When the glass in your sliding glass door is shattered, cracked, or foggy from a failed seal, you do not need a new door. We measure your panel, custom-order a new dual-pane insulated glass unit (Impact-rated and Low-E available), and swap it into the existing frame in one return visit. This is glass-only — we don't replace the door system or install new windows. In St. Augustine, old city and davis shores properties see moderate salt exposure from the matanzas; inland st. augustine properties hold up well.
Glass-Only Replacement symptoms we see in St. Augustine
- Glass is cracked or shattered (we'll board it up same-day if needed)
- Foggy or cloudy glass that won't clean off - failed seal between panes
- Visible moisture or water droplets between the two panes
- White haze or mineral deposits inside the glass
- Reduced visibility through the door even after cleaning
- Energy bill spiked because the Low-E coating has degraded with seal failure
- Storm damage or impact crack from debris
