Window glass repair covers everything from replacing a single broken pane in a vintage wood-frame window to swapping out a failed insulated glass unit (IGU) in a modern vinyl or aluminum frame. Foggy windows — caused by a broken seal between dual-pane glass — are the most common repair in NorCal homes 10-20 years old. Rather than replacing the entire window, we can replace just the glass unit (IGU), saving 40-60% compared to full window replacement. We also handle tempered glass, laminated safety glass, and obscure (privacy) glass for bathrooms.

Union City is located in Alameda County (East Bay). Diverse suburban city between Fremont and Hayward with 1970s–2000s family homes. The local utility provider is PG&E.

Window Glass Repair in Union City — FAQ

Should I repair the glass or replace the whole window?+

If the window frame is in good condition, replacing just the glass (IGU) saves 40-60% compared to full window replacement. If the frame is rotted, warped, or the hardware is failing, full replacement is the better investment.

Why are my dual-pane windows foggy?+

Foggy dual-pane windows indicate a failed seal between the glass panes. Moisture enters the gap and condenses inside. The only fix is replacing the insulated glass unit (IGU) — the glass cannot be cleaned between panes.

How much does window glass repair cost?+

A dual-pane IGU replacement costs $150-$400 per window in NorCal depending on size and glass type. Single-pane reglazing on older windows costs $75-$200 per pane. Tempered or specialty glass costs more.

How long does window glass repair take?+

Once the replacement glass is received (1-5 business days for custom IGUs), the actual glass swap takes 30-60 minutes per window on site.
