked, broken, or leaking, it can be safely replaced to restore both the aesthetics and functionality of your roof. Our team carefully removes the damaged unit, inspects the surrounding roof structure for any damage, and installs a new, high-quality roof light that matches your specifications. We use weatherproof sealing and flashing techniques to ensure the installation is fully weather-resistant. Replacing damaged roof lights not only improves the appearance of your roof but also enhances insulation, reduces heat loss, and prevents leaks, extending the lifespan of your roofing system.
Yes, roof lights are one of the most effective ways to maximize natural daylight in your property. They are especially useful in spaces with limited wall windows, such as attics, loft conversions, or internal rooms. Properly installed roof lights can flood your interior with daylight, creating a brighter, more welcoming environment while reducing reliance on artificial lighting during daytime hours. They also help improve ventilation when combined with opening mechanisms, contributing to better air quality and comfort.
Modern roof lights are manufactured with energy efficiency in mind. They often feature low-emissivity (Low-E) coatings, multi-layered insulating glass, and argon or krypton gas fills that significantly reduce heat transfer. These features help keep your property warmer in winter and cooler in summer, lowering energy bills and reducing your carbon footprint. When installing or replacing roof lights, we recommend energy-efficient glazing options to maximize insulation, minimize heat loss, and prevent drafts, ensuring your space remains comfortable year-round and your energy costs stay low.
Yes, we replace cracked or broken roof light glass promptly. Whether the damage is minor or severe, our team assesses the extent of the crack, removes the damaged glass carefully, and fits a new high-quality panel. We ensure that the replacement glass is properly sealed and weatherproofed, restoring the roof light’s performance and preventing leaks or drafts. Using durable, specialized glazing suitable for roof applications, we guarantee a long-lasting, secure solution.
Yes, our services include the installation, repair, and replacement of flat roof lights, also known as skylights or roof windows. We work with a variety of sizes and styles suitable for flat roofs, ensuring they are properly sealed, weatherproofed, and compliant with building regulations. Whether you’re adding a new skylight or replacing an existing one, our team ensures the installation is durable, energy-efficient, and aesthetically integrated into your roof design.
Absolutely. Proper weatherproofing is a critical part of our installation process. We use high-quality flashing, sealants, and waterproof membranes to ensure that your roof lights are fully protected against water ingress, drafts, and weather-related damage. Our technicians follow best practices and manufacturer specifications to create a secure, weather-resistant seal that maintains the integrity of your roof over time. This ensures your roof lights remain durable, energy-efficient, and free from leaks, even during heavy rain or storms.
