A broken storefront panel or shattered entry door is a security exposure and a safety hazard that needs to be handled the same day. Emergency commercial glass repair throughout Santa Clarita by Preferred Glass & Windows — AAMA-certified, no subcontractors, since 1969.
Call us any time a broken or compromised opening leaves your business exposed. Common causes include break-ins and attempted forced entry, storm debris and windborne impact, vehicle strikes against storefront systems, vandalism, and sudden tempered glass failure. Any opening that compromises security, safety, or climate control warrants immediate response.


Restrict access to the damaged area and keep staff and customers clear of loose fragments. Do not disturb cracked tempered glass that is still in place. Tempered glass under tension can release unexpectedly.
These examples reflect common conditions we see across specific areas. We provide the same level of service to every property throughout the Santa Clarita and San Fernando Valleys.
Our first priority is containment. Unstable glass is removed methodically and debris is contained before boarding begins. Board-up panels are anchored into structural framing, not surface trim. A board-up that is not properly anchored will shift under wind pressure and create additional frame stress or security vulnerability.
For aluminum storefront systems, temporary infill panels or reinforced coverage are used depending on frame condition and opening size. If an entry door frame has been distorted by impact, adjacent mullions may need to be addressed to maintain perimeter integrity.


Once the opening is secured, we assess what permanent repair requires. If the frame is sound, glass-only replacement is usually the right call. Storefront lites and entry door panels are replaced to match the original safety classification, thickness, and coating spec.
Replacement units for insulated storefront systems have to match original thickness, spacer configuration, and coating type. A mismatched panel creates visible inconsistency across the storefront elevation. We confirm all specifications before ordering so the permanent replacement looks correct and performs correctly from day one.
We provide measurements, glass specifications, photographs, and repair details to support commercial insurance claims. Documenting glass type, frame condition, and damage cause at the time of service gives you what you need for claim processing without requiring a return visit.

Local readers and publications including the LA Daily News and The Signal have consistently recognized us as the top glass and window company in the region.

Lead time depends on glass type and coatings. Standard tempered lites are typically faster than specialty insulated or coated units. We confirm the timeline after the site assessment and keep you informed throughout fabrication.
Yes. Replacement glass has to maintain the same safety classification as the original. For insulated storefront units, thickness, spacer configuration, and coating type all have to match. We verify all specifications before ordering.
Frame condition is assessed as part of every emergency visit. If the frame has been distorted or anchor points compromised, we address that as part of the permanent repair plan. A new glass panel installed in a damaged frame will not perform correctly.
I loved going with Preffered Glass as it was recommended by a family friend to fix my antique hutch cabinet. I spoke with Courtney and I needed 2 new pieces for my doors. She was great she got the measurements I needed and what I wanted. She got the work done same day. And when I installed the pieces one needed to be cut a little more because it was a little to big. She personally went to the back and cut the piece I needed so it can fit properly. 10 out of 10 recommend for all your Glasswork needs.
Preferred Glass & Windows is an amazing company to work with beginning to end on any project! Scott came to my house to give me a quote on shower doors for my master bath and on all my windows. He was extremely professional and helpful and made sure everything went smoothly! Courtney at the front desk was super friendly as well and very knowledgeable and she had no problem answering any of my questions! The customer service was top tier and the installation job was even better! I will definitely be a returning customer.
We had a broken window called for service to replace it. They came the next day measured the window said it would be a week or two to get the window call the next day.
