FREQUENTLY ASKED QUESTIONS

Tempered glass is heat-treated to be 4-5x stronger than standard glass and breaks into small, dull granules. Laminated glass consists of two panes bonded by a plastic interlayer; if it breaks, the glass stays intact. We recommend laminated glass (like Riot Glass) for maximum security against forced entry.

Once we have measured your window, a custom-sized insulated glass unit (IGU) typically takes 3 to 7 business days to fabricate. The actual installation by our expert glaziers usually takes less than an hour per window.

Absolutely. We specialize in large-format, wall-to-wall custom mirrors for home gyms, yoga studios, and Pilates spaces. We use professional-grade mirror mastic and safety clips to ensure a secure, distortion-free installation.

Yes, San Jose Glass is a specialist in high-security glazing. Riot Glass is an invisible, shatterproof shield that protects businesses from "smash-and-grab" burglaries. It is much more effective than standard tempered glass and doesn't require unsightly bars or shutters.

Condensation between the panes indicates a seal failure. When the hermetic seal of an Insulated Glass Unit (IGU) breaks, moisture enters the gap, causing a "foggy" appearance. We can typically replace just the glass unit without needing to replace the entire window frame.

Low-E (Low Emissivity) glass has a microscopic coating that reflects infrared heat. This keeps your home cooler in the summer and warmer in the winter, which is essential for energy efficiency and reducing utility bills in the San Jose climate.

Yes. We offer free, no-obligation estimates. For most projects, you can call us with rough measurements or send photos of the damage/project site. For custom architectural glass and shower doors, we schedule a professional site visit to ensure precision.

If the window frame is in good condition, glass-only replacement is significantly cheaper and faster than a full-frame replacement. You save on material costs and labor while still achieving the benefits of new glass (such as better insulation). However, if the frame is rotted, warped, or leaking air, a full replacement is a better long-term investment.

Yes. When installed by a professional like San Jose Glass, we use tempered or laminated safety glass that is incredibly impact-resistant. There are no large gaps or horizontal "ladder-effect" rails, making them safer for children and pets than traditional railings.
